Message

At Timedrop Technology, LLC, I develop full-stack features for the Timedrop mobile application using React Native and JavaScript/TypeScript. I integrated Gemini API-powered AI chat into application screens and build Firebase backend functions that work with Firestore.

At Four13 Group, I delivered frontend and backend features for Shopify and BigCommerce e-commerce platforms. I also developed backend functionality for an in-house application using Strapi and Node.js, and built Shopify services and integrations with Gadget.dev and the Shopify API.

As a freelance Full-Stack Mobile Developer at Beyond Business Virtual Assistants, I developed a cross-platform Flutter and Dart application connecting clients and virtual assistants through a matching workflow. Earlier, as an Assistant Research & Development Engineer at Advanced World Solutions Inc., I developed Windows sub-applications by migrating legacy VB6 code and contributed to web and desktop application development.
