About Me

Frontend, Javascript & APIs are my cup of tea

I'm freelance Javascript & Frontend Developer

For my clients I'm creating nice looking applications using several UI libraries, which are together with modern Javascript giving the users a smooth feeling using the website.
User's impression is the key point of websites I'm creating.

I'm able to deliver a whole application with complex business logic created from top to bottom or participate as a team member on the frontend part.

What I Do



I have most experience with Vue on frontend. I have built several projects for my clients as well as my private projects on this framework. It was my first choice for a long time.



I like the idea of one programming language for both, the FE and BE. It is a good choice for building lightweight but scalable APIs. My choice No 1 for backend recently.



Although I'm still using Vue more, Svelte is the future. It is boilerplate-free js framework compiled to a native javascript which gives the code incredible speed and small size in compare to other libraries. Svelte is ♡


.NET Core & Ruby (on Rails)

I'm a frontend developer yet I have more than 11 years of experience in BE development. When I need to build an API for my projects, Node.js, Ruby and .NET Core are my choices.
