Programming Research Ltd.| Senior Software Developer | 3/2010 – 9/2018 |
- Quickly became a key member of an elite C++ team by building on previous C++ compiler implementation experience.
key technologies used: test-driven development
- Key developer responsible for extending the in-house C++ parser to support C++11/14/17 features: auto type specifier, decltype, scoped and strongly typed enums, inline namespaces, explicitly defaulted and deleted functions, explicit conversion functions, rvalue references, variadic templates, noexcept, alias templates, user-defined literals, inheriting constructors, range-based for loops, lamda expressions (including init captures and generic lambdas), uniform initialization syntax, variable templates, nullptr, unicode character types, constexpr. Ensuring quality of implementation by testing against the boost library and cross-checking test-cases with gcc, clang and Visual C++.
key technologies used: latest C++ standard working draft together with the C++ core working group issues list
- Static code analysis for C++: Implementing new static analysis checks, ongoing maintenance and bug-fixing.
- Contributed to the development of coding standards for AUTOSAR and RePhrase.

- Worked in a global development team on telecom network management software for optical networks (SONET/SDH) in a Unix environment (mostly C++ on HP-UX and Linux) with a Oracle based database backend.
key technologies used: CMISE, OSI, SQL
- Low-level architectural work: porting of the low-level networking code from HP-UX to Linux; developed a debugging memory management library to facilitate detecting and tracking down of memory management bugs.
key technologies used: low-level networking API on Linux (packet sockets), accessing a program's call stack, reading ELF/SOM symbol table
