I’ve worked with many engineers over the past ten years, and Markus is a beast. He’s self-directed, thoughtful, and fast. He has excellent written and verbal communication skills and is candid and direct when his opinion is asked. I reached out to him for some unorthodox app development based on his GitHub profile and what I feared would take weeks and thousands of dollars was complete in days and far beyond my expectations. My only hesitation in writing this review for him is that I want all his time for myself and have no doubt that he will be in high demand, given his skill set and personal qualities. Grab this guy quickly because he’s about to be in limited supply.

Markus came to the Ferdi repo, and started reporting bugs, and some fixes. Within a short period of time (if I remember, it was literally 3-4 weeks), he had a good grasp of the complex, legacy app - and was suggesting discussions, raising PRs, commenting on bugs reported by others, etc. - all the responsibilities that a maintainer on any OSS project does. His genuine passion to fix bugs, suggest and implement enhancements (be they small or big) - is astounding to me. Over the past few months, he has been a bedrock and a great co-collaborator on this journey, and I have high hopes for the future of Ferdi with him being so active!
Vijay Aravamudhan, Maintainer of Ferdi
Markus consistently exceeds on everything he delivers, and is always thinking ahead, anticipating and mitigating any and all problems that might arise. On top of being highly competent, self-directed, and ready to tackle and embrace new solutions, Markus is also a fantastic communicator. He meets every deadline while still retaining the grace and patience to thoughtfully explain and optimize every step along the way, and his leadership skills are invaluable to our team.
Isaac Bock, Full-Stack Developer of PayMail
On every project I worked on together with Markus, he was an essential part of the team. With his high demand for software quality and a smooth development workflow, he has always contributed significantly to the success of the projects. He is constantly learning and using the latest technologies and is very good at passing on these learnings to the team. He always keeps the bigger picture in mind and his calm but direct manner is conducive to strengthening the team spirit and creating a good working atmosphere.
Matthias Eigner, Founder of CodeCove
Markus is a very reliable and attentive developer who plays an important role in creating our frontend MVP for injury.com. He is in charge of pull request reviews, modernizing the codebase, and keeps dependencies up to date. Additionally, he is responsible for implementing and pushing forward e2e and unit tests to provide test coverage for the entire project. We value his excellent work and he is a great addition to the team!
Noah Blumenthal, Founder of Injury.com
I am glad that twice I had a chance to work with Markus in one team! I can highlight his aspiration of clean code, maintainability, and automation. Markus is very open to new technologies and tries to understand how things are working in-depth rather than just cover basics. Aside from his impressive tech skills, he is also a nice person to chatting with, and he can always recommend a great craft beer!
Dmytro Mezhenskyi, Author of Decoded Frontend
I highly recommend Markus as an exceptional developer — who is dedicated to producing quality code. He completes his tasks beyond expectations, adds thoughtful discussions to the greater picture of a project, and cares about the projects he works for. It would be a pleasure to work with him again in the future.
Robin Wieruch, Founder of Robin Wieruch
I had the pleasure of working with Markus on a large e-commerce project. He has very strong technical background knowledge, with which he has significantly improved the development experience for a team of over a hundred developers. I will be very happy to work with him again at the next opportunity and can recommend him unreservedly.
Jonathan Häberle, Founder of Alm Engineering GmbH
Markus Hatvan is a great front-end Svelte developer. He did an excellent job for our company, and he was also a valuable team member. He communicated well, was reliable, and could be counted on to be available when needed. I would recommend him to anyone in need of a front-end developer!
Francois Lamotte, Founder of Pageverify
Markus is an excellent developer and certainly produced great work for us. He’s also a great team player: reliable, communicating well, and proposing solutions. As project complexity increases, this second part can be a real lifesaver.
