Hi, I'm Temidayo Animasaun.
I build reliable web, mobile, and decentralized applications. Over the past 4 years, I've engineered solutions across Fintech, EdTech, Health, Social Networks, and Sports.
My day-to-day work centers around the JavaScript & TypeScript ecosystem—building high-performance frontends with Next.js, resilient backend APIs with Node.js & Express, and mobile apps with React Native. I also build smart contracts and decentralized applications on the Sui blockchain using Sui Move.
