Smart Spending

A professional and visually appealing online marketplace for e-vouchers from top global retailers, where I led the front-end development, testing, and deployment. I implemented smooth, PCI DSS-compliant checkout flows using Checkout.com. Leveraging GraphQL, I optimized data management and caching, which enhanced app performance by nearly 40%, improving load times and responsiveness. By integrating Apple Pay and Google Pay through Checkout.com, I provided users with secure, convenient payment options. React Native, Kotlin, Swift, Firebase, Checkout.com.

Ezyorganizer

As the full-stack and sole developer, I led the end-to-end development, testing, and deployment of a React Native-based event management app serving over 10,000 users. I also implemented a retrieval-augmented generation (RAG) service using OpenAI's language model. This service processes and cleans user data, runs it through an RAG pipeline, and stores vector representations in a database. These vectors enhance the model's ability to assist users effectively with task and event management, offering a more personalized and intelligent experience.

I also implemented functionality to detect certain heart conditions, promoting early diagnosis and proactive management. This solution lets users use their health metrics in real time, improving health awareness and monitoring.

The platform helps organizations keep employees safe and informed by ensuring that the right information reaches the right person at the right time. I was the front-end developer in charge of designing interactive UI screens. I also managed the API integration to organize and display complex, real-time data to the users.
