Senior🎓
Top SchoolViacheslav Ptsarev is a Senior Software Engineer with 13 years of experience building high-load, distributed systems and a recent focus on shipping production-grade GenAI and LLM-powered features. He designs document-based chatbots, internal knowledge assistants, and resilient AI components with clear contracts, observability, and predictable behavior, bridging MVP iteration to scaled deployments. Hands-on at heart, he has led cross-functional teams and driven technical strategy while implementing practical engineering solutions such as Qdrant vector search, LangChain/LangGraph orchestration, and Stripe migrations that cut acquiring costs by 40%+. His work on AI document understanding pipelines (OCR, semantic classification, PII scrubbing) reduced manual processing and improved NPS, reflecting a pragmatic mix of product focus and reliability engineering. Based in Valencia, he combines deep Ruby/Go experience with cloud-native practices to make GenAI a first-class system capability rather than an experiment.
