OPENING REMARKS:
I've tried putting together all my productive activities in as-it-is
style. This gives employers greater ease to mix-n-match my skills with
their requirements in an optimized manner. I am looking forward to
discuss the assignments with prospective employers who require a set of
my key skills.
Talking of my preferences, I would prefer -

PROJECT DETAIL:
Feb 2004 - Dec 2005: I am
working on benchmarking Blue
Gene , that is
#1 supercomputer at present, and optimizing its
performance. The benchmarking includes benchmarks like SPEC, HPCC,
and
MM5. SPEC is a benchmark having group of 26 common
applications like
gcc, gzip, etc from range of variety of domains to indicate single cpu
power. HPCC is a group of programs to study parallel algorithms that
rely not only on cpu power but communication between them as well.
Matrix transpose, multiplication of HUGE matrices that can not be
allocated to single cpu memory are such examples. MM5
is part of weather forecasting system that primarily implements some
sort of FEM. Optimization is done primarily in three steps -
Jan 2003 - Dec 2003: After
years of nonstop work, practically without breaks, year 2003 was a year
of rejuvenation for me. However there are two small exploratory
projects which are worth mentioning that I undertook. The first one
was related to microcontroller programming while the other was related
to 3D modelling.
Equipped with multimeter and soldering
iron, I assembled 8051 programmer kit hardware. The programmer could be
used to program Atmel AT89C51 microcontroller using parallel port of
the PC. The assembly code (.ASM) of test program to blink LED was
converted to HEX (.HEX) representation using Boreland TASM assembler.
This was then transferred to 89C51 using software component of the
programmer kit on the PC through parallel port. Also I assembled
development & debugging platfrom kit which itself uses 89C51
microcontroller and has a keyboard, LED display, RS232 interface and
interfaces to various IO ports. The monitor (driver) program was
assembled on the PC using tasm and a microcontroller was programmed
using abovementioned programmer kit. This programmed microcontroller
was then put into devlopment kit. This kit, can be used to enter the
assembled HEX code, view and modify internal registers and memory
locations and run a particular piece of code. Also the entered data can
be stored persistently between two different sessions. ( See
Electronics For You Jan 2003, Feb 2003)
During second half of 2003 I explored
various 3D-modelling & animation and video editing techinques using
Blender, povray, Yafay, VirtualDub, Broadcast2000 and Cinelerra. An
animation sample was dubbed with music and vcd was made using Blender,
mjpeg tools, vcdimager, vcdgear on Linux and was tested successfully on
VCD player/ TV combination. Similarily a 15 sec animated birthday
greeting was created. I have also tried to record video from VHS
cassettes and convert these to VCD format, using PixelView card (Bt878
chipset) NuppleVideo, exportvideo and mjpeg tools. The quality of
recording was fine but after multiplexing video and audio streams into
mpg these were out of synch somewhere in between.
Oct 2000 - Dec 2002:
Worked
as Project Manager for CallConnect 4.x with team size varying between
5-9 people. CallConnect is Siemens Information Systems Ltd's product to
implement Call Centers. The Product suite consists of a server
application
along with C-API, ActiveX components, a client template in VB, an
outbound
campaign manager server, campaign generator and softphone, message
player
and web based administartion and supervision. Besides these I was also
administering GNATS bug tracking tool for various projects within the
company.
I've developed web interface to administer Gnats databases using perl
cgi
scripts which is accessed through Apache web server on Sun Solaris.
Oct 1999 - Sep 2000:
Worked
as Technical Lead for CallConnect 3.0 and 4.0. During this period I was
involved with developing protocol for synchronized voice and data
transfer
between Telemaster IVR and CallConnect system. It was during this time
that we acquired TADIRAN and HICOM PBXs and ported our code to work
with
these PBXs. During this period we also incorporated CTConnect's API
into
our product and designed/implemented C-API for our server.
Feb 1999 - Sep 1999:
Worked
as a team member for CallConnect 3.0. Here I implemented synchronized
voice and data transfer during transfer and conference operations.
Jul 1997 - Feb 1999:
Worked
as freelance software developer for HACE India Ltd. I developed a few
products
collectively called as Virtual Instruments. These systems were Data
Acquisition
Devices (DAD) which had analog to digital converters on serial port.
All
of these shared same hardware and different products were packaged
using
different rules of data transformation, storing and display. A few of
these were named as Data Logger, X-Y recorder, Weather Station, Single
and Dual Met. Parameter Recorder. I developed these VIs in C++ using
Boreland's
C++ 4.0/5.0 IDE for Windows 9x using Windows SDK. The work involved was
based on already existing Windows 3.1 codebase in SDK. The data
acquired
were transformed using some configurable formulas, stored in
proprietary
formats as flat files and displayed in various modes- text, bar, dial,
graph. All the graphics was developed and encapsulated as library to be
used.
Jul 1995 - Jul 1997:
Worked
as research assistant as a part of Ph.D. Program at IIT Delhi. The
project,
I worked on, was related to non-equilibrium thermodynamics applied to
biological
systems. It was computational/theoretical project and involved
mathematical
modeling and simulations. I used Turbo Pascal 7.0 and Turbo C++ 1.0 to
implement some models. As part of assistantship, I worked on simulation
studies in Packed Bed Reactors, which was realized using C++/BC++2.0.
During this time I also attended one semester course on Mathematical
Foundations
of Computer Science and learnt about Turing machines, computability
etc.
Jun 1994 - Jul 1995:
Worked
as scientist at CADD (Computer Aided Drug Design) Unit, Torrent
Research
Center Ahmedabad. I worked on identifying Angiotensin II antagonists.
Angiotensin II is a fragment of protein with eight amino acids, which
is
known to increase blood pressure in humane body. An antagonist is a
substance
having similar properties as Angiotensin II but its effect on BP is
neutral.
The work required energy minimization study of structures in dynamic
simulations.
Cerius II drug discovery Workbench was the main tool along with QUANTA
and
CHARMM on HP 9000 systems. I often wrote and used shell scripts and C
programs
for data transformation to desired format generated by abovementioned
tools.
Pre 1994: I learnt programming
in the
very first year I entered IIT Delhi in 1989. It was
PASCAL/TurboPascal5.0/DOS4.0/286
system. I did a course on Data structures and learnt C during second
year.
Towards final years, I have to learn FORTRAN to use a simulation
package
library written in FORTRAN. Final year project was modeling and
simulation
of charge flow within an ion channel. I used PASCAL to implement this
project.

INFORMATION:
About CallConnect
Product
Suite: The CallConnect server is a multi threaded application
written
in C++ for Windows NT4.0 using MSVC 5.0/6.0. It receives telephony
events
using Novell's TSAPI or Dialogic's CTConnect API. Based on these
events,
it manages agent/call states and statistics and can log these to MS
Access
97, Oracle 8.0 or MS SQL 7.0 using ODBC. It uses UDP/IP sockets to
communicate
to agent desktop applications. Synchronized screen pop is delivered to
the agent desktop during transfer from one agent to another agent and
conference with another agent. A protocol is been devised and
implemented
for synchronized voice/data transfer to/from SISL's Telemaster IVR.
The web UI has been developed in JAVA Applet/servlet while C-API
has been
enhanced to provide statistical information as well. Message player
component
added which uses Dialogic's analog voice cards to enable callceter
supervisor
to define voice messages to be played to customer when he waits in the
queue.
There is whole range of basic and advance routing schemes and priority
queuing
which were added during this period. List of supported features can be
viewed
here
We were working on incorporation of Call Blending, multimedia
support and multi-site support in the CallConnect 4.X when I left the
project.
About
CallConnect
Product Deployments: We have deployed our product first time at
Grameen Phone Dhaka (Bangladesh) in Sep 2001. During my
association
with the project, we had deployed it on 5 more sites. ( BSNL Karnal,
BSNL
Gurgaon, BSNL Hyderabad, BTNL Bhopal, SBS Chilworth (UK)). My group
developed
agent screens and customized Reports for Grameen Phone, BTNL Bhopal and
SBS Chilworth implementations.
