Senior🎓
Top SchoolJuan Romero is a senior software developer based in Calgary with over a decade of experience building browser-first web products, SDKs, and cross-platform reading experiences. He has led engineering teams and architecture at startups and scale-ups, shipping complex systems like a Kafka-powered eBook ingestion pipeline, an instant streaming EPUB reader with DRM, and a React/TypeScript storefront integrated with Stripe and Avalara. Equally comfortable in front-end and platform roles, he has driven TypeScript migrations, built internal SDKs that mirror React Native patterns, and maintained high-scale backends using Go, Kafka, and Postgres. An active open-source contributor, Juan refactored core components of the widely used Hypothesis web annotation client and has been a long-time maintainer and contributor to Readium’s EPUB rendering libraries. He pairs hands-on implementation with mentoring and process leadership, promoting DevOps, TDD, and API discoverability across teams. His work shows a consistent pattern: turning browser technologies into production-grade, multi-platform products that solve real publishing and content problems.
