Top SchoolJohn Voskuyl is a senior full-stack software engineer based in the San Francisco Bay Area who transitioned from seven years in structural engineering and project management to shipping web and mobile products since 2022. He combines strong product instincts—having joined early-stage teams and partnered with founders on UX and monetization—with hands-on expertise in TypeScript, React/React Native, Node.js, PostgreSQL, and cloud-native tooling. John has a track record of building reliable production systems: real-time fintech alerting and transaction workflows at Breakfin, modernization and zero-downtime SAML migrations at Precog, and observability and CI/CD improvements at Webscale. He favors pragmatic automation and testing (Playwright, Cypress, GitHub Actions) to reduce risk and speed releases, and has repeatedly improved operational efficiency through reusable APIs and event-driven architectures. Notably, his background in civil engineering informs a systems-oriented approach to design and process optimization, blending technical craft with strong cross-functional communication.
