About

Built on the standards of critical environments.

CriticalBits is the independent practice of a senior firmware engineer specialized in embedded systems and BLE connectivity for connected devices. Background in mission-critical development environments — where failures in design or testing carry real consequences.

Deliverables-Based

Clear scope definition, structured timelines, and regular progress updates. You always know what you're getting and when.

code

Modular & Documented Code

Production-oriented firmware — designed to be maintained by someone other than the original author.

target

Async & Flexible

Communication via email or messaging platforms (Slack, Teams). Regular progress updates at each milestone, so you have visibility without constant check-ins.

Approach

Structured planning from day one, rigorous testing practices, and architecture decisions made for the long term, not just the prototype. We work with teams building connected and embedded products across industrial automation, smart infrastructure, and consumer electronics.

Equally comfortable joining a project from day one or stepping in to solve a specific technical challenge on an ongoing one.
