It has met all my expectations. The format is perfect, blending theory and practice. Programming with others opens your mind and generates very interesting debates. Now I can say that I have a Swiss Army knife to face the Legacy monster.
Luis Ruiz Pavón
Principal Software Engineer at Eventbrite
-
A practical course based on a solid philosophy. The team left with more eagerness to work on a legacy. The next day we started improving our practices. Huge success!
François Delaunay

-
Fundamental course to raise the team's awareness of Legacy Code issues, which are not always seen as such, while aligning the team on how to address them. Suitable not only for working with Legacy Code but also to stop generating it!
Jorge Sánchez
Software Architect at Digi Spain Telecom
-
The course was a turning point for daring to do things differently: with more confidence and more quality. A year after the course, we have noticed a significant improvement in the code and the methodologies we apply.

An essential training to face that great monster known as legacy code. With training like this, it's impossible not to be passionate about our work.

We came out recharged!. Working with Legacy is not easy, but thanks to this course, the team now shares tools, vocabulary, and a different perspective to tackle it. We are delighted.

Ha sido una oportunidad magnífica para aprender, trabajar como un equipo, compartir y validar ideas. Es muy práctico y se favorecen las conversaciones sobre distintas soluciones a un mismo problema. ¡Salimos con ganas de mejorar nuestro código!

Methodology
Nowadays, anyone can read a book or watch a video, but the really difficult part is putting what you've learned into practice. That's why, in our course, we want students to spend most of their time practicing and not listening to theory.
In pursuit of quality and satisfaction for all attendees, we believe it is essential to have two senior instructors. This allows us to have enough availability to provide personalized help while students program.
We strive to maximize learning. To achieve this, we create a dynamic environment (Flow) by working in pairs, short exercises, quickly resolving doubts, jointly discussing different solutions, and providing very close support.
From our experience as teachers, developers, and entrepreneurs, we understand the challenges of software development. Having taught over 60 courses to more than 800 students allows us to know the needs of the students and pay attention to every detail of the training.
All of the above guarantees our goal of ensuring you are satisfied, acquire the necessary skills to transform your way of developing, and start writing sustainable code.

Frequently asked questions
Who is it aimed at?
To teams where automated testing is not the usual practice.
To companies that add functionality very slowly and/or have many incidents.
To back-end, front-end, or mobile programmers who work with legacy code.
What is the level of the course?
The course level is intermediate. It is aimed at people who program professionally.
Being a very practical course with a lot of debate allows us to adapt to the level of the attendees.
This course will be less beneficial for those with good knowledge of object-oriented programming, clean code, and who write automated unit tests daily.
Can the course be subsidized by FUNDAE?
Yes, the course can be subsidized through FUNDAE.
Currently, 208 € can be subsidized per student.
We provide all the data for its online submission, but we do not process it.
Why should the whole team attend?
Bringing the whole team together, in addition to generating team building, allows people who usually don't work together to collaborate.
Throughout the days, we encourage dialogue and debates among the team, which help align their vision.
Nothing better than two days of training to motivate the team.
How is the course developed?
The course consists of several blocks of two hours.
Each block starts with a brief theoretical introduction.
This is followed by an exercise done in pairs where they put into practice what was covered in the theoretical part while the trainers provide constant feedback to the participants.
The block ends with a group debate, where the participants share what they have learned and we have discussions all together.
Can I sign up by myself?
The course is designed to be delivered in companies.
We also offer open courses where anyone can sign up.
Sign up and we will inform you about the upcoming courses near you.
What material do I need?
You only need to bring a computer with the development tools that each person uses installed. Ideally, the course should be taken on the same machines that the team uses in their day to day and Docker.
In person, a room with a projector or a large screen and a whiteboard for writing is needed. The ideal setup is to have a computer with two screens, two keyboards, and two mice for every two people.
Remotely, a microphone, headphones, and webcam are needed for each participant.
And after the course, what?
The exercises done in the course are specific for learning one concept at a time.
During our day-to-day, we face much more complex problems and with code in worse condition.
Therefore, after the course, we offer support to your company to help in transforming your legacy into something maintainable.
