Hello, my name is Jonas Pietzsch (my previous surname was Verhoelen). I am passionate about solving problems related to business, software and people. The search for the right approach to solving problems puzzles me on a technological, human and organizational level. On the path of eternal learning I prefer to work in communicative and open-minded teams. Agile and maker mindset over meetings, flat hierarchies over leading positions and ivory towers - this is where I feel safe and productive.
Speaking about tech
I’m often working somewhere in the JavaScript universe using things like Node.js and TypeScript. In the beginning of my career I started in the Java ecosystem. What stayed is my preference for a good mix of object-oriented and functional programming and a desire for Clean Code. Since I strongly believe in T-shaped people and cross-functional teams I feel home in digital product development taking care of everything involved. Frontend, backend, infrastructure and all other aspects. Since 2020 I’m especially excited about Serverless, event-driven architectures in public clouds like AWS. Every now and then I contribute to open-source software on Github or publish tiny tools myself.
IT Security
I’ve been interested in information security since I caught the first keylogger from an ICQ contact when I was young. Not much has changed since then. IT systems still have lots of tricky vulnerabilities that developers have to take care of. Especially when software tends to be developed more and more faster nowadays. That’s why I attach great importance to teach awarenes about IT security, consolidating the basics and taking appropriate countermeasures against cyber security threats. Ethical hacking, penetration testing and CTF (Capture the Flag) help me to understand acute threats and motivations of hackers and to take countermeasures in application development.
Blockchain and crypto currency everywhere
Topics around blockchain, distributed ledger technology and Bitcoin have fascinated me since early 2016. Even though these topics got more and more notorious since then, I still find it important to reason about its original core aspects: decentralisation, privacy, equality and transparency in society and IT. I do not consider myself an enthusiast or evangelist but my journey through this realm coined me.
Hobbies
I spend a lot of my time with guitars, heavy metal music and road cycling. Besides that I love spending time with my wife, dog, family and friends. I developed an interest for the challenging topic of climate protection which I see as todays biggest threat to mankind. That’s why I started becoming more environmentally friendly myself and using this knowledge also in the industry.
