This is Jothi kumar panchatcharam currently working a senior software developer in SITA with more than 8 years of programming/designing in Atlanta, GA . I am in the preliminary stages of applying for Canadian PR through Express Entry Federal skilled program and I am on the lookout for Job opportunities in Programming/Technical Consulting/Architecting as I believe landing a right job might take quite a bit of time.
On the business front, all my experience has been with developing and architecting complex application in the Airlines/GDS industry with very in depth knowledge on Reservation, Ticketing, DCS, Revenue management, Messaging protocols , EDIFACT and  external partner coordination.
On the language front. I used IBM mainframe assembler, Low level C, C++ , Java , Perl etc and still on the hunt to learn more programming languages currently ( JavaScript and python) . If I could master a programming language, I could master any programming language . All I would need is opportunity and little bit of time while I work on the job. Background in Electronics engineering have led me to use Verilog, VHDL, MATLAB and microprocessor assembly as well.
I am currently responsible for developing application software and supporting and maintaining applications across 40 physical servers with 80 app environments in a big enterprise organization with all the servers in Linux RHEL and some in Solaris unix. Have good experience on both Monolithic architecture and Microservice architecture.
On the database front, have good knowledge on SQL even though did not have the chance to use it extensively. Currently trying to learn NoSQL database such as Cassandra and MongoDB.
Since the applications we own and manages are one of a kind, we do get involved in a lot of operational activities and currently on the verge of using Jenkins to accommodate the ever growing number of environments we manage. We are the very few ones who see and know and big picture in the distributed environment and understand the message flow across different components and developed the capability to identify the component/point of failures using different tools/methodologies.
We have developed a custom monitoring server with LAMP architecture purely for our monitoring/operational needs .
 If you feel , I am a potential candidate please contact me +17705487270 or email me @ for more clarifications.
