Senior🎓
Top SchoolDenzel Giraldo is a founder and full-stack software engineer with nine years of experience building web and mobile products that streamline operations for small businesses, especially barbershops and salons. Based in New York, he founded Perceny to eliminate paper workflows and automate commissions, payments, and financial tracking for shop owners and stylists, drawing on prior hands-on projects that delivered real-time earnings dashboards. He also cofounded ImWhile to accelerate hiring and MVP delivery for startups, demonstrating a blend of product-first entrepreneurship and engineering execution. His technical background spans TypeScript, Node.js, React/Angular, PHP, and real-time systems, with a history of improving security, performance, and developer productivity across teams. Notably, he built early salon management platforms that replaced manual ticket counting with instant financial insights—a practical detail that foreshadows Perceny’s mission. Denzel combines startup grit with enterprise experience from roles at Wärtsilä and Axle Informatics, making him comfortable scaling both prototype features and production-grade systems.
