Štefan in a few words

I am security first backend and blockchain developer. I provide services such as web or web3 app development, mobile (Android & iOS) development, backend and Solana blockchain development and I do security audits for backend and Solana apps. I work together with my colleagues but only I am responsible for our result.

My most provided services are development of serverless microservices (Google / Firebase Cloud Functions or AWS Lambda functions), connecting apps to third party services and webhooks implementations (Stripe, Jot Forms, Slack, Facebook API, etc.), creating REST APIs for web / mobile apps, development of MVPs and security code reviews / audits / implementations.

I have an experience with working for entrepreneurs, small and mid-sized companies, agencies but also organizations like Volkswagen or SKODA auto, and startups like WeShare.

My projects and references are available on my LinkedIn: linkedin.com/in/stefanprokopdev/

I follow the newest trends of development, visit conferences and trainings to improve my knowledge and skills. I love reading, biohacking - I have a healthy lifestyle, sports - jogging, swimming, watching Formula 1 and traveling. I am also interested in personal growth and finance / investing.

If you want, you can contact me here: linktr.ee/stefanprokopdev

I prefer remote work but sometimes I can work from your office, if you pay me the transport (flights / bus), accommodation and time on the way.
