Roderick D.

Designed, built, and deployed a production application platform end-to-end using Python and Node.js — owning architecture, backend services, REST APIs, deployment, and operations as the lead engineer. Reduced API and inference latency by 75% (2s → 500ms) through targeted refactoring of distributed decision chains — direct performance tuning at the API layer. Achieved 90%+ test coverage across all backend components using Vitest (TDD), demonstrating commitment to clean, maintainable, well-documented code. Authored multi-stage Dockerfiles, managed CI/CD via GitHub Actions, deployed to cloud (AWS) with 99.9% uptime across staging and production environments.

Built and maintained Java and TypeScript components within the Salesforce Flow ecosystem — a high-volume enterprise SaaS platform serving millions of customers — applying enterprise OOP patterns for scalable, maintainable code. Designed and consumed REST APIs across distributed services; led cross-team initiatives spanning 3+ engineering teams in an Agile delivery model. Modernized CI/CD test pipelines with GitHub Actions and Bazel, reclaiming 40+ engineering hours per month by improving reliability and reducing test friction. Extended observability and telemetry across 15+ core components, surfacing runtime performance bottlenecks and configuration errors — directly applicable to enterprise application performance tuning. Mentored teammates through code review and architectural guidance, supporting team-wide delivery quality.
