No nonsense.

Mallowfields builds digital tools and methods for engineering and governance. We solve problems in decision-making, knowledge-sharing, and collaboration.

We self-fund our product development through relevant service work. We offer our clients in business and government the same attributes we bring to bear on our own projects: technical depth, mature skill, efficient self-management, and a no-nonsense approach to building digital systems that actually work for the people who use and support them.



Mallowfields works as a team. Collaboration is a practical requirement to build quality software that solves more actual problems than it creates.

We are experienced masters of our trades. We are more than the sum of our parts, but our parts are formidable too. Working with us means engaging our actual, specific, human selves, with our accumulated histories of skills, knowledge, and perspectives.

Kendell Joseph

Co-CEO, Principal Software Engineer Kendell is Mallowfields' inventor, ambassador, professor, recruiter, and coach. He is by trade a geographic information systems (GIS) professional, an expert JavaScript developer, and a restless reformer in the practice of teaching computers and science to kids and adults. He has the unique talent of turning vague-sounding technical ideas into vivid, specific, working prototypes, and this talent is the foundation of several of Mallowfields' original software products.

Mallowfields was founded in large part to bring Kendell's prototype products to market as robust, scalable, useful software for government and industry. He drives Mallowfields as a company as he makes connections, solves problems and casts a vision of what could be. At the same time, his authentic kindness and interest in people brought together and sustains the group of individual humans that are the employee-owners of Mallowfields.

Joshua Honig
Principal Software Architect

Joshua Honig

Principal Software Architect Joshua is Mallowfields' lead engineer, with primary responsibility for solution architecture and backend implementation: He draws diagrams, explains things, writes code, and guides the engineering work of the rest of the team. Joshua is also the primary architect of Mallowfields' governing structure, drawing many of the blueprints for the foundations of our corporate republic. Actually laying those foundations is, by definition, the work of the whole team.

Joshua's hostility to nonsense is neither guarded nor a secret, yet his empathy for people is also clear. His passion to use machines and rules to give people agency over their world was an important motive for founding Mallowfields. While he relishes the challenges of building digital machines, he values compassion over all else, no matter what a system is made of.


Architecture First

No actual solution starts with software. Recognizing and describing the systems and environments in which we live and work — and sometimes build digital machines — is more than requirements gathering, project management, or business analysis. Clear-eyed architecture, based on combined decades of success and failures, is the foundation of all our work, no matter how small the project.

Effective systems thinking starts with recognizing the limits of designed systems. We want to quote most of Systemantics by John Gall, the greatest (only?) satire in the field of systems theory. We will settle for just two more aphorisms, which offer a grounding perspective for us as even as we do the work that we love of designing and building human-digital systems:




But are you Agile?

We actually have our own manifesto, subject to change at any time:

  • Critical thinking over manifestos
  • Actual experience over certifications
  • Vegetables over meat, unless it's smoked or incorporates bacon
  • Pragmatism over computing religion
  • Technical depth over fad-chasing
  • Actual reality over compelling narratives
  • Thoughtful architecture over enthusiastic hacking
  • Obvious over clever
  • Utility over artistry
  • Humans over systems
  • Effective teams over "ninjas" and "rock stars"
  • No nonsense

Fine Print

No Nonsense

We don't hustle. We don't fake it till we make it. We are experienced and competent in our trades, and know both the depth of our skills and their limitations. We offer the skills and knowledge that we actually have, and that's enough.

We are comfortable saying "We don't know." We recognize that some problems can't be solved by us, and some problems can't be solved at all — at least not by software. We also know how to arrange and attack problems that we can solve, whether or not code is required.
