What I'm looking for

I’m looking to lead GenAI/agentic platform delivery that’s secure and compliant—turning strategy into production systems, scaling multi-team execution, and improving cost, reliability, and developer productivity through measurable outcomes.

I’m a GenAI Engineering Manager and engineering leader with 15+ years of experience building and scaling platforms for payments, e-commerce, and financial products across user bases up to 70 million. I align technical strategy, architecture, and delivery with business outcomes, including GMV growth, customer engagement, infrastructure cost, reliability, and regulatory posture in fintech.

In my current role, I established a Generative AI Engineering organization from a stalled, zero-delivery state into a high-output team in 6 months—shipping 5 production systems and driving a 12% CSAT uplift. I architected a RAG-based AI support chatbot that reduced resolution time by 70%, deflected 90% of Tier-1 queries, and replaced a third-party solution to eliminate ~$400K in annual vendor costs.

I’ve also led platform transformation as a Director of Engineering, including building an end-to-end eCommerce platform and implementing a fully automated CCPA compliance pipeline that reduced manual effort by 1,500+ hours annually and saved $100,000+ per year.
