Lead Developer Vitec

Vitec GmbH • Vollzeit

Oct 2016 - Present • 9 yrs 7 mos

As Lead Developer at Vitec, I am responsible for turning business vision into scalable, production ready digital products. My role goes far beyond writing code. I define technical architecture, ensure implementation quality, and safeguard long term maintainability across mobile applications, web platforms, and SaaS solutions. If you are looking for task execution only, I am not the right fit. If you need a technical partner who takes ownership of scalability, system integrity, and sustainable product engineering, I am the right choice. Before development begins, I focus on clarity. Clear scope, defined priorities, realistic milestones, and technical feasibility reduce risk and protect investment. Many software projects fail due to poor structure at the beginning. My responsibility is to prevent that by designing clean, scalable architectures from day one. I lead cross functional teams and align engineers around structured technical standards. Clean code, documentation, and sustainable system design are non negotiable. I review architectural decisions, oversee backend integrations, and ensure performance, security, and scalability are built into the foundation. My expertise includes cross platform mobile development for iOS and Android using Flutter, SaaS platform architecture, backend system design, secure API integration, authentication systems, subscription and monetization logic, Firebase infrastructure, analytics integration, and structured release management for both Apple App Store and Google Play. In addition to new product builds, I conduct technical audits and modernization strategies for existing applications and SaaS platforms. When systems are poorly structured, I identify risks, define realistic improvement plans, and implement solutions that support long term growth and operational stability. I work best with founders, SMEs, and product owners who value clarity, accountability, and long term thinking.
