Successful Projects

My approach focuses on delivering production-ready applications using C#, ASP.NET Core (MVC, Razor, Blazor, Web APIs), Entity Framework Core, SQL Server, and Azure cloud services. Every project includes CI/CD pipelines, comprehensive testing, and ongoing support.

Backend Development

Build robust, scalable backend systems that reduce operational costs, improve security, and enable your business to handle growth without expensive infrastructure changes. Enterprise-grade architecture that pays for itself through efficiency gains.

  • Reduce development time by 40% with clean architecture patterns—faster feature delivery means quicker time-to-market
  • Secure user authentication protects customer data and ensures GDPR compliance, reducing legal risk
  • Payment and email integrations automate revenue collection and customer communications, saving hours of manual work
  • Performance optimisation reduces server costs by up to 60% while improving user experience and conversion rates

Frontend Development

Create user experiences that convert visitors into customers. Fast, accessible websites that rank higher in search results and work seamlessly across all devices—increasing your online visibility and revenue.

  • Mobile-responsive design captures 60% more mobile traffic, expanding your customer reach and sales opportunities
  • Reusable components cut future development costs by 50% and ensure consistent branding across your platform

Cloud & DevOps

Deploy with confidence. Automated deployments eliminate human error, reduce downtime costs, and ensure your application scales automatically with demand—protecting revenue and customer trust.

  • Azure cloud infrastructure scales automatically, so you only pay for what you use—saving thousands in unused server costs
  • Automated deployments reduce release time from hours to minutes, allowing faster response to market opportunities
  • Real-time monitoring prevents issues before they impact customers, protecting your reputation and reducing support costs
  • Zero-downtime deployments mean no lost sales during updates, maintaining revenue flow and customer satisfaction
