What I'm looking for

I’m looking for a team where I can build secure, AI-enabled microservices and high-throughput data pipelines—then mentor others while driving reliability, clean architecture, and safe AI/ML integration in production.

I’m a Senior Software Engineer with 10 years of experience delivering AI-driven, cloud-native solutions across healthcare, banking, and industrial IoT. I specialize in designing secure, scalable microservices and high-throughput data platforms that stay reliable under real-world load.

At Bendigo and Adelaide Bank, I migrated monolithic APIs into event-driven microservices using asynchronous messaging (Kafka/RabbitMQ) and optimized backend performance for mission-critical systems. I built ingestion pipelines from hospital systems, devices, and third-party feeds using Python, FastAPI, and an AI orchestration layer, ensuring HIPAA-aligned handling of sensitive data and HL7/FHIR-based integrations with EHR systems.

I’m also a hands-on engineering leader who sets coding standards, reviews architecture, and mentors engineers while improving distributed systems, Azure, and safe AI/ML integration. I’ve built LLM-powered clinical assistants with Azure OpenAI, designed gRPC/GraphQL/REST interface contracts, and achieved 99.99% availability through production-grade reliability practices.
