Working on the team that brought you Adobe Fresco!Features: Drawing Overlay Infrastructure, Bounding Box Drawing and Transformations,Lock Transparency, Snapline, Pixel and Vector Fill, and other features yet to be released. https://www.adobe.com/products/fresco.html

Worked on enhancement and maintenance of Signal Image processing components for Ultrasound Systems.Worked on feasibility and transfer of research ideas into Ultrasound Systems. Implemented MicroFlow Imaging, a newly released imaging mode that overcomes issues with traditional methods for detecting slow and weak blood flow in small vessels.

Implemented new selection panes in Excel and PowerPoint that allowed users to keep track of worksheet and slideshow objects, and rearrange their placement and order.

Designed and implemented lighting automated tests for the platform rendering engine. Resolved lighting issues in the rendering pipeline. Participated on the investigation of performance issues. Created C++/CX D3D11 samples to exercise the HoloLens APIs. Designed and implemented a mesh processing tool to identify flat regions on 3D meshes:(1) Implemented a reader for meshes files in .ply format; (2) Created of a D3D11 desktop application to visualize meshes; (3) Implemented mesh data structures (half-edge); (4) Implemented mesh smoothing algorithms via Diffusion (Uniform, Taubin) and Curvature Flow (Cotangent); (5) Implemented data structures (octree) to accelerate geometric queries; (6) Implemented collision detection algorithms (based on Separation Axis Theorem).

Designed and implemented test automation for DirectComposition (Windows 8component that enabled high-performance bitmap composition with transforms, effects, and animations).Implemented several samples (some of them publicly available - see link below) to exercise the DirectComposition API and demonstrate its capabilities.

Implemented test automation for the DeepZoom feature in Silverlight. Designed and implemented framework to create Seadragon-based applications using Lua. Designed and implemented framework to create a mesh-based representation for images (via Delaunay triangulation). Designed and implemented framework to detect stutters in animations (via Differential Geometry operators defined on volumes) .

Designed and implemented Impress, an iPhone application that allowed users to manually create painting renditions of their images.

Designed and implemented several features (lighting, material, transform, geometry, etc) of the Handle Graphics component.

Designed and implemented test automation for internal APIs, UI and Extensibility framework of the Portable Media Center (hard drive-based portable media player platform developed by Microsoft).

Designed and implementated UI controls and calendar replication components for the MSN Calendar Client team. Designed and implemented UI controls and editing components for the MSN E-Mail Client team.
