I build, modernise and rescue production mobile apps.
I have been shipping mobile products since 2012, starting with native iOS and Android, then moving deeply into React Native, bare React Native apps, Expo, EAS, CI/CD, observability and multi-brand mobile platforms.
My strongest work is helping teams ship mobile apps that are reliable, maintainable and easier to release.
Building, refactoring and maintaining production apps across iOS and Android.
Shared architecture, monorepos, native integrations, app store delivery, release governance and reusable platform patterns.
GitHub Actions, Bitrise, Expo EAS, Fastlane, automated builds and safer release workflows.
Maestro, Appium, WebdriverIO, BrowserStack, Sentry, New Relic, crash investigation and production monitoring.
Using Claude Code, Cursor, Codex, GitHub Copilot and custom scripts to speed up PR review, debugging, release investigation, Jira updates and engineering workflows.
LLM-powered app features, document parsing, image analysis, RAG-style workflows, on-device inference experiments and mobile-first AI product design.
My AI foundation includes academic and research work in self-driving cars, synthetic adversarial data, computer vision, robotics, embedded systems and real-time intelligent systems.

I am strongest when a team needs an experienced mobile engineer to:
- Stabilise or modernise a React Native app
- Move from bare React Native to Expo
- Improve CI/CD and release pipelines
- Reduce crashes and improve observability
- Fix difficult iOS, Android or app store issues
- Build reusable mobile platform patterns
- Add practical AI features or AI-assisted engineering workflows
If you need help with a serious mobile app challenge, send me a short brief.
I can usually tell quickly whether the problem is architecture, release process, observability, native integration, testing or team workflow.
