About the Principal
Vangelis
CTO & Founding engineer at Doctoranytime
Engineering background with deep involvement in product strategy and growth execution. I've led teams through the scaling challenges—delivery velocity, reliability, platform evolution, and cross-functional alignment.
Hands-on when needed, strategic when it matters. I can advise at the exec level and still go deep with engineers on architecture or code. Strong bias for pragmatic solutions, measurable outcomes, and shipping.
“Operator, not slideware.”
Recent work
Examples of the problems we help teams solve.

Critical appointment booking system was unreliable under peak load. Missed bookings, frustrated users, lost revenue.
Outcomes
- 99.9% booking reliability (up from 94%)

Release Risk Reduction
Releases were risky and unpredictable. Team avoided shipping on Fridays. Rollbacks were common.
Outcomes
- Release confidence increased—team ships any day
- Rollbacks reduced by 80%
Growth-Stage Startup
Product & Engineering Alignment

Outcomes
- Roadmap stability improved significantly
- Team velocity increased after initial dip
E-Commerce Platform

Common questions
Answers to things people usually want to know.
You work directly with senior operators who've built and scaled engineering teams. No junior consultants, no handoffs, no decks that sit in a drawer. We focus on outcomes you can measure.
It depends on the challenge. Sprint diagnoses take 1-2 weeks. Project work runs 4-12 weeks. Advisory retainers are ongoing monthly. We'll figure out the right fit in our first conversation.
We can review code, pair with engineers, and dive deep when needed. But our focus is on leverage—the decisions, systems, and processes that multiply what your team can do.
We augment, not replace. We work with your CTO, VPE, or engineering managers to solve specific problems. The goal is to build capability that stays after we're gone.
We've worked across healthcare, fintech, B2B SaaS, and marketplaces. The patterns of scaling engineering teams translate well across domains.
