I worked here with DevX India team where we provide build infrastructure for multiple operating systems. Cisco has various distributed operating system on which a router runs and dumps useful data at runtime. I have worked here to integrate the CTC++ compiler to multiple operating system build infrastructures where we capture build artifacts into MySQL database. Build compilations is done using CTC++ compiler. We have our own component in a build infrastructures which includes certain C and C++ files out of which shared library is created which is used in the linker commands for runtime linking. In addition to the compilation and linking phase, I wrote pre-build-stage script and integrated a postprocess script to insert relevant build data into database which can be used to get code coverage using report generation scripts. I have also worked for Cisco project named FireX which is completely developed in python with multiple microservices used to automate various OS build structure with a vast variety of options. I have also developed console based, safe and intelligent, MySQL application which is used by the end users for manual database changes and has also been integrated to various OS build infrastructures.
