Embodiments of the invention are directed to a system, method, or computer program product structured for synthesizing and building infrastructure platforms. In some embodiments, the system is structured for performing a natural language synthesis of a proposed upgrade to existing infrastructure platform(s), where the natural language synthesis includes analyzing, using natural language processing, code of the proposed upgrade; generating a trust score indicating a predicted likelihood of success from results of the natural language synthesis; in response to the trust score being above a threshold, identifying, using natural language processing, inactive code in the platform(s); generating a build automation script for deploying the proposed upgrade to create upgraded infrastructure platform(s) that exclude the inactive code; executing the build automation script; capturing data from the build automation script execution; and using the result of the build automation script execution and the captured data to refine the natural language synthesis.
