DP Technology develops ESPRIT, a computer assisted machining (CAM) software used by the aerospace, defense, medical and watchmaking industries. It offers powerful programming features for any CNC machine tool. ESPRIT grosses $30 million per year and is used by Tesla, Citizen and Halliburton.Role: Software quality technical leader for a multi-continent team of 30 engineers located in USA, Italy and GermanyActions:• Kept a finger on the pulse of our flagship product ESPRIT to ensure high-quality software releases• Managed a team of 2 engineers in the US headquarters• Trained and mentored software engineering interns• Orchestrated the quality team's portfolio of priorities according to the stakeholders' and clients' expectations• Advised executives when to compromise on new development so more resources could be allocated for quality and testing• Slashed our organization's hardware costs by 60% by promoting machine virtualization and by improving load balancing of automatic replays• Supervised the build system, reducing turnover time by 15% and release failures by 50%• Increased code coverage to 80% in critical, previously untested areas (real-time simulation, geometric kernel, machining feature generator, document reader)• Reduced test redundancy by 90% by evangelizing targeted acceptance scenarios and reusable test templates• Helped increase the solution's stability by 50% by promoting stress-testing, performance and memory-profiling campaigns• Created a custom testing, validation and release deployment framework using the .NET platform and Windows automation (batch scripts, SysInternals library)• Coordinated the creation of an MVC intranet website to centralize quality metrics and provide live status of all ongoing builds and replays (using ASP.NET and C# Razor)• Helped maintain and improve the continuous integration system for developers

Role: C++ developer for ESPRITActions:• Developed a CAD document reader enabling users to load over 53% of the mainstream CAD data formats available on the market with 95% accuracy• Helped redesign the "selection by propagation" command on solid models, reducing programming time by up to 90% for 5-axis machining operations• Improved the solution's feature recognition to automatically extract CNC-relevant geometric patterns from complex 3D models (using the Parasolid kernel)• Designed 4 new machining strategy algorithms that reduced programming time for drilling operations by at least 50% (along axis, zig-zag, spiral/helical, shortest path)• Created 2 new machining features to solve problems specific to EDM technology (slug retention for die and punches, internal/external cornering)• Revamped, optimized and tested legacy code for better maintainability

Dassault Systemes develops an eclectic portfolio of 3D design enterprise software. Two of them are particularly famous: the user-friendly SolidWorks, and the professional-oriented CATIA.Role: C++ developer for CATIA and ENOVIAActions:• Participated in a taskforce created to reduce the bugs crippling the compatibility between CATIA (a 3D CAD solution) and ENOVIA (a PLM database), reducing the issue backlog by 80%• Redesigned CATIA's rapid tool motion algorithm and UI/UX from the ground up• Developed data models and user interfaces for CATIA's 5-axis machining library• Deployed software features in a multi-platform environment (UNIX and Windows) using TDD (test-driven development) principles• Covered untested areas with automated non-regression tests (unitary, integration and GUI)• Trained other teams on cross-platform and interoperability matters

Created a new software plug-in for the company's solution (ESPRIT) enabling users to easily draft complex involute gear profiles from simple technological inputs (number of teeth, pitch circle diameter, tooth addendum/dedendum, tooth thickness, face width).The involute tooth profile was approximated with tangent arcs using a high-precision algorithm to accommodate the geometrical limitations of CNC machines and G-code (only arcs and segments can be cut).This solution enabled end-users to cut spur gears from a flat stock billet using an electrical wire erosion machine, a CNC mill or a water abrasive jet machine.

Implemented a test suite for a mobile phone web browser ("N@vigate") in Schlumberger's now-defunct Smart Cards division. This entire business operation belongs to Gemalto since 2006.
