FinTech App Development Case Study

Big Human served as TD Ameritrade’s agency of record for nearly 10 years. Throughout that time period, we worked on iterating the brokerage firm’s iOS and Android apps and helping to bring them into the era of 21st-century innovation — among other projects. One notable chapter of our partnership was the creation of the mobile app thinkorswim, a platform where traders could access TD Ameritrade's services. We built the app's UX so it felt intuitive, and we also expanded the customer support capabilities to include live screen sharing.

Quality assurance


Our developers and designers work with your team to understand the business needs of your FinTech app. What are your goals and objectives? This helps us integrate the front and back-office services that will best suit your FinTech app.


Our FinTech app developers will work with you through concepting, wireframing, user testing, quality assurance, and more to ensure scalability, security, and performance. Once we determine your stack of services, we begin the development process. This is done in sprints determined by your priorities, and there’s flexibility when and where needed.


Protecting the entire infrastructure is our top priority when working on FinTech app development projects. From the back end to the network hosting it, our development team will employ the latest and greatest cybersecurity solutions and protocols to prioritize your application’s security.

Quality assurance

Our agile process allows us to pivot and provide QA as early as possible. We polish the product throughout (not just at the end) to ensure we meet client expectations and user needs.
