Automation & Integrations Engineer — Berlin
I turn manual operations into reliable, traceable systems. I work across n8n, Make, Python, APIs, accounting workflows, and developer tools.
Selected proof
- Portfolio case studies — fail-closed accounting, invoice pipelines, 50k+ intake automation
- hamberger-dl — supplier-document CLI with OIDC and safe re-runs
- Merged iii contribution #690 — Rust streaming LLM provider worker
- python-escpos-cli-skill — printer CLI skill verified on Epson TM-m30II
- Workflow automation and API integrations that survive retries, audits, and handoffs
- Accounting and document pipelines — SumUp → Lexware, supplier PDFs → Lexware, payout evidence
- Intake and guidance systems — JurisDATA case study that helped 50,000+ people
- CLI tools and backend services — Python, FastAPI, PostgreSQL, Docker
Peer-to-peer systems training at 42 Berlin — C/C++, Unix, networking, concurrency, Docker, infrastructure. Helps me read both sides of an integration when it breaks in the middle.
