What I'm looking for

I'm looking to build scalable full-stack web applications, especially enterprise products with complex workflows, data-heavy interfaces, secure APIs, and performant reusable frontend architecture.

I've built enterprise web applications for Insonix – Enterprise Unleashed and xByte Solutions, focusing on scalable, data-heavy user experiences.

For Phoenix, I maintained the React, TypeScript, and Material UI frontend architecture, added persistent Redux sorting and filtering, upgraded Material UI from v5 to v6, and cut CRA build time by 50%.

On IntechGo, I developed an analytics and management application from scratch, connecting a React frontend with Python FastAPI REST APIs, MSAL authentication, SharePoint integration, and role-based access control.

At xByte Solutions, I build responsive interfaces for Kersia, an enterprise food safety platform, including offline-first functionality with IndexedDB and reusable component architecture. I also built Strangers Meet, a real-time anonymous video chat app using Socket.IO, WebRTC, Node.js, and Express.
