Summary
🤩
Rockstar🎓
Top SchoolAJ Lewis is a seasoned Senior Computer Scientist with 14+ years designing and hardening distributed storage, DevOps, and user-facing systems across Linux, macOS, and Windows. He blends low-level C/C++ systems work—evidenced by cross-platform ZeroMQ contributions improving memory handling and build portability—with full-stack skills in Python, Ruby, PHP, JavaScript/Angular, and container/virtualization tooling like Docker, VMware and KVM. A proven independent contributor and refactorer, AJ led UI and usability teams at Quantum and now drives engineering effort at Adobe, participating in two successful acquisitions along the way. He’s especially strong at untangling legacy code and making it robust and portable, often addressing platform-specific compiler and allocation edge cases that others miss.

High-level C binding for ØMQ
Role in this project:
Back-end Developer
Back-end DeveloperContributions:71 commits, 1 PR, 1 push in 3 years 9 months
Contributions summary:AJ primarily focused on improving the memory management and error handling within the `czmq` library, a high-level C binding for ØMQ. Their contributions included adding a new `#define` option for propagating allocation errors and modifying the `zctx`, `zmsg`, `zframe`, `zsocket`, and `zthread` modules to check for memory allocation failures using `zmalloc`. They also refactored code for string handling within `zmsg` and addressed several memory-related issues, enhancing the stability and robustness of the library. Further improvements included the refactoring of `zmsg_load` to include error handling.

ZeroMQ core engine in C++, implements ZMTP/3.1
Role in this project:Backend Engineer
Backend EngineerContributions:11 commits, 1 PR in 7 years 4 months
Contributions summary:AJ's contributions primarily focused on improving the build process and ensuring cross-platform compatibility for the ZeroMQ core engine. They addressed build issues on various platforms like AIX, HPUX, and RHEL5/SLES10, adapting the code to specific compiler and system requirements. The user made changes to include necessary header files and correct socket-related data types, demonstrating a deep understanding of build systems and platform-specific nuances within the C++ codebase. These changes ensured the library could be built and run reliably across different operating systems.
