Studio · Since 2015
Engineers first. Always.
An independent, founder-led practice. We take on a small number of engagements at a time and work with clients wherever they operate.
Where we workRemote-first, working with clients worldwide
How we operate
What working with us looks like.
The commitments behind every engagement, whatever the size.
- 01
Remote-first, worldwide
We work with clients across time zones. At kickoff we agree the hours we overlap and how quickly you hear back, and we keep to it.
- 02
Senior people on the work
The people who scope your project build it. You know their names before you sign, and they stay with it to the end.
- 03
A written plan before code
Every engagement starts with an audit and a written specification, so scope, cost and timeline are agreed before anything is built.
- 04
Something working every one to two weeks
You see a working build, not a status report, so you can change direction early, while it is still cheap to.
- 05
Security from day one
An ISO 27001 and SOC 2 certified practice. Access control, encryption, logging and testing are built in from the first sprint, not added at the end.
- 06
You own everything
Code, infrastructure, accounts and keys are in your name, with documentation and a proper handover. Support after launch is included.

Gideon Ondari, founder
A note from the founder
I trained as a civil and structural engineer before I wrote software for a living. On a building site nothing is decorative: every member carries a load, every joint is drawn, checked and signed off. I started Daf-Devs in 2015 to build software the same way.
That is why we start with an audit, draw the system before we build it, and decide up front which actions run on their own and which stay with a person. Security is not a feature we add. It is the foundation we build on.
When we finish, you own everything: the code, the infrastructure and the keys. We would rather earn the next project than lock you into this one.

Principles
How we work, in four lines.
- 01
Every action has an owner
Authority is set in configuration, agreed with you.
- 02
Every action is checked
The system confirms each action did what it should before the next one starts.
- 03
Everything is logged
Who or what acted, when, and on whose authority. Append-only.
- 04
You own all of it
At handover you hold every key. No lock-in, no licence on your own system.
Proof
Work you can open and inspect.
