At Byteoski Developers, I am working as a Full Stack Developer where I design and build scalable, production-grade web applications using Next.js, Django Ninja, PostgreSQL, Celery, Redis, and Docker.

I have also built an AI-powered document extraction system using OpenAI GPT and Google Gemini to automate PDF and image data processing with high accuracy, while collaborating closely with cross-functional teams in an Agile environment across the full software development lifecycle.
MERN Stack Developer
Preva Care • Part-time
May 2025 - Aug 2025 • 3 mos
At Preva Care, a healthcare startup, I worked as a Software Developer where I single-handedly built a Clinic Management System, developing 100+ secure and scalable REST APIs with role-based access control. I integrated AWS S3 for secure medical document storage, configured and optimized Nginx as a reverse proxy and load balancer, and implemented tele-consultation features using the Agora SDK along with WhatsApp messaging via Gupshup. This role gave me deep exposure to healthcare workflows, data security, and building reliable systems in a fast-paced startup environment.
