Hyan Kelwin is a pragmatic Full Stack Software Engineer with 9 years of experience building high-impact web and mobile products across retail and employability platforms.

Hyan combines hands-on implementation (from mobile apps and monitoring to internal backoffice systems) with strong engineering craftsmanship, including test-driven delivery and design system contributions. He also drives team health through documentation, onboarding and process rituals, and has experience leading integrations, automation bots and technical hiring. Based in São Paulo, he pairs a taste for practical product impact with a curious drive for solving the “unbreakable” problems that others avoid.
