Software developer since around 1972, starting with the HP programmable calculator HP97. Yeah. I'm an old guy. My first real computer was a TRS-80 Model I.
Did 10 years at Boeing as software developer. MVS 370 mainframes, VM, 3270, IMS, etc. Picked up 'C' and never went back. Linux, Solaris, HP/UX, Oracle, MySQL, DB2, SQL Server. Various Network products. SNA, TCP/IP, and protocols (SNMP, SMTP, POP3, HTTP, FTP, etc.)
I've got an Android version of HP67 out on the Android market. Still have working TRS-80 Model III, C64 and a few other old beasts. Love old computers.
Constantly learning new systems, frameworks and languages. Currently working in trading and financial service industry as a senior developer / development manager.
