"I am more than happy of my choice to hire this freelancer. Communication was excellent and each part of the project was discussed in detail before work had began. Even better, the freelancer was proactive in trying to understand what I wanted exactly as an end result and the level of polishing that was expected. Deadlines were all met and whenever there was any kind of a setback, I was informed immediately. I was never in a situation of not knowing where the project currently stands. I was informed on stage of the project, which allowed me to have minor tweaks in midway and now the final deliverable is even better than what I had planned. For bigger changes outside the scope of the contract, I was sufficiently informed of my options and now I can better plan my next versions. The whole project consisted of a cross-platform React Native App, that was dynamically updated from an Admin Panel. The result was a lightning fast database and changes that took less than 3 seconds to appear inside the app. Both the iOS and Android versions work great and behave like any modern app. APK size was less than 30MB and the app is overall very fast, so the project is visibly cleaned up from any possible junk code or files. The quality of the deliverable was simply excellent."
