The pilot works. The rollout is next.
Understand the failure modes, dependencies, and operating costs before you put more devices in the field.
Independent CTO advisory · Energy & IoT
Know what breaks
before you scale.
Your next launch, rollout, or architecture decision needs a clear plan. I help energy and IoT teams find the risks, weigh the trade-offs, and decide what to do next.

Where I work
Energy softwareConnected devicesCloud & edgeEngineering decisions
01 / The right moment
A hard decision.
A lot riding on it.
You already have people building the product. You need an experienced outside view on what happens next.
Your team is stuck on an expensive choice.
Build or buy? Edge or cloud? Keep the platform or change it? Turn competing opinions into a decision with evidence.
Reliability is eating your roadmap.
Get a focused assessment of one critical flow, with a prioritized plan for what to fix first and what can wait.
02 / Work with me
Start with clarity.
Build from there.
A concrete first engagement, followed by ongoing support when it makes sense.

Best fit:
Founders and technical leads in energy or connected products, with a working product, someone who can implement changes, and a specific decision to make.
03 / The output
An opinion is easy.
A useful decision
takes evidence.
You leave with the reasoning, the priorities, and a practical sequence of work. Something your team can challenge, share, and act on.
Illustrative excerpt below. This shows the format, not a client engagement or a completed assessment.
Decision memoExample
Before the next fleet rollout
Question: what should we verify before increasing device volume?
01
Evidence to collect
Reconnect behavior, ingestion capacity, recovery logs, and cost per active device.
02
Decision to make
Whether the current critical path can support the rollout, and which assumptions need a controlled test.
03
Action to assign
Name an owner, define acceptance criteria, and sequence the work against the rollout milestone.

The person on the call
has been close
to the problem.
More about my background I'm Matt. I lead technology at Pstryk, building energy software that connects a digital product to the physical world.
That means working through device integrations, data flows, architecture, and engineering decisions with real operating consequences. My background spans backend development, cloud infrastructure, and technical leadership.
I've worked in software since 2008, and I still read and write code. In a review, I work directly with you and your technical team.

Before we talk
A few straight
answers.
What happens on the first call?
We spend 30 minutes on your product, the decision you're facing, your deadline, and whether I can help. If there's a fit, I send a written scope and fee. The call is for fit and scoping; the technical assessment happens in the paid review.
What does the review cover?
One agreed system or critical flow. We choose the question, evidence, and boundaries before kickoff. The review includes selected documentation and code, a discussion with your technical lead, the written output, and a debrief. A full codebase audit, security assessment, or broader diligence needs a separate scope.
Will you implement the recommendations?
The review gives your team the assessment and action plan. Implementation is separate. Advisory can help your team make decisions and review progress within the monthly time budget.
Can you join as our fractional or interim CTO?
My current focus is scoped technical reviews and advisory alongside my full-time CTO role at Pstryk. If you need someone to run engineering day to day, say that at the start so we can establish whether the engagement is workable.
What should I bring to the call?
Your company or product link, the technical decision you need to make, and your target date. An architecture sketch helps if you have one. Please leave credentials, customer data, and confidential documents out of the booking form.
