• Led two to three concurrent client engagements as the client-facing technical lead, owning architecture decisions, delivery quality, and risk on each. Four in total across Entertainment, Finance, Healthcare, and Real Estate, including a HIPAA-constrained provider platform, across Azure, AWS, and GCP.
• Entertainment: led a Snowflake-to-Databricks migration onto a medallion architecture, and built the validation framework that became its sign-off gate: 114 automated checks across 678M migrated rows, catching a live source-side load error the source system never surfaced. Then designed the gated, 22-subagent agentic workflow built to carry that standard to the wider estate.
• Engineered and presented the Databricks proof of concept behind a ~$1.5MM Microsoft and Databricks ECIF proposal in Finance. In Real Estate, owned the code analysis, the ~6,800-hour effort model, and the orchestration proof of concept that converted a five-week assessment into an executed SOW with partner funding approved.
• Set the Databricks delivery standard the engagement teams built inside, covering workload translation, validation, testing, and deployment. Enforced it through review on every engagement, and built the Model Context Protocol and Claude Agent SDK tooling that automates it.
• Mentored data engineers and visualization developers across engagement teams of 3–6, providing technical guidance and code review.

• Completed the MIT xPRO Professional Certificate in Data Engineering, a multi-course program assessed on graded work.

• Established the data governance framework: anomaly detection, CI/CD-enabled quality checks, version control, and gold-metric certification, so leadership trusted the numbers it acted on.
• Developed and automated 15+ Databricks pipelines integrating IoT and SaaS sources, contributing to a 50% EBITA increase (~$50M) and a multi-million-dollar ARR customer win.
• Served as Scrum Master for two geographically dispersed US and EU data science teams, shaping shared development practices across time zones.
