Services

Native apps

We develop custom iOS and Android applications using Kotlin, Swift, Objective-C and Java. Our approach means that overall, the application delivered is yours, and is completely scalable and testable.

AI-assisted development

We use AI tools to move faster without cutting corners — every line is reviewed, tested, and owned by an experienced engineer. You get the speed of AI-assisted development with the judgment and accountability of someone who's shipped production software for two decades.

Web development

We work with Python, Rails and Golang websites and their associated APIs, mainly geared towards mobile applications using methodologies such as test-driven development.

Entrepreneurship

We have worked with virtual, as well as digitally integrated physical products that have launched in Fortune-500 companies and startups. This variety of experience can help your idea blossom into a reality.

Leadership

How do you make a team gel? How do you make it high-performing? These oft sought-after traits are sometimes elusive. We have experience that can help a team develop together.

Mark Schisler, Principal

Mark brings two decades of software leadership to every engagement — helping founders and product teams turn ambitious ideas into software people actually rely on. He's led engineering for products used by millions, including apps recognized by the White House as a Champion of Change and a connected-home product ranked highest in customer satisfaction by J.D. Power, and has partnered with brands like Emerson and MLS club St. Louis CITY SC to bring their products to life.

Clients bring Mark in when they need more than a developer — they need a partner who can own outcomes end to end:

  • Native iOS, Android, and Linux applications built to last, not just ship
  • Web platforms and APIs in Python, Go, and Ruby on Rails that scale with your business
  • Hands-on leadership — Extreme Programming, Lean, and Test-Driven Development practices that keep teams shipping quality, fast
  • Expert-driven, AI-assisted development — modern AI tooling accelerates the work, but every decision is still made and owned by an experienced engineer

Whether you're a startup building your first product or an established team raising the bar, Mark works alongside you to deliver software that's built right the first time.
