Work Experience

• Senior Software Engineer @ Uloop, Mountain View, CA : (2008 Feb - Present)
  Uloop aspires to be the ultimate hub for students - classifieds (books, jobs, housing) , course reviews and discussion forums - all in a walled-garden for each university.
  As as senior engineer I develop site features, monitor and maintain the site, build admin tools and reports. The development environment is LAMP with Qcodo framework.
  • developed and launched major site features (Discussion Forums and Course Reviews). Focus is on clean design, usability and interaction(ajax) (screenshots)
  • Implemented a site-wide Email system. It handles creating and sending targetted emails to users and effectively distributes large amounts of emails without tripping spam triggers
  • Performance tuning : tweaking cron-scripts, caching system for reports
• Software Engineer @ IBM, Burlingame, CA : (2002 Feb - 2008)
  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.

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.

  • advisor and consultant for startups and entrepreneurs

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.
