Background Pokojowo was a small start-up founded by Seth McMillan and Beata Kolodziejczyk in May 2020 in Krakow, Poland. Their idea was to make mental health treatment easily accessible and affordable by building a digital platform, something both comfortable and important in the Covid era. Client Pokojowo is a Poland-based mental health practice focused on expanding access, affordability, and user experience for their patients. They launched a new digital platform to revolutionize mental health treatment by quickly addressing mental health problems through text chats and online sessions to engage their clients and reach successful outcomes in a whole new way. The platform also offers suggested content along with the latest global news in mental health – all within the application. With Pokojowo, clients no longer need to make an appointment to communicate with a qualified psychologist – just start a text message within the application at a fraction of the cost of a traditional session. Challenges When the clients approached Symphony Solutions, they only had high-level application features description but did not have any technical expertise to develop a full-scale solution. As the start-up participated in a pre-accelerator program, timeline for presenting the ready-to-use product was aggressive, and technical challenges required a champion team of full stack developers. Solution Based on the client’s requirements, as part of our cloud native development services Symphony Solutions provided a unique solution that used as a basis AWS serverless approach. AWS has a full set of instruments to make a scalable and secure application. It allowed to develop a product rapidly, which was especially critical for Pokojowo. Being a start-up, optimizing infrastructure expenses was one of the client’s priorities. And with pay-as-you-go, they would be able to understand clearly how much is spent. As a healthcare product, the solution had to make the security of their patients’ data a priority.
