What I'm looking for

I'm looking for opportunities where I can build practical web or mobile products, improve digital operations, solve technical problems, and work closely with clients and business teams.

I deliver end-to-end web and mobile applications for Otech clients, from React front ends and Python back ends to SwiftUI iOS experiences. My work includes a six-player Rummy game, the PlayLocal recreational-group app, and an offline Bible verse projection tool using Vosk speech recognition.

At Shappai.co, I improve IT infrastructure through hardware and software solutions while managing invoices, documentation, correspondence, and digital product catalogues for interior finishing materials. I also provide technical consultation that helps clients work from accurate product specifications.

I've contributed to AI model training and evaluation at AfterQuery and use Claude in Xcode and VS Code to support development, debugging, and code review. I bring hands-on IT operations, client communication, and full-stack delivery to digital initiatives aligned with business goals.
