Proactivity defines the way we work, we take user needs and help translate those into solution features; here’s how...

We take your needs and translate them into "Product Features." We understand that it is difficult to get upfront clarification of every detail, so we don't shoot for that. We work with you and embrace change to get the best solution.


We help you to prioritize the "Product Features" list.


We take a subset of "Product Features" at the top of the prioritized list and divide them by tasks.


Once a subset of tasks are ready, we present them to you and release/deploy to staging environments so we can gather feedback the soon you play with features the better feedback we get looking for the perfect solution. It doesn’t matter if the subset is ready a few hours after release planning, we deploy so you can play.


The steps should be short to give the Software Professionals enough time to produce a quality product, get feedback and continuously address and embrace change.

At the end the customer will receive a solution tailored to their specific needs and with low bug rate as those get addressed on each iteration.

Version control is important to determine ownership and traceability of all the participating artifacts.

Every Monday let's meet for an hour with the team to determine that week’s priorities

Tuesday - Friday let's meet for 5-10 minutes with the team to assess team’s work and answer questions

Every day let’s talk and help us review the features we deploy to get timely feedback

Our Apprenticeship Program?

“A recognition from the President of Costa Rica for our apprenticeship program”

When our senior members started their careers they were thrown to cubicles with

computers and were given big piles of documentation and were told to create programs...

and of course they did...

but were they following best known methods? were they following best practices?

Probably not, and that's why we want others to learn from our mistakes.

Pernix apprentices learn from others; they don't work on projects,

they basically learn what it takes to create software within an agile environment.

We will pay you to learn.

What will you learn?

  • Powerful methods and technologies to build software.
  • Actively participate with our consultants on challenges that develop your skills to create quality software.
  • Clean Code and software best practices, and state-of-the-art technologies.
  • Share your knowledge through books, blogs, open spaces.
