Fractional Payments & Platform Lead

A senior owner for the billing and platform roadmap — €8,000–15,000 a month, not by the hour

Sometimes you don't need more hands — you need someone who has seen the failure modes before. I've led teams through billing migrations where mistakes cost real revenue, modernized legacy platforms while they served customers, and advised founders from first commit through Series B. That judgment is available as a fractional payments and platform lead, €8,000–15,000 a month, for teams whose billing and platform have no owner. Not by the hour: hourly makes you ration the questions.

Architecture & audits

  • Payment system audits: where your billing leaks revenue and where it will break
  • System architecture review with scalability, security, and cost analysis
  • Technical due diligence for investments and acquisitions
  • Build-vs-buy and migration decisions argued with evidence, not preference

Leadership & process

  • Fractional CTO: roadmap, hiring, stack decisions, and vendor selection
  • Leading delivery teams — sprint planning, specs, code review standards
  • Engineering workflow and tooling decisions — including where automation belongs and where it doesn't
  • Mentoring engineers into senior ownership

Project rescue

  • Honest assessment of troubled projects — what's salvageable and what isn't
  • Technical debt triage with a sequenced, low-risk recovery plan
  • Stabilize, then improve: tests, monitoring, and deployment discipline first
  • Knowledge transfer so the rescue sticks after I leave

Stack & tools

  • Architecture
  • Payments
  • Marketplaces
  • Team Leadership
  • Process
