I build the systems companies bet their business on.
Two decades shipping Microsoft-centric platforms for organisations that cannot afford downtime. Now AI-leveraged: one senior engineer, the output of a small team, held to a production bar that does not move. Distributed services, cross-platform clients, real-time, secure by default.

Senior velocity, multiplied - without the slop
The AI-era market is bimodal. Generalists who prompt their way to half-working code, and senior engineers who wield AI agents on codebases with doctrine, contract tests, and explicit review gates. I operate in the second bracket, in production, right now.

Shipping velocity on a real codebase
Live production work across a 200k+ line Uno / .NET 9 cross-platform codebase with automated regression coverage. Output is measured in merged, tested features — not lines of code or vibe-coded demos.
0
Tolerance for hallucinated defects
AI agents ship what I review, not what I glance at. Contract tests, explicit architectural doctrine, and deliberate review gates mean the work that lands on main has been designed, not autocomplete-hoped.
1 : N
One senior, the output of a team
Teams migrating off Xamarin, absorbing AI into production .NET services, or closing out a stalled cross-platform rollout see the compound effect inside weeks. One day rate, no ramp-up, no headcount overhead.
Profile
Depth across the stack, and across the lifecycle
From architecture and code to pipelines and production support: maintainable systems, clear boundaries, and outcomes that register on business metrics.
Senior Software Engineer with over twenty years in Microsoft-centric application development, specializing in enterprise solutions that drive real business transformation. My expertise spans the full software development lifecycle: architecture, implementation, deployment, and long-term maintenance.
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.

Principles
Philosophy
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.
