About

I am a software engineer with 4 years of experience as a Full Stack Developer. I focus on purposeful development, creating value, and finding ways to make a positive impact on the business. If this resonates with you, I’d love to connect and explore how we can collaborate to help your business grow. In my career, I have worked with a variety of programming languages, libraries, frameworks, and cloud providers, including Node.js, Python, JS/TS, Golang , Rust, React, Kafka, Kubernetes, GCP, and AWS. I was always fascinated by how companies like Google, Facebook, and Netflix designed their systems to handle huge amount of traffic while maintaining performance and reliability. This curiosity led me to explore distributed systems, and for my Final Year Project, I decided to build a microservices-based video streaming application inspired by Netflix, using AWS Lambda, and AWS API Gateway. Since then, I have worked with lots of distributed systems, which has deepened my understanding of their strengths and weaknesses. My interests span distributed systems, big data, AI, and MLOps. I am always eager to explore new technologies and understand their advantages and limitations.
