Career

Engineer, founder, consultant

Professionally, I worked both in small startups and big tech. I began as a Frontend engineer with strong opinions and a knack for sharing knowledge. Started to lead small to big teams and being responsible for product goals and coordinated execution.

At the same time, I'm a freelance consultant. Working with fund tax compliance, intelligent traffic start-ups and robotics companies. I'm good at finding effective solutions to challenging problems, and I do that quickly.

Coding

#7

I primarily code in Typescript. Depending on the task I also use Python and Rust. Always choose the right tool for the job. Most of the time that involves spinning up a new Tanstack Start project and self-hosting it on one of my Hetzner VPS.

Even in the age of LLM's I'm still driven by following good coding practices. The art of crafting an elegant solution to a complex problem just makes me happy. A good session is when I'm fully locked in and ship a new version at the end.

I self-host as much as I can to avoid serverless horrors. Hetzner Cloud is the best compromise between cost, performance and value.

I love coding in my free time. Usually I use Claude Code to build my side projects. The pre-AI era feels so far away already, it's difficult to imagine to ever write everything by hand again. That also means that I'm constantly on the verge to optimize my agentic coding workflow.

I open sourced my Claude Code setup as a plugin because I genuinely think it has some unique qualities. First of all, it automatically classifies each task by complexity: S, M, L or XL. It then spawns an appropriate number of subagents to do research, planning, execution and reviewing.

Check it out:

Claude Code is my main driver and it costs me $200 per month. It's well worth it because it gets so much done for me. I created a page to share more details about their AI stack (aistack.to). It grows into a nice community of like-minded builders.

Finance

I started 2016 with investing in stocks, ETF's and crypto. A very bumpy road, and I learned a lot in the process about trading psychology and strategies to cope with FOMO and FUD. I'm much more Zen than I was before.

I believe in portfolio diversification. Got some bucks in ETF's, stocks and crypto. I mostly invest in tech because i'm knowlegable in that field, but also in other areas.

Even held a presentation about this topic, but beware - it's in German.

Family

the five of usKODAK·GOLD

Family. Love my wife and three kids. They are the reason I stay motivated to grow as a person. I'm proud of our relationship. Trust, friendship and closeness is what I experienced as a kid from my parents and I'm trying to offer the same to my family.

I like Magic the Gathering. Created an app that helps me building decks, printing them and playing with my kids.

Travel

Exploring other countries and cultures is an absolute joy to me. We love to visit places with different culture, history and climate. We went to Thailand, Isreal, Mexico, Grenada and all over Europe. There is so much more to see.

My favorite moments are when we witness the raw reality of what a place is about. Touristic attractions can be fun, but I mean the actual land and people. Geocaching is a great tool to find the best local spots - even in your home town.

Next destination: Japan 2027.

Movies & TV

I watched more than a thousand movies and shows, at least those that I can remember. I love intricate stories, unique visuals and immersive worlds. Kind of similar of what I value in a good game.

My all time favorites are The Matrix (too bad they never made any sequels), Fight Club and Breaking Bad. I like dark humor, epicness and unexpected twists.

I built GoodWatch because I didn't want to go to IMDB, Metacritic, Rotten Tomatoes and JustWatch every single time when I was contemplating what to watch next. It became my biggest side project and is now a personalized recommendation engine for each user's personal taste.

ALL-TIME FAVORITES

Games

I played many games. Spent countless hours with simulations, arcade, jump'n'run, shooters, RTS and indie games. If you like Duke Nukem, Gordon Freeman, Jade, Kerrigan, Guybrush Threepwood or Scorpion, we can be friends.

The THPS 2 soundtrack is still on my rotation.

I'm in the exploration phase to build the very first massive multiplayer coop game. you build a pyramid together with thousands of other players. it might it turn out that you were part of something very different.

currently playing Witcher 3 (yep i never finished it) and expedition 33. next up is probably Baldurs gate 3

Music

I'm into music that radiates infinite energy. From Metalcore, over Progrock to Liquid D'n'B and Tech House. Loudness and high production value spurs me.

If it's well produced and expertly played, there are good chances that I'll like it regardless of the genre.

    At 16 I found my love for web development: HTML and CSS. There was no internet at home - my parents knew it would pull me away from school, so I had to finish first.

    I learned from SELFHTML on the school PCs and copied the pages onto floppies to keep going at home. Later, JavaScript.

    I got the keys to the PC room at school. I was responsible with them - and in the afternoons we played CS and StarCraft. My parents were proud I was staying late; they thought I was learning.

    I broke DOS and Windows constantly just to see what would happen, and made music in FastTracker - loved it.

GoodWatch

#Web App#Entertainment

Discover, track, and share movies and TV shows effortlessly.

Problem

Streaming is fragmented. Friends recommend titles you forget by Friday and surface-level ratings hide whether a show is actually for you.

Solution

A recommendation engine that understands your personal taste. It combines 70+ attributes like adrenaline, dark humor, dialog quality or cinematography into a unique fingerprint for each title. It blends critic scores, audience signals and your own watch history into trustworthy picks.

Outcome

GoodWatch ships continuously to a growing community of cinephiles who want fewer aggregators and better matches.

#AI#Community

Community-driven AI stacks: what people use, how they work and what it costs.

Problem

The AI tool space ships ten new launches a day. Most directories are SEO farms; none help you compose a working stack.

Solution

AIStack is community-driven: everyone shares their stack, how they orchestrate their agents and what it costs them per month. You learn about the most cost-effective ways to get best out of popular tools for your own setup.

Outcome

A growing community of agentic shippers.

Alfredo

#Self-Hosted#Open Source

Alfredo is the home for your projects. Your next one is live in minutes, with auth, email, database and analytics already wired.

Problem

Every new project makes you set up the same boilerplate again. You have an idea. Then the setup starts. You have built all of this before, and you will build it again. Or you rent it from five managed services and pay five bills for something you do not own.

Solution

Alfredo wires all of it once, on your own server. Your next project is live in minutes. Every project runs on your servers and reports to one HQ. You do not collect another set of dashboards every time you ship.

Under the hood

Alfredo is one program on one server. You point it at a plain Ubuntu 24.04 VPS, and it runs each project as a Docker Compose stack you can read. Alfredo uses three words for the pieces of that setup. It ships as a single binary compiled with Bun. Installing it is one curl command that pulls the release from GitHub.

#AI#Open Source

AI chamber for the modern engineer.

Problem

My agents run on a box at home. I do not. Knowing what is takeable, dispatching it, answering the one question a worker gets stuck on, and looking at what came out all live on the desktop I walked away from.

Solution

Curia is an always-on daemon that makes the phone a first-class client. It reads my GitHub trackers as its awareness source, dispatches a worker on a ticket into its own git worktree and tmux session, and bridges every question that worker has to Discord. Five verbs cover it: frontier, start, status, cancel, attach.

The golden thread

Phone → Discord → frontier → dispatch → escalate → answer → resolve → map → preview → attach, with one command spoken rather than typed. A preview link publishes the worker's dev server to the tailnet so the page opens on the phone; attach drops any device into the same live terminal session.

#Claude Code#Bash

Single-file Bash statusline for Claude Code: model, context, and rate-limit windows at a glance.

How to read it

The top half of each cell is how much of the window you have used. The bottom half is how much of the window has gone by. If the top reaches further right than the bottom, you are using it faster than the clock, and you will run out before it resets. Colour follows usage: green under 50%, yellow between 50 and 80%, red above 80%.

#Claude Code#Open Source

Complexity-aware agentic coding pipeline for Claude Code.

Problem

Coding agents misunderstand your intent, make wrong assumptions and write buggy code.

Solution

I open sourced my Claude Code setup as a plugin because I genuinely think it has some unique qualities. It automatically classifies each task by complexity: S, M, L or XL. It then spawns an appropriate number of subagents to do research, planning, execution and reviewing.

Outcome

The implementation results are way better, more accurate and match your actual intentions. Due to the amount of ceremony, time to finish and token usage both increase slightly.

How it works

Pick a task size

Pick a size above to run the pipeline.

Assumptions are not allowed, therefore every sessions starts with confirming my intent and interviewing me to actually understand the task at hand. Ideally, every goal is programmatically verifiable to guarantee success once it's done.

#MTG#Print & Play

Magic: The Gathering deck builder and print assistant

Problem

Deck building takes time and needs expertise.

Solution

You choose the strategy, archetypes and core cards, and an agent helps you build a balanced deck.

Outcome

An easy and pleasant user experience to go quickly from a deck idea to a full PDF printout so that I can try different strategies with my kids.

#Portfolio#Open Source

Personal portfolio site

Why I built it

I wanted to create a personal page about myself in an authentic way, showing both my professional and personal passions. It had to be unique and stand out in a sea of always the same portfolio pages.

The vision

Visitors should be able to learn about me, follow my content, getting interested and contact me.

The journey

A vertical scroll journey through atmosphere, time, and depth. Scroll drives the day to dusk to night transition, the sun arc setting and the moon arc rising. Sidetracks are the depth surface: a card dives into a floating panel while the landscape stays visible around it. The column is the site's own minimap, frozen, drawn from the same sky curve you are scrolling through right now.
