Engineer and founder
I'm Zak Kann. I founded Content Raptor, a B2B AI SaaS, in 2023 and built it solo: the AWS architecture, the LLM pipelines, the product, the customer onboarding. It reached 300+ paying customers and ingested 3M+ Google Search Console rows a day. For three years I was the only engineer and the only person on call.
Alongside it I've consulted through Zak Kann, LLC since 2020, mostly AWS architecture and automation builds. I've shipped 110+ automations across marketing, operations, and customer success. The most recent was an AI-powered partner-payout system for an early-stage startup; it saves them roughly 20 hours a month and took about a month to deliver.
This year I've been publishing the infrastructure patterns from that work as open source. The pieces so far: a FinOps engine that reads an AWS bill and flags dollar-quantified savings, with a public MCP server, and a multi-model LLM router. There's also a retrieval service with a measured eval harness. All of it is at github.com/zkann.
Before that
A PhD in computational chemistry, senior data scientist roles building production ML pipelines, and a turn as co-founder and CTO of a pre-seed startup, where I led four contract engineers to a paid beta. The thread through all of it is measurement systems and the infrastructure underneath them.
What I do now
- AI automation for businesses that don't have an engineering team.
- Fixed-price AWS cost audits, with a published sample report.
- Architecture work like the Content Raptor backend.
