Software Engineer

I'm Exiequielle John Frias, a frontend-leaning full-stack engineer with 8+ years of shipping production web apps. Most people just call me XC.

At BillEase, a Philippine fintech, I build customer-facing flows with Vue, Nuxt, TypeScript, and Tailwind — KYC onboarding, ID and liveness verification, account recovery, payments, and a new credit line product — and maintain production Python APIs.

I build with AI agents by default — Claude Code and Cursor, with MCP integrations for Figma and ClickUp. AI handles the repetitive parts so I ship faster; architecture, UX decisions, and code review stay in my hands.
