Oscar Romero
@oscarromero1
Full Stack Software Engineer at Teachable who shipped self-service enterprise tiers and lifted AI course-outline generator conversion by ~5%.
What I'm looking for
At Teachable, I rebuilt the billing page into a usage-based monetization surface for 24K+ paid schools, enabling automated overage invoicing and targeted upgrade prompts. I also shipped self-service enterprise tiers for high-ARPU creators.
I supported the Chargebee-to-Stripe creator-checkout migration by building webhook processing and subscription-lifecycle management in a Go/Gin entitlement service. I also led development of a centralized design system adopted by five customer-facing production systems, cutting branding-related support tickets by about 50%.
At Teachable, I piloted AI tooling for the engineering organization, including a custom agent orchestrator and reusable agent skills. I also built an AI course-outline generator that preserved pre-signup work through account creation and lifted funnel conversion by about 5%.
At Speakflow, I migrated JavaScript bundling to Vite Ruby, improving build times by 40%, and engineered an async PostHog analytics pipeline that increased user retention by 10%. Across my other software engineering work, I’ve improved conversion, performance, and developer workflows, and I do my best work on communication-first teams that value continual learning.
