Technical insights from the engineering team at Kaev.
Application development for SaaS and AI tools
Architecture-first engineering for funded teams building SaaS platforms and AI products that need to launch cleanly and keep working at scale.
Why most startups over-engineer too early
Kubernetes at 50 users. Microservices with 2 engineers. The skill is knowing when not to scale.
How we built real-time threat detection in under 100ms
The engineering behind scanning every AI wallet transaction for prompt injection attacks without adding latency.
What a systems engineering agency actually does
Not a dev shop. Not a consultancy. A systems engineering agency builds the infrastructure that makes your business run itself.
Why your MVP architecture will cost you later
Move fast and break things works until things actually break. The decisions you skip now become the problems you pay for later.
The difference between automation and orchestration
Automation runs a task without humans. Orchestration coordinates dozens of automated tasks into a system. Most companies need both.
How event-driven architecture reduces system failures
When services talk directly to each other, one failure cascades everywhere. Events change that equation.
5 signs your backend needs re-architecting
Not every performance issue needs a rewrite. But some do. Here is how to tell the difference.
What self-healing infrastructure actually means
It is not a marketing term. It is a set of engineering patterns that let systems recover from failure without human intervention.
Why Rust over Node.js for production backend services
Node.js is fast to write. Rust is fast to run. Here is when the tradeoff matters and why we made the switch.
The real cost of building a system that breaks at scale
Your v1 worked at 100 users. At 10,000 it falls apart. Here is what actually goes wrong and what it costs to fix it.
