Summary
👤
Senior🎓
Top SchoolJaved Nissar is a Senior Software Engineer based in New York with 12 years building scalable backend platforms and large-scale web applications. He blends pragmatic production engineering at fintech and marketplace companies (Ramp, Faire, Shopify) with hands-on open-source contributions in Rust—adding geospatial algorithms and parallelized map-import features to notable projects like georust/geo and a-b-street. Comfortable across JVM, Go, Python, and Rust ecosystems, he has led cross-team migrations (translations extraction), built ML/LLM prompt-evaluation tooling, and delivered measurable business impact such as cost savings and reduced transactional email volume. A strong advocate for operational reliability and developer velocity, he pairs low-level algorithm work (concave hulls, traffic simulation) with product-minded delivery.

Role in this project:
Back-end Developer
Back-end DeveloperContributions:8 reviews, 10 commits, 3 PRs in 2 months
Contributions summary:Javed implemented a concave hull algorithm for geospatial data within the `geo` crate. Their work involved significant code modifications, adding a `concave_hull` function to various geometry types and refining the algorithm based on feedback. They also added a benchmark for performance testing. The user's contributions focused on enhancing the crate's capabilities for spatial data processing and analysis.

Transportation planning and traffic simulation software for creating cities friendlier to walking, biking, and public transit
Role in this project:Full-stack Developer
Full-stack DeveloperContributions:3 reviews, 6 commits, 6 PRs in 7 months
Contributions summary:Javed contributed to multiple aspects of the `abstreet` project. They parallelized map import jobs using Rust's threading capabilities. They also implemented features within the ezgui library, including edge auto-panning for map navigation and adding an options panel. The user refactored the event update loop and added traffic simulation to the title screen for a more engaging user experience.
