Professional Projects

As a hands-on full stack software engineer, I build complete applications by managing the entire development lifecycle. From designing database schemas and backend logic to crafting intuitive user interfaces, I bridge the gap between frontend and backend to deliver functional, end-to-end solutions. Each project reflects my ability to own a product from start to finish.

Invoice Portal
Role: Full-Stack Developer
As the sole full-stack developer, I engineered a comprehensive Invoice Portal designed to automate complex financial workflows. I led the entire development lifecycle, creating a system that facilitates external invoice submissions while managing internal, role-based approval sequences. By building a responsive front-end with Bootstrap and a robust back-end using Django and MySQL, I delivered a seamless end-to-end user experience.

The platform integrates real-time payment monitoring, automated alerts, and budget aggregation tools to provide clear financial oversight. This project generated $325K in annual cost savings and improved operational efficiency by 0.75 hours daily for over 50 users, directly enhancing corporate budget control and team productivity.
