Jeffrey Cheng is a software engineer with nine years of experience building scalable backend systems and customer-facing frontends, currently at Lendbuzz after several impactful years at Wayfair. He has productionized operations research models and automation that cut scenario generation from hours to under ten minutes, and led frontend decoupling and micro-frontend planning for sales and service agent apps. His work spans full-stack engineering, CI/CD, horizontal scaling, and integrations with third-party chat and workforce systems, showing a knack for operationalizing complex workflows. Earlier contributions to the open-source DDF project emphasize secure backend design—he implemented deserialization safeguards and improved test coverage—demonstrating both security sensibility and attention to reliability. Comfortable refactoring legacy stacks and modernizing toolchains, he pairs pragmatic engineering with clear documentation and process improvements. Academically grounded in computer science and mathematics from Boston College, he brings a systems-minded approach to shipping maintainable, production-ready software.
