KenyaWhat I'm looking for
Result-driven Mobile Engineer with 6+ years of hands-on experience delivering scalable mobile applications across fintech, banking, and enterprise environments.
Expertise in Kotlin, Java, XML, Jetpack Compose, Android SDK, Clean Architecture, MVVM/MVI, Coroutines, Room, Firebase, REST API integrations, and Play Store delivery with a passion for solving complex technical problems. Successfully developed a high-traffic digital-lending app serving more than 500,000 monthly active users at 99.97% crash-free with a 4.65 out of 5 stars Google Play rating. Looking to contribute to a dynamic team focused on cutting-edge technology.
Experience
Work history, roles, and key accomplishments
• Led Android delivery in Kotlin, Compose, and MVVM/MVI, growing installs 85% in 28 days to 31,800 devices.
• Rebuilt the loan journey offline-first (Room, WorkManager); Play rating up to 4.65 stars at 99.97% crash-free.
• Owned staged rollouts and hotfixes; 89% adoption within an hour.
• Built a KYC, biometric-auth, and secure fund-disbursement app for branch staff, from architecture to staged internal release.
• Field teams lost data during outages, so I engineered offline-first Room/WorkManager sync: zero data loss, auto-sync on reconnect.
• Automated signed CI/CD builds, cutting release prep 60%.
Maintain production Spring Boot / Spring Security REST services for Safaricom
enterprise systems, with JUnit + Mockito test coverage gating Jenkins CI/CD
releases and secrets managed through CyberArk.
• Hired to take Hela Pesa from zero to launch: built onboarding, lending, repayments, and account management in Kotlin (MVVM, Room, Retrofit/Ktor) and shipped to Google Play.
• Cut loan-application drop-off 80% by instrumenting funnels with Firebase Analytics and fixing the worst steps.
• Stood up FCM, Crashlytics, and Sentry for same-day triage.
Trained developers in Java, Kotlin, and the Android SDK to a 90% course-
completion rate while building and maintaining the academy’s educational apps.
