What I'm looking for

I'm looking for mission-critical security architecture work where I can build resilient IAM, Zero Trust, federation, and high-availability platforms while collaborating across vendors and distributed teams.

I've spent over 17 years architecting, scaling, and protecting mission-critical identity and access management infrastructure for large-scale eGovernment ecosystems serving millions of citizens.

I design federated identity platforms using OAuth 2.0, OpenID Connect, SAML 2.0 SSO, RBAC/ABAC policies, privileged access controls, token governance, and reverse proxy integrations. My work centralizes authentication policies and supports secure access to critical digital government applications.

I've tuned relational databases and enterprise LDAP directories, including multi-master replication, custom schemas, bufferpools, memory agents, and log allocation, sustaining 99.99%+ operational stability through major traffic spikes.

I also lead L2/L3 incident escalation, zero-downtime production maintenance, Linux high-availability operations, load balancing, security hardening, and AI-assisted debugging through Python, Bash, LLM workflows, and modern DevOps practices.
