• Enablement for AMD architectures. Performance improvement and release handling.

Feb 2007 – Sep 2010 · 3 yrs 7 mos

• Ported GCC (the GNU C Compiler framework) to a 32-bit MIPS like microprocessor.
• Explored GCC framework features as part of feasibility study for porting it to a VLIW DSP processor. Wrote the machine descriptions to handle pipelining with multi-ALU support and instruction bundling. Described the machine features for enabling auto vectorization
• Maintained the compiler developed for 32-bit MIPS like microprocessor. Identified defects and rectified them. Solicited requirements, gathered and analyzed them, checked their feasibility and implemented them.
• As part of leadership role, devised plans and strategies to meet deadlines. Collected metrics which could actuate future actions. Succeeded in building a sustainable team. Handled off campus and on campus recruitments devising key competencies aiding the selection process.

Dec 2004 – Jan 2007 · 2 yrs 1 mo

• Worked in the maintenance stage of a compiler developed for a 32-bit MIPS like microprocessor.
• Identified defects, reported them in the proprietary defect tracking system of the company. Solved defects by root cause analysis, prepared reports and checklists as preventive actions. Refined and refactored legacy code.
• Evaluated the compiler by testing it with industry standard test suites. Prepared test specifications, devised testing strategies, coded tests and evaluated the compiler with the written tests.
• Used quality assurance tools like static analyzer (PRQA -> QA·C) and explored possibilities of using SAL and PREfast in compiler source. Used NuMega quality enforcing tool Truecoverage for measuring the coverage percentage test written for the compiler source. Used NuMega Boundschecker to handle memory errors.

• Worked in the quality assurance of a compiler developed for a 8-bit RISC microcontroller.
• Devised test specifications wrote the tests that would check the defect fixes.
• Worked with the proprietary quality validation system of the company learning its niceties and amending its capabilities.
