We hired Yellow to act as our web development team, helping us deal with the new web functionality needs of our clients. Their team was the most skilled among other vendors we considered.Their main tasks were to optimize web speed, website development and updating, and bug fixing. Their performance was great: site speed was increased by 10 (Google speed optimization), which enhanced user experience and SEO.Language and time difference are never an issue, we communicated smoothly via Skype and email and everything is great.
