About

I'm a software engineer with over 4 years of experience building scalable backend systems and data pipelines using Java, Spring Boot, Apache Spark, and SQL. Most of my work has been around developing APIs, processing large volumes of data, and designing systems that are meant to last. Whether it's optimizing backend logic, tuning Spark jobs, or working with cloud services like AWS and Azure ... I enjoy solving real-world problems through clean and efficient code. I'm also certified in Databricks, AWS, and Azure. These certifications, along with hands-on project work, have shaped how I approach system design, reliability, and performance. Outside of work, I'm constantly exploring new tools, frameworks, and best practices... not just to stay updated, but to become better at what I do every day.
