Hi, my name is

Yeasir Arafat

Full-Stack Software Engineer | Systems Architecture

I’m a Full-Stack Production Engineer who designs and builds complete software systems from architecture to live deployment. I work across Django, Next.js, React, Flutter, React Native, Docker, and DevOps, creating scalable web and mobile applications used by real users. My focus is on clean system design, robust APIs, containerized deployments, and production reliability. From database to UI to server infrastructure — I build software the way it runs in the real world.

About

I am a Full-Stack Production Engineer specializing in designing, building, and deploying complete software systems from architecture to live production. I work across backend, frontend, mobile apps, DevOps, and system architecture, turning ideas into scalable, real-world applications used by real users.

My core expertise includes Django, Django REST Framework, Next.js, React, React Native, Flutter, Node.js, Docker, CI/CD, Nginx, PostgreSQL, Redis, and Linux servers. I have architected and deployed multiple systems from scratch, including live web platforms and mobile applications published on the Google Play Store.

I design how the entire system works — from database architecture, REST API design, authentication with JWT, and frontend experience to containerization, environment-based configuration, and automated deployment pipelines using Docker and GitHub Actions.
