What I help with

Platform modernisation & migration

Consolidating sprawling service estates into maintainable architectures — phased, reversible, and shipping the whole way. Reverse-engineered maps, delivery sequencing, change-data-capture cutovers.

Backend architecture & APIs

System design for high-traffic platforms: event-driven and domain-driven services, API-gateway strategy, payments and financial systems, idempotency and reconciliation.

Reliability & cost

Distributed-system reliability, observability and trace correlation, load testing, and infrastructure cost reduction — cutting rented complexity without a big-bang rewrite.

About

14 years shipping backends teams rely on.

Currently leading the consolidation of a 60+ service legacy platform at Carro / Kaidee into a modular architecture — a designed ~$204K annual GCP saving and a custom CDN/WAF replacing Akamai. Before that: Australian fintech consulting (escrow payments), and Wave Money, Myanmar's largest mobile financial services platform.
