Oshri Cohen

Hey, I’m Oshri Cohen — Fractional CTO turned full-time tech whisperer.

I’ve spent the last 25 years immersed in engineering, and the last 15 leading brilliant (and sometimes delightfully chaotic) teams as a technical executive. From scrappy startups in healthtech and martech to 350-person research firms and Series C rocket ships, I’ve done it all: scaled orgs, refactored disasters, rescued investor confidence, and shipped things that didn’t catch fire on launch day. Wins all around.

30 companies in 4 years as a Fractional CTO? Yep. That’s not a typo. I embedded myself in each like a method actor in a startup biopic, just without the Oscar, though I’ve definitely made acceptance speeches to my dog. I solved mission-critical problems, rearchitected platforms, hired and levelled up teams, and created product strategies that actually made sense. And money.

At my core, I’m a systems thinker. Whether I’m rebuilding a microservices architecture, designing OKR cascades across dev teams, or explaining to a founder why their dev team is two PRs away from mutiny, I bring clarity, structure, and technical depth without the buzzword bingo.

Tech Stack? I could rattle off a list as long as your LinkedIn scroll: Python, Golang, React, gRPC, Kubernetes, Postgres, DDD, CQRS, EKS, Redis, you name it. But the truth is, I treat tech like tools, not religion. What matters more is why we’re building something and who we’re building it for. And how fast can we deploy without breaking production? (Or spirits.)

I help engineering orgs reach Elite DORA status in months, not years. Devs love working with me because I obsess over DX: If you can’t boot the stack with one command in under five minutes, we fix that. I also enforce quality through intelligent code review delegation and AI-assisted tooling. Let’s just say, if your platform smells like legacy spaghetti, I’ll turn it into clean lasagna.

If you’re building something great or something messy but full of potential, and you want a tech leader who can code, coach, scale, and simplify, let’s talk.
