What I'm looking for

I am looking for a role that challenges me and fosters growth in innovative environments.

I am a dedicated Software Development Engineer with a strong background in designing and delivering high-performance back-end systems. My journey began at PES University, where I earned my Bachelor of Technology in Computer Science with a GPA of 8.65. Since then, I have honed my skills at Games24x7, where I was promoted within two years due to my exceptional performance and leadership in critical projects.

At Games24x7, I have successfully owned the design and delivery of microservices and event-driven pipelines that handle up to 150K transactions per second. My work with technologies such as Kafka, Spark, AWS Lambda, and AWS DynamoDB has significantly improved system reliability and reduced latency. Additionally, I have a proven track record of migrating large datasets and developing robust Java/Spring Boot microservices that maintain a 99.9% uptime.

Beyond my professional experience, I have contributed to various projects, including a CI/CD framework and a replication of the raft consensus algorithm in Rust. I am passionate about leveraging technology to solve complex problems and continuously seek opportunities to grow and innovate in the software development field.
