I am a Senior Full-Stack Software Engineer with over 7 years of experience building scalable, production-grade systems. I specialize in architecting modern web applications using React, Node.js, and AWS, with a strong focus on distributed systems, performance optimization, and secure cloud-native infrastructure.
I have designed microservices architectures, built high-traffic APIs, implemented DevSecOps-driven CI/CD pipelines, and optimized both SQL and NoSQL databases for reliability and speed. My approach goes beyond feature delivery — I build systems that are secure, maintainable, and engineered to scale.
I take ownership across the full lifecycle, from architecture and development to deployment and operational stability. I value clean design, automation, and long-term engineering excellence.
I design and lead the development of production-grade systems used in real-world environments.
From architecture and microservices to cloud infrastructure and CI/CD, I build software engineered for reliability, performance, and long-term scale.
