I help startups, founders, and product teams build reliable Android apps, SaaS platforms, dashboards, MVPs, booking systems, customer portals, and workflow tools. My background combines two strengths: 1. Senior Android Engineering I build production Android apps using Kotlin, Jetpack Compose, Clean Architecture, MVVM/MVI, Coroutines, Flow, Firebase, REST APIs, Room, Paging 3, CI/CD, analytics, and performance optimization. I have worked on Android platforms serving over 1.5M+ users across African markets, where performance, reliability, and user experience directly affected how people accessed services every day. 2. Product Building & MVP Delivery I also help businesses turn practical workflows into usable software products. That includes SaaS platforms, admin dashboards, marketplaces, customer portals, payment flows, reporting systems, and internal business tools. Recent products I have built or worked on include: • MotiAutoCare — garage management SaaS for repairs, quotations, invoices, inventory, payments, users, dashboards, and reporting • NyumbaChef — marketplace MVP for home-chef bookings, trust flows, early signups, and payment journeys • AskDrWaihuini — mentorship platform for bookings, sessions, payments, resources, reviews, and admin operations • EmberRise — mental wellness platform with mood tracking, journaling, therapist discovery, and wellness content • Large-scale Android platforms — used by 1.5M+ users across different markets • Supply-chain mobile systems — supporting 2,000+ field operators and 50,000+ retail merchants I can help you with: • Native Android app development • Kotlin and Jetpack Compose features • Android architecture, refactoring, and performance optimization • MVP development • SaaS platforms and dashboards • Booking systems and marketplaces • Customer portals and admin tools • Supabase-backed applications • Workflow digitization • API integrations • Payment flows and reporting systems • Product research and launch preparation What makes me useful is that I can think beyond the task list.
