Engineers' Track Record
Our engineers have designed, implemented, and hardened systems at scale — before Kaarastu. Here's what that experience looks like.
Architecture Lead on every engagement
Our engineers have designed and operated transaction processing systems handling 100K+ transactions per day, maintained at 99.99% uptime. Failure tolerance by design, observability that surfaces issues before users notice, and deployment architecture that allows changes without downtime.
SaaS platforms serving 500K+ daily active users, with data residency requirements, real-time processing pipelines, and the reliability architecture that enterprise SaaS clients require.
Enterprise cloud migrations are architectural transformations. Our engineers have led migrations from monolithic on-premise systems to cloud-native microservice architectures, across 50+ service environments.
Real-time event processing at scale — on AWS and Azure — with the reliability and observability requirements that production event-driven systems demand.
Systems designed to operate across geographic regions, survive regional failures without user impact, and maintain data consistency across distributed deployments.
When we say 100+ years of combined engineering experience, we mean engineers who've held architecture leads, principal engineer, and senior engineering roles at companies operating serious production systems. Years spent making architecture decisions that other engineers built from, at companies where the consequences of a bad architecture decision were visible in production.
The team spans disciplines: platform architecture, reliability engineering, DevOps architecture, integration engineering, quality engineering, and operational systems. No engineer is a generalist who covers everything — each has a domain. When a reliability architecture question needs a reliability engineer, it gets one.
Every engagement is led by an architect from Discovery through Handoff. No sub-teams. No overhead layer.
Industries We Know
The engineers on a Kaarastu engagement have encountered the failure modes that theory doesn't predict. They've seen what happens when a circuit breaker wasn't in the right place. When an event-driven architecture had no dead-letter queue and lost data silently. When a cloud migration started before the service dependencies were mapped and stalled three months in.
That's not a pitch for experience points — it's a description of what you get when senior engineers review your architecture. The questions they ask come from having seen how similar decisions played out at scale. The risk register they produce reflects judgment developed over years of operating production systems, not a checklist derived from best-practices documentation.
Every engagement is led by a senior architect from Discovery through Handoff. No sub-teams. No overhead layer.
Architecture Lead on every engagement — not a project manager
Same team designs and builds — no handoff between strategy and execution
Fixed-phase model — defined deliverables, defined timelines, no scope creep
