What I'm looking for

I’m looking for an R&D role where I can own the full stack—from device protocols and cloud services to mobile UX—while running fast innovation cycles supported by strong CI/testing. I also want to apply LLM tools to practical workflows and prototypes.

I’m an R&D engineer focused on end-to-end product delivery—bridging physical sensors and industrial protocols through cloud backends and into native mobile experiences. I’ve built production systems that connect devices and translate telemetry into usable data and features.

On the cloud side, I’ve implemented AWS production infrastructure (IoT Core, Lambda, Cognito, Amplify, S3, RDS, DynamoDB) and integrated mobile clients with those services. On mobile, I develop in Kotlin with Jetpack Compose and apply MVVM and Clean Architecture to ship reliable apps, while also expanding delivery options with Flutter where it improves outcomes.

I’m equally comfortable in prototyping and quality engineering: I lead innovation cycles from problem discovery to functional prototypes (including hardware mockups) and user validation, then back it up with automated testing and CI using JUnit, Mockk, Espresso, and GitHub Actions. I also augment my workflow with LLM-based tooling (Claude API, Ollama, agentic workflows, MCP servers, and AI-assisted development) to accelerate engineering and improve how features are built.
