I'm a results-driven backend developer with ~4.5 years of experience specializing in the Node.js ecosystem. I architect and build high-availability, scalable backend systems using TypeScript, PostgreSQL/MongoDB, and AWS cloud services. I thrive on translating complex business requirements into robust, maintainable code, with a focus on performance optimization and system reliability.
Languages & Frameworks
Data & Infrastructure
- Architected High-Performance Systems - Redesigned system flows using Redis queueing services and AWS Lambda, significantly improving performance and reliability for data reconciliation at Broadcasters IT Solutions.
- Optimized for Scale - Implemented Redis caching for a high-traffic hotel booking platform and a loan management system, reducing database load and improving response times by ~40% .
- End-to-End Ownership - Led the backend development for complex projects including a full-featured Employee Management System (EMS) with RBAC, a real-time Food & Grocery Delivery app using WebSockets, and a HIPAA-compliant healthcare diagnostics platform.
Here are some of the complex, real-world systems I've built and contributed to:
| Project | Description | Core Tech |
|---|---|---|
| Agoda-Style Hotel Booking | Backend for high-traffic hotel reservations. Implemented complex search filters with Redis, designed idempotent payment gateways, and managed booking state machines to prevent double-booking. | Node.js, TypeScript, Redis, PostgreSQL |
| Furaha Financial (LMS) | A school-fee loan management platform handling end-to-end loan applications, approval workflows, and disbursement tracking. Boosted performance with PostgreSQL (AWS RDS) and Redis. | Node.js, TypeScript, AWS RDS, Redis |
| Speedyy (Food & Grocery Delivery) | Developed scalable backend microservices for a hyperlocal delivery app. Built real-time order tracking with WebSockets and a robust queueing system with Bull/Redis for high-volume order processing. | Node.js, JavaScript, WebSockets, Bull, Redis |
| Xyla Health (Healthcare) | Contributed to a HIPAA-compliant diagnostics platform. Developed secure modules for patient appointments, ECG/SpO2 data reporting, and audit logging for sensitive medical records. | Node.js, TypeScript, PostgreSQL |
| Lumi Matrimony | Developed core backend services for a matchmaking app with secure matching algorithms and privacy controls. Built RESTful APIs and integrated WebSockets for real-time chat with JWT authentication. | Node.js, TypeScript, Express.js, WebSockets |
Actively solving DSA problems to strengthen backend system design fundamentals.
- I also write on - dev.to/mohinsheikh
- I’m currently diving deeper into - Advanced system design patterns and event-driven architectures.
I'm always open to discussing backend architecture, new technologies, or potential collaborations.
