ABOUT ME

I am a Full-Stack Developer with strong expertise in both frontend and backend development, focused on building scalable, secure, and high-performance web applications. My experience spans designing clean user experiences on the client and architecting robust backend systems on the server. I work across the stack with React, Next.js, Node.js, Express.js, and TypeScript, utilizing databases like MongoDB and MySQL.

To ensure performance and reliability, I implement microservices, caching, session stores with Redis, and message queues. I leverage WebSockets for real-time capabilities and deploy applications using Docker, AWS, and automated CI/CD pipelines. Additionally, I integrate AI capabilities, automation tools, and modern developer tools to solve real-world problems with clean, maintainable code. My goal is to build reliable products that deliver excellent user experiences and scale seamlessly as they grow.
