Senior Python Backend · AI/LLM Integration
I untangle complex systems and ship them to production
Backend under load, LLM pipelines, legacy and migrations. No pretty wrapper over chaos.
Senior Python backend on long-term contracts — from spec to production. The four jobs clients come with.
FastAPI or Django from spec to deploy: caching, indexes, query optimization, CI/CD and documentation.
Legacy, technical debt, bottlenecks, migrations. I get into context, find the real problem, and bring it to a working state.
Bots, ETL, CRM and external API integrations, logging, internal platforms. Python, reliable, with support.
Prototypes, LLM pipelines, embeddings, AI-assisted development — where it delivers a result, not hype.
Two loops taken to production: product infrastructure and independent R&D.
Lead Python Backend / R&D · 2020–2025
Developed pvs-studio.com and ~20 related projects. SmartCache on Redis, 152-FZ web infrastructure compliance, a logging platform with a Python SDK, migrated the site from Python 3.9 to 3.13.
Independent / R&D · 2025 — present
Public EdTech MVP: FastAPI, async SQLAlchemy, PostgreSQL, JWT/OAuth, RBAC, rate limiting, AI content generation and mock interviews. Full stack from backend to Next.js.
A backend engineer with an R&D focus: I like problems where you have to understand a complex system, find the technical blocker, and take the solution to production. I work well with legacy, migrations, caching, integrations, and internal tooling.
I don't sell «magic AI» — I assemble managed loops: find the manual loop, pick a safe first step, build in checks. LLM tools speed up the work without replacing engineering responsibility.
Looking for long-term contracts: backend, R&D tooling, complex systems. Describe the task — I'll reply within 24 hours.
I write short engineering mini-books — no mysticism, no hype, about what actually changes the work.
How to spot the technological shift before the market and collect AI dividends
An expert mini-book for decision makers: where AI can already be built into the work, where it's still too early, and how not to buy a pretty imitation of transformation.

A practical mini-book for anyone who has seen the slow query log: why one index saves your evening, another changes nothing, and a third quietly chokes writes.
