I’m a Software Development Engineer Intern who designs and optimizes production-ready backend systems, especially REST APIs for business-critical workflows. At SyneGrow, I reduced API response time by 25% through query optimization, indexing, and efficient data handling, while improving reliability by handling failed transactions, retries, and data consistency across edge cases.

I also build end-to-end features and interactive user experiences, translating backend performance improvements into measurable outcomes. In recent projects like a Finance Dashboard and Split-Wise, I implemented scalable data models, JWT-authenticated REST APIs, aggregation pipelines, and dashboards—improving performance by up to 40% and delivering analytics that users can act on.
