Software Crafter, currently senior consultant & CTO @ Zenika Montréal

I am a passionate developer for more than 14 years. Convinced that working software is good but not enough, I work with my clients mainly as a Tech Lead in agile projects to build well-crafted software. I have worked as a Tech Lead for high stakes projects such as government websites or international sports tournaments websites.

I also like to share my knowledge and therefore I am a trainer on software development practices such as Test Driven Development, and I regularly present talks in meetups or conferences such as Devoxx France.

Finally, I am a co-organizer of the Software Crafters Montreal meetup and co-founder of the SoCraTes Canada conference.

I can help you if you have one of these symptoms:

  • Difficulties to add new features to an existing legacy codebase
  • More time spent to fix bugs than to add new features
  • No clear definition of what clean code or software quality are
  • Not sure how to write good automated tests and which kind of tests you should write
  • Too much technical debt
  • Having still the same issues even when working on a codebase started less than 1 year ago
  • Willing to create a well-crafted software that you won’t throw away in 3 years

Server-Sent Events with Nuxt.js (Vue.js) and Nginx proxy

Suppose you have a Nuxt.js (Vue.js) application which calls a backend and which is behind a Nginx reverse proxy. If your backend stream Server-Sent Events (SSE) using text/event-stream content-type, you may have these errors: 504 (Gateway Time-out) or ERR_INCOMPLETE_CHUNKED_ENCODING (in Chrome). If you want to make SSE works with your Nuxt.js application which is behind a Nginx reverse proxy, you have to do 2 things : Enable long running connections in Nginx Add these lines in your Nginx configuration:

How to properly encrypt data using JPA converters and Spring Data JPA

TL;DR: all code is directly available on GitHub: https://github.com/damienbeaufils/spring-data-jpa-encryption-example Each time I want to encrypt entity fields values with JPA converters, I end up reading this blog post. This example is clear and functional, but has no unit or integration tests, and I thought the code could be more decoupled to avoid duplication when having multiple converters. So I wrote an example using Spring Boot and Spring Data JPA, with a User entity which have different fields: id (a Long), firstName (a String), lastName (a String), email (a String), birthDate (a LocalDate) and creationDate (a LocalDateTime).

Implementing a SOAP client with CXF using Play Framework 2.x

TL;DR: if you want to skip the tutorial, all code is directly available on GitHub: https://github.com/damienbeaufils/soap-client-with-cxf-using-play EDIT June 2016: code on my GitHub repository updated for Play Framework 2.5! Play 2.4 version is still available here. I was working on a new client product, and I had to plug a web application built with Play Framework (and then sbt) to SOAP web services. How to do it? The need: be able to generate Java classes from one or many WSDL files, and use those classes with Play 2.
