DDI Development worked with a digital agency to build a custom platform for boutique management consultancy. The project was initially passed on to DDI from another company due to workload issues. DDI's main role was backend and database development, utilizing PHP, JavaScript, and Angular JS within the Symphony framework. A separate designer was used for the frontend coding and implementation. The project cost approximately $10,000 and was completed in December 2015. The agency founder expressed satisfaction with DDI's work and mentioned plans for a new project with them.

For an education startup, DDI Development created a tailored e-learning platform. The startup, which provides customized e-learning platforms for different countries, specifically underdeveloped ones, needed a long-term partner to handle complex development work. DDI was responsible for backend and frontend development, custom coding, API development, quality assurance, and project management. The team used Python, Django, PHP, HTML, SQL, and JavaScript for the project, which cost around $300,000 since 2011. The startup is happy with DDI's involvement and continues to work with them for bug resolutions, new features, and system performance improvements.

Bluehack srl, an e-commerce community-driven brand, hired DDI Development to fix problems on both the frontend and the backend of their site. DDI's tasks included web development and quality assurance. The project cost about $50,000. The CEO of Bluehack expressed satisfaction with DDI's work, stating that the tasks were always executed perfectly and a trusting relationship was built. He anticipates a long-term collaboration with DDI.
