What I'm looking for

I’m looking for a role where I can build secure, reliable enterprise features end-to-end—backend and frontend—using Node.js, React, and strong API practices, while improving performance and resilience with real-world workflow modules.

I’m a Software Engineer experienced in Node.js, React, and TypeScript, focused on shipping backend and frontend functionality for enterprise applications. I’ve worked across authentication, validation, REST API consumption, integration, state management, and data persistence.

In my recent work at MVPX AI, I architected a multi-tenant Node.js backend with automated testing (Node Native Test Runner) and implemented safeguards to prevent inventory race conditions, reducing concurrency failures by 40%. I also improved user experience for asynchronous states—loading, empty states, and error boundaries—so critical POS modules feel more stable.

I’ve built secure authentication flows for pawnshop operations (OTP and account recovery) and reduced onboarding friction by 20%. By migrating state management to Zustand and server caching to React Query, I cut redundant REST API calls by 35% and improved data consistency across screens.
