DK.

David Knetemann

Founder & Software Engineer — The DK Studio, Antwerp, Belgium

I build production-grade web software from Antwerp: marketing sites, SaaS products, e-commerce platforms, and the integrations that hold them together. My stack of choice is Next.js, TypeScript, and Node.js — deployed on Vercel, measured against Core Web Vitals, and wired for technical SEO from day one.

Over the past decade I have shipped event-ticketing platforms with real-time inventory, staffing tools, cross-border commerce, and dozens of founder-led products. The throughline: senior engineering without agency overhead, honest scoping, and software that keeps working long after launch.

I write daily about Next.js, technical SEO, and shipping software for Belgian SMEs and international founders on the engineering blog.

How I work

Production-grade delivery

Ticketing platforms, SaaS products, staffing tools, and cross-border e-commerce — shipped, monitored, and maintained in production.

Senior, no handoffs

You work directly with the engineer who scopes, architects, and builds your product. No account managers, no junior delivery.

Performance & SEO baked in

Core Web Vitals, structured data, and indexability are part of every build — not an afterthought or an upsell.

Honest scoping

Discovery before fixed quotes. Trade-offs explained in plain language, with realistic timelines and budgets.

What I build

  • Web Development

    Marketing sites and landing pages on Next.js — responsive, fast, and wired for leads.

  • Web Applications

    Custom SaaS, dashboards, and internal tools — typed, tested, and maintainable.

  • E-Commerce & Platforms

    Storefronts and multi-sided platforms with secure checkout, inventory, and admin tooling.

  • Integrations & SEO

    Third-party APIs, webhooks, analytics, and technical SEO for traffic and tooling.
