Total des années d'expérience :17 years, 8 Mois
Investigating technologies such as graph databases and distributed computing engines for large-scale data processing and analysis: Neo4J, Apache Spark, etc...
Researching, implementing and comparing algorithms for future projects.
Took part in developing a panorama stitching and viewing application on both web (browser based) and mobile platforms.
Image registration and blending is based on an in-house algorithm.
Mobile part is an iOS app (DMD Panorama, > 6.6M downloads) written in ObjectiveC, C, C++ and GLSL. It can produce 40 mega pixels, 360o panoramas (Apple's panorama mode is limited to ~25MP and ~230o). The engine (the algorithm’s wrapper) is multi-threaded and utilizes the GPU and iOS performance techniques which enabled us to achieve extreme speeds without sacrificing quality.
The app also features a public galley, user profile, panorama uploads to our servers for sharing and other social features.
The engine is also packaged as a library and licensed to other companies (360Cities.net, cycloramic.com, etc).
Web based app is an SWF object written in ActionScript 3 for the UI, Adobe Pixel Bender, C and C++ for the core engine.
Server side uses CentOS, Apache, MySQL & PHP stack to offer backend support for the mobile and web apps.
Developed project's API and UX, coordinated between UI and front-end development teams
Developed the server communication socket in ActionScript 3 and a JavaScript API that's being used in their real-time analytics website (woopra.com/live).
Linux server installation and maintenance, Windows clients support. Hardware maintenance.
Developed a Business and Contacts Management software for the sales and marketing department.
Developed a CAVE (Cave Automatic Virtual Environment) system with stereoscopic 3D imaging (anaglyph 3D mode) which used 3 computers and 6 projectors to project a virtual world on 3 walls.
The software reads a scene description file which contains objects, timed actions and movement paths then renders the scene on each computer from a different point of view (master-slave). A user located in the middle of the room can navigate through the scene.
The software is written in C++ and uses Irrlicht 3D engine for object loading and OpenGL abstraction. We modified the rendering engine of Irrlicht to handle stereoscopy. The 3 computers' rendering was synchronized using UDP sockets. OpenAL was used for 3D sound.
Developed an interactive virtual reality table display (a small demo http://youtu.be/HXLQBOeiZng) that used 2 projectors for stereoscopy and a webcam to detect user interaction. We used PhysX Engine for physics and a modified version of Irrlicht for rendering. The user can cause objects to fly off the table by using a lighter.
Developed an online multiplayer board game (wineentertainment.com) using ActionScript 3, PHP and MySQL. The game is turn based and features a chat system for each room.
Developed a website for an online magazine (executive-magazine.com). Note that they have changed it.
Requirement gathering and draft design for database and application.
On site hardware and software support.
Hardware and software troubleshooting.
Computer assembly.
