We are hiring. Real-time 3D on non-real-time OS. C99. Almost no C++.

I was working on fun projects at Facebook/Meta Reality Labs on a range of Oculus products:Native XROS (fuchsia/Zircon descendant) - reimplemented WiFi Supplicant for use new async runtime, fixing data racing and deadlocks in the code.Reimplemented IMU sensors device idle detection to minimize inactive battery drain in all Oculus product line.Implemented code for collection of battery telemetry and orchestrated large scale DE/DS experiments for power savings.

Short:I am implementing portable infrastructure for zSpace tracking solution for embedded and mobile devices in C (C99) and C++. Mostly *d++ = *s++. More seriously high performance, cpu cache locality aware, multicore image processing algorithms in C and system components in C, C++, Java (Android) for both posix and Windows on Intel and ARM processors. Direct interfaces with USB camera devices and other hardware. Zero memory pressure debugging visualization UI.TLDR:My team and I are responsible for multiple IR cameras head and stylus tracking,stylus and screen angle IMU data-stream processing and integration, poses triangulation, and delivery of 3D data toend-user applications via C API.User facing applications are usually written using Unity 3D, OpenGL/DDX and other GL frameworks.System software also supports h/w manufacturing process, cameras calibration, overall components testing. * re-implemented ~~250,000~~ lines of C++ * implemented same functionality in ~30KLoC of pure C99 portable code * improved performance from 97% of system CPU utilization to less then 5% * actively maintained several github source code repositories * performed several thousands commits per year and many hundreds code reviews * developed new algorithms for high performance camera blobs detection * assisted porting those algorithms to FPGA * developed real time Android Java and Android Native C h/w debug applications * developed real time (less then 5 microseconds) logging * implemented native code for AWS S3 analytics data uploads/downloads * implemented posix complaint hardware tests * implemented some end user facing UI applications * resolved problems with Microsoft and Google related to Windows and Android codebases * contributed code to open source projects * contributed code to some open source projects

Architect and implement system software real time image processing pipeline for current and future zSpace magical products.

Architecture and implementation of a mobile platform (both server side and web browsers based clients) for broad range of smart-phones and legacy internet connected handheld handsets. Server side Java (jetty); smart JS; Facebook iLike (rip FB Connect); Maps; jQuery; WURFL; implementing UI for great customer experience. I have designed innovative architecture for mobile web social-casting platform that embraces smart-phone as well as feature-phone technologies and allow company to provide outstanding B2B service to variety of major partners.

I help (architecture as well as hands on coding) Dolby Advanced Research group to bring signal processing and image enhancement IP to Android mobile platforms.http://reviews.cnet.com/8301-13970_7-57388241-78/dolby-aims-for-richer-images-with-jpeg-hdr/

Working for YellowPages I was involved in several projects:in 2008 I have architected and implemented micro Swing for J2ME running on Blackberry smartphones and prototyped YPMobile application on that platform.in 2009 implemented YPMobile from scratch for new Android platform. I was responsible for general architecture of the application, infrastructure, asynchronous data retrieval engine, implementation of Virtual Earth map solution inside the application, HTTP request/response caching and main UI views. I have steered project away from XML based inflated layouts toward dynamic adaptable UI layout techniques.

Re-engineered and successfully shipped Clickstart Download Manager providing on-demand movie download experience to end users on Windows platform.

Designed implemented and successfully released original version of BookSmart application for Windows and Macintosh platforms.Lead a team of 3 software developers and 2 test engineers.Implemented a lot of UI code in Java.

Performance/security improvements for Google Desktop Search.

I designed and implemented debugger subsystem for GDB and Wind River proprietary DFW (Debugger j-tag Framework) for Eclipse IDE.The debugger subsystem implemented in Java and runs on Windows and Linux desktops.

I developed very first version of BookMaker. The code was written from scratch in a very plain C++. No use of MFC or ATL. The code was pure Win32, GDI, User, Kernel with message driven architecture. I would estimate original version of 30,000 - 50,000 lines of code.I frequently was contacted by MyPublisher for bug fixes and future improvement of existing codebase.

I designed and implemented the stack of first iPod drivers for Windows.

Implemented NextEncoder - multi-stream, muti-processor video/audio industrial strength encoder. Next Venue has been lately acquired by iBeam Inc.

I was helping senior curator of Computer History Museum Doron Swade with some research on USSR history of computing in 199x and later in 200x.

Designed and implemented Tornado-2 view docking framework and GDB debugger integration similar to Microsoft Developer Studio UI.

I was hired by AXS later Digital Collections Inc (DCI); Digital Arts and Sciences and lately Gallery Systemshttp://www.gallerysystems.com/In a capacity of software engineer I've re-implemented from ground up ImageAXS and ImageAXS Pro applications for Win32 platform. Original application was implemented for Mac OS 7.0 using PWB and Windows 3.1 (16 bit) using Borland C++.Some versions of ImageAXS are still available from variety of sources in the internet:http://gallery.sjsu.edu/tutorials/present/imageaxs.htmlI spent 4 years maintaining and improving ImageAXS application and supporting user community.http://en.wikipedia.org/wiki/ImageAXS

I was lucky to be one of the originators and a major contributor of a very exciting project:http://en.wikipedia.org/wiki/Kronos_(computer)I designed and developed or took part in implementation of following parts of Kronos Project:original microassembler for kronos firmware implemented on PDP-11 using Oregon Pascal;microcode for variety of kronos firmware;Modula-2 compiler;"ex" text editor similar to "vi" and "Emacs";kernel of Excelsior OS (Unix-like);kernel image linker;file system;device drivers (disk, serial, network, video, keyboard, mouse, ...);system utilities (ls, cp, rm, mv, ps, sh, ...);tar/zip style of archiving programs;graphic interface libraries;print circuit board graphic editor;3D design and modeling system bCad;portable ANSI C compiler and runtime;

I've implemented earlier versions of portable Modula-2 to ANSI C cross-compiler and ported it to variety of early Unix platforms among which Sun Solaris, HPUX, IBM Aix.
