Über mich
I’m A. M., a Senior Backend Developer. With over 12 years of experience, I specialize in building scalable, high‑performance systems using Java and Kotlin (Spring Boot) in microservices environments. Beyond code, I’m a proud Makerere University alumnus (BSc Software Engineering ’13) and a lifelong learner who thrives on optimizing databases, architecting event‑driven systems, and championing DevOps best practices
On GitHub, I describe myself succinctly: “A software developer with C#, Java, Kotlin and SQL” GitHub. On X (formerly Twitter), I’m known for my work in e‑mobility, AI/ML—and the occasional snarky quipX (formerly Twitter).
