Freelancer profile translated to English.
Back to original languageAbout Axel
I support founders and early-stage teams as a Fractional CTO / CTO sparring partner to make the right tech, product, and AI decisions without immediately hiring a full-time CTO.
My role: challenge a roadmap, frame an MVP, clarify an architecture, evaluate service providers, prepare for tech hiring, identify product/tech risks, and avoid costly early choices.
I have a hybrid profile of founding engineer, VP Engineering, and data/platform engineer: applied AI, cloud architecture, data platforms, B2B products, growing teams, and startup environments.
I work primarily remotely, with extensive experience in distributed and near full-remote teams. Possible formats: sparring sessions, tech/AI audits, monthly advisory, or light fractional CTO support.
No fixed-price development: only senior consulting, framing, arbitration, and operational support.
