Panos Kountanis is a seasoned software engineer with 14 years of experience building full-stack web apps, distributed backend services, native mobile and desktop apps, and low-level firmware. He has led major rewrites—most notably a PCI-DSS compliant payment service that retained backward compatibility—and driven performance improvements such as a 500% RPM/Server increase for Python/Twisted systems. Panos combines front-end finesse (reducing mobile payloads and overhauling autocomplete engines) with backend and API expertise, and has contributed to high-profile open-source WordPress projects like Jetpack and WP-Job-Manager. He also built an iOS theming, translation and localisation engine to streamline internationalisation, reflecting a practical focus on shipping user-facing features across platforms. Based in Greece, he pairs broad technical depth with hands-on delivery across the stack and occasional low-level hardware work that many full-stack engineers don’t touch.
