- Built and shipped DDSI's AI code reviewer for GitLab (Amazon Bedrock): automated reviews when a merge request opens and on each later commit, meta reviews and insights, and on-demand commands from merge-request comments; thousands of reviews across dozens of onboarded projects.
- Designed the reviewer: language-agnostic through AST parsing across many languages, grounded in a knowledge base with RAG embeddings, and self-improving, as contributor feedback tunes each signal's confidence threshold until it becomes a learned rule; FrugalGPT-style model cascading keeps inference costs down.
- Built and launched DDSI's multi-tenant hosting platform on AWS, including AWS Cloud Map: any GitLab repo goes live on a Streamlit, Python, Dash (Plotly), or JavaScript runtime, with a growing set of apps already live.
- Led and mentored 5+ people since Dec 2023 as Application Engineering Manager (retitled Lead Application Engineer in 2026) and resolved questions and decisions for other areas of DDSI, directly or through work produced.
