I led a team of multidisciplinary developers (frontend, backend, devops) that built a platform that powers dozens of car dealership websites and web applications. I laid the foundations of the infrastructure, software platform and production tools. These resulted in a maintainable and customizable frontend framework, a high performance backend, and automated and reliable deployments.As a team, we established quality-driven culture and agile practices: we do code reviews, daily standup meetings, continuous integration and short sprints. As our team grew, I always made sure that everyone was learning and improving.My technical achievements include:- A semi-hierarchical caching system covering different data sources that can be partially invalidated.- A media pipeline: auto-crop, asynchronous operations, multi-upload, CDN.- Reliable and distributed deployment system.- Configuration and maintenance of reliable infrastructure: web and app servers, cache servers, databases, etc.Technologies: Python, Django, PostgreSQL, Memcached, Puppet, Linux, Redis, Media Processing Pipeline, Cloud ComputingAreas of expertise: High Performance Application Building, Team management, Customizable Framework Building

I conducted a qualitative study by recruiting and interviewing high-profile contributors from eight large and popular open source projects to better understand the challenges in creating and maintaining developer learning resources such as documentation and mailing lists.I created an analytic system that automatically (1) parses and models developer learning resources, (2) links these resources to a system's codebase, and (3) recommends improvements on the learning resources. One of the major technical challenges was to automatically process documents in natural language.Technologies: Python, Java, Django, Eclipse Platform, Memcached, PostgreSQL

I created and taught a 4-credit course on Software Architecture to a class of 20 undergraduate and graduate students. I used active learning activities to engage students and to make them responsible for their own learning.For their course project, I asked the students to pick open source projects in a specific domain and compare their architecture. For example, a team of students compared nginx, apache and lighttpd.Topics covered by the course: Components & Connectors, Architectural Views, Architectural Styles, Reference Architecture, Extensibility Patterns, Performance Patterns, NoSQL, Cloud ComputingCourse Website: http://www.cs.mcgill.ca/~bdagen/comp529/index.html

I conducted a qualitative study on experienced developers joining 18 ongoing software development projects at IBM. The study approached the problem from a unique perspective, that of a newcomer relying on orientation aids and encountering obstacles while exploring a project landscape.I also worked on a concern-oriented approach to software documentation to make the creation and maintenance of developer documentation more efficient. Developers could drag and drop software artifacts in a tutorial editor and the editor inferred the documentation steps to create.Technologies: Java, Eclipse, Qualitative Methods

I created a technique that used a program slicer to extract functional aspects in legacy Java programs. The technique was packaged as an Eclipse plug-in that included a Java program slicer. Users of the plug-in could select a few important classes in a legacy Java program and the plug-in identified important classes and methods that were related to these classes.Technologies: Java, Eclipse, Soot (Static Analysis Platform), Indus (Program Slicer)

I prepared exercises and taught for the following courses:- Data structures and algorithms (C++)- Programming I (Java)- Programming II (Java)I received twice a special mention because I received the highest course evaluation from the students.

I redesigned the architecture of the flagship mobile application in SAP's Montreal lab. The project was challenging because new features were being implemented at the same time so I had to constantly communicate with the team and coordinate the evolution of the features and the architecture (2005).I designed the architecture of the first CRM online mobile application at SAP. The product became a reference architecture for similar mobile applications (2004).Technologies: Java, J2EE, SAP NetWeaver

I advised the purchasing and accounting departments on the transition to a new ERP system (Oracle).The transition was a success despite the strong resistance to change: I trained key personnel and involved them in the improvement of the organization's business processes.
