Summary
👤
Senior🎓
Top SchoolRick Foxcroft is a Senior Software Engineer based in Perth with a decade of experience building high-performance backends for AI products, most recently in regulated medical imaging. He specializes in memory, latency, throughput and distributed-state problems, having cut peak memory 7x and average memory 13x on a core radiology inference service and designed Rust microservices to stream gigabyte-scale slide images reliably. Comfortable owning systems end-to-end, Rick has led observability overhauls (migrating from Jaeger to OpenObserve), driven trunk-based development and TDD at scale, and embedded ML inference into production in serverless and Kubernetes environments. He repeatedly serves as the technical escalation point for performance and distributed-state incidents, runs architecture reviews, and hires senior engineers without lowering the bar. Notably, he pairs low-level profiling and Rust’s concurrency model with pragmatic developer experience improvements—like cloud-backed remote dev environments—to shorten inner loops and keep teams productive.
