Fresh new landing page


One year ago, we did a quick page to describe Welean.it project. Since we put it online, concept has changed, and we are convinced the idea is great and Welean.it will continue. So we have taken a moment to remasterized the homepage, trying to explain the concept and make a clear and fresh page.


In Welean.it team, we don’t like bullshit. We are mostly IT people, and want a clear and clean message. Thus, we started the page with a clear subline branding “LEAN CODING WEEK-ENDS”. Then, a big, white, short sentences box.

We took time to describe the concept further, and to give an overview of past projects. However, we didn’t explain too much, as the blog answer everything else.

In fact, this landing page took less than an afternoon to dev from scratch. It will probably need small fixes – and evolution – but seems to be good enough for production. We will iterate in the next days to make it perfect ;)

You can get the whole page source code on github, release under MIT licence.



The gamping project

Gamping is a project done during the first Welean session.

The aim of the project was to restart an existing website from scratch, with a new technical stack. Thus, the project owner – Joseph – will be able to raise funds and grow his product to become a real marketplace.

What has been done?

Below some screenshots of the final website. It has been done from scratch, by 3 developpers (Olivier, Thibaud and Tilap). Half of the job done was pure technical

See the live demo of what we did and feel free to have a look at the sourcecode on Github.

You can also read the Olivier feedback about Gamping.

Welean Session #1: Olivier feedback


Olivier – Evaneos lead dev – share his feedback about the first Welean session :

I’ve worked on Gamping project. There is already a working version of the website. However, the technical stack was too basic to evolve and to become a commercial marketplace. Joseph, the project leader, is currently raising funds and need great technical fundations to grow up.

So, we wanted to rebuild the most existing features but on a new, clear, efficient technical stack.

Technically, we started from Silex, the Symfony base framework. We have put many improvements (YML configuration, Depency injection, …) and called it Pyrite. We work with some open source tools we have at Evaneos: our model engine, called Berthe, and our i18n translation base.

We have spend hours working on pure technical stuff, and I think it was a bit far from the Lean Startup method. However, we achieve the main user funnel: homepage, map to display available places, place details, and stuff to create/edit a place. Eveything working in many languages.

I’m proud of what we achieve, even if we spent a lot of time on pure technical problems and didn’t succedd to recode all the website features. The atmosphere was really cool (it reminds me the LAN party atmospehr), and even if I have coded 2 days in a row, it was not working for me, it was passion.

I hope next time we’ll be more to challenge higher!

Welean Session #1: Pascal feedback


Pascal – Evaneos Market/dev – share his feedback about the first Welean session :

It was really interesting to work on the project pitch. It was short, and offered a large panel of solutions. We had to work on it to scope the project better.

It was a really good experience, with a great, friendly and hard working atmosphere. I was surprised by the quality of the final product and the technical high level people have.
I regret :
– not to be technical good enough to participate more, but I’ve learnt a lot;
– the final product delivered still need some features to totally work.

Welean Session #1: Christophe feedback


Christophe – Evaneos developper – share his feedback about the first Welean session :

Welean was really cool, motivating, and I’ve learn a lot. The final product (Creative reporter) works fine and is online. I have discovered new tech and hope we’ll do another one soon!

Regarding Creative Reporter, we have worked with a cool tech stack : nodeJS (express, mongodb, jade, stylus and passport), AngularJS, mapBox, TileMill, cloudinary… I’m really proud of the result for a 2 day project!

The main difficulty was the deadline. We absolutly wanted to deliver a product that works but had to change the final features target many times coz of technical limitations.

Welean Session #1: Yvan feedback


Yvan – Evaneos CTO – share his feedback about the first Welean session :

WeLeanIt is a chance to start from scratch and to dive deeply in a project for two days ! Coding during 48 hours in a row with people as enthusiastic as I am allow to :

  • re-discover people I work everyday with, but in a different context,
  • go further than ever in product and tech,
  • learn a lot, really,
  • share idea and knowledge,
  • eat KFC food and drink RedBull again!

The next session? More teams, to completly achieve a product and to put it online! I’ll be in!

First session !

The projects

Thanks to twitter, we received more than 30 project ideas. Some basic ones (building a blog), some really challenging (3D app), some based on huge data (a website to compare price of every hotels)… We kept 2 of them.

  • Create a place to share geolocalized quality pics for advanced photographers.
  • Create a website where a closed and advanced user community can publish pictures of their travel.

  • Build a new version of Gamping.com.
    Gamping is a website to share and rent garden place for camping. Bright idea, but build on a really ugly tech stack, and we can provide new features idea.

The place

We found a really great place for 2 days: DojoCrea invited us to their open space!

The date

Welean#1 will take place on December 14th and 15th.

The Welean concept


So, as we told previously, we’re gonna dev a product in only 2 days.

After a quick brainstorm, we decided some rules to achieve that challenge. We know it won’t be perfect the first time. But we’ll iterate on next editions depending on the feedbacks. Yeah, we love agile way of work.

What can we dev?

We have lots of product ideas. But for this first Welean edition, it should be nice to develop for someone else. Someone who has idea, but cannot do it by itself. Someone who is entrepreneur, but cannot achieve his dream ’cause he cannot code.
And as it’s the first time we do that, we want to keep benefits of our job exepreience. We will do a web app, and stay in the field of travel. So, we’ll be able to help – on tech or on feature idea.

But where to find people with idea? Let’s try on twitter! Crowdsourcing the ideas should work fine. We hope people won’t obviously keep their idea (and never do them…).

How to work the best?

We will dev in only 2 days. So, we need to focus, we cannot work in big team, need a place where we can work day and night…

Even if we have a really cool office in Paris, we will escape the daily work and find a nice place, changing our minds and habits.
We will work with 3 or 4 people max on a project. We’re convinced that teamp with more than 5 people will require coordination, and we have no time to waste. So, 3 or 4 seems to be great.

The final target

What about the product at the end of the session?

We ant to give it to the project leader. We also want to share the world our experience. So, the code will be release under an Open Source licence – meaning anybody can get the code.
Moreover, to share our work, we’ll try to do a demo website for each project. It will be difficult (and have a cost for hosting), so we are not sure it will be possible. But let’s try it.

Next steps

We need to:

  • grab the idea people will submit;
  • select one or more project;
  • select the teams;
  • find a place;
  • find a date.

Welean: the beginning


The crazy team background

At Evaneos.com, we love products, innovation, and have a strong development team.

Even if we are only 5 developers, we already manage many applications – not only the Evaneos.com frontend website. We work on the other countries : Deutsch version, Italian version and the Spanish one. We also have 40 other public websites giving tips and advises to travel around the world.
It’s far from the whole things we do. As Evaneos.com put travellers and local agents in relation, we create web tools for local agent too, and many internal apps to find, follow and help them to communicate and give the best they can to our customers. And do not forget payment app, message box tools, map tools, …

Yes, you easily understand: at Evaneos, product development is not only a tool for business. It’s a passion.


Working hard everyday is cool, really, with features, design, and tech challenges. However, we often want to do more: discovering new technical langage, test new product idea, or simply to change our job for one or two day.

So, we have this idea: what about developing a product during one week-end? As we work everyday with scrum method and the background spirit of lean, it seems to be possible.

Here we go

So? Ok, let’s go. We’re gonna dev a product in only 2 days.

Next? We need to scope the way to achieve that.
But we’ll do.
