Work Experience

Software Development Intern · Dicotr

Aug 2025 — Nov 2025
  • Designed and implemented MySQL database schemas and optimized queries for core application data, supporting CRUD operations across 4 microservices and eliminating data sync inconsistencies.
  • Built JWT-based authentication and route-level authorization middleware in Node.js/Express.js, securing access across multiple API endpoints.
  • Designed and deployed RESTful APIs in Node.js/Express.js, handling routing, request validation, and error handling for core backend services.
  • Debugged critical data inconsistency issues in production by tracing query and API logic, improving end-to-end reliability for live users.
  • Collaborated in an Agile team environment using Git-based workflows, code reviews, and iterative sprints.
