Production-grade AI software delivery
I help founders, SMEs, and enterprise teams turn AI-generated prototypes, legacy .NET systems, and messy product ideas into secure, scalable, launch-ready software. AI can generate code. My job is making sure the product actually works in the real world.
A public-site assistant running through a Worker and lightweight RAG. It is the small version of the same principle I use on client work: AI with boundaries, logs, and human judgement.
One senior, the output of a team: architecture, rescue work, CI/CD, test strategy, performance, cloud deployment, and AI-assisted delivery held to a production bar.
Productised senior engineering for teams moving fast with AI, living with legacy .NET, or trying to get a serious product over the production line.
For apps built with Cursor, Claude, Codex, Lovable, Bolt, Replit, freelancers, or agencies. I review architecture, security, data, deployment, scalability, test coverage, and likely AI-generated weak spots, then give you a practical 30-day rescue plan.
A focused sprint to harden the highest-risk parts of a half-built or AI-built app: authentication, APIs, database design, deployment, observability, performance, and the code paths that must not fail at launch.
Modernise WinForms, WPF, ASP.NET MVC, WebForms, WCF, SQL Server-heavy workflows, and desktop systems without throwing away the business logic that still earns money. AI accelerates the work; senior judgement controls the risk.
Senior technical judgement for founders building with AI tools, freelancers, or a small product team. Architecture reviews, roadmap risk, PR review, vendor sanity checks, and a clear view of what should be automated, rebuilt, or left alone.
For serious MVPs that need clean architecture, cloud deployment, security, tests, maintainability, and realistic product trade-offs from day one. Not a demo generator: a real product engineering path.
Funded founders with AI-built prototypes, SMEs with legacy .NET systems, agencies needing senior rescue capacity, and teams that need production-grade delivery without hiring a full team.
public class EnterpriseService

private readonly IDistributedCache _cache;
public async Task<Result> ProcessAsync(Request req)
{
var cached = await _cache.GetAsync(req.Key);

await _cache.SetAsync(req.Key, result);
return result;
}
}
Basic development is getting cheaper. Real engineering judgement is getting more valuable: architecture, security, testing, deployment, product trade-offs, and knowing when generated code is confidently wrong.
I use AI agents to accelerate design, implementation, review, and regression coverage, but the accountability stays human. No blind merges, no magic architecture, no fake productivity that becomes tomorrow's outage.
Old WinForms, WPF, ASP.NET, WCF, SQL Server, and desktop workflows usually contain valuable business logic. The right move is often gradual extraction and modernisation, not a heroic rewrite.
Two decades of production delivery plus AI-assisted engineering means a leaner path from messy idea to hardened release. Useful for audits, rescue work, modernisation, and focused product builds.
AI-native chat
Streamed chat over a small RAG path: Worker, retrieval on these public pages, and the usual production care around boundaries. Ask about stack, career shape, and fit. For IR35, SOW, or anything binding, use email or Offers.

From architecture and code to pipelines and production support: the parts that decide whether a fast prototype becomes a dependable product.
I help businesses move fast with AI without building fragile software. That means auditing AI-generated code, rescuing half-built products, modernising legacy .NET, and designing systems that remain understandable after the first launch.
I have delivered complex applications for financial services, healthcare, e-commerce, gaming, and industrial automation. Consistently meeting demanding deadlines while holding the line on code quality, performance, and operational resilience is not optional in those industries. It is the baseline.
Performance and scale: legacy modernization, profiling, multithreaded architectures, and database tuning, including scaling datasets from roughly 2,000 to 16,000+ records while preserving responsiveness.

How I approach complex systems, teams, and production pressure.
Clarity beats cleverness, every single time. I design systems with explicit boundaries, testable seams, and architectures the next engineer can reason about at 2 a.m. without heroics. If your codebase needs a hero, your codebase has a problem.

UK eligibility & professional
Right to work. British citizen: indefinite right to work in the United Kingdom; no visa sponsorship required for UK engagements, now or in the future.
Security vetting. Not currently holding national security vetting at Security Check (SC) level; happy to work with an employer to apply through United Kingdom Security Vetting (UKSV) if a role requires it. In an earlier role, completed pre-employment screening consistent with the government’s Baseline Personnel Security Standard (BPSS) (many years ago). BPSS is pre-employment screening; it is not a live “clearance” you carry, and any future BPSS or higher national security vetting would follow the employer’s process afresh under current Cabinet Office guidance.
