TankBilligt
ProductionDenmark's cheapest-fuel app — 2,000+ users. iOS + Android + a Node/TS backend with server-side IAP validation and cron price-scraping.
Bioinformatics engineer and full-stack builder at Aarhus University. Native iOS and Android apps, production backends, ML/CV pipelines, offline LLM systems and HPC bioinformatics — designed, built and operated end to end.
How a lab manager ended up writing production software.
I came to software from the bench. I set up Oxford Nanopore sequencing in-house, prepared and multiplexed libraries for Illumina and Nanopore, and built the 16S, RNA-seq and metagenomics workflows that processed what came off them and somewhere in there I became the person who also built the tools. Today I run daily operations for a molecular biology section at Aarhus University, coordinate an international research consortium, and keep building.
The hard part of writing software for a laboratory is rarely the code. It is that the code has to be right about something biological it does not understand.
That is the thread through everything below. Most developers can build the system; fewer can read the data running through it. I have spent years on both sides of that line, which is why the lab’s ordering and sample database, an offline assistant my colleagues use daily, and a phenotyping pipeline that cleared months of manual measurement all look like the same job to me.

Danish citizenship exam prep on iOS, Android and web — the web flow takes real money through Stripe, with the receipt, right-of-withdrawal and terms pages Danish consumer law requires.
Danish flashcards with a Leitner spaced-repetition engine, lock-screen widget, and zero external dependencies. Live on iOS; the Android build is unreleased.
Lab calculators and protocol timers with Lock Screen Live Activities and iCloud sync, for bench scientists. Live on iOS; Android in development.
On-prem LLMs, local-first pipelines, autonomous agents — and the tooling around them.
A fully offline RAG assistant over lab protocols and safety documents — no cloud LLM ever sees the data. It cites a source on every answer, and says a protocol is not in the indexed set rather than inventing one.
A photographer's cull-to-stock automation: RAW culling, a three-axis local-AI scorer, and multi-agency submission.
View overview →Tooling for the coding agents themselves. It reads Claude Code’s own session transcripts and builds one local page of every command the agent ran — grouped by day, mapped to the repository it ran in, with the output it printed and a search that covers that output. No hook, no daemon, no dependencies, and it never writes to the agent’s own files.
Read the code ↗Autonomous social-content pipeline designed to give retired hardware new life — data → generation → media → posting.
View overview →HPC pipelines and rigorous, reproducible analysis.
Turns a consumer DNA download (MyHeritage, FTDNA, 23andMe, AncestryDNA) into a readable, honest report — ancestry, drug response, HLA type, polygenic scores and ClinVar variants — without the genome ever leaving your machine. On the NA12878 reference sample, its HLA calls match the published typing at 10 of 10 alleles and its drug-gene calls exactly match the CDC GeT-RM consensus for 10 of 12 genes, with the other two agreeing in part.
A CV pipeline turning messy lab photos into publication-grade plant phenotype data with YOLOv8/11 + geometry.

A laboratory information system for a 4-node genome-editing facility. Ordering, oligos and personnel/permissions are built; consolidating four standalone databases into one is roughly half done.
