I bring 20 years of uninterrupted production ownership across Linux infrastructure, search-engine backends, ecommerce platforms, and AI infrastructure. I’m at my best when senior execution is required from week one, especially in founding, AI infrastructure, or forward-deployed roles.

I’ve built and shipped event-driven AWS systems—SQS FIFO, Lambda, DynamoDB, Step Functions—alongside LLM pipelines, RAG architectures, and multimodal AI stacks. I deliver these without a PM layer, with full deployment accountability, and I thrive as the technical layer between product and client during major internet-architecture shifts.

In my long-term client engagement, I’ve migrated an order pipeline to AWS-native architecture using API Gateway, SQS FIFO, Lambda, DynamoDB, and Secrets Manager. I designed for idempotent webhook ingestion, built webhook-driven automation with Step Functions, and delivered real-time AI-assisted workflows with FastAPI SSE streaming, including a RAG chatbot powered by Supabase auto-embedding and Cloudflare Workers AI.

Recently, I joined an AI platform that had stalled and shipped production v1 in one week. I architected the full AI stack with a React/Vite frontend, Supabase backend with auto-embedding, FastAPI microservices, and multimodal agent pipelines—then owned DevOps with CI/CD, reverse proxy, RLS-secured migrations, and CDN-optimized media pipelines.
