One builder.
The whole technical picture.

I’m James Thullbery. I build and maintain custom software for real businesses, from the first idea to the systems people use every day.

Built for work that actually happens.

I build close to the people using the software, and stay involved as the systems evolve.

Live shop software

The software behind my own bike shop.

I’ve owned and operated Tehaleh Bike Shop since October 2024. In summer 2026, I began building localbike.shop to bring customer records, bikes, jobs, scheduling, inventory and invoicing into one place.

Tehaleh Bike Shop is its first and currently only customer. I’m developing the software with the goal of serving other independent bike shops over time.

Active development · Beta

A platform for private ride services.

DDS connects booking, dispatch, driver and rider experiences for private ride services. Freedom Rides is its first client.

The platform is in active development and beta, with drivers on the road through Freedom Rides. Expanding to other independent drivers and operators is a future goal.

What we can build together.

Custom applications

Turn a business need or product idea into software people can use, with a clear first release and room to grow.

Connected operations

Bring workflows, data and integrations together, so the business spends less effort moving information around.

Agentic workflows

Bring practical experience with AI agents into development, with clear ownership of decisions, review and delivery.

More capacity.
Clear ownership.

AI agents expand what I can take on as an individual. My job is to understand your business, choose the right architecture, direct the work and verify what ships.

You have one person to talk to and one person accountable for the technical outcome.

A builder, and an operator.

I still work at Fountain, where I’ve been instrumental in helping the team adopt agentic development over the past 12–18 months.

Outside that work, I develop independent software and run my own bike shop. That combination keeps me close to both the engineering and the everyday business decisions software needs to support.

For independent projects, we agree on scope, timing and ongoing support before work begins.
