What I'm looking for

I’m looking to lead hands-on Android teams building scalable Kotlin apps with measurable impact, while applying agentic/AI tooling to automate delivery, improve code quality, and accelerate releases safely.

I’m a Senior Android Engineer with 7+ years designing, building, and scaling production mobile applications across live-streaming, telecom/VOIP, payments, and restaurant-POS—backed by a combined 2M+ downloads. I bring deep expertise in Kotlin, Java, Jetpack Compose, and MVVM/Clean Architecture, with a hands-on approach that keeps code clean, maintainable, and well-tested.

I lead teams and drive architecture decisions, code-review standards, and CI/CD release pipelines. I’ve integrated global payment gateways (Stripe, PayPal, Paystack, Interswitch, Pesapal, WebView payments) and delivered SIP/VOIP voice calling at scale using the Linphone SDK. I also build offline-first systems with conflict resolution and data integrity checks, improving stability and streamlining order-to-payment flows.

Recently, I’m extending my engineering foundation into AI and agentic development—trained by Anthropic in Claude Code, Agent Skills, and subagent orchestration. I now use agentic, CLI-driven workflows to automate scaffolding, refactoring, test generation, and build/release tasks while mentoring engineers to adopt safe, steerable multi-step AI workflows.
