  • Developed and optimized robust back-end APIs using NestJS, leveraging its modular architecture for maintainable, scalable, and testable codebases. Designed and implemented microservice communication using Kafka, enabling real-time event-driven workflows between distributed systems.
  • Built custom middleware, interceptors, and guards in NestJS to enforce authentication, validation, and request lifecycle control. Integrated Prisma ORM for efficient database operations and implemented TypeScript decorators to enhance API maintainability and readability.
  • Configured database migrations from scratch to ensure consistency and reliability across multiple environments. Utilized Terraform for infrastructure as code, setting up Mailgun servers, DNS records, and automating deployment environments.
  • Migrated the entire project from Bitbucket to GitHub, restructuring from a monolithic single-repo into a clean multi-repo architecture aligned with service boundaries. Configured GitHub Actions for CI/CD, creating tailored deployment pipelines for each NestJS service and environment.
  • Managed end-to-end deployments using Google Cloud Platform (GCP) — including Cloud Run, Secret Manager, and Pub/Sub — to deliver seamless, secure, and auto-scaled back-end services.
  • Additionally contributed to the React Native iOS application, resolving bugs, refactoring legacy code, and adding new features such as a custom calendar component. Led the complete UI rebranding of the iOS app and handled TestFlight distribution for internal testing.
