How I can help

01

Fractional Head of Engineering

Interim or part-time engineering leadership for marketplace teams that need direction now.

  • Org design and team scaling
  • Coaching engineering managers
  • Feedback, ownership and delivery practices

Done before: Head of Engineering for SMG Real Estate B2B; grew Homegate's team from 2 to 6.

02

Marketplace mergers and integration

Bringing two platforms, and the teams behind them, together without losing momentum.

  • Platform and codebase integration plans
  • Aligning orgs, processes and ownership
  • Retiring duplicate legacy systems

Done before: Part of the homegate.ch and immoscout24.ch merger at SMG, and the acquisitions of flatfox and immoverkauf24.ch.

03

B2B monetisation and product

Engineering that grows revenue from the professional side of a marketplace.

  • Product ladders and packaging
  • Third-party services and partners
  • Billing and transaction systems

Done before: Led engineering for a B2B line worth around 40% of SMG revenue.

04

Build and modernise platforms

Hands-on architecture and delivery when the platform itself is the bottleneck.

  • Identity and authentication
  • Centralising customer data
  • Data aggregation and AI extraction on AWS

Done before: Built Homegate's AWS Cognito auth; built and run JobCrawls end to end.
