Need a system built, a website maintained, or a hand with a deployment? Send a message — and if I’m not the right fit, I’ll point you to someone who is.
Multiplatform invoicing that respects your data. Local-first, fully encrypted, and synced for free over Proton Drive with on-device encryption. It sends invoice emails straight from the app — automatically tailored to each customer — and ships with a proper terminal version for the geeks alongside the Android app.
A site builder where the wizard does the thinking. Answer a handful of questions and it assembles a finished, personal page for you — the guided flow is the whole point, turning “I wouldn’t know where to start” into a live site in minutes.
A booking platform run entirely from your phone, with a clean public calendar. Customers top up a credit balance with cash or crypto — so there are zero card-processor fees — and the whole thing is built on a simple principle: data that never exists is the only data that can never leak.
I like the projects people warn me about — the ones that “might fail” or sit right on the edge of what’s possible. Hard problems need the right mix: technical depth, real business understanding, and enough emotional intelligence to know what people actually need.
Contracting for Starhunter GmbH, building custom software and systems. Alongside it I develop my own products — TidyBill and CYP — take on client work like a privacy-first booking platform, and help non-technical people with the web and crypto.
ERP & CRM systems built on open-source EspoCRM in a startup-mentality environment — developing custom and general extensions, leading projects, and working directly with customers on features, deadlines, untangling problems, and healing miscommunication.
Virtualization and the libvirt library — fixing bugs and adding features in C and Rust. libvirt commits →
Thesis: plant disease recognition using artificial intelligence.
I’m equally happy translating between a business team and an engineering team, or sitting with someone who’s never touched a terminal and helping them feel in control.
I’ve worked in systems programming — through university and an internship at Red Hat — and building the software companies run on: CRMs, ERPs, HR tools. Along the way I got just as interested in the opposite end: small, honest apps that protect the people using them. Local-first, encrypted, no data hoarding.
Away from the screen, I love travelling and discovering new places — always chasing new challenges and knowledge wherever they are.
The stranger the problem, the more interested I am. Send what you’ve got — even half-formed — and I’ll tell you honestly whether I can help.
