What I'm looking for

I'm looking to lead high-impact full-stack, AI, and cloud platform work, taking ambiguous requirements through architecture, delivery, and reliable production outcomes while mentoring teams. I'm open to relocating to the Netherlands.

At Persistent Systems, I lead architecture and delivery for LLM-powered features, a Python AI research agent, and a Kafka-based WhatsApp Business chatbot platform that scales to 1,000 users per second on AWS.

I reduced audit time by 60%, cut new-developer onboarding time by 80% with a developer-facing design system and Sitecore XMC APIs, and delivered a zero-downtime Next.js, GraphQL, and Sitecore XMC migration that improved page load time by 55%.

Previously at GoTo Technologies, I built React, Python, and Django tools that cut analyst research and documentation time by 82%, while improving performance, accessibility, testing, and consistency across enterprise products.

I bring 10+ years across SaaS and ecommerce, from National/Enterprise Car Rentals platforms serving 14M+ monthly visits to full-stack systems built with React, TypeScript, Node.js, Python, PostgreSQL, and AWS. I enjoy taking ambiguous requirements through API design, testing, deployment, code review, and mentoring.
