Avi K

I build AI automation systems end to end. Seven years on the customer operations side at Payoneer, Fiverr, Bancor, and stake.link gave me the lens I now build from: what real users actually need when they meet a system. Today I direct Claude Code and Codex as my primary development motion.

I ship agent stacks, RAG systems, knowledge layers, multi service orchestrators, and observability pipelines. I am comfortable in the seam between business problem and working software, and I treat that seam as the job.

AI Systems Builder at Ottomatt (2025-01 – Present)

Ottomatt (PoC stage), Israel. AI automation platform for Hebrew speaking SMBs

• Own the full stack as the primary builder: 15+ microservices, tenant isolated Postgres with forced row level security, Hebrew first WhatsApp surface, automated research pipelines, agent self improvement feedback.
• Shipped Noa, a humanized Hebrew agent with vertical specific prompt graphs (beauty salons, clinics, retail) and low confidence escalation paths to human operators.
• Wired Langfuse, OpenTelemetry, and Prometheus for per turn agent tracing. Every conversation observable, every decision auditable, every performance gap debuggable.
• Built an MCP server exposing Ottomatt tools to external Claude and Codex agents.

• Built the knowledge base content model and CSAT loops. Turned recurring support patterns into product requirements that shipped back into engineering.
