Senior🎓
Top SchoolJohn Sweeney is a Lead Software Engineer with 11 years of hands-on experience building robust, well-documented systems and shipping production software at DraftKings. He blends pragmatic engineering with a perfectionist attention to testing, documentation, and organized development practices, often refactoring and toolifying processes to save developer time. Comfortable across the full stack, he has designed scalable APIs, asynchronous data import pipelines, Dockerized deployments, and interactive React front ends for analytics products. As a co-founder of AAUStats he built specialized sports analytics tooling and a flexible data model to handle diverse league structures—an early sign of his ability to translate domain complexity into reliable software. He learned by experimentation and application, favoring practical proofs over theory, and pairs technical depth with strong written communication to make designs and trade-offs clear. Based in Boston, he brings resourcefulness and a habit of improving imperfect systems into every engineering role.
