Ayorinde Timilehin

I'm a full-stack software engineer with over 7 years of hands-on experience developing and optimizing scalable web applications that improve how people live and work. I've worked both independently and as part of cross-functional teams to deliver impactful solutions for sectors including digital identity, enterprise collaboration, and financial services.

My expertise spans the JavaScript ecosystem MERN/MEAN stack, with deep proficiency in Typescript, React, Next.js, Angular, and Redux for building responsive and intuitive user interfaces. On the backend, I have hands-on experience with Nodejs, Nestjs, Java and Spring Boot, building RESTful APIs, integrating with SOAP APIs, relational and non relational databases, and delivering production-grade enterprise applications.

What drives me most is solving real problems and building useful products that people rely on. I take pride in writing clean, maintainable code and continuously improving my technical and product-thinking skills.

I've contributed to projects for an Atlassian solution partner and a digital identity solution provider, working on internal dashboards and complex B2B platforms—many of which serve thousands to millions of users. While these applications are protected under NDA, they demonstrate my ability to build maintainable, performant systems at scale.

More recently, I've been expanding into Web3 development, using Solidity, Ethers.js, and Ethereum tools to build decentralized applications and experiment with blockchain-based systems.

Outside of work, I unwind through sports—whether it's watching football, basketball, or Formula 1, or playing football with friends. I thrive in environments that encourage innovation, continuous learning, and collaborative problem-solving.
