About

A full-stack engineer who ships

I'm a full-stack developer who's equally at home building a customer-facing interface and rewriting the backend logic a business actually runs on. Since 2022 I've shipped production UI, customized live ERP systems, and designed a feature-flag workflow that cut release time by 60% — across banking, healthcare, and energy-sector environments where getting it right matters.

  • Designed a feature-flag release workflow that cut time-to-ship by 60% and eliminated recurring QA bottlenecks.
  • Customize a live ERP system's HR, CRM, and admin logic in Python/Frappe — business-critical work most frontend-first developers never touch.
  • Ship production software end-to-end: React.js/Next.js interfaces, Node.js/Express APIs, and the MongoDB/MariaDB data layers underneath.

Skills

Tools I reach for

Comfortable owning a feature from interface to database — four frontend frameworks, two backend runtimes, and the practices that keep production systems from falling over.
