Focus
I work across the stack of a mobile app, from system design to a single frame.
Core expertise
- Kotlin and Jetpack Compose: UI, state management, performance
- Coroutines and Flow: structured concurrency, reactive pipelines
- Kotlin Multiplatform: shared business logic across platforms
- Modularization and scalable project structure
- Clean Architecture and unidirectional data flow
- Performance profiling and memory optimization
I design systems with clear boundaries, predictable data flow and abstractions that stay maintainable.
Technical leadership
- Leading cross-functional work across Android, backend, product and design
- Setting architectural direction and reviewing critical technical decisions
- Improving code review processes and engineering standards
- Mentoring engineers and supporting their growth
I'm comfortable at both levels: high-level system design and low-level UI performance tuning.
UI and visual engineering
- Interfaces that are functional, intuitive and coherent
- Layout behavior, animation smoothness and interaction details
- Shaders and custom rendering with AGSL and OpenGL
- Visual effects and advanced transitions in Compose
I experiment with graphics to see how far a modern Android interface can go.
Experience
Engineering across products used by millions.
From messaging and streaming to mapping, precision agriculture and visual computing.

Writing
Since Android 13 you can put a shader on any view. Most developers haven't tried yet.
I write to help break down that wall: a free book and a series of hands-on tutorials.
The book · free online
Runtime Shaders for Android and Jetpack Compose
From drawing a circle by measuring distance to signed distance functions and textures. Read the chapters in order; each builds on the one before.
