Marian Hello is a founder and CTO with 12 years of software engineering experience, specializing in enterprise Java and modern JavaScript/Node.js stacks to deliver end-to-end logistics solutions. He founded Mapilary in 2013 and leads architecture, code reviews and product-technical translation for a suite of dispatcher, courier and consignee apps focused on last-mile delivery. Deep expertise in Java EE, webservices, XML/XSLT, and application integration is complemented by practical Android mobile work—contributions to popular background-geolocation projects demonstrate hands-on skills in location services, lifecycle handling and native Java refactoring. Comfortable across Linux/Windows administration, web servers (Apache/Nginx) and Java app servers, he blends systems-level ops knowledge with pattern-driven software design. Equally at home building backend APIs and improving mobile clients, he favors a unified JavaScript stack to streamline front- and back-end development.
