Good teams are made of people and things. I build them —
as solid as necessary, as fluid as possible.
My specialty: bringing people together through artifacts.
A shooting schedule gets thirty people through a day, a
report puts business and IT at one table — and this page
turns a CV into a conversation. Screenplays and websites at
the start, SQL, data models and my own Power BI visual
today — those are only the ends of the journey. The core
has stayed the same: understanding what needs to happen
between people, and building the thing that makes it
happen.
Two part-time roles, one craft: data models that business
departments actually use.

Systems Analyst — Product Engineering & Product Management
XAL GmbH, Graz (lighting industry) –
Led the Power BI committee (2022/23): planned a new
data-warehouse architecture on the Microsoft stack — two ERP
systems, PIM and SharePoint as sources; models and reports in
Excel and Power BI (SQL, SSAS); coordination of DWH
changes via Azure DevOps.
Project lead for the introduction of the new EU energy
labels (2020–2022).
Product owner of the in-house PIM (2016–2023;
Django/Python/PostgreSQL; backend of the product website
with more than 10,000 products).
Built and rolled out many small tools — Excel, Power BI,
Power Automate, Power Apps, SharePoint, SmartSheet; and
analogue: pin boards, cards, flip charts.
Organisational development of new roles and processes in
product development (2016–2018).
A year working for myself — and the fastest school I ever attended.
Founder
Forgetit.io –
Built a time-management app. An intense year in the start-up
community — lean startup, agile, Kickstarter, social media.
Grew out of the Gründungsgarage at the University of Graz.
Project management first, then seven years at the University of
Graz — business studies, sociology, start-up garage — and finally
teaching others.
University
University of Graz2008 – 2015
Business studies, sociology, start-up garage.
Getting in came first: the university entrance exam
2008 – 2010, taken without a school-leaving
certificate. Then three semesters of business studies
(2010 – 2011, 45 ECTS) and the move to sociology
(2011 – 2014, exams worth 168 ECTS, no final
thesis). Finally the Gründungsgarage at the Institute of
Corporate Leadership and Entrepreneurship (2014 – 2015),
where the iOS app “Forget it!” took shape —
and led to founding Forgetit.io in 2015.
Generalist Project Manager
Activity2006 – 2007
Two-semester programme of 1,175 hours.
Systemic project management, NLP, plus basics in accounting,
controlling, labour law and coaching.
Before data came film: five years in production, unit management and
art department — project management under real-time conditions.

Production & Unit Management
Unit management means the shooting schedule is your
product. Who stands where and when, whether catering
arrives before the lunch scene, what happens when the lead
is stuck in traffic — and the deadline is called wrap,
every single evening. On the ORF documentaries I also
planned whole productions;
“Zwischen-Pass” was my own film, from
script to cut.
“Erlebnis Österreich: Der Schöckel” — documentary, ORF; RAN-Film09 – 12/2007
Director, Writer & Editor
“Zwischen-Pass” — my own short film06 – 09/2006
Assistant Unit Manager
“Oneline Life: Play Hard Go Pro” — documentary
Set Unit Manager & Art Department
“Jenseits” — feature film06 – 07/2005
Assistant Unit Manager
“Shiver: Stehst Du still” — music video
Assistant Unit Manager
“Wie Schnee hinter Glas” — short film
Art Department & Props
Started as an intern in interior props, at Bayerischer
Rundfunk. The art department is the craft behind the
picture: every object in the frame was put there by
someone. You learn lists, logistics and an eye for what
makes a scene believable. In the model only a quarter of
these hours count as project management — carrying props
is craft, not coordination.
Set Props
“Oben Ohne” — TV series, ORF; Star*Film
Set Props
“Novotny & Maroudi” — TV series, ORF08 – 09/2005
Set Decorator
“Heile Welt” — short film
Art-Department Internship, then Set Props
“8x45: Bis in den Tod” — TV series, ORF01 – 03/2005
Props Assistant (internship)
“In einem anderen Leben” — TV movie, BR12/2003 – 01/2004
The same skills, calculated rather than claimed: an hour of
learning counts as two hours of practice. Exactly two curves
cross the line at 10,000 — the two with five stars.

Project Management
Learned on film sets, where the schedule is the product and wrap is a daily deadline: thirty people, one plan, and when the weather turns, the whole day turns with it. Do that for a few years and you can manage projects before you ever use the word.
The theory came in 2006 — two semesters of systemic project management at Activity, IPMA Level D; the course also led to radical constructivism and, via Gareis, to business studies. Then Scrum at the startup, most recently the EU energy-label rollout at XAL: one project across the entire company.
Business studies left a gap: between what the textbook says and what actually happens inside a company. The textbook runs to a thousand pages, and the gap isn’t in there. Mintzberg closed it — he describes management the way it looks when you watch it.
The practice came at XAL: organisational development in product development, product owner of the in-house PIM, the Power BI committee, certified apprenticeship trainer. Current trail: complexity science and the edge of chaos — how much order a company needs, and how much movement.
The fastest school of marketing: at the Gründungsgarage we designed an app nobody had asked for — when nobody buys, no theory will save you. The app became Forgetit, and Forgetit became two years of running a startup: lean startup, pitching, Kickstarter, social media.
Today I sit on the other side of the table: at Neuroth I build data models from the marketing perspective — the same questions, answered with data instead of gut feeling. This spring the theory caught up: Sharp’s “How Brands Grow”, Binet & Field.
Daily since 2016: star schemas, DAX, SSAS, Fabric — eight years of XAL, now Neuroth and Supernova, plus the Python backend of a product website with more than 10,000 products. The point of it all: data models that make the connections visible.
Books barely cover this field; what I know comes from doing it, and from the web — above all Guy in a Cube. One book stands out: Wilkinson’s “The Grammar of Graphics”. It became ggpbi, my own Power BI visual.
Almost all of it from university: the lectures, the exercise classes that went with them, later whatever the job calls for. The textbook is still on the shelf — Bamberg, Baur and Krapp, read in 2010, the business-studies year.
It’s a field where I know pretty precisely where my limits are — and I prefer that to a field where I don’t. Kahneman and Silver came much later, as context rather than foundation.
The screenwriting books came before the films, not with them: Field, McKee, Aristotle, Mamet, Freud’s “Jokes” — all before 2003. First read, then shot: five years of film were the practice.
The thickest book in the column isn’t about writing at all — in 1,250 pages of “War and Peace”, Tolstoy runs a hundred characters without losing one. Today the craft builds reports that someone understands, and at best remembers. A dashboard is a story too, just shorter.
The youngest field and the only one without a single book — no book could keep up. What I know comes from daily use: at work, at home, everywhere.
The learning happens on YouTube, in a pattern noticeably different from Power BI: there, one channel with eighty-three videos; here, many channels with two or three each. That’s what learning looks like before a field settles — you don’t subscribe, you observe.
It started with a door-closer: in thirteen pages Latour describes how a piece of metal takes over a doorman’s job — after that, sociology stopped being a subject and became a lens. The trail before it: Chinese medicine and its thinking without cause and effect, then constructivism via the project-management course.
Three years of sociology at university, no degree — the lens stayed. Becker taught me how to write, Latour how to follow networks; complexity science is the current trail. Grown from the books, so it carries no stars: the shelf is the rating.
Eight years of secondary school in a single year, alongside a job — the university entrance exam only works with a system, and “Getting Things Done” provided it. The second time was the startup: too little time for too much.
At the end of the XAL years came the Stoics, via audiobooks — Marcus Aurelius sits at the very top of my ranking, right next to Tolstoy. Two thousand years old, and closer to GTD than either side would admit. Also grown from the books — no stars.
Deep into AI since 2023, professionally and privately —
from prompting to the question of what the models are
doing to our work.
Systems Theory
Gareis’ “Happy Projects!” kicked off my interest in systems
theory. It was also the decisive reason to enrol in business
studies — and later to switch to sociology.
“The Web That Has No Weaver” showed me a lot about the
holistic thinking of Asian theories. TCM and feng shui work
fine without our cause-and-effect thinking.
Making Data Visible
My CV as a data model: timeline, competence curves, an
interest budget — computed instead of claimed.
I am not what I read. But what someone reads says a lot about them.
So I tried to reconstruct which books shaped me — print and audio, going back to school days. And then asked the question you can only ask once they all lie side by side: which book gave the most for its pages?
Sociology
Philosophy & Stoicism
Management
Film & screenwriting
Systems thinking
Psychology
Data & technology
Literature & biography

Always theory-driven: it began with American screenwriting theory, built on Aristotle’s Poetics — then systems theory and Asian classics, then actor-network theory, Mintzberg, lately complexity science. The mix fits wherever people are connected through artifacts. Here’s the journey — skipping allowed.
Storytelling
The screenwriting books came before the films, not with them: Field, McKee, Aristotle, Mamet, Freud's "Jokes" — all before my military service in 2003. First read, then shot. Five years of film were the practice.
The thickest book in this column isn't about writing at all: "War and Peace". In 1,250 pages Tolstoy shows how to run a hundred characters without losing a single one.
Today the craft serves something else: building a report that someone understands — and, at best, remembers. A dashboard is a story too, just shorter.

My first project wasn't called a project. On a film set it's called the call sheet: thirty people, one shooting schedule, and when the weather turns, the whole day turns with it. Do that for a few years and you can manage projects before you ever use the word.
The theory came in 2006: two semesters of systemic project management at Activity, IPMA Level D. The course gave me more than the certificate — it led me to radical constructivism, and Gareis' "Happy Projects!" is why I enrolled in business studies. Then Scrum at the startup, and most recently the EU energy-label rollout at XAL — one project cutting across the entire company.

My business degree left me with a gap: between what the textbook says and what actually happens inside a company. The textbook runs to a thousand pages, and the gap isn't in there.
That's exactly why I read Mintzberg in 2018 — he describes management the way it looks when you watch it, not the way it's supposed to look. Before that, in the move from the startup to XAL, I had read my way into organisational development.
The next layer of this is complexity science — more on that below, at the end of the path.

The theory came from three methods courses in my sociology degree. Sounds like little, but it was exactly the right thing: preparing data, analysing it, presenting it — on real questions, not textbook examples.

Where things are heading right now: complexity science. I read West's "Scale" this spring — scaling laws that hold for organisms, cities and companies alike. A mouse, a city and a corporation follow the same curves, just with different exponents.
What grips me is the edge of chaos in organisations: the zone between order and chaos where a system is most adaptable. Too much order and nothing moves. Too much chaos and nothing holds.
This is where the threads from above come together: systems theory from sociology, Mintzberg's view of organisations — and the data you'd need to measure it one day. Maybe that's the next phase. The books are already piling up.
My own open-source project · TypeScript & D3 · MIT licence ·
github.com/efelcie/ggpbi · Last updated
ggpbi is an open-source Power BI visual that brings the
Grammar of Graphics from ggplot2 to Power BI — written
in TypeScript and D3, with no R or Python runtime.
Power BI ships a fixed list of chart types. Anyone who needs
something else reaches for an R or Python visual — those need
an installed runtime and end up delivering an image: no
cross-filtering, no native tooltips.
ggpbi takes the other route. It brings the grammar of ggplot2 to
Power BI — fields map to aesthetics, geoms stack as
layers — but as a native TypeScript/D3 visual. No runtime, no
R, no Python. It renders as fast as any built-in visual and works
in the Power BI Service.
Three ggpbi visuals in one report, on the iris data set: scatter
plot, density curves per species, box plots. Cross-filtering and
tooltips like any built-in visual — no R, no Python, no
runtime.
A report like this is built by dropping fields into wells; the
Format Pane writes the ggpbi chain from them. And the
other way round: since version 0.5 the code view is a real
editor, with an optional vim mode. What you change there writes
back into the Format Pane — editor and pane are two doors
into the same room. The editor speaks three languages: the ggpbi
chain, ggplot2 in R, and ggpbir, the report’s JSON format.
And outside Power BI
ggpbi is an ES module with D3 underneath — Power BI is one
of the places it runs, not the only one. Both charts on
this page are drawn with it: the hours
up in the skills section and the
book matrix. And really with it
— the code below is exactly what draws them, not a simplified
example. The library loads only after the page is up; until
then a static SVG stands in — and stays put if anything goes
wrong.
Two charts, the same chain. ggpbi drops empty labels —
which is why only the fifteen most important books carry a
title, and repel pushes them apart until none
covers another.
What’s in it
Geoms: point, line, bar, col, area, text, boxplot,
violin, histogram, density, smooth (lm, loess, moving average),
segment, pointrange, plus the reference lines hline, vline and
abline.
Grammar: aesthetics (x, y, color, fill, size,
shape, alpha, group, label), positions (identity, stack, dodge,
fill, jitter), scales (linear, log, sqrt, time, category) with
locale-aware number and date formats, faceting by row and column,
and gghighlight-style highlighting.
Power BI native: cross-filtering by click,
native tooltips, context menu, report themes, high-contrast mode
and style presets.
Two fields are enough to start: one in X, one in Y. ggpbi picks the
geom from the scale types — number and number give a scatter
plot, category and number a bar chart, date and number a line, a
number on its own a histogram.
Status: version 0.5.0 — about 16,000 lines of TypeScript
across 51 modules, 67 test files. Not on AppSource yet; it installs
by file import in Power BI Desktop.
I ported the same core — scales, axes, label engine —
to Elm, to see what survives of the grammar when the compiler
flags every gap. The chart above is the TypeScript version.
