What I'm looking for

I'm looking to lead and build scalable full-stack products where I can modernize Rails systems, develop React experiences, solve high-concurrency challenges, and contribute to architecture, technical leadership, and reliable cloud delivery.

At Persistent Systems, I lead full-stack engineering for ezCater, modernizing order management, improving React-based UI performance, and building a dual-order write strategy that synchronizes legacy and new systems without downtime or data loss.

I've spent 12+ years delivering Rails and React applications across logistics, travel, e-commerce, healthcare, and enterprise platforms. At Thrillophilia, I designed an event-driven architecture for a platform serving 1M+ monthly users and solved surge-demand double-booking through Redis locks, PostgreSQL constraints, and pessimistic locking.

I also led six engineers at Island Traders Shop & Ship, where I built shipping, warehouse, pricing, and invoicing systems that reduced manual processing time by over 40% while maintaining 99.9% uptime on AWS. I enjoy building clean, testable systems with Ruby on Rails, React, event sourcing, CI/CD, and AI-assisted engineering tools.
