Rockstar🎓
Top SchoolChristopher Sasarak is a software engineer with 10 years of experience building across the full stack—from PHP-backed websites and JavaScript front-ends to Haskell-based analytics and ETL systems. He combines a product-focused mindset with research and experimental-development experience, having shipped CRM features, course-promotion platforms, and a math-expression search interface while collaborating closely with product managers and designers. At FOSSA he contributed backend dependency and license analysis support for many ecosystems (including Composer, Gradle, Cargo and Ruby), demonstrating practical automation and multi-build-system integration skills. Comfortable in both OOP and statically-typed functional paradigms, he has optimized concurrent HTTP APIs and memory-efficient ETL pipelines using Haskell tooling like Servant, Opaleye and Conduit. Based in Chicago, he seeks roles that blend diverse technical challenges with opportunities to advance functional programming in production.

Contributions summary:Christopher primarily focused on implementing dependency analysis features for various build systems and package managers. Their contributions included the development of a Composer (PHP) license detection strategy, parsing and analyzing dependencies from `composer.json` files. They also worked on integrating Gradle build system support, including settings.gradle detection, and expanded support for package-lock.json files and associated parsing logic. Additionally, they added support for detecting licenses in Cargo.toml and Ruby gemspec files, alongside adding a new dynamic strategy that relies on the use of `conda env create` and parsing of the output.
