At TripFactory, I own architecture for the activities and car-rental platforms. I designed the activity booking engine and booking-management system, which scaled to 100K bookings per day, and built the activities platform end-to-end as it contributed to 25x business growth over three years.

I designed a supplier-integration framework handling 4M supplier API calls per day and integrated 11 suppliers across five regions. I also built an LLM content-creation pipeline that reduced catalog onboarding from months of operations work to hours.

Previously, at Mettl (a Mercer company), I built a reactive API gateway for a platform serving more than 1M concurrent test-takers and designed event-driven services. At Via.com, I built payment APIs and reconciliation services that cut the finance team's reconciliation effort by 80%.

I specialize in taking ownership of existing codebases: stabilizing them with resilience patterns and performance tuning, raising code quality, and continuing to ship new features. I’m open to long-term contract and freelance work, including backend ownership, maintenance retainers, feature development, third-party API integrations and system design reviews, and I’m comfortable working across European, Australian and US time zones.
