The fitness education company web-site


We negotiated really fast that time. The reason is quite simple: the client came to us well prepared and all the structure and content were ready. So we took all the copy, images, collected specifications with instructions, and pulled into production. The most time took the UX UI design works. We worked hard together with Alex(client) from day to day, for about 2 weeks,

until we got the best unique design for the future site. The rest job was handeled by development department, who took PSD files, and sliced them into HTML. The admin panel on the back-end implemented with Wordpress, and that made maintanance of the content pretty easy for client. Project completed successfully and in time. After the main project development, Alex came to us to small additional works, we believe this demonstrates his satisfaction with our service.

Home-made meals ordering platform in Amsterdam


We picked up this project on Upwork. Gideon is the project owner, was nice in communications and provided very clear instructions to his tasks. On the first stage, our main task was dubug, bug fix, and project full complete before release. As that always happens, not too much reliable developer left unfinished project face-to-face with his owner. And we did much work to bring many

things to its logical end, did a deep optimisation, refacktored large pieces of the code. The deadline was strict, but we delivered!

Later, the it launced, first customers provided their feedbacks, and overal imagination took place, Gideon came back to us with the full redesign process. Again deadlines were tight, but we complete all the development, and now more and more happy customers can taste awesome home meals in the Amsterdam.
