Dilip Pal

I’m a Software Engineer with 1.8 years of freelance experience delivering and deploying production systems for real clients and real users. I’m comfortable owning a project end-to-end—from architecture and server logic to cloud deployment and handoff.

In my freelance work, I built backend systems for 8 client projects across e-commerce, healthcare, and local business. I designed and documented 25+ REST APIs handling 2,000+ daily requests in production, enforced security with JWT-based authentication and Role-Based Access Control (RBAC), and built reusable backend modules (auth, file uploads, email/push notifications) that reduced backend setup time by about 30% on subsequent projects.

I also enjoy system design challenges: I built a distributed file storage system in C++17 modeled after the Google File System design, including chunking over raw TCP sockets, a heartbeat-based failure detector, automatic re-replication, and fault-tolerant reads. I’ve also decomposed a URL shortener into microservices with an API Gateway and a real-time analytics service, so failures and health checks are visible in one place.
