About

Hi ✋, I’m a backend developer with 5+ years of experience building fast, scalable, and data-driven applications. I’ve designed and developed services handling millions of users, with expertise in multi-threading, concurrency, and object-oriented design. Proficient in Go, Java, Python, and C/C++. My professional journey has equipped me with hands-on experience across all stages of the software development lifecycle within an agile framework—right from planning and design to development, testing, and deployment. My strong foundation in programming fundamentals allows me to quickly adapt to new technologies, continuously expanding my skill set to stay at the forefront of innovation. In backend development, I’ve designed and implemented microservices, APIs, and distributed systems using technologies like Java and Spring Boot. On the data front, I’ve built ETL workflows and Change Data Capture (CDC) pipelines, leveraging tools such as Kafka, SQS to extract actionable insights, enhance system performance, and improve scalability. I’m passionate about solving complex problems, optimizing systems, and delivering impactful solutions. Let’s connect and explore how we can work together to build cutting-edge solutions that make a difference!
