What I take on
Most of my work is one product, carried from the data model to the screen a technician taps at seven in the morning.
Mobile applications
React Native and TypeScript apps for iOS and Android, built for people using them one-handed, on site, on bad connections.
- React Native
- TypeScript
- Redux
- Firebase
Product interfaces
React and Next.js front ends with a real component system behind them, so the tenth screen costs less to build than the first.
- React
- Next.js
- Tailwind CSS
- TypeScript
APIs and services
Node.js and Express services with typed contracts shared across clients, plus the data models the product workflow actually needs.
- Node.js
- Express.js
- MongoDB
- REST APIs
End to end delivery
One person carrying a product from data model to shipped interface, which keeps the architecture and the UI honest with each other.
- Architecture
- State management
- Git
- Delivery
Built for the long term
I start from the job on the floor, then model it, then ship an interface that still holds at version four.
Discover
Map the real job: who is in the hoistway, the warehouse or the classroom, and what they cannot do today because the software is elsewhere.
- Sit with the operation, not the feature list
- Name the objects: jobs, assets, batches, crews
- Find the moment the current tool drops the thread
Where attention sits
The problems that decide whether a product still holds together after the fourth release.
The portfolio is also an operating system
A custom operating-system-inspired portfolio for exploring projects, skills and professional work.
- A window manager with dock, menu bar and mission control
- A separate mobile shell rather than a shrunken desktop
- A terminal and command palette that actually resolve
- Theme, wallpaper and motion settings that persist
Questions
What kind of work do you take on?
Mobile and web products for operations: service, maintenance, construction, coaching and API tooling. If the user is in the field, that is usually a fit.
Do you only build React Native?
React Native is the core of the field apps. The same TypeScript models also land in Next.js, Node services and this desktop OS.
Can I see the work running?
Launch SundanOS for the interactive portfolio, or open a project case study from Selected work. MASSAED is live on the App Store and Play Store.
How does a project start?
A short brief is enough: the job to be done, who uses it, and when you need it. I will say quickly whether I am the right build.
Is SundanOS just a macOS clone?
No. It is a custom desktop and mobile shell for the portfolio. The Applications folder, arcade and case studies are the product, not a skin over Finder.
Start a project
Tell me what the product has to do and who has to use it. A rough brief is enough to work out whether I am the right build.
