Backend & API Services

Great mobile experiences depend on reliable backend systems, and while horizontal slicing works, we've found it advantageous to work full-stack. At Sapling Mobile, we design, build, and support backend APIs that are secure, scalable, and resilient under real-world conditions. Our teams have delivered production APIs for some of the most respected brands in retail and beyond, deploying on AWS, GCP, and Azure, as well as self-hosted environments. We design backend systems that scale, but more importantly, we validate that they hold up under stress. As bots and automated attacks become more sophisticated, especially with advances in AI, APIs are constantly being probed. Our goal is to identify weaknesses early, long before your users (or bad actors) do.
