Leveraging Java and its framework Spring Boot, I automated data import functionality, enabling bulk record uploads and streamlining data validation processes. This improved data entry efficiency by 50%, significantly reducing manual errors. I was involved in both API design and optimization, where I developed over 10 APIs from scratch and optimized 15+ existing ones, many of which involved multithreading for high performance.I worked extensively with relational databases, creating and optimizing tables with indexing strategies that enhanced query performance. My work played a crucial role in ensuring that the data pipeline efficiently supported the company’s core business operations, including route planner execution and asset management. This involved collaborating with cross-functional teams to ensure data accuracy and integrity, as well as contributing to the company’s broader data architecture built on microservices, designed to optimize route planning and execution using various algorithms.My role required a deep understanding of data handling, database optimization, and applying software engineering principles to real-world problems, along with the requirements for data science and engineering roles.
