PROFILE
Bartek Gorny
Worked extensively on esl/MongooseIM, delivering features and fixes that improved messaging reliability, privacy, and developer workflows. Focus areas included transitioning to a GraphQL-first API, enhancing traffic monitoring, and strengthening privacy logic for XMPP messaging. Applied Erlang and GraphQL to implement robust backend modules, expand test coverage, and streamline CI/CD pipelines using CircleCI and Docker. Addressed race conditions, improved message archiving, and maintained code quality through static analysis and documentation updates. The work emphasized maintainability and scalability, reducing release risk and supporting faster iterations, while deprecating legacy REST APIs and ensuring secure, efficient real-time messaging across the platform.

Mar 1, 2026March 2026 (Month: 2026-03) — Focused on maturation of GraphQL flows, security, and maintainability for esl/MongooseIM. Key features delivered include GraphQL Subscriptions and Traffic Management Enhancements, introducing a dedicated traffic management service, expanded admin capabilities for managing subscriptions and traffic data, and clearer traffic hooks. Also completed GraphQL Security Enhancements and REST API Deprecation, enhancing message verification, adding stronger admin tools for user management, and removing deprecated REST endpoints. A parallel maintenance effort cleaned the codebase by removing debug tools, unused functions, and outdated Swagger docs to streamline operations. ### Business impact - Improved scalability and reliability of GraphQL subscriptions and traffic handling, stronger security posture, and a leaner, easier-to-maintain codebase. Release readiness achieved with a 6.6.0 prep cycle. ### Technologies/skills demonstrated - GraphQL (subscriptions, security), admin tooling, traffic management patterns, REST API deprecation, code cleanup, release engineering, version control discipline.
