Olayinka Kareem

I am a Senior Software Engineer specializing in backend development, cloud technologies, and scalable system design. I have designed and built systems used by millions of people across over 10 countries, delivering reliable, high-performance applications in fintech, edtech, and digital platforms.

While backend engineering is my core strength, I also have full-stack development experience, enabling me to contribute across the entire application lifecycle. My expertise includes building robust APIs, microservices, and distributed systems using technologies such as .NET, Node.js, and modern databases. I work extensively with cloud platforms, containerization, IAS (Terraform) , Production Monitoring, and CI/CD pipelines to deliver secure, scalable, and maintainable solutions.

In addition, I have working knowledge of cross-platform mobile development using Flutter, Dart, and React Native, as well as game development using the Unity framework with C#. This allows me to collaborate effectively across web, mobile, and interactive applications.

I have experience leading and contributing to end-to-end product development, integrating third-party services, and implementing real-time features. I enjoy translating business requirements into practical technical solutions that create measurable impact.

I am open to opportunities where I can help build impactful, scalable software.
