William Glas

Senior Software Engineer · San Francisco, CA

• Architected developer automation and repository-management platforms using Node.js, TypeScript, Python, React, GraphQL/REST APIs, webhooks, PostgreSQL/MySQL, Redis, and GitHub Actions, supporting high-volume repository, CI/CD, and developer workflows.
• Built end-to-end GitHub Apps and Actions integrations with Node.js, TypeScript, Octokit, GraphQL, webhooks, Redis, and relational databases, implementing authentication, asynchronous processing, caching, rate limiting, retries, and event-driven automation.
• Engineered GitHub Codespaces developer workflows using Python, containerized environments, GitHub Actions, Docker, Kubernetes, and cloud infrastructure, automating repository setup and environment provisioning; GitHub reported reducing setup time from roughly 45 minutes to ~10 seconds through prebuilds.
• Developed GitHub Copilot-powered engineering workflows using Python, LLM APIs, repository-aware retrieval, tool calling, streaming responses, and automated evaluation, integrating AI capabilities with developer context and workflows associated with 55% faster task completion in GitHub research.
• Built high-performance GitHub Code View and pull-request experiences using React, TypeScript, GraphQL/REST APIs, client-side caching, virtualization, and lazy loading, helping reduce rendering of an ~18,000-line file from roughly 27 seconds to under 1 second.
• Designed scalable application architecture across Node.js/Python services, PostgreSQL/MySQL, Redis, React, and asynchronous processing, applying indexing, transactions, caching, background jobs, and resilient API patterns for high-volume developer workloads.
• Led cloud-native delivery using AWS, Azure, Docker, Kubernetes, Terraform, and GitHub Actions CI/CD, automating infrastructure, deployments, horizontal scaling, secrets management, monitoring, and production recovery across distributed services.
• Owned products from system and API architecture through backend/frontend implementation, database design, automated testing, deployment, observability, and production support, collaborating across engineering teams and mentoring developers on platform and distributed-system patterns.
