Technical Product Leadership

Scrum Product Owner Certified

We prioritize the roadmap, scope requirements, write specs and coordinate stakeholders. Two startups cofounded and run end-to-end (Foundingbird, Kaunto): we know what shipping looks like.

AI for Business

We help SMBs and enterprises adopt AI: RAG, semantic search, LLM integrations, workflow automation, finding the right tool without overengineering. Designed and sold a Document AI SaaS in 2025.

Solutions Architecture

Built the ingestion pipeline for 100M+ pages at L'Oréal (OCR, vectorization, semantic search). Designed relevanC's analytics platform processing 400M+ events/month.
Full-stack (React, React Native, TypeScript, Python, FastAPI) on GCP with Terraform.
