Staff Software Engineer at EDB (Enterprise DB)

April 1, 2025 - Present

Owned build, release, and CI/CD for ClickHouse MCP integration. Implemented static analysis and code quality via SonarQube and ran PGAA build and test pipelines across arm64 and amd64. Picked up Rust for performance-critical components. Built reproducible test infrastructure using a single-command Docker stack (Postgres, MinIO with Lakekeeper/Iceberg catalog, dbt TPC-DS kit, Spark). Ran TPC-DS power tests at different scale factors and compared engine configurations with Docker layer caching to keep rebuilds fast. Improved and maintained PGAA (Postgres Analytics), an engine extension for columnar query execution, reading Iceberg objects from object storage, and shipped defect fixes and enhancements with unit and integration test coverage. Used AI-assisted development (Claude and GitHub Copilot) for code/tests/docs while maintaining project conventions and guardrails, validating outputs against tests and CI before review.

Senior Software Engineer at IBM — Cloudant

January 1, 2015 - April 1, 2025

Owned multi-language build, test, and release paths for client libraries used by Cloudant external developers (JavaScript, TypeScript, Go, Python, Java). Migrated team code from hand-written per-language libraries to libraries generated from a single spec, reducing release effort and language drift, including real customer migration to new SDKs. Rescued CI/CD across teams: brought down an existing backlog of failing pipelines and tests, partitioned and parallelized slow suites, tracked down flaky tests, and got pipelines back to green while influencing a shared codebase. Built automated unit/integration/contract testing frameworks and CI pipelines (Jenkins, Travis CI, GitHub Actions) with quality gates (SonarQube) and published builds to Artifactory across supported languages. Owned API design and OpenAPI specs and developer documentation, supported onboarding and knowledge sharing across years. Handled production support and incident response using Splunk and IBM Cloud tooling, tra

Software Engineer at IBM

October 1, 2010 - January 1, 2015

Took significant ownership designing, building, and releasing the DB2 Database Conversion Workbench and an Eclipse desktop application for Oracle-to-DB2 migration, including Java UI and the PL/SQL/SQL logic. Owned a tool that continuously syncs and transforms Cloudant data into an IBM DB2 data warehouse near real time and expanded Cloudant integration on IBM’s Functions-as-a-Service platform. Supported Fortune 500 customers with sizing/proofs of concept and mentored interns.
