Hello,
My name is Viktor. I'm developer (more than 10 years of experience in a field of web development, US and European companies) and owner of a small dev comapny in Krakow, Poland.
We are developers and work with basically any type of coding, mostly focused on PHP/.NET and JS/HTML/CSS. But also have experience in doing Cordova, React Native and native Android and iOS apps.
For your project - we should be able to create, but first need to look at your existing website to see how much it will take and what else is needed there.
In our work, we use GIT to keep source codes and may set up a demo server for you so you can see changes we do ASAP and without deploying them to live site.
Additionally, I'll send you reports once in a day or two showing hours spent and description of job that has been done. So, you can control your progress and budget easily.
Before some new feature is done, we'll also send you possibly solutions (if we see more than one) with pros and cons and estimate. So you can choose best approach you need.
We can discuss our options in more details in chat if you are interested in my offer.
Looking ahead for a great experience working together!
With regards
Viktor
