Umut Benzer
I help companies scale their products, infrastructure and engineering teams.
I built parts of Auth0: Organizations, RBAC, Self-Service Enterprise Configuration. 8 years inside, 15+ in software. Now independent.
Problems I solve
If one of these is on your plate, let's talk.
You're setting up Auth0 from scratch
Greenfield Auth0 implementation, and you want to do it right the first time. Tenant architecture and scaling decisions made now save you a rewrite later.
Your Auth0 tenant grew organically
Years of Actions, Rules, and ad-hoc config. You're not sure what's safe to change, what's a footgun, or what's silently introducing risk.
B2B SaaS: Organizations or separate tenants?
Multi-tenant identity is the architectural decision that's most expensive to undo. I led the Auth0 team that built Organizations. I can help you pick the right model.
A migration to Auth0 is stalled
You're moving from a homegrown system or another provider. I co-pilot the work. I know the Auth0 side cold and your team brings the source-side context.
You need senior judgment, not a full-time hire
Architecture decisions, technical strategy, and hard calls on direction. Embedded part-time, with depth from running systems at real scale.
Your senior hiring bar is drifting
You're growing the engineering team and the interviews aren't producing the right signal. I help design hiring loops, write rubrics, and run technical screens.
Two ways I work
Specialist for identity work. Generalist for the engineering org around it.
Specialist
Auth0 & Identity
Deep-dive Auth0 work: implementation, audit, migration to Auth0, multi-tenant architecture. I built parts of this product. I know its sharp edges.
- Greenfield Auth0 setup and tenant architecture
- Production-readiness audits on existing tenants
- Multi-tenant / B2B identity architecture
- Migration to Auth0 from other providers
Generalist
Fractional engineering Leader
Senior engineering judgment without the senior engineering headcount. Architectural calls, hiring decisions, the moments you need a sounding board. 15+ years of building and leading teams, I bring all of it.
- Fractional CTO / Staff Engineer (2–3 days/week)
- Architecture review and technical strategy
- Hiring loops, rubrics, and technical screening
- Mentoring senior engineers toward Staff-level
What former colleagues say
Recommendations from peers, leads, and PMs at Auth0.
Umut is one of the best engineers I've ever had the pleasure of working with. Intelligent, thoughtful, and genuinely delightful to collaborate with.
Carlos Mostek
Product Architect · Auth0 by Okta
A great and thorough Staff Software Engineer and a kind Tech Lead. As amazing at solving problems as he is at mentoring people.
Riccardo Cocetta
VP of Engineering · Auth0
A rare ability to break down complex technical challenges into clear, digestible explanations. Whether speaking with engineers, product, or stakeholders, he ensures everyone feels informed and confident in the direction forward.
Sheena Allan
B2B SaaS Product Manager · Auth0
We had a particularly rocky project to launch, and Umut brought clarity and led decisions throughout. I'd recommend working with him in challenging or complex environments, where he brings clarity and enhances ways of working.
