What I'm looking for

I'm looking to build scalable cross-platform mobile and frontend products, lead architecture and feature delivery, mentor engineers, and explore Generative AI and backend technologies.

I've built and maintained scalable React Native and web applications for Feedlyx, GeekyAnts, In Time Tec, and SimplexMLM. As the sole developer of Feedlyx, I own product design, architecture, development, and deployment for a multi-tenant customer feedback SaaS with OpenAI-powered sentiment analysis.

At In Time Tec, I led teams of 4–5 engineers and delivered three mobile and two web apps used globally. I've improved performance, automated releases with GitHub Actions and Fastlane, increased regression detection by 35% through Jest and Appium testing, and built products ranging from AI-assisted dental planning to merchant dashboards and large-scale childcare applications.
