• UploadStream-gRPC

  14/12/25, 12:23

  GitHub repo

  Developed a production-ready file transfer service in Go, leveraging gRPC client/server streaming for efficient handling of large (multi-GB) files.

  Implemented chunked bidirectional streaming (64KB default) for memory-efficient transfers, supporting resumable uploads/downloads without loading entire files.

  Integrated PostgreSQL for ACID-compliant metadata storage (user ownership, pagination, soft-delete with deleted_at), filesystem abstraction for data, and proto-validate for input validation via Buf toolchain.

  Provided Kubernetes manifests for scalable deployment, incorporated Prometheus metrics/alerts (capable of 10k+ daily uploads), and added Makefile for build/test automation and migrations.

  Demonstrated modern Go practices (generics, gRPC ecosystem) and cloud-native best practices.

• RealTimeChat-gRPC

  14/11/25, 12:23

  GitHub repo

  Built a scalable, low-latency one-on-one chat service in Go using gRPC bidirectional streaming for persistent, real-time messaging.

  Designed MongoDB persistence layer with optimized indexes for efficient storage/retrieval, using modular repository pattern.

  Implemented gRPC interceptors/middleware for authentication, rate limiting, JWT secret rotation, and TLS/mTLS encryption; managed Protocol Buffers with Buf toolchain.

  Containerized with Docker Compose (including MongoDB orchestration) for seamless local/production deployment.

  Followed test-driven development with comprehensive unit/integration tests and GitHub Actions CI/CD.

• BMG-Go-Backend

  14/10/25, 12:23

  Github repo

  Developed robust RESTful API in Go powering a React Native inventory app, handling authentication, item management, file uploads, and 20k+ daily operations.

  Designed clean layered architecture (handlers, services, repositories, domain) with dependency injection and lightweight HTTP routing.

  Integrated PostgreSQL (via sqlx) with repository pattern and automated migrations for efficient data access.

  Built middleware stack for JWT authentication, authorization, CORS, rate limiting, and security enhancements.

  Dockerized the application for easier deployment and maintenance.

• Microservice E-Commerce Platform

  14/05/25, 12:23

  GitHub repo

  Designed and implemented modular microservices architecture separating user management, product catalog, cart, orders, payments, and notifications.

  Built NGINX API Gateway for request routing, load balancing, and traffic management, reducing latency by up to 10% under load.

  Integrated Stripe for payments, Twilio for notifications, and MongoDB/PostgreSQL for flexible persistent storage across services.

  Containerized all components with Docker/Docker Compose; established GitHub Actions CI/CD for automated testing/builds.

  Applied environment-based configs, caching, and third-party integrations for maintainable, production-grade systems.

• Backend Developer

  Delivery Point Logistics

  location: Tubli, Manama - Remote | to 2024-03-31

  Developed and maintained RESTful APIs using Go and Node.js, serving over 50,000 daily active users with 99.5% uptime.

  Implemented Redis caching layer that reduced database query load by 60% and improved API response times from 250ms to 35ms average.

  Built automated data pipeline using PostgreSQL triggers and background workers to process 10,000+ user transactions daily.

  Collaborated with senior developers to refactor monolithic codebase into modular architecture, improving code maintainability and reducing bug resolution time by 40%.

  Integrated third-party services including SendGrid for email notifications, AWS S3 for file storage, and Stripe for payment processing.

  Participated in code reviews, wrote comprehensive unit tests achieving 75% code coverage, and documented API endpoints using Swagger/OpenAPI.

  Utilized Docker for local development environments and contributed to CI/CD pipeline setup using GitHub Actions for automated testing and deployments.

  Worked in Agile/Scrum environment, participating in daily standups, sprint planning, and retrospectives while managing tasks through Jira.

  Assisted in database optimization by creating indexes on frequently queried columns, reducing query execution time by 45%.

  Provided on-call support rotation, troubleshooting production issues and implementing bug fixes with average resolution time of 2 hours.
