// Our expertise

Technologies we use in production

We are opinionated about our technology choices, selecting tools with the right trade-offs for production software, not the most popular tools. Here is our current stack with the rationale behind each choice.

Years reflect our engineers' hands-on experience with each technology, including work before Simplileap; project counts are Simplileap deliveries.
