who this is for

Three situations, three questions.

We get access to the code, the infrastructure config and the architecture docs, and review them against your specific concern.

“Will this hold up?”TEAMS HITTING LIMITSPerformance, scale, security or maintainability are starting to hurt, and a refactor or rebuild is on the table.
“Should we build it this way?”TEAMS ABOUT TO COMMITA significant build is planned and they want the approach reviewed before they start.
“Is this the right call?”FOUNDERS WITHOUT A SENIOR ENGINEERA technical decision needs pressure-testing by someone with no stake in it.
WE DO✓Review against the concerns you name✓Write findings with severity✓Prioritise by impact and urgency✓Walk through every finding live
WE DON'T✕Implement the fixes (that's a development project)✕Make the decision for you✕Hand over vague, high-level summaries
“The report either tells you exactly what to fix and why, or it is not done.”
what you get

Every finding comes with evidence and a fix.

The report has eight sections. Each finding inside them looks like this.

§3 PERFORMANCE · FINDING 3.2SEVERITY: HIGHPRIORITY 1
N+1 queries on the orders list
EVIDENCE
for order in orders:
 order.customer # 1 query each → 201 queries per page
IMPACTThe list slows down linearly as the number of orders grows.
RECOMMENDATIONLoad customers in one joined query, and add an index on orders.customer_id.

The frameworks behind our reviews.

The standards and published guidance behind how we deliver this service, with every claim linked to its source.

01Architecture you can read

Architecture is documented with the C4 model, context, containers, components and code, so each audience sees the right level of detail [1].

02Security review

Security findings are graded against the OWASP ASVS [2] and the OWASP Top 10 [3].

KEY FACTASVS defines three verification levels, from baseline to high-assurance applications [2].

03Delivery health

Delivery performance is benchmarked with DORA’s four key metrics [4].
