Software-defined physical products

Your engineering system is the bottleneck.

Find and eliminate the engineering constraints slowing your development, integration and release for software-defined physical products.

Constraint

02 / 11

Your team isn't slow. Your system is.

Good engineers lose enormous amounts of time to systems that were never designed to scale.

  • 01

    Slow CI

    A 30-minute build turns every iteration into a context-switching exercise.

  • 02

    Manual hardware testing

    Engineers become the glue between firmware, test benches and lab equipment.

  • 03

    Fragile integration

    Failures appear late because the real system isn't being tested continuously.

  • 04

    Release bottlenecks

    One or two people become the only ones who know how to produce a reliable release.

  • 05

    Developer environments

    Every engineer spends hours recreating a slightly different version of the same system.

  • 06

    Infrastructure debt

    Tooling accumulated around the product becomes harder to maintain than the product itself.

These aren't individual developer problems. They're systems problems.

Instrumentation

03 / 11

Where does the time disappear?

Most teams know something's slow. Few know exactly why. Your workflow gets instrumented, baselined, and the constraints that actually matter get named.

The product

04 / 11

Four weeks. Not consulting. A defined product.

Start with a 4-week assessment

The Engineering Bottleneck Assessment is a focused four-week engagement to identify, measure and attack one engineering constraint.

  1. 01

    Observe

    Get a map of your workflow from commit to integrated system: tools, infrastructure, test systems and handoffs included.

  2. 02

    Measure

    Get a quantitative baseline: build times, test duration, failure rates, manual steps, release frequency, engineer-hours, measured from your pipeline.

  3. 03

    Prove

    Get a targeted improvement against your most valuable bottleneck. The goal isn't a presentation. It's evidence.

  4. 04

    Plan

    You receive a technical roadmap showing what to fix, what it will take and what should happen next.

You leave with

  • Current-state engineering architecture
  • Bottleneck analysis
  • Quantitative baseline
  • Working proof-of-concept
  • Prioritized remediation plan
  • Implementation estimate

What happens next

05 / 11

The report isn't the end.

When the solution's worth implementing, it gets put into production. You don't carry the engineering load alone.

  • 01

    Fix

    The specific improvement from your assessment, implemented to prod with measured before/after.

  • 02

    Modernize

    Your underlying engineering infrastructure, redesigned so the constraint can't return in the same form.

  • 03

    Embed

    An engineering partner embedded with your team at the hardware/firmware/infrastructure boundary.

What we work on

    • Cross-compilation
    • Reproducible builds
  • Verification

Why us

08 / 11

Built at the system boundary.

Software meets the physical world. That's where this work lives.

Our engineering backgrounds span embedded Linux, RTOS, C/C++, Go, Python, CI/CD, hardware integration and production systems.

We've built and operated systems where firmware, operating systems, hardware, networking and engineering infrastructure all have to work together.

That perspective matters because the hardest engineering bottlenecks rarely belong to a single layer. The problem is usually between them.

Layers we operate across

  • Embedded Linux
  • RTOS
  • C / C++
  • Go
  • Python
  • CI/CD
  • Hardware integration
  • Production systems

Qualification

09 / 11

Who this is for

Probably a fit

  • Your product is already technically real.
  • Your engineering team is growing.
  • Hardware and software are increasingly coupled.
  • Testing requires physical equipment.
  • CI is becoming painful.
  • Releases depend on tribal knowledge.
  • Engineers spend too much time maintaining tooling.
  • You know something is inefficient but haven't quantified it.

Probably not

  • You're looking for a general-purpose developer.
  • You need someone to fill a permanent headcount position.
  • You only need a simple CRUD application.
  • You're looking for the cheapest contractor available.

Investment

10 / 11

Clear packages. No open-ended retainers to start.

USD for US teams. EUR for EU teams. Start with the four-week assessment. Fix and Embed follow only when the evidence says they should. One price for startups and mid-market.
