At Flatiron Software, I own the UI for a remote team serving a Florida media group. I migrated a legacy Vue app to React and TanStack, and connect it to backend endpoints as they ship.

At Novva Solutions, I build B2B SaaS MVPs end to end with Node.js, TypeScript, React, Next.js, and PostgreSQL. I’ve automated workflows and implemented billing with Stripe and Asaas.

On Articles.ai, I built and operated a content generation and publishing pipeline that produced 7.5K+ SEO articles and 22K+ images, reaching 100K+ views and 100+ paying customers. I maintained 99%+ uptime with retries, idempotent workflows, and structured logging and monitoring.
