I am
Štefan Prokop
I help you design and create secure apps and Solana smart contracts or teach your developers to write secure code.
Security First Developer
About Me
I help startups, organizations, companies and entrepreneurs to design and develop their backends, APIs, chatbots and services / microservices.
I teach and train developers to write secure code and build secure applications.
I studied Software Engineering and Web Development on CTU (Czech Technical University) in Prague.
I create backends, APIs and software for almost 10 years, chatbots for 6 years and Solana for 2 years. I am focused on software security the whole career.
I worked for companies like Volkswagen, SKODA auto, Economia, Livesport, WITTE Automotive and several agencies.
I use Node.js, Rust, PHP, Google Cloud Platform, Firebase, AWS, (no)SQL databases, message queues ... I am comfortable with most of the backend technologies.
I like public speaking and writing. I am familiar with project management, leadership and human resources (onboarding, offboarding, recruiting and developer relations).
I am a freelancer (for more than 5 years) and digital nomad, currently I am working from Vienna (Austria).
I lead a healthy lifestyle - interested in biohacking. I would rather go for a walk than a beer.
I like jogging, going to the gym, meeting new people, reading, watching F1, and I am interested in personal growth.
