About
SigmaPi Design is a virtual company with one virtual employee and
one real person.
My name is Sinisa Petric and Greek letters SigmaPi stands for my initials.
Currently I'm full time employee of FINA agency Croatia and I work on digital imaging
programs in my free time and mostly as a hobby (besides guitar and Aikido).
Here is my CV:
I was born on March 6, 1959 Split, Croatia.
I've graduated theoretical physics in 1983 (Zagreb University)
on mathematical modeling of nuclear structures.
I worked on UNIVAC machine using FORTRAN and PASCAL as
languages for numerical computation.
Here is a list of my jobs:
- "Faculty of Electrical Engineering", Split - Scientific assistant in Solar Energy Laboratory.
Programs for solar energy simulation, simulations on nuclear power plants gas dispersion, theory of graphs,
programming on IBM370 machine under MVS/TSO operating system.
- "ZERC", city computer center, systems programmer on IBM370 mainframe machines
under VM/CMS and VSE operating systems. Programming mostly in Assembler/370,
FORTRAN, PASCAL and REXX language.
- "Pomorska Banka", systems programmer, IBM370 machines, mostly assembler/370 and REXX programming,
PC/DOS, Microsoft/C and CA/Clipper.
- "ITEM" company, software servicing of mainframe computers, application programmer
and data base designer on RISC/600 machines running under IBM/AIX op.sys. with ORACLE relational base.
- "M-SOFTWARE" company, ORACLE forms, UNIX/C, CodeBase and CA/Clipper, SCO/UNIX, OS/2 op.sys.
- "FINA" - financial agency, systems and application programmer, programming in CA/Clipper for PC/DOS using Netware SQL on Netware 4.11,
Borland C++ Builder using DB/2 under Windows NT Server and MVS (IBM390) as a server side.
Still employed in "FINA" and working with Java/J2EE on IBM Z9 mainframe using
"IBM Rational Software Architecture" as a development tool.
And yes, I'm not a fan of Java language...and it sucks...but...
Here is the partial list of programs I have written as author or coauthor:
- CMS backup (two men team) , assembler/370, REXX
- VSAM editor , assembler/370
- VM/DRAW , assembler/370, REXX
- Multi VSAM engine , assembler/370, REXX
- Full screen module for FORTRAN/VS, assembler 370
- Integrated financial system for medium and big companies (6 men team)
, ORACLE, ORACLE forms 4, Pro C, CodeBase
- Payroll program , CA/Clipper, DBF
- UNIX full screen editor , UNIX C
- Financial transactions archive, CA/Clipper, Netware SQL (40,000,000 records squeezed in 14GB)
- Tracking companies with blocked conto (three men team), Borland C++ Builder, DB/2
- Image processing programs, BCB (under development - always)
- Consulting on medical image processing projects, chinesiology software and license plate recognition systems.
Here is the list of programming languages, tools and DBs I've worked with:
-
assembler IBM/370, REXX, Fortran, Pascal, C/C++, Java, Reduce, List, Python, HTML/CSS,
Borland C++ Builder, Microsoft Studio, IBM/Websphere, DB/2, Microsoft SQL, ORACLE, etc...
