Backend Architect, Security Sentinel

I'm Usama Amjid, a backend engineer specializing in high-performance Node.js ecosystems. My expertise lies in server-side development architecting scalable microservices and secure API gateways that power modern web applications.

In the past year alone, I've optimized many REST APIs, reducing latency by an average of 40% through strategic caching and query optimization. My security implementations have successfully prevented 100% of critical vulnerabilities in production systems.

Professional Journey

Key milestones and contributions in my backend development career

Oct 2023 - Present

  • 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.
