What I'm looking for

I’m looking to lead end-to-end AI-enabled products: RAG/LLM systems with strong evaluation and grounding, while owning scalable full-stack architectures (NestJS/AWS/Postgres), prioritizing security, cost control, and measurable performance gains.

I’m an AI & full-stack engineering lead with 3+ years shipping production systems end to end. I built and owned a multi-tenant SaaS platform greenfield—from relational schema through serverless AWS infrastructure—and shipped a production RAG assistant over financial data.

At Accotech UK Ltd, I led greenfield stack selection, service architecture, and a tenant isolation model across NestJS, Supabase, and serverless AWS, working closely with the CEO, marketing team, and client firms. I delivered measurable wins like cutting Lambda spend 30% (AWS Lambda Power Tuning), reducing dashboard latency from 1,500ms to 300ms (rollups + Redis), and shipping a RAG assistant that grounds every answer in retrieved source documents so it declines rather than guesses.
