Senior backend engineer and tech lead (9+ years) with a production PHP/Laravel/PostgreSQL foundation, now leading AI/agent-systems work: RAG pipelines, custom MCP servers, and multi-agent orchestration. I own systems end-to-end — architecture, delivery, infrastructure, and the AI layer on top — and run a self-hosted stack as an ongoing engineering practice, not just a résumé line.
Led a 5-person team (2 dev, 2 QA, 1 PM). Multi-agent orchestration building a per-student knowledge map that continuously replans the curriculum. RAG + OpenAI embeddings over a MongoDB vector store, LangChain. 1,000–10,000 students; strong weekly retention (5–7+ return visits).
Led a 3-person team. Continuously ingests, catalogs and indexes gigabytes of document batches with background processing that keeps the server responsive. Cut document search from days to minutes; encrypted APIs for client-data security.
A full editorial + technical fact-check pass across 31 modules of two production Ukrainian courses, using an LLM as the primary QA/rewrite engine. Findings logged across 4 structured documents (an auditable trail), catching version-specific inaccuracies a single manual pass would miss — the same rigor as the legal-firm document engagement, applied to instructional content.
