Languages C,Objective-C,C++,JavaOperating Systems Linux,iOS-Apple, IOS-Cisco, MS-WindowsTechnologies / Practices Layered approach to object hierarchy design, isolating behaviors and dependencies, with clean calling interfaces. Animation work includes writing 2D animation engine in Java. Using Objective-C on iOS, have written a good deal of animation code using both Core Animation with CALayer’s and UIView based animations. Some CALayer animations incorporate monitoring of the presentation layer for timing the coordination among multiple animations. Networking projects include multicast, udp unicast protocols, state restoration and failover. Also wrote a MADCAP server and basic HTTP server.ProjectsApp for Music Notation Touch input and editing of music chords / notes on iPad. Offer piano and guitar notation without music theory prerequisite. Challenges include turning music theory into code, offer intuitive interface flow, clean separation of Core Data data model from rendering layers. Incorporated state restoration that is called upon after backgrounding of App. Also make use ofmultitasking for maintaining responsive, context aware user interface.Mid Range Router Guaranteed delivery of router configuration commands to distributed processor boards within router, even during router resets. Software upgrading while router is running, no loss of traffic. State exchange for redundancy and failover support.Handheld Device Synchronization Protocol and SDK Design Define custom protocol for handheld device communication with PC. Support packet assembly, disassembly with retry timeout logic. SDK design for 3rd party developers, offering communication and synchronization from PC to device hiding underlying protocol mechanics.
