About

I'm a senior software engineer and manager with 12+ years across design, development, release and architecture — lately focused on integrating AI-powered workflows into production systems: LLM agents, RAG pipelines on Qdrant, tool use, MCP servers and cost-aware prompt engineering.

I've led cross-functional, multinational teams end to end — from pre-sales and estimation to backlog ownership, release planning and delivery. PSM certified.

Beyond software: vast experience in live, studio and programmatic audio, plus video recording, mixing and editing — which is exactly where the DMX Sandbox and the ADDA gallery come from.

Services

Remote-first, worldwide. From a focused consulting engagement to owning the full delivery.

Web & product development

End-to-end delivery of web products: architecture, React/TypeScript front-ends, Node.js back-ends, releases and everything between. The same practice that shipped for Nike, Mars, GAP and Wix — 30%+ faster load times, 2–3x faster builds.

AI integration

LLM agents, RAG pipelines, tool use and MCP servers — wired into real production systems, not demos. Recent work: 40% lower inference costs, sub-second retrieval over 500K+ embeddings, document pipelines cut from ~8s to under 2s.

Consulting & technical leadership

Architecture reviews, project rescue, pre-sales and estimation, roadmaps and risk management. I've led cross-functional multinational teams end to end and secured $1M+ in contract extensions doing it. PSM certified.

Experience

Oct 2025 — present

Staff Full Stack AI Developer / Product Owner

NDA

Designed and built a modular AI processing platform: ingestion of documents, images and audio, vector indexing on Qdrant, LLM extraction and multi-step agent workflows (Anthropic SDK), GPU-accelerated processing. Cut LLM inference costs 40%, achieved sub-second retrieval over 500K+ embeddings, and brought document pipeline latency from ~8s to under 2s.
