About
Denis Frishchin
Netanya, Israel · working worldwide
Fourteen years spanning Tier III escalation, enterprise service management and hands-on platform engineering — on-prem Kubernetes clusters, AWS environments, CI/CD pipelines and the observability stack behind multiple R&D products. I build systems a single engineer can reason about at 3 a.m.
Today that discipline goes into client work as Frishchin Systems: apps, automations and AI integrations built like production systems.
How I work
Built to run, not to demo
Monitoring, backups and alerting ship by default. You hear about failures from the system, not from a customer.
Security by default
Hardened out of the box, not as an opt-in afterthought.
Minimal bloat
Every dependency is a liability. Ship the smallest thing that works.
Fix the system, not the symptom
Cut recurring incidents 16% by engineering out root causes instead of firefighting them.
