Back to original languageAbout Roman
Staff backend, 13 years of experience, freelance. I help tech teams move their GenAI/LLM features from POC to production, without degrading code quality. Full remote from Dordogne, max 1 on-site visit per month.
The proof is public and reproducible:
‣ mcp-auditor: agentic security testing of MCP servers, delivered as a PyPI package. Multi-graph hexagonal architecture, calibrated LLM-as-a-judge, evaluation harness in CI, reproducible metrics in the repo.
‣ A production-ready RAG repo under construction: golden set, retrieval and generation evals, observability.
Beyond GenAI:
‣ Architecture & software design: Domain-Driven Design (strategic and tactical), hexagonal architecture, refactoring of mature codebases.
‣ Distributed systems & data: event-driven architectures (Kafka), Medallion pattern, large-scale ingestion.
‣ Engineering culture: trunk-based development, TDD, continuous delivery. I founded and co-led an internal guild "Augmented Engineering", and led over 40 technical workshops.
In 4 years at a B2B SaaS scale-up, I delivered 2 GenAI systems in production and continuously transformed the codebase (CD, hexagonal, DDD).
In-depth reading notes in software engineering accessible from my GitHub.
