What I'm looking for

I'm looking to build and own production backend, data, and AI/LLM systems end to end, especially services involving integrations, RAG, real-time data, and reliable platform operations.

I've built production Python services, data pipelines, and AI workflows for reLove/Oracul, Beeline, Sberbank, and banking products. At reLove/Oracul, I built RAG pipelines and a FastAPI backend for a personal diagnostics platform serving 10K+ users and processing 64K+ messages.

I integrate OpenAI, Anthropic Claude, and Gemini through provider-agnostic services, and build multimodal processing for text, voice, and images. My work has automated analyst workflows by roughly 80%, delivered NLP extraction at 95% accuracy, and supported telecom platform modules operating at 1M+ RPS.

I’m comfortable owning services end to end: architecture, integrations, testing, Dockerized deployment, and production operations. I also build real-time collection and SSE streaming systems, REST APIs, and resilient integrations across REST, OAuth, webhooks, SOAP, sFTP, queues, and databases.
