Hello, I'm Ferdinand Ernst
DevOps Engineer | Fullstack Developer | DJ
See My WorkAbout Me
I am a passionate DevOps engineer with a strong background in Web3 technologies, cybersecurity, and cloud-native solutions. My work focuses on creating secure, scalable infrastructures and automating complex workflows. I have implemented IT awareness programs, training employees on phishing and data protection to foster a culture of cybersecurity awareness.
Adhering to clean code principles and Martin C. Robert's clean architecture, I ensure all solutions are maintainable, efficient, and robust. I mentor new employees, teaching them clean code standards and best practices. My technical expertise spans Kubernetes, CI/CD pipelines, Web3 integrations, and a variety of programming languages, including Go (my favorite), Java with Spring Boot, Angular, PHP with Symfony, and Bash.
Before embarking on my IT journey, I gained valuable experience in business and management. As a certified Wirtschaftsfachwirt and Betriebswirt (Business Specialist), I developed a strong foundation in business operations, financial management, and team leadership. This unique blend of skills allows me to approach IT challenges with a strategic mindset and a focus on delivering measurable business outcomes.
Outside of work, I have been DJing since 2015 and served as a board member of Zappeldrang, a DJ collective and registered association in Germany, from 2022 to 2024. I am also passionate about surfing, a hobby I picked up during a year in Lisbon. In 2024, I moved to Cádiz to hone my surfing skills further. Additionally, I love hosting events, having organized events of up to 2,000 people.
Another one of my hobbies is photography, with a special interest in street art and graffiti. You can explore some of my work on Instagram. Additionally, check out my DJ sets and mixes on SoundCloud.
I am also a huge race car fan and always happy to find the time to get on a track, enjoying the thrill and precision of motorsport.
