Senior Product Manager · AI products · Builder-PM
I build AI products and write the code alongside engineering, so what I spec is what ships.
Most of my work is hands-on: agents that hold memory across sessions, retrieval over data that can't leave the building, and verifiers that catch a model being confidently wrong. I maintain Holt, an open-source local-first personal AI OS.
What I work on
- AI agents: multi-agent orchestration, tool calling, MCP servers, background and scheduled agents
- Memory: vector recall, distilled facts, knowledge graphs over code and notes
- Retrieval: local embeddings, self-hosted vector stores, RAG for regulated data that can't hit a cloud API
- Evals: deterministic verifiers and faithfulness checks. "Looks right" isn't a metric.
- Local-first LLMs: Ollama and on-device inference under real memory limits
- Generation pipelines: voice cloning and programmatic video, script to render, unattended
- Product: 0 to 1 AI features in fintech, across insurance, payments, and a Microsoft Copilot embed

About me
10 years in product. Senior Principal PM at MoneyLion (acquired by Gen Digital), running a $9.6M ARR business unit and shipping the Microsoft Copilot embed beta. Before that I founded CoolHax Labs and shipped 100+ products, and earlier built Vehicle Score at Exelinserv (15K+ customers) and Share-D, Odisha's first co-working space. Computer science engineering degree, and I still write code most days.
Working with me
Running AI agents across a team and need memory you can audit? I'm taking Holt Teams design partners. Hiring an AI PM in the EU? I'm in India, relocating to the Netherlands, HSM-eligible. Training an engineering team on agent workflows? I run hands-on programmes for teams and universities.
