Senior engineers only
No juniors on production code. Minimum 8 years average experience on every team. You talk directly to the engineers building your product.
About our team
Architecture before code
Every engagement begins with a written technical specification. No code is written until the architecture is agreed. Your estimates are accurate.
Our approach
No surprise invoices — ever
Fixed-price projects run to scope. If we mis-estimate, we absorb the overrun. We have never passed an estimation error cost to a client.

RealEstate · KBT · 2026

EdTech

An LMS platform serving 200+ institutions required a zero-downtime migration to a modern cloud infrastructure. Key Brains architected and executed a phased migration plan, moving the entire platform to a containerised, auto-scaling stack without disrupting a single class or learner session across the network.
