PROFILE
Mark A. Greenslade
Worked on the worldcoin/iris-mpc repository, delivering backend infrastructure for scalable graph indexing, robust end-to-end testing, and automated deployment pipelines. Leveraged Rust and Docker to implement HNSW-based indexing, dynamic batch processing, and persistent data storage with AWS S3 and PostgreSQL integration. Enhanced CI/CD workflows using GitHub Actions, improved configuration management, and introduced utilities for data-driven testing with NDJSON formats. Refactored code for maintainability, streamlined error handling, and rolled back unstable migrations to ensure reliability. Developed CLI tools and asynchronous service clients to support batch processing and AWS-backed testing, accelerating validation cycles and supporting resilient, production-ready distributed systems in cloud environments.

2 Commits • 1 Features
Feb 1, 2026February 2026 focused on strengthening end-to-end testing capabilities and test automation for the iris-mpc project. Delivered a new End-to-end Service Client for Testing and Batch Request Support, enabling configurable traffic dispatch, AWS-backed testing flows, and batch manual requests with iris codes. This work is backed by two releases (Service Client v0.4.0 and v0.4.1) that include an improved launch script, enhanced batch handling, and codebase simplifications. Refactoring removed mapper.rs and IrisDescriptorOptions to streamline architecture and reduce maintenance risk. No critical bug fixes were reported this month; instead, the focus was on hardening the testing toolchain and expanding testing coverage. Overall, the enhancements accelerate validation cycles, improve test coverage for complex traffic patterns, and increase deployment confidence in AWS environments. The work demonstrates strong capabilities in tooling design, end-to-end testing, batch processing, and codebase cleanups that support faster delivery and higher quality releases.

Oct 1, 2025October 2025 monthly summary for worldcoin/iris-mpc focusing on stability and business value. Key work this month centered on rolling back recent code migrations and utility porting to revert iris-mpc-utils to iris-mpc-cpu changes for generate-benchmark-data, and consolidating CLI and test helpers to known-good behavior. The changes restore original CLI naming (hyphens vs underscores), revert graph-mem-cli and initialise-test-dbs porting, and cleanup obsolete types to reduce downstream fragility.
