The most amazing...
...redesign I've worked on is a Flash-based component framework that was modernized using HTML, CSS, build processes, and cutting-edge techniques.
Work Experience

- Collaborated with the DevOps team to manage the project and dependency release schedule.
- Operated daily with XML documents and learned a bit about writing XSD to validate them.

- Designed and developed a Flash website for a major shopping mall and, in a future opportunity for the same client, I built an HTML and CSS version.

- Worked on print designs for major local companies.
Experience
Guest-Rm
The website offers users the possibility to build a trusted network of friends so they can reserve each other's homes, with the unique feature of having a one-time fee of $20 per reservation, no matter the number of guests and of nights they stay.
Together with the Toptal designer, Csaba Házi, we went back to the drawing board and completely redesigned and redeveloped this existing website with many more features and a better user experience.
