Over mij
I build custom web apps, CRMs and automations that fit the way your business actually works, from requirements and code to testing and launch. I connect the tools you already use via APIs, cut manual data entry and streamline order handling. Where documents or text need interpreting, I use AI. Recent work: a full CRM linking sales, stock, quotes and invoicing; a 3D PV roof-tile configurator; competitor price monitoring; automated online store audits. Stack: TypeScript, React, Next.js, Node.js, Python, FastAPI, Django, SQL, Docker. Scope and price are agreed before work starts.
