Developer focused on cloud + security

I build security labs and identity-first cloud solutions.

Strong networking foundation with a code-first path into security engineering. This site is where I publish labs, writeups, and demos across cloud and IAM.

About

I'm Billid Mohamed Jarquin Rizo. I focus on building and operating security in cloud environments, with a strong networking background and a clear developer track for automation and security tooling. I enjoy reproducible labs, clean documentation, and practical troubleshooting.

Reproducible labs with clear documentation and verification steps.
Security fundamentals: least privilege, logging, and change control.
Identity and integrations: SSO, MFA, provisioning, APIs and webhooks.

Labs and subdomains

A simple list of endpoints used for demos. Update these as you deploy services.

Name	Subdomain	Description	Status
Okta Admin	`okta.yourdomain.dev`	Tenant, OIDC and SAML apps, policies, users, groups	Planned
Auth Demo	`auth.yourdomain.dev`	OIDC flow, tokens, refresh, logout, session checks	Planned
API	`api.yourdomain.dev`	JWT validation + scopes based authorization demo	Planned
Status	`status.yourdomain.dev`	Health checks and basic observability	Planned

Tip: keep the portfolio on yourdomain.dev with Cloudflare Pages. Use Cloudflare Workers for APIs on api.yourdomain.dev.
