"We don't write the rules. We just discover them. (With AI.)" — discovering scheduling heuristics with an LLM autoresearch loop
A job-shop scheduling problem dressed up as a lunch rush: one grill, one shared range, and sequencing as my only lever. Rather than hand-write the rule, I let an agent propose candidates, run them across simulated services, and keep whatever beat the champion — trained on six scenarios, then held out against three more to check it found a principle, not a memory. Built on Nima H. Siboni's "The Heuristic Scientist: Open-Ended Algorithm Discovery with LLMs" workshop.

"Which city in Paris are you staying in?" - Can a phone-sized model learn to ask frontier-quality questions? Can they? Do they? Let's find out!
Across 96 experiments — every prompting, retrieval, decoding, pipeline, fine-tuning, preference-learning, reinforcement-learning and adversarial-distillation lever we could find — an on-device 3B model came within about one rubric point of a frontier cloud model on every quality dimension: close, but consistently a notch below, across the board.

Gablonzer Strasse 23
Come back with me to the house I grew up in near Frankfurt, and to the day — my thirteenth birthday — I came home from school to find the trees cut and half of it already gone. It's about home, and how quietly you can lose one.

Wings Of Desire
It was 1999, I'd just turned twenty and moved to New York, when I fell for a woman more than twice my age. This is the story of the three days we stole in Berlin, and of watching her taxi disappear and knowing it was complete.

How to Make Big-Ass Bubbles
After months of trial-and-error and dozens of recipes, I've got the giant-bubble solution and wands that work for me on both sides of the Atlantic. I'll hand you everything I learned so you can go make some absurdly big bubbles of your own.

My mother's death in 2018
Losing my mother to cancer was a slow-motion car-crash stretched over ten years. Here's the phone call I'd dreaded for a decade, which came as I was boarding a flight to her — and my father, singing her favourite song as she passed.

Your amazing YOUness
Your YOUness — every book you've read, person you've met, pain you've suffered and joy you've found — makes you a one-in-a-billion event in all of time and space. Here's my case for going and discovering yours, written while I was busy collecting mine.

A few career highlights — the projects and ventures I'm proudest of.

Freakonomics Experiments
Let a coin decide — then measure what happens.
As senior engineering consultant, I designed and shipped the infrastructure for a truly randomized, multi-month, large-scale field experiment for Prof. Steve Levitt of Freakonomics — the engine behind his 2020 "Heads or Tails" study on how a coin toss shapes big life decisions and happiness.

OneMonth Inc.
From zero to shipping code in a month.
My technical co-founder run: I designed and wrote a best-selling "programming for non-programmers" video course that got complete beginners shipping real code in a month — earning us a spot at Y Combinator and profitability since 2016.
Highly profitable from day one, and still selling · $2.5M raised

Venture Assembly
The metrics VCs never share, pooled.
Here, again as technical co-founder, I built and scaled a private data-sharing network for the "impossible-to-get" metrics VCs and their founders rarely pool — part of onboarding at 42 of the top venture firms in the US and Israel, supporting 359 founders' marketing, sales and hiring calls.

Pivotal Labs, New York City
Coaching teams to ship better, faster.
Working as senior technology consultant, I coached client teams to ship better products faster through lean experiments, pair-programming and test-driven development. One team used live data from 250,000 trucks to preempt supply-chain failures — averting losses in the millions.

Unblah
Know when to speak up — and when to zip it.
Ever leave a meeting wondering if you talked too much — or never got a word in? I built Unblah to quietly show your talk-time as it happens, so you can catch yourself in the moment and hit the balance you're aiming for. It works across Zoom, Teams, WebEx and calls, and never records or shares a thing.

Streamline
Brain-dump first. Organize later.
I wanted a calm, blank space to get my thoughts out before the day's noise set in — no menus, no formatting, no friction. As you write, Streamline surfaces your existing notes so a morning brain-dump connects straight into the system you already keep. Everything stays on your machine, with no account and nothing tracked.

JamGPT
ChatGPT, one keystroke away.
JamGPT gets you to ChatGPT the instant you need it — one keystroke from whatever app you're in, with no tab-hunting or logging back in. I kept my go-to prompts a click away for the things I do over and over, like translating or tightening up a sentence. It's free to use, and ready the moment you download it.

Pudding
Proof you actually wrote it.
In a world that assumes everything's written by AI, I made Pudding to let you prove the words are yours. It captures your writing as it actually happened — every edit, pause and rewrite — so you can replay the whole process and hand anyone undeniable proof of your work. Peace of mind for students, writers and freelancers who get asked, "did you really write this?"

Algorand Ballet
Watch the money move on-chain.
My open-source OSINT tool for the Algorand blockchain. See who a wallet really deals with: drop in any account and watch its activity unfold as a map you can explore — follow the connections, spot the patterns, and dig into any account, asset or app with a click. I built it as a simple way to do your own homework before you trust, invest, or just satisfy your curiosity.

Pudding Research
Connect the dots, follow the money, find the story.
Another open-source OSINT tool I made, this one for Ethereum token ecosystems. Pick any token and instantly see where the money flows — who's moving it, to whom, and how much. The biggest players and tightest relationships rise to the top, so you can filter out the noise, zero in on what matters, and pull a real story out of the chain. Export what you find to share it. Try it.

Extract PDF Highlights
Turn your PDF highlights into notes.
I was tired of re-typing the passages I'd highlighted while reading. Now you open a marked-up PDF in Obsidian, click once, and every highlight, underline and note lands in a tidy page-ordered note you can actually search, link and build on. Hours of manual copying gone — your reading turns straight into usable notes.

Extract PDF
PDF in, Markdown out.
This one frees the text trapped inside a PDF. One click turns a document into clean, editable notes — headings, paragraphs and lists intact — so you can quote it, rework it, and weave it into your own writing instead of squinting at a locked-up file.

Journey
Find the story hiding in your notes.
You've collected hundreds of notes — but where's the story in them? I built Journey to trace a path between any two ideas in your vault and hand you a ready-made outline, surfacing connections you'd forgotten you made. A blank-page cure that turns your scattered thinking into the first draft of something worth publishing.

Footnotes
Footnotes without the bookkeeping.
I wanted to add a footnote without breaking my train of thought. One hotkey drops a numbered marker and its note at the bottom of the page, and the same key jumps you between the two — no counting, no scrolling, no losing your place. Footnote-heavy writing finally feels effortless.
