Shan Ul Haq. I take hardware products from idea to production, and lead the teams that build them.

Let’s talk

Hands-on CTO and product architect. I work best where physical hardware meets intelligent software.

How I can help

Three ways to work together, depending on what your product needs now.

Fractional CTO

Part-time technical leadership: architecture, team direction and delivery, from first prototype to production.

Hands-on product builds

I design and build the product with you, from the first schematic to units ready for production.

Consulting and technical reviews

A senior second opinion on your architecture, design or production plan, with clear risks and next steps.

Senior judgment,
at agent speed.

I run AI agents across firmware, backend and CAD work, and I stay accountable for the result. Work that once needed a bigger team now moves far faster.

  1. I set the direction

    Architecture, constraints and what good looks like.

  2. Agents build in parallel

    Firmware, backend and tests, moving at the same time.

  3. I review and prove it

    Every change is checked by me, then tested on real hardware.

From idea to production

The same five stages, whatever the product.

  1. Understand

    Goal, users, constraints, risks and success criteria.

  2. Architect

    The complete system, from hardware to cloud to user experience.

  3. Prototype

    Structured prototypes that validate assumptions quickly.

  4. Engineer

    Reliable hardware, firmware, backend and product logic.

  5. Scale

    Manufacturing, deployment, monitoring, updates and support.
