What I'm looking for

I’m looking to build reliable, user-focused web and mobile products—shipping end-to-end features, improving UX and performance, and developing scalable systems with React/React Native and NestJS.

I’m a software engineer with 4 years of experience building production web and mobile applications in React, React Native, Next.js, and NestJS. I’ve shipped a healthcare app serving 500+ users and I enjoy owning features end-to-end—from UX flows to backend integration.

In my current work, I build core HMO mobile app features for Android and iOS, including an appointments module for booking and tracking visits, plus reporting workflows that improve transparency and support responsiveness. I also partner with QA and backend teams to resolve bugs and implement real-time data synchronisation for stability across platforms.

I also independently built and maintain a full inventory and financial-reporting system for a distribution business, digitising 184 SKUs and automating P&L generation and branded PDF reporting. I’m an active open-source contributor with 368 merged pull requests across public repositories spanning the Stellar/Soroban and Starknet/Cairo ecosystems.
