My projects

• tripyogi.com
  Co-founder of TripYogi - a meta travel site for Indian domestic air travel. Site featured route calculation with multiple airlines, discount fare comparison and trip planning with trains and planes.
  [LAMP stack (php), spidering airline websites, route calculation, MS Live maps]
• GPS way point viewer
  Developed this mash-up to help me and other photographers who use GPS waypoints to mark locations for photography. See waypoints in a Google map and search the waypoints for a keyword (sunset) within a area defined by the map
  [Javascript - dojo, Google map APIs, GPX file format, geo-coding ]
• Holiday Lights Googlemap mash-up
  Displays nice holiday decorations around bay area in an Google map along with photos
  [LAMP stack, Google Map API, javascript, photos ]
• When It Happened
  Social experiment to find out where people were and what were they doing when monumental news stories broke (e.g. space shuttle Challenger incident)
  [wordpress blogging software, ratings, spam comment control]
• 304 card game
  A Multi player, network aware card game in Java (in beta stage)
  [Java server with chat + user authentication + game logic, Java NIO and threading for scalable connections, firewall friendly networking, pluggable client architecture for human clients and AI robot clients, cross platform GUI client in Eclipse JFace]
• ProjTimer
  Measures time spent on various tasks on a working day with minimal user intervention. Useful for status reports and consultants billing by hour A small Java application with intuitive Swing GUI, fast and responsive, and easy to use. The GUI and core code are re-used in another open source project SimpleTracker
  [Java swing]
• Facebook Apps exploring Facebook APIs
  [RFacebook rails plugin]
• exploring location aware searches with GPS + 'yellow pages data'
• Technical articles and HOWTOs
• Startup involvement
  
  • QodeBook.com : A micro mobile payment startup.
    Setup software development infrastructure (svn repository, daily builds and backups). Wrote majority of payment processing server in Java (scalable network layer with Java NIO, data base connection pools). Collaborated with developers over different time zones
  • building facebook integration for a stealth startup
    [Facebook API, Symfony]
  • advisor and consultant for startups and entrepreneurs

Work Experience

• Software Engineer @ IBM, Burlingame, CA : (2002 Feb - Present)
  Former company Crossworlds was acquired by IBM
  • working on RFID middleware. Designed and developed software in Java according to EPCIS spec. Built automated testing framework and coverage tools. Customer deployments and support
  • Added Web Services support for business work flow design tools, making it easier to discover and invoke web services ( patent granted [# 20060271537])

  • Eclipse tooling development (JFace, GEF, EMF). Worked on a graphical editor (that is part of IBM developer suite) that allowed to easily expose an operation as web service - screenshot
• Software Engineer @ Crossworlds, Burlingame, CA : (1999 July - 2002 Feb)
  Crossworlds did Application Integration Middlware.
  • Responsible for porting the product to Solaris platform (primary platform was NT). Code is 80% Java, 20% C++. Made existing C++ code portable with MSVC++ and Sun CC compilers (JNI layer / building dynamic libraries). Defined a standard to write portable C++ code. Implemented a build system on Solaris and administered Solaris SPARC boxes. Found platform specific JVM quirks (thread scheduling, DLL loading) and wrote work-arounds.
  • worked on performance tuning of Crossworlds system (Java performance). Created and analyzed prototypes for improved performance. Used profiling tools - PerfMon (windows NT) Optimizeit, and JProbe - to analyze program behavior / bottlenecks / thread operations. Compared performance of different JVM implementations (Sun / IBM and JIT compilers). Studied scalability (system and JVM) across multi-processor (SMP) systems. Benchmarked Crossworlds releases. Implemented performance tools to measure Crossworlds System performance
  • designed and developed integration components in Java
  • Introduced many coding standards and practices into the team (IDEs, Makefile templates, version control strategy, code reviews)
• Engineer @ Open Software Associates , Melbourne, Australia : (1999 Jan - 1999 April)
  OSA ships a cross-platform GUI(C++) and a program deployment tool. Handled Mac OS release. Wrote automated test cases
• Internship @ Indian Institute of Science (IISc) Bangalore, India. : (1997 Nov - 1998 Feb)
  IISc is a premier post graduate research university in India. I worked as an intern part of IBM's global university program. Wrote a message passing toolkit based on IBM MPL (Message Passing Library) to make it easier for parallelizing computationally intensive programs on IBM SP2 cluster. OS : AIX, Language : C++
• Intern @ CSIRO Melbourne, Australia : (1996 Nov - 1997 Nov)
  CSIRO is a government research organization in Australia. I worked in the Melbourne branch as an intern during summer vacation and also part time during my final year at university. Developed a Java Applet for an online 'remote diagnosis tool'. Developed utilities like text parsers, Swing GUI controls, graph layout algorithms to aid programmers working on a large scale projects.

University Education

• honors with many Dean's List awards
• Final Year Engineering project :
  Developed a system that allowed a dish antenna to be controlled over the Web. A PC running RT-Linux controlled the motors and actuators of the dish. Another Linux machine served as the firewall and web gateway. It ran a custom Java web server that took input from the Java applet and sent commands to Dish controller. A Java applet on client side had controls for moving the antenna and displayed real time status. Client UI also had high level commands to track satellites or celestial bodies. (RT-Linux, C, low level hardware drivers, satellite motion algorithms and orbit data from NASA, Linux, a custom built Java Web sever, Java applet [screen shot 1, screen shot 2])
  I was part of a 3 person team that worked on this complex project for a year. It was chosen as as one of the top projects of the year. Future Engineering teams built projects on top of our work.
