As a Full Stack Developer at Metadesign Software Services, I've developed impactful SaaS application named Dymond Management System, including a merchant onboarding system that enhanced security and streamlined setup processes, and a payment gateway app that efficiently handled transactions and improved user convenience. I optimized SaaS app performance with GraphQL and implemented OTA updates with AWS IoT Core. Additionally, I created an inventory management app for gumball machines with integrated IoT for real-time monitoring, significantly boosting operational efficiency. Proficient in Node.js, Express.js, Next.js, React.js, GraphQL, AWS, MedusaJs, TypeScript, and React Native.

Worked on a relationship problem solver application where I utilized MongoDB to implement tree structures for the first screening process questions. I also designed and developed the UI for both the landing page and the questioning interface of the application. Additionally, I wrote APIs using Go to handle user information and send email alerts. The technologies I employed included React.js, MongoDB, and Go (with Go Mux).
