About Timofey
Full-stack engineer with 4 years taking loosely-defined product ideas to live, scalable systems for founders and enterprise clients — across AI/LLM systems, low-code product builds, and event-driven automation.
I own the full cycle: requirements, data model, UI, workflows, payments, AI layers, and post-launch monitoring.
I architect multi-tenant SaaS with data isolation and RBAC, build multi-step RAG and agent pipelines with custom evaluation harnesses, orchestrate automation in n8n, integrate Stripe and third-party APIs, and drop into Python/JavaScript where low-code falls short.
Shipped 8+ live systems, including a multi-tenant B2B platform serving 27+ enterprise accounts and a multi-step RAG agent (30,000+ indexed items).
