Engineering & Consultancy

Technical architecture review, an honest second opinion.

Is your architecture ready for what's next — the next 10x of scale, the next audit, the next acquirer? We review it independently, find what's fragile, and hand you a prioritized roadmap, not a lecture.

The assessment

Every dimension that decides whether it holds

We score your architecture across the dimensions that actually break under pressure — weighted by where reviews most often surface real risk.

Security & compliance

Whether the architecture protects PHI and stands up to an audit — the gap that ends companies.

Critical

Scalability & performance

Whether the design survives the next 10x of load, or quietly falls over at it.

High

Reliability & resilience

What happens when a dependency fails — graceful degradation or a 3am outage.

High

Maintainability & tech debt

Whether the team can still ship quickly, or every change now risks three regressions.

High

Interoperability

How cleanly the system exchanges data with the EHRs and partners it has to talk to.

Medium

Cost & efficiency

Whether the cloud bill scales with value, or just scales.

Medium
Why AST

Reviewed by people who've built and rescued these systems

An architecture review is only as good as the scars behind it. Ours come from years of designing — and fixing — clinical systems at scale.

17+
years architecting healthcare systems

We've designed and rescued enough clinical architectures to know where the bodies are buried.

6
dimensions scored

A structured assessment across the dimensions that actually break — not a vague “looks fine.”

0
stake in the answer

We're independent. If the architecture is sound, we'll tell you that and save you a rewrite.

1
ranked roadmap you can fund

Findings prioritized by impact and effort, in a form your board can actually approve.

The engagement

How the review works

From understanding the system to a board-ready roadmap — a structured assessment that ends in a plan, not a verdict.

A team reviewing an architecture
01Discovery

We learn the system, the business context and where you're trying to go — because an architecture is only “good” relative to what you're asking it to do.

  • Architecture walkthrough
  • Code & infra review
  • Team interviews
  • Goals & constraints
02Assessment

We evaluate the architecture across every dimension that matters, probing the assumptions that hold until exactly the moment they don't.

  • Dimension-by-dimension
  • Failure-mode analysis
  • Bottleneck identification
  • Risk surfacing
03Findings & scoring

We score what we find and rank it by impact and effort — so you can tell the load-bearing problems from the cosmetic ones at a glance.

  • Scored findings
  • Impact × effort
  • Quick wins vs big bets
  • Evidence & examples
04Roadmap & readout

You get a prioritized roadmap and a readout that works for both engineers and the board — not a document that dies in a drive.

  • Prioritized roadmap
  • Engineering detail
  • Executive readout
  • Decision support
What we examine

The full surface of the architecture

Architecture & design

The shape of the system — and whether it fits the problem it's solving.

  • System decomposition
  • Boundaries & coupling
  • Patterns & anti-patterns
  • Fit for purpose

Scalability & performance

Where the design holds under load and where it quietly gives way.

  • Bottlenecks
  • Data & query load
  • Caching & async
  • Load headroom

Security & compliance

Whether PHI is protected and the architecture is audit-defensible.

  • Threat surface
  • Access & encryption
  • HIPAA posture
  • Audit readiness

Reliability & operations

How the system behaves when something inevitably fails.

  • Failure modes
  • Observability
  • Recovery
  • Operability

Data & integration

How cleanly data flows within the system and out to partners.

  • Data model
  • Integration patterns
  • FHIR / HL7
  • Consistency

Code & tech debt

Whether the codebase still lets the team move, or fights them.

  • Code health
  • Test coverage
  • Tech-debt hotspots
  • Delivery friction
Who it's for

When you need to know what you're standing on

Straining under growth, heading into due diligence, or newly responsible for a system you didn't build — the question is the same: will it hold?

Examining a codebase

Growth is straining the system

Usage is climbing and the architecture that got you here is starting to creak. We find what'll break at the next order of magnitude — before your customers do.

  • Scale bottlenecks
  • Headroom analysis
  • Prioritized fixes
  • Confidence to grow

Raising or being acquired

An investor or acquirer is about to put your architecture under a microscope. We give you the same view first — so there are no surprises in the data room.

  • DD-grade review
  • Risk disclosure
  • Remediation cost view
  • Stronger position

New to a system you didn't build

You've taken over an architecture nobody fully understands and decisions are due. We map it, score it and tell you what's safe, what's fragile and what's urgent.

  • System map
  • Risk inventory
  • What to fix first
  • A clear mandate
The deliverable

An opinion, or a plan you can run

The value of a review is entirely in what you can do with it the next morning. Most reviews fail that test.

What you often get
A vague opinion
“Looks fine” or “rewrite it”

A reviewer who either rubber-stamps the architecture or recommends throwing it all away — neither of which tells you what to actually do on Monday.

  • No real scoring
  • Binary verdicts
  • No prioritization
  • Hard to action
What we deliver
A ranked roadmap
Specific, scored, sequenced

Concrete findings scored by impact and effort, sequenced into a roadmap your team can execute and your board can fund — with the evidence behind each one.

  • Scored findings
  • Impact × effort ranking
  • Sequenced roadmap
  • Board-ready readout

How we assess

Review principles we work by

The convictions that make a review worth more than the opinion of the loudest person in the room.

Mapping a system on a whiteboard

Independent and honest

We have no stake in the verdict. If your architecture is sound, that's what we'll tell you.

Score, don't vibe

Findings are scored against explicit criteria, not delivered as gut feel dressed up as expertise.

Rank by impact

We separate the load-bearing risks from the cosmetic ones, so effort goes where it matters.

Pragmatic, not purist

We judge the architecture against your context and goals, not a textbook ideal you don't need.

Roadmap, not rewrite

We look for the incremental path first. A full rewrite is a last resort, not an opening bid.

Speak to the board

The readout lands for engineers and executives alike, so the work actually gets funded.

Questions

Architecture review FAQ

Are you just going to tell us to rewrite everything?

Almost never. A full rewrite is the most expensive and risky option, and it's rarely the right one. We look for the incremental path — the targeted changes that buy the most resilience for the least disruption — and only recommend a rewrite when the evidence genuinely demands it.

How long does a review take?

Typically a few weeks, scoped to the size of the system and the questions you need answered. We agree the scope up front so you get a focused assessment rather than an open-ended audit.

Do you need access to our code?

Yes — a meaningful review is white-box. We look at the architecture, the code and the infrastructure, and we interview the people who run it. A review based only on diagrams misses exactly the problems you're paying us to find.

Is this suitable for investor or acquirer due diligence?

Yes. We deliver technical due diligence to the standard investors and acquirers expect — an honest read on architecture risk, remediation cost and team capability — whether you're the one being assessed or the one doing the assessing.

Can you fix what you find?

We can. The review ends in a roadmap, and our engineering pods can execute it — or we'll hand it to your team in a form they can run with. The assessment and the fix can live under one roof, or not, as you prefer.

Let's look under the hood

Confident your architecture survives the next 10x?

Tell us what's keeping you up at night about the system. We'll review it honestly and hand you a roadmap you can act on — and fund.
