About

Backend Developer specializing in Node.js, TypeScript, and relational databases, with experience building scalable APIs, async job processing, and production-ready systems. I have worked on task management, billing, and ATS platforms, focusing on performance, reliability, and security (JWT, RBAC, audit logging). I’m comfortable owning backend services end to end from database design and REST APIs to Docker-based deployment and VPS management and I also have hands-on experience with WordPress and basic React, HTML, CSS for web workflows.
