What we hold ourselves to
The standards that make senior engineers safe to embed in your team and ready for enterprise due diligence.
Senior-only delivery
Every engineer is senior or medior. No juniors billed at senior rates, no offshore hand-offs.
Client-facing communication
Engineers who join your standups, write clearly, and can be trusted in front of your stakeholders.
Clear project ownership
A named point of contact who owns delivery, not a rotating pool of anonymous resources.
Transparent timelines
Honest estimates, visible progress, and early warning when something is at risk.
Structured QA
Testing built into the workflow, not bolted on at the end.
GitHub-based workflow
Pull requests, code reviews and documentation in your repositories and tooling.
Documentation & handover
We leave systems maintainable, documented and easy to hand back or extend.
GDPR-conscious EU delivery
EU-based teams, ready for due diligence and compliance review.
Proven through long-term partnerships
Long engagements with named clients, where the engineers stayed and kept owning the work.

Save the Children engineering case studyWhat our clients say
“The QuartzDevs team was able to implement a solution for our payment gateway issues and saved us tens of thousands of dollars in lost revenue, as well as time spent by our accounting, sales, and customer service teams to remedy these issues.”
Flo Stroe
Manager, Web Applications @ CALI Floors
“The QuartzDevs team of three engineers was proactive and assumed numerous responsibilities. Their lead was leading various aspects of the project's engineering work we were involved in. Despite the need to switch between his duties frequently, he maintained efficiency and the team has completed the tasks both cleanly and on schedule.”
Jamal Fares
UCAN Project Director @ Save the Children International
“The engineer from QuartzDevs was able to switch between complex projects quickly and smoothly. He also took the initiative when needed. Overall I was very satisfied with the quality of the work.”
