Manoel Marques is a seasoned software engineer based in New York with nine years of experience building and leading application development in Web 2.0, mobile computing, and enterprise content management. He is fluent in Python, Java, Swift/Objective-C, C++, and JavaScript and comfortable across iOS and Android stacks as well as major IDEs like Xcode and PyCharm. Manoel has made substantive back-end and test-automation contributions to the prominent open-source Qiskit ecosystem, improving optimizers, refactoring tooling, and hardening unit tests for quantum computing libraries. His work often focuses on code quality, dependency management, and practical ML model features—skills reflected in fixes to linting, recursive dependency lookups, and QSVM enhancements. Drawing on an electronics engineering background and a master's in computer science, he blends low-level rigor with application-level product thinking. Notably, he frequently operates behind the scenes to keep complex scientific codebases maintainable and up-to-date with evolving APIs.
