Quality House.

Quality House (https://qualityhouse.com/) provides testing services to IT
companies of all sizes and types both from Bulgaria and abroad. The company has
been providing behind-the-scene assistance and improving software quality since
2004.
What we do, is providing the needed expertise and capacity to other companies
so they can meet their goals both in terms of software quality and deadline. To
back this, all our Software Test Engineers are ISTQB certified and act as a natural
extension of on-site QA teams or build entirely new ones.
Apart from the outsourcing and consultancy services, Quality House is a trusted
provider with a rich portfolio of professional courses and an accredited training
provider of ISTQB courses as well.
