Alan Hadyk

Hi! My name is Alan. I’m a Software Engineer with over 15 years of hands-on experience building real products. I’ve worked on SaaS platforms and built dashboards used by over 22,000 brands. I turned many designs into successful e-commerce sites, bringing in 2M+ PLN in revenue. I’m currently building a local-first mobile app in React Native, with real-time collaboration. I’m comfortable working remotely with teams across the world. I care about clean, maintainable code and building things that users love. Wanna talk? Contact me at alan.hadyk@gmail.com.
