Rajendra Bisoi

I am a backend engineer with 3+ years of experience building and operating scalable, high-concurrency systems using Python, Django, NodeJS/NestJS, AWS, PostgreSQL, and Redis.

I design fault-tolerant services, asynchronous processing, and distributed workflows that handle 10k+ jobs/day, and I ramp up quickly on new backend stacks including Java-based systems.

My recent work includes improving platform reliability from 68% to 97% by optimizing WebSocket workflows, creating priority Redis command queues to manage concurrent requests, and reducing backend latency from 4s to 1.8s through caching and task execution improvements.

I automate operations with CI/CD, containerization, and cloud-native patterns, and I focus on observability, disaster recovery, and cost-efficient architectures that support production stability and scalable growth.
