Roman Marchenko

Senior full-stack engineering role building AI / LLM products and platforms: React/Next.js and TypeScript on the frontend, Node.js and Python (FastAPI) services behind it. Remote in Canada, or hybrid in Metro Vancouver. Most interested in LLMOps, model deployment UX, agent tooling and developer tools. At Alfa Bank, I build the internal AI platform through which the bank deploys, manages, and uses LLMs. My work spans the LLMStore deployment console, AIStore model marketplace, and AlfaGen, a bank-wide ChatGPT-class assistant. For LLMStore, I built Python microservices and the operations dashboard, including model discovery through Hugging Face APIs. In AIStore, I owned the product flow from UX to frontend delivery, so users can describe a task, get a model recommendation, and deploy it. I built AlfaGen’s chat UI and architected its Fastify and gRPC backend layer, integrating token streaming, file uploads, and prompt-driven workflows. I also built authentication flows for Alfa-ID, a consumer-scale SSO platform with 25M users and 6M+ daily authorizations. Previously, at Amur Financial Group, I established and led the web development department and migrated the company platform from WordPress to headless Next.js and Prismic. I also ship my own products, including React Native apps and a Swift IPTV player for iOS and tvOS.
