I'm a developer who enjoys learning the math behind a domain — how its careful application solves complex problems elegantly.  An open-source contributor passionate about knowledge sharing. I live in Emacs and love the command-line.

Microsoft ~ Senior Software Design Engineer
Conceptualized and implemented the texturing subsystem on a roadmap project implementing the OpenGL ES specification using Direct3D.
PDF Engine
Authored Annotations component of the PDF rendering engine used by the Edge browser and the store app Reader.  Additionally took care of print and rendering subsystem involving transparency (compositing and blending) and shading patterns.
Edge - Build Systems
Own sync and build of entire Edge codebase with its 200+ third-party dependencies on multiple platforms over Azure Pipelines at scale.
Edge (macOS)
Design and implement macOS-specific browser features including tab dial and media controller experience for MacBook Pro Touch Bar.
Havok / Microsoft ~ Developer Relations Engineer II
Worked with clients to integrate Havok Physics, AI and Animation solutions with their game code. Provided solutions to game play issues; advised on approaches to physics engine integration depending on the game world.
Account Manager: Call of Duty: Modern Warfare 2019 (Infinity Ward), Assassin's Creed Odyssey (Ubisoft Quebec)
Electronic Arts Mobile ~ Software Engineer I
2D Game Engine
Authored a 2D game engine and associated tools for artists to work on sprites and resource packing.  The engine abstracted differences amongst WindowsMobile devices and exposed a common feature set for game teams to work on.  Its basic features like image drawing to advanced ones like animation and blending were implemented from scratch.  It sported effects like on-the-fly grey scaling and parallax scrolling.  Ported J2ME (Java) game code of Jewel Quest III and Sims 2 Castaway to WindowsMobile (C++) using said engine.
Aricent ~ Software Engineer
DirectShow Filters
Authored source filters for A/V codecs like A-Law, μ-Law, H.264 and for progressive downloading of (YouTube) videos on Windows Media Player.
Field of Vision System
An optimized field of view and line of sight system for visibility queries in strategy games (live demo); minimizes intersection tests to use in a game with multiple AI agents needing FoV every frame. My design with illustrations and the geometry involved is documented in excruciating detail. Sneak out! is a game, playable in your browser, written in 3 days using this.
Navmesh Path Finding
An optimized navigation mesh based path finding system for strategy games (live demo)
3D Workouts
Multiple mid-sized projects to understand fundamental 3D math and graphics concepts from ground up using no high-level libraries.  Right from primitives to collision detection to spatial data structures to frustum culling everything was implemented manually from scratch.  Highlights:
Spirit of C++
Extensive C++ tutorial for intermediate programmers (live demo). I've trained multiple teams in Microsoft with this in my C++ bootstrap workshops. The larger C++ community received it well too.
2D Transforms 101
A featured interactive tutorial on geometric transformations for programmers favouring intuition over mathematical rigour; concepts explained are illustrated with animation.  In addition to elementary transforms on points, it also treats coordinate system and hierarchical transforms; shows mappings from active and passive viewpoints.  It can be viewed on a browser and in any form factor, as it only uses HTML5 and vector graphics.
Handy offline thesaurus originally written on GNU/Linux (most distributions' repositories host it), using WordNet as its database, with distinct features like global shortcut key look-up, passive desktop notification and wild-card search.  It was later ported to Windows. It garnered many positive reviews and recommendations from users.
