Introduce yourselfFrequently asked questions
Straight answers about how we work with US, UK, EU, and multi-site teams.
We establish shared working hours, written decision logs, and demo cadences. Sofia’s EU time zone overlaps favorably with US East Coast and UK teams for real-time collaboration.
We right-size pods: tech lead, engineers, QA, DevOps as needed, plus design or data specialists. Recruiting engagements mirror the same seniority bar we use internally.
Absolutely. We routinely inherit brownfield systems, document as we go, and introduce improvements incrementally rather than risky big-bang rewrites—unless strategy calls for one.
We default to client-owned IP, signed NDAs, role-based access, and least-privilege environments. Enterprise paperwork (MSA/SOW, security questionnaires) is standard.
