I will build a kotlin android app or mobile mvp prototype
Lazaro R
About this gig
Have an Android idea you want to validate? I build native Android features, prototypes and scoped MVP slices in Kotlin, using Java where it fits. Kotlin is my primary working language, and I bring substantial professional Java experience as well. My 7+ years in senior software engineering inform the architecture, API integrations, edge-case handling and testing behind each delivery.
Agentic AI workflows help me move quickly through implementation and iteration. I guide the technical decisions, review the code and verify the core user flows in a test build. Each package has clear screen, flow and integration limits; new backend services, custom visual design, Play Store submission and complex device features need a separate scope.
For a polished MVP 1.0/2.0, message me with your target users, screens, core flow, existing API documentation and must-haves. I will confirm the deliverables, timeline and fixed price before we begin.

I am a senior-level backend software engineer with over 7 years of experience designing and delivering production APIs, distributed services, and payment platforms. I specialize in Kotlin and Java, helping product teams turn clear ideas into maintainable backend features and milestone-based MVP releases. I bring strong hands-on depth in API design, event-driven systems, and cloud-ready delivery.
FAQ
Can you build a complete production app?
I can work from a focused feature through a polished MVP 1.0/2.0. Larger builds need a custom scope. Message me with screens, core flows, integrations, and target devices so I can confirm timeline and price.
Do you support Java Android projects?
Yes. Kotlin is my primary day-to-day language, and I have substantial professional Java experience too. I can build a scoped Android feature in either. Share your codebase, requirements, and Android targets so I can confirm the best fit.
Does the package include design, backend, or Play Store release?
The package covers app implementation within the listed screen and feature limits. Custom UI/UX design, new backend services, and Play Store submission are separate. One API integration is included only where the selected package specifies it.
What do you need from me before you start?
Please share your target users, screen list or sketches, one core user flow, must-have behavior, and target Android versions or devices. Include API documentation and test credentials when needed. Do not send production passwords or private secrets.
