How I can help

Outside of my day-to-day at Revenue Monster, I take on a limited number of projects and advisory engagements — mostly around building systems, mobile apps, migrating legacy platforms, and helping businesses figure out their tech decisions.

What's on offer

Where I can be useful

01

Systems & Infrastructure

Backend systems, APIs, and cloud infrastructure built to hold up under real traffic.

  • Architecture and infrastructure design, from scratch or on top of what you already have
  • Kubernetes, cloud cost management, observability, and security hardening
  • Payment and fintech systems specifically — I've built these under regulatory scrutiny
02

Mobile Applications

iOS and Android apps, backed by the infrastructure to actually support them.

  • React Native apps from prototype to production release
  • Native integrations — payments, KYC, device features
  • Built with the same backend and security standards as the rest of the system
03

Legacy System Migration

Moving old, brittle systems onto modern infrastructure without breaking what already works.

  • Migration planning with a real rollback strategy, not just a cutover date
  • Incremental migration where a big-bang rewrite is too risky
  • Done alongside the team that has to live with the result
04

Technology Advisory

Help figuring out what to build, what to buy, and what to leave alone.

  • Technical due diligence and architecture review
  • Advisory for founders and business leaders navigating tech decisions without a technical co-founder
  • IT policy, compliance readiness (PCI DSS, e-money), and vendor evaluation
