High-Impact Data Migration Leadership

Led the final stage of a business-critical project, migrating and translating 100M+ rows of data.

• Tripled team productivity during two critical weeks by doubling my working hours and motivating co-workers to increase their commitments in support of urgent needs.
• Reduced script runtime from 336 hours to 12, optimizing its performance by leveraging my understanding of low-level mechanics in Python, Pandas, and SQL.
• Avoided the typical 2x-5x effort increase in late-stage changes by architecting scalable, testable, and modular software early in the project, ensuring seamless final-stage additions.
• Reduced post-launch fallout from two anticipated weeks of chaos to a few minor issues by prioritizing and mentoring the team in creating a rich automated test suite, covering 95%.

Collaboration and Operation

• Led workshops focused on TDD, AI tools, and PyTest, transforming Friday afternoon lulls into opportunities for knowledge-sharing, further collaborating on advanced SQL and core code principles.
• Doubled collaboration between IT and stakeholders by simplifying and presenting complex topics, resulting in clear, actionable insights and encouraging more engaged discussions and questions.
• Saved weeks of misdirected efforts by developing data visualizations and access tools driving key decisions, enabling secure, independent data retrieval, and freeing up development time.
• Reduced platform downtime from hours per month to mere minutes by automating legacy system deployments, supporting cloud migration, and enhancing DevOps with GitLab CI/CD pipelines.
• Mitigated major cybersecurity risks by a factor of 10 to 1,000 through identifying vulnerabilities, implementing Snyk for dependency monitoring, advocating for best practices, and actively supporting cyberattack responses.
• Eliminated costly knowledge silos by driving documentation from one entry per month to multiple per week through the creation of a frictionless contribution system.
