Case study

Research team by exploring numerous individuals, families and single mothers, collected and processed an impressive set of data organised by various parameters and factors in multiple dimensions.

In the middle of 2022, Sonder Collective made a decision that the results and learnings of this wide-scale extensive research are ready and can be made publicly available. The first thought was - let’s create a web service available to anyone around the world. One basic requirement was to make each household data segment easy to explore and able to compare various segments to confront differences by categories like health outcomes: reproductive health, pregnancy, child health, nutrition or various vulnerabilities: individual, household, community, and healthcare.

Pathways is a project different from any other as it has a huge social impact and touches personal health and family aspects across different countries and social origins

The project aims to make health outcomes and their segmentation visible. Pathways is a platform with knowledge from the research and learning about health, family aspects, women’s well-being and their families. At the heart of Pathways is a desire to understand the nuanced factors that constitute the socio-economic, environmental, and cultural vulnerability of women and their children to poor health. We have created a platform that allows you to view and compare these multidimensional sets of data.

Services we did for them:

1. Research:

This stage consisted in doing research, understanding the product and choosing the technology in the context of the platform maintenance costs as well as the ease and speed of backend implementation. The fontend had to be custom to reflect the design, specially prepared for it to be able to clearly show this data.

2. Design and development:

Close collaboration with the international design team to find out the best UX using our knowledge from our practice and know-how. As a result of this cooperation we have created a dedicated design system in Figma.

3. Implementation:

  • Headless Strapi CMS structure as a data source provider for Angular frontend application
  • Angular frontend application with a requirement to be open for a future switch to any custom-written backend service
  • Heroku setup including Gitlab CI/CD as a cloud infrastructure provider
  • integration for analytics
  • To protect the website from a e.g. DDoS attack we have added CloudFlare in the front of the service

Where it works:


Project development

First step

Our first task was to find out a solution, a technology that will be flexible enough to, in a relatively easy way, create data structure provided by researchers and at the same time should be easy to populate and moderate content by the same people. Another constraint that we had to face was tight dev time and budget. Combining these basic requirements we decided to go with headless CMS. Headless CMS provides lots of advantages: easy-to-use UI for non-tech people, flexibility in customisation of data structure, and ease to set up and deploy instances.

Second step

As the project has huge potential to evaluate and grow we decided to design and develop a frontend application using a complete custom approach with Angular. We designed and implemented an Angular application with a mandatory requirement to be open for any further backend service integration. Why is that? As headless CMS is good enough at this phase and covers all our features, in the short future this may change. We wanted to be sure that we would be open to developing a new backend service.  It might be a completely custom one that will be easy to integrate with the frontend Angular app.

Third step

The last piece left to make the solution live and publicly available was the infrastructure. Pathways project was at this moment informational application where visitors can compare segments, without for example UIM (User Identity Management) or other sophisticated data processing that requires dedicated solutions. Taking all these requirements including the cost of running, we decided that the most accurate cloud provider is Heroku. Thus with a few lines of Terraform IaaC and Gitlab CI/CD, we have created a complete pipeline and cloud infrastructure that host our Pathways project.

Fourth step

As security is important obviously at the very front side, under the hood we have used CloudFlare. It is a service that in basic form provides numerous protections like a DDoS out of the box, free of charge. We strongly recommend using the CloudFlare solution as a basic protection wall if you still do not use it. Our goal and intention are to create a reliable and secure solution, which is why we maintain the platform and update any security lacks.

Challenges to overcome

Developing websites and web applications requires expertise in multiple areas, including user experience, functionality, accessibility, and security. During the development phase of projects, our team of experts faced intriguing challenges and found great solutions to them. This is where you can dive into the details!

Designer, Co-Founder & Board Member
Working with EliteCrew suited our complex project set up very well. We had many uncertainties to solve and timelines were unclear, but Elitecrew managed the development so smoothly alongside our design process. The interaction with the team was always super positive and friendly. Their independent work style and continuous communication via slack really made a difference in our busy schedules. Thank you for being such a reliable partner in this project.

Quality Assurance

I have participated in the project from the very beginning, it is definitely a project with potential. I have the pleasure of taking care of the quality of this product, it is demanding in terms of frontend and backend testing ([Backend testing] A big challenge and at the same time something new and interesting for me was to solve the problem of how to solve the problem with the complex structure of the database built on strapi, finally, I solved this problem, which resulted in a new skill that I will certainly use in further work.). The product itself has a very clear and intuitive graphical interface, it is also a well-structured database. I am very happy to have the pleasure of working with this product, thanks to it I can bring many new improvements to current and future projects :)

Marek Wrzosowski

This is the first in my entirely carrier so innovative initiative, that engage so many, so different to each other disciplines to explore social, cultural and environmental risk factors impacting Reproductive, Maternal, Newborn, Child Health and Nutrition (RMNCH+N).

It combines research done across Northern Nigeria, Kenya and Bihar, India to further expertise analyses of researched data to in final step exposed ready to use results via web platform to global health practitioners to stratify households based on social, economic, cultural and environmental vulnerability factors that are associated with poor health outcomes.

Krzysztof Kura
Back-End Developer

During the implementation of the project, I act as a backend developer. Working on the project allowed me to expand my knowledge due to the fact that we use tools with which I had little contact so far. I believe that the described project is of great value because it serves people who really need this help.
