About

Audit-ready .NET 10 systems. Fixed price. One architect.

Based in the UK. I engineer production platforms businesses can trust under load — same-store audit, two-writer concurrency, and atomic workers — from first call to cutover.

How I work

You talk directly to the person who writes every line. Free technical call, written scope with a fixed price, milestone deliveries with working software, then deployment with documentation. Source code available for purchase.

I reply within one working day. If I cannot help, I will tell you honestly where else to look.

Engineering standards

Same-store audit. Every database write records its audit trail inside the same SQL transaction.
Two-writer concurrency. Row-version predicates prevent silent concurrent mutation.
Atomic workers. Claim-lease pattern with SQL UPDATE OUTPUT — host failure does not duplicate work.
Zero-warning gate. CI rejects a single compiler warning.

Production outcomes

74,200+ LOC modernised to .NET 10 with zero downtime cutover.
£127.4M audited with zero reconciliation discrepancies.
500,000+ jobs daily with zero duplicate dispatches across 8 months.

Technology

.NET 10, Blazor, EF Core, and SQL Server. No stored procedures, views, or triggers — behaviour in C#, state in SQL.
