What we build

Six things we do well, from a first marketing site to a multi-platform product. Every engagement is led by a senior engineer who has shipped this before.

  • Website & Web App Development

    Custom websites and web applications built with React and Next.js. Fast, accessible, and built to rank — by engineers who've shipped for Fortune 500s and funded startups.

Why teams hire us

A small senior team with a large-company track record

Taatgen Development LLC was founded in 2023 by Mike Taatgen after a decade of building production software inside companies like Southwest Airlines and for funded startups. We bring that experience to every project — no matter where the client is.

  • Senior engineers, start to finish

    The person on the discovery call is the person writing the code. No hand-off to a junior team after the sale.

  • Dallas roots, clients anywhere

    We're based in Irving, Texas and meet DFW clients in person — and we've delivered for clients across the US and abroad, mostly remote, for years.

  • Enterprise discipline at agency speed

    Testing, CI/CD, accessibility and performance budgets come from our Fortune 500 work. Weekly demos on a staging URL come from our startup work.

  • Straight answers

    We'll tell you when a template is enough, when headless is overkill, and what a project will really cost before you commit.

Testimonials

What people say about working with us

  • Mike is an absolute joy to work with. He is not only highly skilled, but also very personable and able to easily build rapport with his clients. Once he takes on a project, he invests himself fully in ensuring that it meets the highest standards of quality, and his attention to detail is unparalleled.

    Adeeb A.React Engineer
  • We developed the front end for a suite of media management apps together. Mike's technical skills and keen eye for detail were evident from the start, and his collaborative spirit and excellent communication made working with him a pleasure. I wholeheartedly recommend him as a highly skilled React developer and valuable team player.

How we work

From first call to launch, in four steps

  1. Discovery

    A focused session to align on goals, scope, integrations and timeline. You leave with a written plan and a real quote.

  2. Design

    We work from your Figma or produce the UI ourselves. Every screen is reviewed with you before we build it.

  3. Build

    Weekly demos on a staging URL. Tests, CI/CD and performance checks are part of the work, not extras.

  4. Launch & support

    Analytics, SEO and launch checks — then a support window and an optional retainer for what comes next.

Stack

Tools we reach for

A deliberately boring, well-supported stack — so the product is fast to build, easy to hire for, and still maintainable in five years.
