Full-stack engineer specializing in production LLM systems, looking for part-time contract work (~20 hrs/week). Recent shipped work: an AI agent over a steel-trading company's ERP — RAG + tool-calling into live SQL via a custom TypeScript MCP server, structured outputs with eval/failure handling, used daily by operations staff. Also Rankoo, a multi-tenant SEO automation SaaS (Fastify + Postgres/Prisma, BullMQ/Playwright workers, Claude API with prompt caching), and NavliQ, a deployed NestJS freight marketplace (public code: github.com/denizcakiroglu322/navliq-backend).
I judge well on what to hand an LLM vs. what to keep deterministic. Happy to do paid trial tasks — I'd rather be evaluated on work than CV.
