What I'm looking for

I'm looking to build secure backend systems and cloud platforms, solve complex fintech or SaaS problems, and keep improving engineering workflows while mentoring teammates.

I'm building secure .NET fintech platforms for an Australian consumer lending and credit-card business serving hundreds of thousands of active customers. I contribute across Mobile API, Application Journey API, and shared platform services.

I architected a new non-EML credit-card issuer integration, including domain modeling, idempotent webhook ingestion, card-state synchronization, and dispute-event routing. I also designed and own a centralized MFA/OTP service using .NET 8, Azure Service Bus, and Cosmos DB, maintaining sub-300 ms login latency under peak load.

Previously at MoneyMe through ZigZag Offshoring, I re-architected loan quotation and eligibility flows to improve quote-generation speed by about 30%. I introduced Redis caching, migrated secrets to Azure Key Vault, and built observability through Application Insights, KQL alerting, and distributed tracing.

I've also modernized warehouse and logistics systems with Blazor WebAssembly, built REST APIs and dispatch workflows for GoGoApp, and developed PHP web applications, WordPress plugins, and e-commerce sites. I enjoy Clean Architecture, cloud architecture, mentoring developers, and improving engineering workflows with Claude Code and MCP automation.
