What I'm looking for

I seek a technical leadership role focusing on scalable web applications, mentorship, CI/CD optimisation, strong UX, and measurable performance improvements.

I am a results-driven Senior Web Developer with 7+ years in full-stack development, specializing in Angular, React.js, C# .NET and Azure DevOps. I lead teams, mentor junior developers, and deliver scalable, high-performance web applications using Agile practices.

At my current role I spearheaded migrations from AngularJS to Angular 12+, improving performance by 40% and reducing bundle size by 25%, implemented SSR and lazy loading to boost Lighthouse scores above 90, and achieved 95%+ test coverage to cut production bugs significantly.

I value clean code, UX excellence and continuous learning, and I seek opportunities where I can drive technical direction, optimize CI/CD pipelines, and grow engineering teams while delivering measurable business impact.
