Problems I solve

  • 01

    Slow pages drive customers away

    53% of mobile users abandon pages that take more than 3 seconds to load. 100ms of delay costs you an average of 1% in revenue.

    Solution

    I identify the specific technical bottlenecks causing slow load times and fix them systematically.

  • 02

    Poor Core Web Vitals hurt SEO rankings

    Google uses Core Web Vitals as a ranking factor. Slow pages rank lower and receive less organic traffic.

    Solution

    I optimise rendering, reduce JavaScript bundle size, and improve database queries to boost your rankings.

  • 03

    Accessibility is mandatory but you don't know where to start

    Since 2026, implementing accessibility standards is legally required for many websites.

    Solution

    I conduct an accessibility test with you and help you make your website legally compliant.

  • 04

    Generic optimisation advice doesn't help

    You know all the tips about conversion and performance optimisation, but none of them apply to your specific situation.

    Solution

    I dive deep into your actual code and architecture to deliver actionable, prioritised fixes.

Will the Website Audit help you?

Yes, if you...

  • Know your website is slow – but don't know exactly where the problem lies
  • Are facing a redesign or relaunch and don't want to carry technical debt into the new project
  • Fall under the EU accessibility obligation since 2026 and need legal compliance
  • Want concrete, prioritised measures – not a generic checklist

No, if you...

  • Are still building your website from scratch – the audit comes after that
  • Prefer general optimisation tips over deep code analysis

How I help

I'm Nils – Senior Fullstack Developer specialising in modern web applications and performance optimisation. For years I've been building products for startups and mid-sized companies that are used by real users every day.

With a Performance Audit you can:

  • Save revenue: Amazon found that 100ms of latency costs 1% in revenue. I reverse that loss.
  • Boost SEO & GEO: Core Web Vitals are a ranking factor and fast pages are also crawled better by LLMs.
  • Reduce infrastructure costs: Optimised code consumes fewer resources.

Testimonials

„There aren’t many true full-stack developers. Fewer still can take on deeply complex problems and genuinely solve them. Nils is both, and more. He brings technical depth, clarity of thought, and a calm, reliable presence to every project. A highly respected and recommended addition to any team. And when he’s not coding, he’s out training for triathlons; a true embodiment of work hard, code hard, play hard. On all fronts, Nils is a machine.“
