Full-Stack Software Developer with 4+ years of hands-on experience (since March 2022) building high-performance, scalable web applications using modern JavaScript frameworks. Specialized in React.js and Vue.js, with expertise in Node.js backend development and growing proficiency in Rust for systems programming.
Currently working at Chandaria Industries Limited as an MIS Assistant & Software Developer, where I architect and deploy enterprise-grade applications serving 100+ users. In just 7 months, I've built two major production systems: a GatePass Management System (Vue.js 3 + React Native) and a Papermill Reel Tracking System (React + Socket.IO).
I'm passionate about clean code architecture, responsive design, and creating intuitive user experiences that drive business impact. Proven track record delivering projects in fully remote, asynchronous environments with international clients.
Key Strengths: React.js • Vue.js 3 • Node.js • TypeScript • REST/gRPC APIs • PostgreSQL • Responsive Design • CI/CD • Remote Collaboration
