7 BRIDGES OF SYSTEMS

I translate device capabilities and native boundaries into responsive product interfaces and reliable services—without losing the constraints that matter at each handoff.

01 // OPERATING FOCUS

The parts that make a product dependable.

01

Signal → state

BLE, APIs, and local persistence become coherent UI—not a collection of race conditions.

02

Policies that hold

Cache, retry, sync, and observability are designed for intermittent networks and long sessions.

03

Product-ready delivery

Native depth where it matters; React Native leverage where it helps.

02 // SELECTED EXPERIENCE

A short record of ownership.

03 // AGENT GOVERNANCE

Agents need a contract, not a vibe.

I built wtcraft to keep parallel agent work scoped, inspectable, and verifiable in plain Git worktrees.
