About
I’m a backend-focused full stack developer who enjoys designing distributed systems and building reliable APIs that scale. I work with JavaScript and TypeScript to create secure authentication flows, async processing pipelines, and real-time features—especially with tools like JWT, Redis-based rate limiting, BullMQ, and Socket.io.
From an internal task management system to a multi-service API gateway with analytics dashboards, I like turning complex requirements into clean, maintainable services. I also value strong engineering fundamentals—type-safe TypeScript conversions, careful routing/reverse-proxy handling, and structured logging—so the products I build are not only functional, but easy to monitor and evolve.

Built a full-stack internal Task Management System to replace spreadsheet-based tracking. Developed RESTful API endpoints for task CRUD, user management, and role-based assignment using Mongoose. Implemented JWT authentication with bcrypt hashing and HTTP-only cookie sessions, supporting Admin, Manager, and Employee role flows. Contributed across Node.js/Express backend APIs and React frontend integration, focusing on secure access control and reliable data modeling for tasks and users.
