At Everlabs, I owned billing and payments for Loyaltie, a SaaS subscription marketplace, and built its payment flows across a Rails API and Next.js frontend. I designed subscription and billing flows and built Stripe and PayPal webhook processing with idempotent handlers.
I also built a queryable store for provider events, reducing discrepancy investigations from hours to about ten minutes. I contributed to Loyaltie's AI-driven onboarding and natural-language search, and have worked on Rails APIs, integrations, and query optimization at ErgoServ, Upwork, and PixelGrow.
