Hey, I'm a Software Engineer at Biofourmis. I am a fullstack developer, working in Nodejs, Golang, React, GraphQL, etc.

I am also exploring the world of Web 3.

Experience

Researched Slack, Whatsapp, and other open source projects like Rocket.Chat, to come up with a future-ready modern architecture for instant messaging and chatrooms.
Solved for code maintainability and scale by using NestJS. NestJS allowed us to change our system's underlying infrastructure very quickly and efficiently.
NestJS helped us with experimentation as it is very modular and allowed us to change our infrastructure really easily.
Solved for concurrency by using Redis Adapter. It uses Pub/Sub mechanism to communicate with the different servers. Our single server can handle up to 2k+ concurrent users in EC2 t3.small instances.
Explored WebSocket options like sockjs, uwebsockets, etc as an alternative, and worked on the Nestjs middleware, NestJS makes switching easier.
CI/CD using docker to have professionally made builds and deployments to reduce our deployment time.
Skills : Nodejs, Nestjs, React, React Native, Docker, CI/CD

Integrated internal and external microservices using GraphQL and REST API.
We used GraphQL for client-side APIs to solve the under fetching/over fetching issue.
Developed producer and worker to process RabbitMQ queues for fast crawling.
Optimized Elasticsearch queries to return time-based priority response.
Created external API for Elasticsearch to be consumed by internal services.
Skills : React.JS, GraphqQL, Elasticsearch, RabbitMQ, REST API, Nodejs
