🚀 I build enterprise SaaS platforms end to end: architecture, implementation and rollout. At E9 (Nov 2020 – Jul 2026) I grew from Software Developer to Senior Full-Stack Developer. My work covers enterprise authentication (Okta, SAML 2.0, role-based access control), workflow orchestration across multiple client environments, and real-time messaging on WebSockets with Redis and Google Pub/Sub.

• 🔐 Enterprise Authentication Platform: Okta single sign-on over SAML 2.0 with Passport.js and JWT, a route-to-permission RBAC model enforced by middleware, and a login audit trail.
• ⚙️ Workflow and Asset Automation: a repository-driven orchestration platform (Node.js, Vue.js, MySQL, GitLab and Jira APIs) with reusable automation modules, a visual workflow canvas, scheduled execution and webhook-based sync, plus Flexera One integrations that replaced manual audits.
• 📡 Real-Time Messaging Infrastructure: Socket.IO WebSockets with a JWT-authenticated handshake, per-tenant and per-user rooms, a Redis adapter and Google Pub/Sub sync, with Firebase Cloud Messaging push for offline clients.
• 🧩 Dynamic Form Builder: drag-and-drop form authoring in Vue.js with Jira REST API ticket creation and configurable per-client branding.
• 🛠️ Background Jobs: BullMQ and Redis queues with retries, exponential backoff and scheduled jobs for a multi-tenant transportation SaaS platform on Node.js and SQL Server (Prisma).
• 🧪 Quality Engineering: a Cypress end-to-end framework with custom commands, stable data-testid selectors, network interception and fixtures across login, roles, vault access and the form builder.

• 💬 Ask me about: Node.js, event-driven architecture, WebSockets, MongoDB, auth and SSO, Vue.js
• 🌱 Currently going deeper on: React, TypeScript, PostgreSQL, system design at scale
• ⚡ Fun fact: 🎢 I once debugged an issue while on a roller coaster!

• Podiom #347 — table-driven tests for the adapter router, pinning guard order and error-wrapping behavior (Go)
• career-ops #4615 — web runs dated artifacts in UTC, not the user's local day; fixed and guarded with a regression test (v1.35.0)
• warp #344 — accessible name for the NAT/STUN diagram, so screen readers describe what it shows
