About Me

Engineering leader with a passion for distributed systems

I am a Staff+ Engineer & Architect with over 20 years of experience designing, building, and scaling mission-critical identity platforms, distributed services, and cloud-native ecosystems. My deep expertise spans Customer Identity & Access Management (CIAM), modern authentication/authorization protocols, and high-throughput architecture.

I have architected systems handling over 10 billion daily requests at major technology companies including eBay, PayPal, and General Motors. My experience spans the full spectrum — from designing fault-tolerant distributed systems and cloud-native architectures to integrating AI/ML capabilities and leading cross-functional engineering teams.

I thrive at the intersection of identity, security, and distributed systems, and I am passionate about building platforms that are not just functional but elegant, scalable, and resilient.

Identity & Security

CIAM, OAuth 2.0, OIDC, SAML, SCIM, MFA, Passkeys — architecting enterprise-grade auth.

Cloud-Native Architecture

AWS (Cognito, Lambda, DynamoDB), Azure (B2C, CosmosDB) — designing for scale.

Distributed Systems

High-traffic microservices, event-driven architecture, APIs handling 10B+ requests/day.

AI-Assisted Engineering

Driving adoption of agentic AI tools (Claude Code, Cline) to optimize velocity.
