Hey, I'm Jeremiah πŸ‘‹

I make the tools that make the apps that make your life easier.
Somewhere in that chain, I'm having a great time.


What I Actually Do

I'm a mobile engineer with 6 years of experience who has a particular obsession with building things other developers use β€” SDKs, public APIs, dev tooling. If it ships as a dependency in someone else's pubspec.yaml, Package.swift, or build.gradle, I'm probably more excited about it than the end-user product.

That said, I'm not just a tools person. I've shipped full consumer products, contributed meaningfully to open source, and spent enough time across Android, iOS, and cross-platform to have real opinions about all three β€” and enough humility to know which tool actually fits the job.

By day (and honestly, also by night), I work across:

Things I'm Into

πŸ“¦ SDKs & Public APIs
There's something deeply satisfying about writing an abstraction that other developers actually adopt. Good SDK design is an underrated skill β€” you're making decisions your consumers can't easily undo, so you have to get the ergonomics right. I find that challenge genuinely fun.

πŸ€– AI Products
I build AI-powered things. Not the "we added a GPT call to a button" kind β€” the kind where the intelligence is the product. I'm experimenting constantly; some of it ships, some of it teaches me something worth knowing.

🌍 Open Source
Active contributor. If you've ever had a stranger leave a thoughtful review on your PR at midnight, you know why people do this. That's the energy.


What Makes Me Useful to Your Team

  • Cross-platform without the excuses β€” I can go deep on Flutter for shared logic, drop to Kotlin for Android-specific performance work, and write idiomatic Swift when iOS needs native behaviour. I don't pretend one solution fits everything.
  • SDK design experience β€” I think carefully about public API surfaces, versioning, breaking changes, and developer ergonomics. I've felt the pain of badly designed libraries. I try not to inflict that on others.
  • Full-stack enough to ship β€” Python for AI pipelines and tooling, Bash/CI for automation, TypeScript for React Native or web surfaces. I can own a feature end-to-end without waiting on someone else to unblock me.
  • Open source track record β€” Real commits, real reviews, real collaboration in the open. Easy to verify.

Currently

  • πŸ”¨ Building CircleBox β€” a native flight recorder SDK for mobile apps
  • πŸ“± Going deeper into Desktop apps
  • πŸ€– Tinkering with AI-native experiences
  • 🌱 Contributing to open source whenever I can steal time from my calendar
  • 🀝 Open to collaborating on SDKs, dev tools, or anything that ships as a library

A Few Things About Me

  • πŸ—οΈ I genuinely believe API design is an art form β€” and most people treat it like a first draft
  • πŸ› My bug-to-feature ratio has improved significantly since year 1 (I think)
  • πŸ“– I read PRs the way some people read novels β€” with opinions and margin notes
  • β˜• Fuelled by coffee and the irrational confidence that this time the build will pass on the first try
