Ergatta is a connected fitness gaming platform offering rowing, treadmill, and bike workouts. I joined as the fourth employee and built the foundational Android screens from day one: onboarding flows, workout libraries with filtering and sorting, custom Canvas animations, and the full pre- and post-workout screen flows across six game modes.

As the product matured, I transitioned screens from XML to Jetpack Compose, co-proposed and implemented a gRPC/Protocol Buffers consolidation that replaced multiple fragmented REST endpoints with single-screen services, and expanded into Unity/C# development. I built and owned the data pipeline between Android and Unity, established the Unity UI Toolkit framework adopted by the team, and led the complete screen flow for the Battler game mode as a senior engineer.

Invikey is a personal Android input method editor (IME) prototype I designed and built solo, reimagining mobile text input through a novel interaction model. The core concept: a fully functional keyboard that can become visually invisible, giving users their full screen while typing eyes-free, the way a skilled typist never looks at a physical keyboard.

Rather than relying on existing IME documentation (which covers only keyboard display), I adapted Android APIs in novel ways to build an input detection system that functions as a performant background service with no visual footprint. The design decisions were shaped entirely by two years of using it as my actual daily keyboard. Every iteration came from hitting a real pain point, not guessing at what might work.

While working as an Epic EMR trainer at Providence Health Services, I identified an operational gap in how the lab handled specimen tracking and reporting. No tool existed to solve it, so I taught myself web development from scratch and built one.

I met regularly with lab staff and leadership to gather requirements, iterated on the system based on real feedback, and maintained it post-deployment as needs evolved. The entire project was self-directed, from recognizing the problem to delivering a working full-stack solution, with no engineering background or formal training at the time.
