About

I’m strongest on small, product-focused teams where one experienced engineer can create a lot of leverage early. I work across the full path from discovery and planning through implementation, release, and iteration, and I care about making strong technical decisions up front so teams can move faster with less rework.

My core stack is Kotlin, Jetpack Compose, coroutines, Flow, and modern Android architecture. I focus on code that is understandable, testable, and practical to maintain, with strong attention to user experience, performance, and release quality.

I also use AI-assisted workflows to speed up planning, prototyping, and implementation while keeping human judgment on architecture, product tradeoffs, and code quality.

What I bring

End-to-end Android ownership, from idea to shipped product
Strong Kotlin and modern Android fundamentals
Pragmatic architecture that supports fast iteration
Close collaboration with product and design
Clear communication and dependable execution
AI-assisted workflows used in a disciplined, quality-focused way

Skatespots

Skatespots is an end-to-end skate spot discovery app that I designed and built across both the backend and Android client. The app gives skaters a way to find nearby spots on a map, create and share spot listings, upload photos, add terrain tags, save favorites, and manage their profile.

I built the backend as a production-ready TypeScript API on Cloudflare Workers with authentication, user profiles, spot CRUD, photo uploads, check-ins, favorites, pagination, validation, ownership rules, and admin tooling. The API supports dev and production environments, D1 migrations, R2-style image workflows, JWT access and refresh tokens, Cloudflare Access-protected admin routes, CI deploy health checks, and a documented request/response contract for mobile clients.

On Android, I built the app using Jetpack Compose, Material 3, Clean Architecture, and an MVI presentation pattern. The project is structured with feature modules for screens, shared core UI components, a pure Kotlin domain layer, and a data layer backed by Retrofit, OkHttp, Room, DataStore, Hilt, Coroutines, and Flow. The Android app connects directly to the Cloudflare-hosted API, with debug and release builds targeting separate backend environments.

The current Android experience includes login/signup, a personalized home screen, searchable spot cards, interactive map discovery, favorites, spot editing, photo management, tags, and profile editing. I’m also planning to build the iOS version soon, using the same backend API and product model.

Edit Playlist

Shipped playlist editing so users could manage saved sounds more easily in a core part of the app experience. The challenge was keeping add and edit behavior consistent while still moving quickly for release. I built it with a single immutable UI state, intent-driven MVI flow, and layered use-case and repository boundaries to keep behavior predictable and the implementation easy to extend and test.

Routine Swap

Delivered routine swapping so users could change routines without breaking schedule constraints or losing structure. This flow touched core product rules, so reliability and clarity were critical from the first release. I owned the Android implementation end to end, using clear UI state modeling and analytics instrumentation to make the initial release dependable and post-launch iteration easier.

Rick and Morty Compose

Built this project to demonstrate a production-minded Android foundation for scalable feature delivery. It highlights modular structure, predictable UI state, and practical architecture choices that support smooth user flows as complexity grows. I used a layered approach with modern Android tooling to keep behavior clear, testable, and straightforward to maintain.
