A studio for
carefully made
software.

Modern Logic Tech is the independent practice of Matthew Choo. I design and ship privacy-first apps — and partner with founders building modern software that respects the people using it.

§ 02 — Practice

Two sides of the same studio.
Apps I make. Software I help others make.

A / 01

The product studio

Five apps in market, each built around a single principle: your data stays on your device. No tracking, no telemetry, no surprises in the terms.

A / 02

The independent practice

Direct engagement with founders and small teams. MVPs, full-stack builds, and modernization — done by the person actually writing the code.

A / 03

One developer

No account managers, no offshore handoffs. You work directly with me from first call to final commit. Small by design.
