About

I'm a Fullstack Software Engineer with a strong focus on building production-grade SaaS products and scalable web systems. I work across the entire stack — from architecting data models and API layers to crafting performant, accessible frontends.

Worked at Synatic AI (USA), I contributed to 3D modeling pipelines and AI-driven systems, worked at the intersection of complex data processing and modern web interfaces.

My engineering approach prioritizes clean architecture, real-world impact, and systems that scale — not just code that works.

Contributor — not owner

A production-grade healthcare platform serving five distinct user roles: Doctors, Nurses, Patients, Ambulance Drivers, and Customers. Built with Next.js, Firebase, LiveKit, and Stripe — the platform handles virtual consultations, medical record management, real-time ambulance tracking, and secure payment processing entirely in the browser.

Key technical contributions span role-based access control via Firebase Auth and Admin SDK, LiveKit video room integration with server-side token generation, Stripe Checkout with Firestore payment tracking, and real-time location and transport request management via Google Maps API.


Real-time messaging application built with React, Vite, and Firebase. Features include live messaging, Firebase Cloud Messaging push notifications, and a fully responsive UI optimized for performance across devices.


Recipe discovery and sharing platform built with React and Next.js. Focuses on clean UX, fast data fetching patterns, and a scalable content structure suitable for community-driven content.


Personal portfolio built with Next.js — showcasing projects, experience, and technical depth with a focus on performance and clean design.


Experience

Fullstack Software Engineer — Synatic AI (USA) June 2025 – December 2025 Worked on 3D modeling pipelines and AI-driven web systems. Built and maintained complex data processing workflows integrated with modern frontend interfaces.


Code Coach — CodeSpace Academy June 2024 – February 2025 Mentored junior developers through JavaScript engineering fundamentals, code reviews, project feedback, and structured learning paths. Helped students bridge the gap between theory and production-ready code.
