Summary
🤩
Rockstar🎓
Top SchoolJustin Wetherell is a lead software engineer with over a decade of experience building high-performance Java and C++ systems for financial services and defense. At Nasdaq he architects scalable data ingest, storage, and query solutions that separate storage scalability (S3, Parquet) from query/computation scalability (Redshift, Athena/Presto). His background includes real-time distributed transaction systems, robotics and AI research at Lockheed Martin, and mission-critical radar and weapons-control software—demonstrating breadth across low-latency systems and embedded/enterprise domains. He mentors teams, drives architecture decisions, and has a hands-on focus on performance and algorithms, evidenced by contributions to a well-known Java algorithms repo. Justin combines deep systems-level expertise with an active interest in blockchain and highly distributed big-data computation. Based in New Jersey, he holds a BS and MS in Computer Science and brings a pragmatic, performance-first approach to complex engineering problems.

Role in this project:
Back-end Developer
Back-end DeveloperContributions:324 commits, 67 PRs, 208 pushes in 6 years 3 months
Contributions summary:Justin appears to be primarily involved in developing and implementing data structures and algorithms in Java. The commits showcase the creation and modification of various data structures like trees, heaps, lists, queues, stacks, and hashmaps. The user also contributes to testing and timing the performance of these data structures using JUnit and focusing on optimizing performance by implementing different variations (e.g., in-place vs. not-in-place sorting). Additionally, the user made changes to several algorithms, including connected components, the Edmonds-Karp algorithm, and the implementation of the A* search algorithm.
