Backend Architect, Security Sentinel
I'm Usama Amjid, a backend engineer specializing in high-performance Node.js ecosystems. I build secure, high-performance Node.js services that run reliably under load. Over the years, I have:
▹Worked on microservices architectures using Redis jobs/queues
▹Handled heavy tasks with Node.js worker threads
▹Created real-time features using WebSockets
▹Written complex MongoDB aggregations
▹Applied cipher techniques for encryption/decryption
▹Used JWTs for secure role-based API access
▹Implemented Redis caching with proper invalidation
▹Designed and optimized RESTful APIs
▹Followed best project-structure patterns
I pay attention to clean code and maintainable repo patterns because well-structured code matters when teams grow or projects evolve. Always open to discussing new ideas or collaborating on backend challenges. Feel free to connect and chat about building robust systems!

Key milestones and contributions in my backend development career

- ▹Designing and Building Robust APIs: I’ve developed a range of RESTful APIs that power everything from product reviews and user feeds to comments, likes/dislikes, and even dynamic rating calculations. Improving our MongoDB database structure and optimizing queries have been key to ensuring the system remains fast and reliable, even under heavy load.
- ▹Enhancing Data Processing: One of my proudest achievements was reworking our data collection process. I implemented a web scraper that uses worker threads to manage multiple, concurrent requests and built in failover and retry mechanisms. This has made gathering product details and reviews from various publishers both efficient and resilient.
- ▹Enabling Real-Time Communication: For our internal management tool, I built real-time collaboration features using Socket.IO. This included creating dynamic workspaces and chat rooms for one-on-one, group, and channel conversations, as well as developing a notification system that supports both targeted and group mentions.
- ▹Implementing Security and Compliance: Security is always front and center in my work. I’ve integrated secure authentication systems using JWT with private/public key encryption. In projects like the Payee-Backend, I designed KYC processes that securely manage user identity verification, ensuring that sensitive data is handled with the utmost care.
- ▹Developing Scalable Microservices: In a multi-microservice environment such as Bondii, I built a dedicated user/auth service. This service not only handles everyday user operations but also supports administrative tasks for business and tenant accounts. Incorporating tools like Redis for session management and Prometheus for monitoring helped ensure the system could grow along with the user base.
