Lindsay Holmwood developed and maintained the cipherstash/proxy and cipherstash/encrypt-query-language repositories, focusing on robust CI/CD automation, containerized testing, and developer onboarding. Over eight months, Lindsay delivered features such as multi-architecture Docker builds, automated Postgres environment management, and comprehensive integration testing using Go and Rust. By refining configuration management and documentation, Lindsay reduced environment drift and improved onboarding speed. The work included implementing version tracking, Prometheus metrics, and secure release pipelines, leveraging technologies like Docker, GitHub Actions, and PostgreSQL. Lindsay’s engineering approach emphasized reliability, maintainability, and cross-platform support, resulting in stable deployments and streamlined development workflows across the projects.

Month: 2025-09 — cipherstash/proxy: Focused on stabilizing PostgreSQL-related environments and improving CI reliability through version management and automation. Key actions delivered include pinning Docker containers to PostgreSQL 17 to prevent PG18 breakage and updating Docker Compose to auto-pull the latest postgres:17 image. These changes reduce environment drift, enable early compatibility testing, and lay groundwork for PG18 support in a controlled release.

February 2025 for cipherstash/proxy focused on strengthening testing, configuration clarity, and observability to accelerate safe deployments and reduce risk. Major work delivered across Go integration tests, Postgres data-type mapping tests, and extensive doc improvements, with concrete business value in reliability, onboarding, and operational metrics. Key features delivered: - Go integration tests and infrastructure improvements: more reliable integration tests, added setup/README, helpful errors, data insertion tests, and multi-run capability. - Configuration lookup order, minimal config, and documentation enhancements: explicit configuration lookup sequence, deduplicated options, defined minimum config for file and env sources, and standardized environment variable naming. - Golang integration tests for mapping data types: end-to-end tests for mapping text, integers, floats, and dates across all Postgres modes. - Test infrastructure enhancements for Golang mapping tests: flexible connection setup, subtests for insert and select, longer CI timeouts. - Metrics/docs alignment and Prometheus readiness: aligned metric descriptions, added Prometheus fallback and enablement controls (including TLS proxy), and comprehensive documentation updates. Major bugs fixed: - Disable integration tests for mapping dates - Fix link formatting in docs - Fix typos and capitalization inconsistencies in docs - Bug: Config serialization issues Overall impact and accomplishments: - Significantly improved CI reliability and test coverage, reducing flaky deployments and speeding feedback loops. - Clearer, more actionable configuration guidance leading to faster onboarding and fewer misconfigurations. - Enhanced observability with Prometheus metrics enablement, enabling better monitoring and faster incident response. - Stronger data-type mapping validation across Postgres modes, increasing confidence in data integrity. Technologies/skills demonstrated: - Go and Golang test infrastructure, PostgreSQL integration testing, CI/CD/test infra improvements, Prometheus/metrics exposure, and documentation best practices.
