PROFILE

Matt Gotteiner

Matthew Gotteiner developed and maintained retrieval-augmented generation systems and access control documentation across the microsoft/rag-time and MicrosoftDocs/azure-ai-docs repositories. He built end-to-end RAG workflows in Python, integrating Azure AI and OpenAI APIs, and delivered Jupyter Notebooks that demonstrated advanced search strategies and agentic query handling. His work included dependency management improvements and configuration management using TOML and YAML, ensuring reproducible builds and scalable deployments. Matthew also authored and refined technical documentation on RBAC, ACLs, and concurrency, clarifying OAuth 2.0 token scopes and error semantics. His contributions improved onboarding, security guidance, and developer experience through targeted, incremental engineering and documentation updates.

August 2025

4 Commits • 1 Features

Aug 1, 2025

August 2025 monthly summary focused on advancing developer experience for Azure AI Search by delivering targeted documentation improvements in the MicrosoftDocs/azure-ai-docs repository. The work enhances clarity around concurrency, resource update serialization, and error semantics, and ensures navigation stability across the documentation site.

Jun 1, 2025

June 2025 monthly summary focusing on business value and technical achievements across two repositories. Key features delivered: - Rag-Time: Dependency management hardening by pinning azure-ai-projects to 1.0.0b10 and ensuring a trailing newline in requirements.txt, improving packaging hygiene and reproducibility of builds. - Azure AI Docs: Documentation updates for Azure AI Search access control, clarifying ADLS Gen2 permission mappings (RBAC, ABAC, ACLs, and Security Groups) for document-level access control, and restoring guidance on OAuth 2.0 access token scope. Major bugs fixed: - No critical code defects reported this month. Where applicable, minor documentation corrections were implemented to prevent guidance drift; the azure-ai-docs update included a revert to restore authoritative guidance, ensuring accuracy in access-control documentation. Overall impact and accomplishments: - Strengthened release reliability and packaging hygiene, reducing risk of dependency drift in production environments. - Improved customer understanding and security posture for data access through clearer access-control documentation and correct OAuth2 scope guidance. - Demonstrated end-to-end quality control via targeted commits (one dependency pin with a hygiene change; two docs commits including a revert) across two prominent repositories. Technologies/skills demonstrated: - Python packaging management and requirements.txt hygiene; dependency pinning - Documentation best practices; RBAC/ABAC/ACL concepts; OAuth 2.0 token scopes - Change management with targeted commits to ensure stability and accuracy

Feb 1, 2025

February 2025 monthly summary focusing on business value and technical achievements across two repositories: microsoft/rag-time and MicrosoftDocs/azure-ai-docs. Key outcomes include delivering a hands-on RAG Time 2 Jupyter Notebook with Azure SDK setup and credentials, a pandas-based results viewer, and demonstrations of multiple search strategies (keyword, vector, hybrid, and semantic) with query rewriting; and documentation improvements clarifying API versions, deprecation notices, and distinctions between data plane and management plane APIs, including a corrected link. These changes accelerate RAG pipeline development, improve developer onboarding, and reduce API migration risk.
