Technology Executive, CTO & Hands-On Software Architect
I build digital products, AI-enabled platforms and engineering organisations that turn ambitious ideas into reliable, scalable technology.
I am a Berlin-based technology executive, software architect and entrepreneur with more than 25 years of experience across startups, scale-ups, enterprises and mission-driven organisations. My work spans technology strategy, product architecture, engineering leadership and hands-on software delivery, with a particular focus on AI-enabled and cloud-native platforms.
I am most effective where technology requires both direction and execution: creating a product and architecture from first principles, scaling an engineering organisation, modernising a complex platform, or helping teams deliver with greater speed, quality and confidence.

What I Bring
Technology Leadership
I define technology strategy, shape product and platform roadmaps, build effective engineering organisations and connect technical execution with business and mission outcomes.
Architecture & Engineering
I remain hands-on in architecture and software delivery, particularly across agentic systems, LLM applications, cloud-native SaaS platforms, APIs, distributed systems and DevSecOps.
Delivery & Transformation
I help teams move from complexity to measurable delivery through clearer ownership, pragmatic architecture, reliable engineering practices and shorter feedback loops.
Selected Outcomes
- Built an agentic DevOps platform from concept to customer-connected MVP: As technical lead for Major Tom, I architected and built core capabilities for a secure, multi-tenant SaaS platform connected to customer AWS environments, reaching an operational MVP within five months.
- Co-founded open-source AI infrastructure serving young people in Africa: As CTO of Tabiya, I led the development of AI-enabled and taxonomy-based labour-market tools. Tabiya’s inclusive skills taxonomy was deployed through SAYouth.mobi, a platform serving more than 3.8 million young people in South Africa.
- Turned around delivery for a mission-critical national digital platform: At Capgemini, I rebuilt the engineering capability for a complex public-sector programme, establishing a new cross-functional organisation and moving delivery from releases every two months to multiple integrations per day.
- Built and scaled a software venture through acquisition: I co-founded the venture behind the BONAPART process-management product line, led international product development and engineering, and supported its acquisition and integration into BTC AG.
- Delivered across complex and regulated domains: My work spans healthcare, manufacturing, energy markets, automotive, public-sector digital infrastructure and equitable labour-market access.
Who I Am Professionally
I have worked as a CTO, VP Engineering, technical architect, delivery architect, technology manager, product leader and hands-on developer. That breadth allows me to move comfortably between executive decisions, architectural detail, team development and the practical realities of shipping software into production.
My career has included founding ventures, advising early-stage companies, leading engineering in scale-up environments, delivering for major enterprises and building technology for social impact. Across these contexts, the common thread is a commitment to useful products, sound engineering and teams that can deliver sustainably.
I am drawn to work where technology matters: products that must become real quickly, platforms that need to scale safely, organisations that need stronger technical direction, and missions where software can create measurable economic or social value.
How I Work
I combine strategic thinking with direct involvement. I am comfortable defining technology vision, organisational design and platform strategy, while remaining close to implementation: shaping architecture, reviewing critical designs, building core capabilities, strengthening delivery pipelines and mentoring engineers.
My approach is informed by Agile, Lean and Software Craftsmanship principles: establish clarity, shorten feedback loops, make quality part of everyday delivery, keep architecture purposeful and create environments where capable people can perform at their best.
