Front end, back end, mobile or AI. Put me anywhere.
I have shipped web apps, mobile apps, internal tools and AI features, and I pick up whatever the team needs next. Quick to learn, careful with the details, and used to shipping work that real people rely on.

Straight from the commit logs. Every project page has the full list.
- GymswellApp Store review turned the build down twice under guideline 2.5.4 for its audio background mode. The mode is gone, and the rest-timer notification still rings on time without it.
- GymswellA Learning section: 140 answers with their sources cited, short video reels that start on their own, and a picker to jump between topics.
- GymswellA timed exercise is a running clock on the Lock Screen Live Activity. The coach says what failed and retries server errors instead of going quiet.
- PlatefulEvery push to main builds the iPhone app and adds it to the family’s TestFlight group, with a web version for everyone else.
- GymswellOne phone, one owner: a second account on a shared phone never sees the first one’s workouts, units or settings.
What I bring
Whatever part of the product you put me on.
I have worked on every layer of a product: the screen people tap, the server behind it, the database under that, the AI in the middle and the pipeline that ships it. So wherever the team is short, I can step in and be useful quickly.
- 01
I learn fast
New codebase, new language, new tool: I get productive in days, not months, and ask good questions on the way.
- 02
I ship
Small, working steps that people can try early, instead of big changes that land all at once.
- 03
I own it
Tested, deployed and watched after launch. If something I built breaks, I am the first one on it.
Tools I work with
TypeScript, React, Next.js, React Native, Swift, Kotlin, Node, PostgreSQL, Supabase, Firebase, MongoDB, Python, OpenAI and Gemini, Docker, Azure, GitHub Actions.
