What I'm looking for

I’m seeking backend or full-stack engineering roles where I can design scalable services, improve integrations, and deliver measurable product and operational impact in collaborative, growth-oriented teams.

I am a senior backend software engineer focused on designing scalable microservices, building secure webhook integrations, and integrating external APIs to improve reliability and reduce defects. I have delivered data-heavy admin dashboards and frontend improvements that cut operational effort and task completion time substantially.

Previously, I built full-stack MERN applications, developed performant API endpoints, and created multilingual email templates to boost user engagement. I combine strong backend expertise with frontend and DevOps tooling to drive measurable impact in remote engineering teams.
