👋 Hi, I’m Mary

I’m a full-stack software engineer interested in backend systems, developer tooling, authentication, observability, and practical product engineering.

I use this space to share side projects, experiments, notes, and open-source work around building reliable software.

• Backend systems and distributed application design
• Developer-friendly APIs and internal tooling
• Authentication, authorization, OIDC, and OAuth2
• Observability with logging, tracing, and metrics
• TypeScript, Node.js, Go, Python, Next.js, React, and cloud-native development
• AI-assisted development workflows
• Making debugging and operations less painful

🌱 I’m currently exploring

• Better patterns for event-driven systems
• OpenTelemetry for tracing and diagnostics
• Practical AI tooling for software teams
• Cleaner UI/UX patterns for developer-facing products
• Reliable infrastructure patterns for small teams
