What I'm looking for

I’m seeking a remote Android development role where I can collaborate with a skilled, diverse team to build impactful, user-centered products. I value flexible, results-driven environments that encourage continuous learning, innovation, and the adoption of modern technologies like Kotlin, Jetpack Compose, and cloud integration

I am a dedicated mid-level Android developer with a Bachelor's in Software Engineering and over four years of hands-on experience building native and hybrid mobile applications. I specialize in Kotlin and Jetpack Compose, and I embrace clean architecture and performance optimization to deliver user-focused features.

My experience spans leading mobile teams and projects—implementing real-time features, MQTT walkie-talkie functionality, EKYC solutions, and integrating cloud CI/CD with Azure and DevOps tools. I have delivered production apps, improved customer self-service capabilities at an insurance provider, and collaborated with international teams.

I am results-driven and continuously learning, with formal training from the Google Africa Developer Scholarship and other accelerators. I manage projects end-to-end and prioritize maintainable code, testing, and strong cross-functional communication.
