Achievements and Collaborations

Housing Submissions Center of Quebec (2016)

This is one of my accomplishments on which I spent the most time:, which is a redesign and rebranding of A business directory for entrepreneurs, but also solicitations, property for sale and much more.

I developed this site from A to Z (except the used libraries): Find the name, create the logo, create the user experience, program the web application, integration of the visual, migration of the old architecture of database to the new, URL redirects, etc.

An interesting feature of this website is that I developed a web robot (Contentator2000) in multi-threaded Python who will pick up to the minute the property to sell on various sites of real estate agencies in Quebec and displays them on the site, with a daily update.

This web application has been designed with Symfony3, Doctrine2, PostgreSQL, Bootstrap, Python, Debian GNU / Linux and NGINX.

English and French, this website is made from free software electronic Prestashop 1.6. The payment methods offered are PayPal, Moneris eSelect Plus and INTERAC.

My job has been to train employees in SEO writing, The GIMP, managing social networks and e-commerce platform. But also install and manage the instance of Prestashop on a NGINX server and develop printing and generation modules of UPC barcodes for centralized inventory management in the store physical as virtual.

Designed to complement BBM radio surveys, StatsRadio is a listening tracker for real-time radio that can generate reports revealing graphs on performance statistics listening and comparing all radio stations across the province of Quebec.

This application, requiring high performance, was designed in simple PHP with the PostgreSQL database renowned among other things for its speed and the very high number of entries possible.

As a means of payment by credit card for subscriptions, I integrated the API of Moneris eSelect Plus and a simple billing system.

I designed this platform to provide a thoughtful configuration file for fine tuning.

Biography of a self-taught developer

First jobs in IT

In 2009, I was looking for a job as computer technician (repair and sell computers), so I met from the owner of SOS Informatique. After my interview, he tells me he would have more work suitable as computer technician for my knowledge base, indeed, at the 2nd floor of his business there was a mini data center with about 4 rackmount. So I got the job, and my job at been cleaning up infected sites with to provide technical support to customers, migrate infrastructure to newer equipment etc.

In 2011 I see an ad on the internet: search developer web. I had an interview and from that day on I had my first job as a programmer: at Wakeup Media Group.

In 2012, I received a very interesting job offer from the company Libéo, I was hired after a test of about 50 questions, where did I work for 8 months and I participated on many large projects.

Self-employed worker for some years

In 2013 I migrate the infrastructure of Groupe Quebec Telecom on servers hosted at Bécancour, more economical and safe (to save several thousand monthly $ in electricity). Since that time, this company no longer needed my services (because now, everything rolls like clockwork).

At the end of 2014, I decided to found SOLIB Solutions Open Source because I had several visions in mind that I wanted to achieve.

These 3 years have been the most challenging of my life, where did I learn and achieve the most projects, in the most different trades.

Motivation and objectives

Innovation, Research and Development

David Côté-Tremblay

With emerging technologies including the power of computers that is x100 to 10 years, I believe that machine learning is an integral part of the future (which is now!).

Some years ago, I started to learn different machine algorithms learning, which I find extremely exciting: classification, detection, recognition, prediction, decision, etc.

I see the emergence of the Internet of Things as an excellent opportunity for invent and develop new products and services. The markets for which I have the most interest are the commercial and industrial.

I have a great interest in all that is statistics and data visualization, and the methods of reading the database to display this information with as little latency as possible.

Sports and Recreation

I'm not an atlete, far from it, but I like it running in the woods. immediately that I have an opportunity to ride a bike and a little free time, the choice is simple: I leave for the day.

Since I'm not a fan of winter sports, usually during this period I take advantage to deepen my knowledge further.

Like most humans, I like to eat, drink beer, but also cook.
