Custom software backend development, for enterprises and start-ups


Scalable system architecture

If you build something, build it in the right way, it will be one that easily scales. We believe that building smart solutions means smart choices on architecture, processes, and performance. That is why we chose Scala. We build tailored systems that last for years and can be understood by anyone who tries to look at the code with the same values we share: expressiveness and correctness.


Advanced web applications

Our cross-functional and cross-domain team, experienced on many different projects can deliver applications even for the most challenging tasks. From payroll solutions, blockchains, to AdTech platforms.


Full-stack software development

Apart from the backend, we can take over frontend development, testing, DevOps support, and even Project Management.


Training, workshops, consulting

We offer Training, to help you educate your team. We offer workshops for product teams to prepare the right specifications and consultations/audits to make sure you use the best software in the right, most efficient way.

E-learning Platform Optimization

The client expanded the development team in an established technology with a strong team of developers, alleviating the challenges and costs of recruiting at scale in a competitive market in San Francisco.
Adtech data retrieval, processing and distribution process

Adtech Data Retrieval, Processing and Distribution Process

We re-wrote the process of data retrieval, processing and distribution (ETL) in a streaming manner. This allowed us to reduce the costs, as we no longer needed a Spark cluster, with only a single machine required to handle the same or larger amount of data in a resource-safe manner.
