    Work

    Currently I am working at Amazon.com as a Senior SDE III. I am in the retail/forecasting group, where we write applications for handling exception cases in purchase orders, forecasting and adhoc reporting. We use primarily J2EE, AJAX, Oracle, Spring/Hibernate on Linux based environment.

    Past Projects

    I have over sixteen years of experience and most of that have been primarily in web development that include:

    I generally distinguish developers into following categories:

    So, I consider myself hacker, generalist and tool builder. Even after doing programming for over 20 years (16+ years professionally), I still love programming and will continue doing it for the rest of my life. I started programming back in 80s with Basic on Atari, I then moved to C, on old x8080 machines, I also did COBOL, Assembler and CICS on Mainframe; FORTRAN on VMS, and C/C++ on SunOs (later became Solaris), IRIX (SGI), AIX. In my graduate school days, I did kernel tweaking on Minix, wrote ICON compilers and became interested in distributed computing. I became interestd in Java back in '95 and built a lot of large scale systems that used Java, CORBA, J2EE and JINI. These days my interests include Erlang, Haskell, Ruby/Rails, Python/Django, Scala, OCaml, Lisp/Scheme, Factor/Forth, Agile Methodologeis, JINI, JXTA, J2ME, AOP, SOA, Concurrent, Parallel and Distributed computing.
