App developer · Knoxville, Tennessee · since 2015: I ship my own apps. I’ll help you ship yours.

Alongside my own apps, I take on a small number of client projects: iPhone, iPad and Mac apps, and Ruby on Rails web apps, for businesses and startups. I work with clients nationwide, and each one works with me directly, from the first conversation to long after launch.

40 real screens from 16 projects, my own apps and clients’ alike.

Some of the companies Lotus has worked with

  • KARM Stores
  • Citus Data
  • NASCAR
  • Eyrus
  • Mogul
  • Croozen

Businesses, not just software

Software that changed the business, not just the screen.

Most of my client work hasn’t been software for its own sake. It’s been part of how a business grew, or how a new one got off the ground, and in a few cases I’ve stayed on for a decade to keep it going. (In the early years Lotus was a small team, so some of these are “we”.)

Custom software for iPhone, iPad, Mac and the web, built in Knoxville.

  • iOS

    iPhone and iPad apps

    From an iPad point of sale in thrift stores across the country to my own Bobara, on iPhone, iPad, Apple Watch and Apple TV.

  • Mac

    Mac apps

    For your business on the Mac, from a small internal tool to something bigger.

  • Rails

    Ruby on Rails web apps and APIs

    Most of Lotus’s client work, some of it carried from Rails 3.2 to 8.1 along the way.

Working with me

You get me, the whole way through.

No account manager and no hand-off: just me, from my desk in Knoxville. I take on only a small number of client projects at a time, so each one gets proper attention. Here’s how that went for OnTrac, KARM’s iPad point of sale.

    Discovery

    Discovery usually turns up requirements, audiences and workflows nobody had explored yet, and sometimes a better answer. I start every project there, my own included.

  2. OnTrac iPad app designs: a PIN login keypad, a sale screen with category buttons, and Sale, Refund and Lock menus

    Design

    Designed around the people using it: for OnTrac, big buttons and a guided checkout, so a volunteer on their first shift can ring up a sale.

    The build

    Well-tested code, because launching matters, but not at the expense of the code you’ll be living with for years afterwards.

    Launch, and after

    I look after what I build once it’s live. I’m still building OnTrac today.

Already have a team? I can join partway through: get a stalled project moving again, or help a team through a tough patch.

Still going

Some client work never ended.

Mogul Wireless since 2015, KARM Thrift Stores since 2016, and their software is still growing.
