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.

Code Doctor - fix #techdebt broken Products

As an Innovator, I've identified critical challenges in the industry's entry, execution, and exit phases. Companies often struggle with hiring costs/delays, managing complex processes, and to achieve consistent production performance. 

This is evident in the industry average of successful projects and products being less than 30%, with over 90% of startups failing, and total technical debt ever growing to trillions of $.

To handle such challenges, I've introduced and successfully practiced an upstream innovation role: CodeDoctorship. This simple new role ensures that the hired team gets onboard rapidly and that team committed code meets the required cleancode standards without extra time. 

I have been implementing CodeDoctorship in more than 160+ instances of software firefighting, it has increased project success rates by over 70%. This approach handles code complexity and poor engineering practices, junior skill gaps without demotivating developers, as they view CodeDoctorship inputs as a WhiteBox QA team support provided by the system to improve code health for NFRs.

If this innovation resonates with your situation of fire and you're looking to detox and destress, feel free to reach out to me.
