About
Focused on solutions that work long-term
I am a senior full-stack developer with a strong focus on practical, business-oriented web solutions. My primary stack is C#, ASP.NET MVC / ASP.NET Core, SQL Server, JavaScript and jQuery, but I am comfortable across the full delivery chain, from database design to production deployment.
I have spent years building and maintaining content-heavy websites, custom CMS systems, data integrations and reporting pipelines. That has meant working closely with editorial teams, managing servers and picking up enough about technical SEO to make it part of the process rather than an afterthought.
I tend to prefer simple, well-structured systems that are easy to read and change. Not always the most exciting approach, but it tends to hold up well over time.
Full-Stack Delivery
From initial architecture through development, testing and production launch, including server configuration and post-launch support.
Data & Reporting
API data pipelines, structured data processing and custom .NET 8 reporting systems, with AI where it genuinely adds value over heavy third-party tools.
Technical SEO & Performance
Core Web Vitals, structured data, clean redirects and page speed treated as part of the work, not something added at the end.
Operations & Infrastructure
Windows Server, IIS, SSL, backups, deployments and production monitoring. Happy to handle the operations side when there is no dedicated ops team.

Working Style
How I approach work
How I tend to think about work, for better or worse.
Practical solutions before unnecessary complexity. I reach for the simplest approach that genuinely solves the problem.
Server-rendered HTML when it makes sense. Not every project needs a JavaScript framework and the overhead that comes with it.
Strong focus on performance, maintainability and technical SEO as first-class concerns, not afterthoughts.
Comfortable with both development and production operations. I can take a project from code to running server without gaps.
I try to understand how people actually work before jumping to a solution, which usually saves a lot of back and forth later.
Long-term preference for systems that are easy to understand, easy to maintain and easy to hand over when needed.
There is rarely one right way to build something. What matters is picking an approach the team genuinely understands, can maintain long-term, and won't regret six months later.
