Senior full-stack engineer with 21 years in production systems, working fractionally at ~10-20 hours a week.
Backend: Python (Django, FastAPI), Node.js, Go - API design, service decomposition. Data: PostgreSQL as the default, ClickHouse for analytics, ETL pipelines, BI, query performance tuning. Full-stack: TypeScript, Next.js, React, Tailwind. Infra: Docker/Compose, Cloudflare, CI/CD, Linux, monitoring. AI, applied: RAG, agents, MCP servers, and an AI-accelerated development workflow used on real systems, not demos.
Recent work: built and operate a marketing-analytics warehouse - ETL from 5 ad networks plus an affiliate tracker, PostgreSQL to ClickHouse, surfaced through a Django reporting UI and Metabase, with multi-currency normalization. Designed a multi-tenant SaaS architecture: isolated per-brand services plus separate admin and payment services, containerized end to end. Rebuilt a legacy regulated real-money transactional platform onto a modern stack in about four months, incrementally, preserving business logic. Build AI tooling - an LLM-managed knowledge wiki, a multi-agent consensus app, MCP servers.
Remote, strong European (CET) overlap.
