What I'm looking for

I'm looking to build secure, scalable cloud-native backend platforms, solve complex identity and wallet challenges, and collaborate with product, security, and engineering teams on reliable customer-focused solutions.

At HID Global, I build backend platforms for digital credentials, mobile wallets, and secure identity experiences. My work supports credential provisioning, authentication workflows, and integrations across Apple Wallet, Google Wallet, Samsung Wallet, wearables, smart cards, and security tokens.

I've engineered high-availability services managing 10M+ mobile wallet credentials annually at 99.9% uptime. I improved transaction efficiency by 25% through Smart Tap NFC implementation, reduced credential provisioning time by 30% for 10,000+ daily active users, and improved device authentication accuracy by 20% with a Device Eligibility API.

I work across Java, Spring Boot, AWS, microservices, serverless workflows, and event-driven systems. I've also built real-time pipelines processing 100,000+ daily records, improved search performance with OpenSearch, and delivered Grafana dashboards that make platform operations easier to understand and act on.
