App Experience Optimization
When you develop a SaaS app, you aren’t just selling a service. You’re offering an experience built around solving problems and simplifying lives. Simplicity and efficiency are equally important, so we optimize both the backend and the frontend during and after development to deliver an effective app for every user.
Intuitive Interfaces
If using your product is frustrating, users are more likely to shift to a competitor. When we work with you, we’ll give you actionable advice to keep your app intuitive, relevant, and reliable for every user.

Robust Tech Stacks Powering Our Scalable SaaS Applications
Behind every SaaS app developed with Big Human is a robust tech stack that factors in your needs, goals, and user base. Our full-stack development services deliver a unique, customized system, regardless of the services or support you need.
Cross-Platform Frameworks: Flutter, React Native, Ionic, Xamarin, NativeScript
Without an appropriate cross-platform framework, users attempting to download and use your app may deal with incompatibilities depending on their operating system. To eliminate this issue, we use cutting-edge cross-platform frameworks such as:
Flutter
Ionic
.NET MAUI (formerly Xamarin)
NativeScript
Before recommending a specific platform, we’ll discuss the benefits and drawbacks of each choice to determine which will best suit your project.
Cloud Platforms & Services: AWS, GCP, Azure, Firebase
The cloud platform hosting your app plays a vital role in your program’s speed, scalability, and infrastructure. We can use:
Amazon Web Services (AWS): This is the world’s biggest cloud platform and offers on-demand access to hundreds of services.
Azure (by Microsoft): This provides access to additional storage, computing, analytics, built-in AI, and more.
Google Computing Services (GCP): This offers infrastructure services, application add-ons, advanced data storage, analytics, access to AI services, and more.
Firebase: This is a simpler version of GCP that offers fewer features but higher performance. If you need additional services, you can use Firebase alongside GCP.
Backend for Mobile Apps: Node.js, Python, PHP
When we are programming the back-end of your SaaS app, we’ll choose between Node.js, Python, and PHP. Each has specific strengths and technical abilities, so we take the time to help you navigate which choice is ideal for you.
Native Development: Swift, Kotlin
Databases for Mobile Apps: PostgreSQL, MySQL, MongoDB, SQLite
Your SaaS needs a secure database to store and retrieve data. However, different database structures offer different benefits. With options such as PostgreSQL, MySQL, MongoDB, and SQLite available, we’ll choose the appropriate option during development.
APIs & Integrations: REST, GraphQL
Your specific APIs and integrations determine how your systems respond to internal requests. We use REST and GraphQL during development. REST is stateless and can be used for broad requests, while GraphQL is slightly faster and better tailored to specific requests.
App Testing & QA Tools: Appium, XCTest, Espresso
Before your launch date, we’ll perform several QA tests to verify that everything works as intended. We use XCTest to verify that the most minor units operate properly, Espresso to check your Android-only features, and Appium to test Android and iOS native frameworks.
DevOps & CI/CD for Apps: Jenkins, GitHub Actions, Bitrise
SaaS apps change regularly. That’s why we use CI/CD to test, monitor, and address errors in code updates before integrating changes to your SaaS. With top-of-the-line tools like Jenkins, GitHub Actions, and Bitrise at our disposal, we can monitor each new feature to bring you closer to your goals.
