At Metagle, I worked on multiple products ranging from fintech apps to trading and crypto platforms. My role involved building secure payment features in Flutter apps like VivaKard and RadsCard, enhancing the Tbay trading platform with real-time rate comparison, and creating a crypto dashboard with React and TypeScript. I also developed Card Radar using Nuxt.js and Supabase with dynamic charts, and implemented a single sign-on system to unify multiple apps. These contributions improved user experience, enabled faster onboarding, and added real-time insights for thousands of users.

I contributed end-to-end on a crypto investment and social platform, building both web and mobile apps. My work included migrating the React app to Next.js for performance, adding Redis caching to cut API calls by 70%, and creating a React Native app supporting multiple languages and currencies. I integrated global payment options like Stripe, PayPal, Google Pay, Apple Pay, and Coinbase, achieving a high transaction success rate. I also built social features like posts, groups, and messaging, and automated data pipelines that processed 500+ daily updates from YouTube, Reddit, and Twitter to give users real-time market insights.

At Kaspar, I worked across telecom, retail, and food delivery solutions. I developed TELA, a SaaS tool for African telecoms, which processed over 1M records and cut reporting time from an hour to 5 minutes. I built a digital inventory system for a Japanese auto client, reducing discrepancies by 28%, and a complete POS system that made checkouts 25% faster. I also contributed to a food delivery platform connecting 65+ home cooks with customers, improving order speed by 30%. Alongside development, I managed AWS infrastructure, set up CI/CD pipelines with Jenkins and Docker, and optimized databases to ensure reliability and scalability.

Web Developer Internship at Infology Solutions

April 1, 2021 - August 1, 2021

As an intern, I focused on improving client websites and building small-scale platforms. I rebuilt a UK accounting firm’s site, boosting PageSpeed by 90% and helping it rank on the first page of search results. I developed a daycare management platform with scheduling and parent portals, cutting admin workload, and built an e-commerce site with real-time chat that improved sales and engagement for an American influencer. I also gained hands-on experience in hosting, cPanel, and database management while supporting senior developers on international projects.
