Backend Engineer at PerfectionGeeks Technologies who built CEOS’s multi-tenant accounting platform and cut report generation to under 2 seconds.
IndiaWhat I'm looking for
At PerfectionGeeks Technologies, I architected and built the backend for CEOS, a multi-tenant SaaS accounting platform, using NestJS, MongoDB, MySQL, and Redis. I designed modular microservices with API gateway patterns and integrated Stripe and Razorpay payments.
I optimized MongoDB queries and indexing, reducing API latency by 40% and report generation time from 10 seconds to under 2 seconds. I also built Safe Spirit, a regulated e-commerce platform that achieved average response times under 100ms through Redis caching.
I’ve automated AWS infrastructure tasks with Shell scripts and deployed services using Docker and GitHub Actions. Earlier, I contributed backend features to 1viewtask and built REST APIs for Orbit Mart; I’m currently focused on robust backend systems, scalability, and product development.
