PROFILE
Bartek Gorny
Worked on the esl/MongooseIM repository to deliver robust backend and API improvements over four months, focusing on messaging reliability, privacy, and developer experience. Introduced GraphQL as the primary API interface, deprecating legacy REST endpoints and providing migration documentation to streamline adoption. Enhanced privacy management and message archiving by refining stanza ID handling and optimizing privacy checks, using Erlang and GraphQL. Improved CI/CD pipelines with CircleCI and expanded Dialyzer-driven test coverage, increasing build reliability and code quality. Addressed race conditions and test flakiness, updated dependencies, and maintained clear documentation, resulting in a more stable, maintainable, and developer-friendly real-time messaging platform.

Feb 1, 2026February 2026 — Delivered a GraphQL-first API strategy for esl/MongooseIM, accompanied by deprecation/removal of REST-based interfaces and targeted documentation improvements. Key outcomes include making GraphQL the primary interface, deprecating admin REST and removing client REST, and publishing a migration guide to ease onboarding for developers. Major stability and quality improvements were achieved through fixes to messaging archiving and test reliability. Business impact includes reduced API surface for maintenance, faster developer adoption of GraphQL, and more reliable message routing and retrieval across modules.

Jan 1, 2026January 2026 (esl/MongooseIM) focused on stability, search quality, and pipeline reliability. Key outcomes include: robust stanza ID management with tests and documentation; XEP-0431 full-text search and archiving improvements; a regression-safe registration race-condition fix; enhanced MUC tests with realistic PIDs and privacy considerations; and CI/test infrastructure enhancements to enable larger builds and broader coverage. Additional maintenance updates updated dependencies (packaged versions of escalus and wait_helper) for long-term stability. Overall impact: more reliable messaging workflows, faster and more accurate search/archiving, stronger quality gates, and a maintainable codebase with improved developer productivity.

Apr 1, 20202020-04 Monthly Summary: Privacy and server-to-user IQ delivery improvements in esl/MongooseIM. This month focused on correcting privacy logic to permit server-originated IQ stanzas to reach users, while preserving privacy against other users. Implemented with a targeted bug fix and added assertions to validate delivery of server-sent stanzas, improving server communication flow and reliability. No new user-facing features were released; the changes strengthen core messaging reliability and privacy guarantees.
