Open-Source Contributions
=========================

For better or worse, I have spent a significant part of my software engineering career working on proprietary applications; therefore, my contribution to open-source is rather small. 

Background support for Gherkin in JEST
------------------------------------------------------------

    Behavior Driven Development has proven itself to be a robust method for managing synchronization between specification and implementation. For the `TypeScript <https://www.typescriptlang.org/>`_ based project that I've been working on, I gound a great `JEST <https://jestjs.io/docs/en/getting-started>`_ `extension supporting Gherkin <https://github.com/bencompton/jest-cucumber>`_. Unfortunately, `the original project <https://github.com/bencompton/jest-cucumber>`_ was missing reusable background implementation. I have added the missing code in a `GitHub fork <https://github.com/ian7/jest-cucumber>`_. 

technologies:
    BDD, JavaScript, TypeScript, Gherkin, NodeJS


OpenAPI generator for NodeJS/Express
------------------------------------

    API Standardization with OpenAPI/Swagger has grown to be a must in a distributed systems' landscape. Due to the development team constraints, the system I contributed to used TypeScript/NodeJS in the backend. I have contributed `minor changes <https://github.com/OpenAPITools/openapi-generator/pull/3802>`_ to the OpenAPI-generator making it operational in Windows-based environment. The generator was further customized (forked) to meet project-specific backend stack set-up, that couldn't be merged back to the original project. 
    
technologies:
    Java, JavaScript, OpenAPI v2, Swagger



NodeJS based reverse-proxy bugfix 
---------------------------------

    I've been using NodeJS based reverse-proxy for ingress routing of production deployments for the Software Architecture Warehouse. As `described in the SAW Development blog <http://development.blog.saw.sonyx.net/2012/11/http-delete-failing-with-411.html>`_ I have found that the proxy doesn't pass a content-length parameter for DELETE requests that were essential for my application.
