My Experience

Software Developer in Test

Global Relay (Vancouver, Canada) | Jan 2024 - April 2024

  • Implemented 50+ test suites using the .NET Framework to evaluate microservices, ensuring comprehensive stability and full test coverage across services.
  • Tested the BFF (Backend for Frontend) using Jest to validate reliable responses and smooth interaction between frontend and backend systems.
  • Utilized LINQ and MockServer to create mocked API responses, enabling isolated and efficient testing of individual components without live service dependencies.
  • Employed a test-driven development approach by creating dedicated Git branches for each feature ticket, writing tests, and triggering a Jenkins build to ensure tests passed before integration.
  • Developed and executed regression tests to verify the stability of new features and prevent regressions in critical microservices.
  • Refactored tests to optimize execution time, improving efficiency across all test suites and accelerating feedback cycles.
  • Collaborated with cross-functional teams, integrating new features and resolving issues to optimize product workflows.

Backend Software Developer

Cendamte (Vancouver, Canada) | Jan 2023 - Dec 2023

  • Ensured accurate and reliable data retrieval by validating API request responses and processing the data for downstream use.
  • Developed and maintained 10+ API endpoints using Python (Flask) and Java (Spring Boot), optimizing performance and ensuring seamless communication between internal systems and external bank APIs.
  • Integrated backend services with the BFF (Backend for Frontend) to enable real-time data transmission to the frontend, ensuring the accuracy and efficiency of client-facing data.
  • Stored and managed validated API responses in MSSQL, ensuring robust data storage, efficient retrieval, and high database performance.
  • Conducted rigorous unit and API tests, ensuring robust backend functionality and reliability in the production environment.
  • Automated deployment workflows using Jenkins for continuous integration and ensured smooth delivery pipelines for new code updates.
