What we do

White Prompt is a unique hub of IT experts that love realizing new exciting products. We carefully select languages and tools that help us generate clean, scalable and maintainable code. Technologies evolve every day and we evolve with them, keeping our eyes open to new technologies and our minds to new ideas. Depending on the project we would recommend agile technologies such as Python, Node and React or more enterprise oriented such as Scala, Java and .Net.



White Prompt specializes in developing new products for Startups from the ground up. We have wide experience generating wireframes, adding the needed Graphic Design and UX, implementing backend APIs, Single Page Application front ends, setting up the hosting infrastructure and monitoring production.



We have vast experience implementing distributed systems with strong non functional requirements such as  high availability, elastic infrastructure, Polyglot Microservices, Service Oriented Architecture, Message Broker interconnectivity and Multi-site deployment.



We have a great team of Cloud Engineers, DevOps and SysAdmins specialized in Amazon AWS Services. This is clearly the largest and most evolved provider that exists today, with a huge list of services ranging from bare servers to complex orchestration. We’ve been building complete environments with AWS for years now, and we can proudly say our knowledge and experience with this vendor is really extensive.



White Prompt has two development centers in Latin America. One in Buenos Aires, Argentina and a second one in Porto Alegre, Brazil. White Prompt employees work from 8 am to 5 pm Eastern Time, the time overlap your project very much needs. Frequent flights for face-to-face workshops and constant video chatting makes the distance fade away. All White Prompt employees have 7+ years of experience developing code and are perfectly fluent in English.



It is proven that Investing in quality pays off by itself in no time. The average bug steals 2.5 hours of your team in average. Sounds like too much? Think about the time invested in understanding the bug report, reproducing it, installing the right version of code where to fix it, finding the bug, fixing it , testing and redeploying. It is brutal. When you implement an automated regression test suite you are saving yourself from all that burden, while improving your coding productivity and your customer experience.


Micro Services As A Service

Users, Privileges, Profiles, Single Sign On, Credit Card Gateways, Resource Allocations; all sort of functionalities that get implemented over and over again in projects. The alternative is to include a set of third party libraries that you need to adapt and maintain or registering into multiple SAAS that are overkill for what you need. White Prompt has developed MSAAS (Micro-Services As A Service). A set of Micro Services you can opt-in for your project. Our micro services are small, light and easy to use. You can connect your own micro services with ours via Rest or leveraging our message broker.
