Fullstack Developer
Bynet Communications
An AWS Lambda pipeline ingesting global device metadata across network boundaries into Kafka: four topics, one of them millions of messages a day, managed with Terraform.
A disaster recovery system with consensus logic written from scratch: every standard failover tool wants three nodes, I had two. Dual-layer failure detection, automatic promotion, self-healing in production.

About
Three years writing production code. Now taking that same standard to freelance work.
I like the problems where the obvious tool doesn't fit, like the failover system that wanted three nodes when I only had two. On client work that shows up as sites that load fast, read clearly and don't need me to keep them alive. Hebrew or English, local or remote.
