Software Engineer 2 @NIQ | Python, Java, Spring Boot, React | Streamlining systems to cut processing time & infrastructure costs

About

Hi there! I'm Ashwin. I'm a software engineer with a strong foundation in backend development, currently working at NielsenIQ, where I’ve had the chance to redesign critical systems for performance and cost efficiency. My work involves everything from building microservices to creating internal tooling and optimizing data pipelines. Over the years, I’ve worked with technologies like Python, Java, Spring Boot, Bash, PostgreSQL, Oracle SQL, and REST APIs. Whether it’s scripting to automate regressions or architecting services to replace legacy tools, I enjoy solving real-world problems with clean, efficient code. I graduated in Computer Science from VIT in 2022, and since then, I’ve been steadily honing my backend skills—both at work and through side projects like full-stack platforms and social apps. I’m especially interested in scalable backend architectures, system performance, and developer productivity. Outside of work, I enjoy building things from scratch, experimenting with new tech stacks, and learning through code. I’m also big on sharing knowledge and helping others debug problems—something I got into naturally through mentoring juniors at my current role. I’m currently looking for opportunities in backend development, particularly in Python or Java-based ecosystems. If you're working on building fast, reliable, and secure systems—let's talk!
