About

I build the backend that makes apps feel fast, reliable, and alive. Over the past 3 years, I've worked across the full stack — from designing Node.js APIs that handle 10,000+ concurrent WebSocket connections, to building React dashboards and Flutter mobile apps that real users depend on daily. I don't just write code that works. I write code that holds up when traffic spikes, data scales, and deadlines don't move. At Gen Alpha Digital, I architected the backend for Roomigo — a flatmates platform where real-time chat, AI-powered document verification, and role-based access all had to work seamlessly together. I cut token validation time by 40% using JWT + Redis caching, and reduced manual onboarding effort by 80% with a Python + OCR pipeline. At Ebani Tech, I built a CRM handling 150,000+ customer records across 10+ branches — and brought query latency down by 35% through indexing and schema redesign. What I'm good at: → Node.js, Express.js, REST APIs, WebSockets, Socket.io → React.js, Flutter, HTML5, CSS3 → PostgreSQL, MySQL, MongoDB, Redis, BullMQ → AWS, Docker, CI/CD, JWT, Zod, Sequelize ORM → System design, Agile, and writing code other developers actually enjoy reading I care about building things that scale — not just things that ship. Right now I'm looking for a Node Js Developer role where I can own meaningful backend challenges, work with a sharp team, and build products that genuinely matter to the people using them.
