Hi, I'm Ergini.
I work alone, on purpose. No account managers and no handoffs: the person on your first call writes the code.
For more than five years I've shipped production software, lately mostly AI.
TypeScript · Next.js · React · Node.js · Python · OpenAI · Anthropic Claude · Vercel AI SDK · MCP · Postgres · pgvector · Supabase · n8n
Working with teams across Europe and North America.
A direct contract, with calls set around your working day.

With me, Ergini, an independent AI engineer and software developer. I scope, build and ship every project myself, with no agency layer and no junior handoff. The person on your first call writes your code.
AI agents, AI integrations, workflow automation, and web apps and MVPs built with Next.js, TypeScript and Postgres, on OpenAI, Anthropic Claude or open-source models.
AI integrations usually run $3.5K to $45K, AI workflow automation $3.5K to $60K, AI agents $12K to $60K and MVPs $5K to $60K. Ongoing work runs on an hourly retainer, quoted on request. Your quote is set after a free 30-minute call.
A single AI feature takes 1 to 3 weeks, agents and automations 2 to 8 weeks, and an MVP 6 to 10 weeks. You see a working demo every week.
Teams across Europe, including Germany, the United Kingdom, the Netherlands, Switzerland, the Nordics, France and Austria, as well as the US and Canada. All of it remote.
An independent engineer. I write the code on every project myself, on a direct contract.
Yes, on the engineering side: EU data residency where you need it, data minimization, a deletion path that reaches your vector store, and the logging and human oversight the EU AI Act asks for.
