About

As a Software Engineer with 5+ years of experience, I specialize in building scalable, secure, and high-performance backend systems using JavaScript, TypeScript, Node.js, and AWS serverless technologies. I have a strong background in architecting microservices and serverless applications, with hands-on experience in designing real-time systems using WebSocket, Redis, and messaging services like SQS. I enjoy solving system design challenges and working with cross-functional teams to turn product ideas into robust and maintainable code. I'm always open to collaborating on impactful technical initiatives—whether it's backend architecture, performance optimization, or setting up efficient CI/CD pipelines. I bring a product mindset, engineering discipline, and a passion for building solutions that scale.
