Production .NET 10 systems, delivered start to finish by one architect

Your .NET Framework monolith is slowing every deployment. Pages take seconds. Audit trails are unreliable. I refactor it to a zero-warning .NET 10 Blazor platform — your team maintains clean code, your users get sub-second pages, and cutover happens with zero downtime. On the case-management rebuild that meant 74,200+ LOC moved without a day of downtime.

Commission errors cost clients real money. Bank reconciliations that do not balance are a compliance risk. I build transaction pipelines protected by proved two-writer SQL concurrency — your numbers balance at peak load, every time. Same-store audit means every mutation has a permanent, verifiable record in the same transaction.

Campaign automation that duplicates? Document ingestion that drops files? Background queues that lose jobs on restart? I build atomic claim-leasing, idempotency keys, and three-category lease recovery so every job runs exactly once — even through host failure.

Stalled delivery? Mysterious deadlocks? Security gaps you cannot quantify? I deliver a written report with prioritised fixes, a remediation roadmap, and executable next steps. Typical turnaround: two weeks. If we proceed to a build, the audit fee is credited.

Enterprise Case Management and Advisor Workflow System

Outcome: Page loads from seconds to milliseconds. Advisor workflows from 2 days to 20 minutes. 74,200+ LOC, zero downtime cutover.

High-Volume Financial Commission and Multi-Store Ledger

Outcome: £127.4M audited with zero reconciliation discrepancies. Bank reconciliation from 3 days to real-time.

Real-Time Fleet and Asset Telemetry Platform

Outcome: 150ms per packet on tablet hardware. 99.999% uptime since deployment.

Multi-Tenant SaaS Engine with Impersonation and Audit

Outcome: Third-party security audit: zero findings. Impersonation adopted as an internal reference pattern.

Distributed Worker Queue with Outbox Recovery

Outcome: 500,000+ jobs daily. Zero duplicate dispatches across 8 months of production.

Egress-Controlled Document Ingestion Microservice

Outcome: 2.3 million documents ingested. Zero SSRF incidents. Pattern adopted fleet-wide.

We talk for 30 minutes about your project, your stack, and what you need. If it fits what I do, I write a one-page scope document with a fixed price. If it does not, I tell you where else to look.

Before I write code, I define the data model, API contracts, audit schemas, and UI layout. You review and approve every spec. No surprises at delivery.

I build to the approved spec — .NET 10, direct EF Core LINQ, same-store audit, zero build warnings. You see working software at every milestone.

I deploy to your infrastructure and train your staff. Full source code, repository history, and documentation are available for purchase at an agreed fee. The compiled system is licensed for perpetual use with no ongoing commitment.
