Andrey S.
Staff Engineer | AI Integration, Automation, MCP | 16+ yrs backend
I build MCP servers and agentic AI workflows that run in production. Right now: an ongoing AI-integration engagement (Proposal Technologies, since 2024), plus an MCP server fleet, a code-execution sandbox and multi-agent orchestration I run daily to keep coding agents working across several workstreams at once, with tight control over token cost. Earlier: a 2020–2024 engagement on a meeting-intelligence SaaS — conversation analytics from 2022, then generative LLM features live in production from mid-2023 on the OpenAI API, earlier than Zoom AI Companion (Sep 2023) and Google Meet's AI: call-transcript summaries, speaker diarization and per-participant notes flowing straight into the customer's CRM. Underneath: 16+ years of backend engineering in PHP/Symfony — high-traffic services, legacy modernization, payment integrations, REST/OpenAPI, MySQL/Postgres/Redis/Elasticsearch, AWS, Docker. I take on selective senior engagements where deep backend experience and modern AI integration both matter. Available 30+ h/week.
