Work
Five projects, written up properly: the problem, what I built, how it fits together and what came out. Most of the code is private because it belongs to a client. One repository is public.
- NEXOOne ERP where there used to be nine separate apps. A food distribution company in Lima runs sales, stock, finance, HR, production and deliveries in it.ERP
- AI customer serviceOne assistant, built for WhatsApp, Messenger and Instagram, that knows whether it is talking to a consumer or a business and answers from the company's own documents.n8n, RAG
- Delivery systemThe day's orders go in as a spreadsheet. Out come routes per zone, a phone app for drivers that works without signal, and a settlement per zone at the end of the day.Logistics, PWA
- n8n workflow examplesFour workflows you can read, import and run. Built for a made-up coffee roaster, tested, and published with the tests.Open source
- JACKMy own voice assistant. It listens on my laptop, thinks with Claude, talks back, and can read my calendar, my messages and my servers.Own project
Smaller things, same habits
- Cash book
- Replaced a hand-kept Excel cash book: bookings that cannot be edited afterwards, a balance check per bank, corrections that need approval. Now the finance module of NEXO.
- Biometric attendance
- Clock in with a fingerprint or a face, only inside a set distance from the workplace. First version live in April 2026, now a module of NEXO. About 300 clock-ins a day without paper or spreadsheets (estimated: 75 staff, 4 moments a day).
- Invoice bot
- On the 5th of every month it collects last month's AI invoices from two mailboxes, converts the amounts and mails them out with the PDFs. Live since September 2026.
- Server monitoring
- An agent that runs health checks and may restart a service by itself, with a circuit breaker and a log that cannot be edited. A prototype that ran on my own production server.
Tell me what goes wrong on a normal Tuesday.
Thirty minutes, video or phone. You describe one process that costs you time. I ask questions and tell you honestly whether I would automate it, fix it first, or leave it alone. No slides.
Lima time, UTC-5. I reply within one working day, in English, Dutch or Spanish.
Open to remote roles and to projects.
