Hi, I am Pau Trepat

Pau Trepat

Software Crafter at Lifull Connect

I am a passionate software crafter with experience in backend and bigdata. Over the last few years, I adopted different roles to bring value where the company needed it. At each change I have tried to take care of two very important things to me: learn and make an impact.

Due to the apprenticeship program, I rediscovered how I love to teach and help others to growth so I’m focusing to get more knowledge and learn how to transfer it.

Agile Development
Team work
Critical thinking


Cloud Computing
Cloud Computing

I’ve worked mainly on AWS using its services for big data purposes. Also, I’ve used some GCP tools but just to integrate with them.


Mostly I use docker to reproduce local environments and to avoid that have to install build tools on every machine.


Main operating system for development. Capable of writing bash/shell scripts to automate tasks.


Experienced in git based development using Github (for personal projects) and Gitlab (for work). I prepared and trainned workmates to migrate from Subversion to Git.


The main language for professional and own development. Capable of writing scalable, testable, and maintainable programs. I worked with most popular frameworks to apply IoC and develop an HTTP API.


I’ve learned this language two years ago to write Spark software and was my first heavy contact with functional programming. Currently learning it yet.


I’ve used this language for some professional projects when the organization required help in them. I can write testable and maintainable programs.


Since I discovered it in 2014 (and had a mind blown) I’ve tried to apply and refine it at every opportunity along with refactoring.

Software Design
Software Design

I read about OOP, software patterns and architecture. I get the best learnings by doing and iterating, like design itself.

It was my first contact with ideas that nowadays I consider essential for software development. Agile practices and values; techniques such as TDD and continuous integration; and a shallow understanding of what is value.
Also, we had to deal with the technical debt that we generated at the early stages. Due to this experience, I started to take consciousness of it and to learn about how to avoid, control or reduce it.
