Freelance
fractional CTO
September 2023 - Today (2 years and 9 months)
As a highly hands-on Fractional CTO and parallel Tech Lead, I currently support several SMEs (10 – 100 employees) in modernising, securing and hardening their information systems. I balance strategic guidance with daily execution—code reviews, CI/CD optimisation, production supervision and vulnerability remediation.

Modernisation: legacy stacks replaced with hybrid or cloud environments defined via Infrastructure-as-Code, cutting major incidents by 4×.
Security: ISO 27001 baselines and tailored DORA/PCI-DSS road-maps implemented, slashing critical external-audit findings by 75 %.
Reliability: fully automated testing and deployments reduced release cycles from hours to < 20 min and achieved 99.99 % uptime.

January 2023 - September 2023 (8 months)
From 2019 to 2023 I held a hybrid position as VIP Service Delivery Manager and Head of Engineering. I led an in-house tech team (engineers + interns) and coordinated 40+ external contractors.
With 80 % of my time on project and people management, I set critical KPIs (uptime, MTTR, cost-per-transaction) and drove continuous-improvement programs.
The remaining 20 % hands-on work focused on modernizing client infrastructures through automation, stronger security and fewer critical incidents, blending strategic oversight with technical execution for high-stake accounts.

January 2017 - January 2019 (2 years)
As a fractional CTO for a SaaS start-up (< 100 employees), I engineered and launched the company’s entire technology stack—from on-premise servers to a fully automated CI/CD pipeline. Working hand-in-hand with the founder-CEO, I set the annual tech budget (~ €300 k CAPEX/OPEX), mapped the technology roadmap, and hired a cross-functional team of 11 (sysadmins, back-end and front-end engineers).

Through automation and agile delivery, production release time fell from 2 days to 15 minutes, while spinning up new development environments dropped from 3 days to 1 hour. The redundant architecture I designed delivered 99.9 % uptime.

Day-to-day, I steered IT governance, embedded a DevSecOps culture, and translated technical risks into business language for stakeholders, ensuring technology growth remained tightly aligned with strategic goals.
