Aarjun contributed to multiple Meta repositories, including facebook/fboss, by building and optimizing CI/CD pipelines, automating build and test workflows, and enhancing cross-platform compatibility. He implemented AI-assisted code review optimizations and migrated legacy Thrift libraries to modern thrift-python, using C++, Python, and CMake to streamline build systems and dependency management. Aarjun addressed OSS build failures, improved test categorization, and expanded hardware test coverage, ensuring reliable release processes and maintainable codebases. His work included developing generic CMake modules for migration tooling and automating runtime discovery of dependencies, reflecting a deep understanding of backend development, build automation, and software testing.
April 2026 highlights: Implemented CentOS Stream 9 fbthrift-python build compatibility and migration tooling across multiple repositories, introduced a generic CMake module for thrift-python migrations, improved runtime discovery of thrift-python and folly-python, and enhanced packaging for C extensions. Addressed critical OSS build issues and improved test reporting and fan-service integration tests, boosting reliability and deployment readiness.

March 2026 monthly summary focusing on business value and technical achievements across six repos. Key outcomes include cross-repo CI build optimizations to skip on-diff getdeps when only Devmate AI-assisted LLM rule files change, leading to faster feedback cycles and lower CI costs; OSS compatibility stabilization in FBOSS with new code-review checks; thrift library migration work with a controlled rollback to ensure OSS compatibility; and documentation enhancements for agent run modes and AI-assisted workflows. Demonstrated strong proficiency in CI/CD tooling, build system hygiene, cross-repo collaboration, and effective risk management in migrations.

January 2026 (facebook/fboss) — Key features delivered: Wiki Documentation Deduplication for Test Categorization (bug fix) — removed duplicate test entries to ensure each test appears in a single category, improving clarity and consistency in test categorization. Major bugs fixed: Eliminated duplicate Wiki entries that caused misclassification and confusion in test categorization. Overall impact and accomplishments: Clearer test categorization enhances QA efficiency and automation reliability, enabling faster test planning, execution tracing, and reporting. Maintained a strong collaboration and traceability with review by KevinYakar and differential revision D91499347. Technologies/skills demonstrated: Git version control, wiki/documentation maintenance, code review discipline, differential revision process, and cross-team collaboration.
