Software architecture consulting · EonTech
Architecture advice from people who still build.
We review your architecture, design the target and the path to it, and stay hands-on to build the hard parts with your team. Advisory when you want a second opinion, hands-on when you want it shipped. The decisions and the rationale stay yours.

How an engagement runs
Review, decide, build, then step back
Our work follows a review-to-independence arc. We start by understanding what you have, end with your team able to evolve the architecture on their own, and build alongside you in between.
- 01
Review what exists
We assess the current architecture, the code, the data flows, and the operational reality. The goal is an honest picture of strengths, risks, and the constraints you actually live with.
- 02
Design the target and the path
We propose a target architecture and, just as important, a sequenced roadmap to reach it without halting delivery. Trade-offs are written down, not hand-waved.
- 03
Build it with your team
We do not hand over a slide deck and leave. Senior engineers work alongside yours to implement the first hard pieces, prove the patterns, and transfer the thinking.
- 04
Hand the wheel back
The objective is your team's independence. We leave decision records, reference implementations, and the rationale, so the architecture stays yours to evolve.
What we advise on
Where architecture decisions matter most
From a single subsystem to a whole platform, we bring judgement to the decisions that are expensive to get wrong. Pragmatic patterns, honest trade-offs, and a path you can execute.
-
Architecture review & roadmap
A clear-eyed assessment of where you are, the risks that matter, and a sequenced path forward you can actually execute against your delivery commitments.
-
System design
Designing new systems or major subsystems: boundaries, data ownership, contracts, and failure modes thought through before the first line is committed.
-
Cloud-native patterns
Pragmatic use of services, containers, queues, and managed platforms — the patterns that fit your team and load, not whatever is fashionable this year.
-
Tech-debt strategy
Naming the debt that costs you, deciding what to pay down and what to live with, and folding remediation into delivery rather than a doomed big-bang rewrite.
-
Build-vs-buy
An honest analysis of what to build, buy, or integrate, weighing total cost, lock-in, and the capabilities that genuinely differentiate your business.
Scale & resilience
Designed for real load and real failure
Scalability is not a buzzword on a diagram. We model the capacity your system actually needs, design it to degrade gracefully when something breaks, and make it observable so problems surface before users feel them.
We keep cost in the frame throughout. An architecture that scales on paper but wrecks the cloud bill is the wrong answer, and we will say so.

Advisors who can carry the build
-
Hands-on, not ivory tower
Our architects still ship code, so the designs they propose are ones they would build themselves.
-
Honest trade-offs
We write down what each decision costs as well as what it gains — no silver bullets.
-
One partner
If you want us to build it, the same firm carries the design through to running software and custom AI.
-
Knowledge transfer
Decision records and pairing leave your team able to own and evolve the architecture without us.
Common questions
What technical leaders ask first
-
Is this advisory only, or do you build too?
Both, by design. Many engagements start as a review and roadmap, then continue with our senior engineers building the hard first pieces alongside your team. You can take the architecture and run with it yourself, or have the same firm carry it through to running software — there is no obligation to do one to get the other.
-
How do you approach scalability and resilience?
We model real capacity rather than guessing, design for graceful degradation instead of assuming nothing fails, and bake in observability from the start so problems surface early. We also keep an eye on cost, because an architecture that scales technically but ruins the bill is not a good answer.
-
Will the decisions and rationale stay with us?
Yes. We leave architecture decision records, reference implementations, and the reasoning behind each trade-off. The whole point is your team's independence, so the architecture remains yours to understand, own, and evolve long after we step back.

Tell us the decision in front of you or the system keeping you up at night. We will scope an architecture review in days, then help you decide — and build, if you want us to.
