Horațiu Udrea

Hello there! I'm an **Android Technical Lead** with **9+ years** of experience in the programming industry and massive expertise in **Kotlin Multiplatform**. I'm really passionate about **creating, using and combining synergetic tools** - that's how I ended up being immersed in the Kotlin ecosystem. There's something that just clicks for me when things combine perfectly. I've worked in a multitude of projects and environments as a freelancer, and in all of them my role was to solve the most complicated issues regarding architecture, compile-time safety, code design, guidelines and performance. I'm in close contact with the Kotlin community - helping fellow developers with a diverse set of issues that they have. This also helps me get a better grasp on different parts of the ecosystem. If you could use the help of a programming wizard, let's chat and see if we're a fit!

I enjoy helping people understand how to solve problems and learn, and I have been tutoring for a while, but I have a limited number of students and would like to increase my workload. I would like to assist more students in becoming proficient in programming.

Benjamin Kappel

I'm a NET Core developer to the bones. My co-workers always describe me as a having integrity, reliable person and I am able to create a trustful environment where candid feedback can flow freely. I took the biggest step from the last job, where I was hired to review and audit the code and the technical solution of the product under development. My contribution to this project was pushing the product from an intentional state into something that created pleasure and happiness for nearly every stakeholder. In addition, In my free time, I'm engaged in an open-source community. My contribution ranges from explaining, PR reviews, fixing bugs, and creating new features with the result of creating one of the most loved solutions in that space (or niche).
