About me
Intro
Hi, I’m Abdulrosheed Lawal, a software developer with 5+ years of experience. I specialize in C# .NET, working on scalable backend systems, APIs, and cloud-based applications. Over the years, I’ve worked on projects across different industries, including fintech, healthtech, and education, building secure and high-performance applications. Some of my key contributions include: Developing a biometric-based transaction system, enhancing security and efficiency. Building a university portal system to streamline student and staff operations. Architecting and optimizing multi-tenant applications with PostgreSQL and MongoDB. Leading complex API integrations, including OAuth, OpenID Connect, and Keycloak. Mentoring junior developers and collaborating with teams across different time zones. One of the biggest lessons I’ve learned is that great software isn’t just about writing code—it’s about solving real problems efficiently. Beyond coding, I love sharing knowledge. I write about software development, career growth, and professional skills, and I’m passionate about mentoring aspiring developers. Outside of tech, I’m an avid football player and a huge fan of the game. When I’m not coding, you’ll probably find me on the pitch or analyzing matches. Always open to collaboration, learning, and building impactful solutions! 🚀
