- Migration Pipeline: Owned end-to-end design and delivery of compliance-record migration from Convercent to OneTrust, orchestrating phased validation across DEV → QA1 → QA2 → PROD with zero data loss and zero production incidents.
- API Architecture: Architected Kubernetes-deployed Django REST endpoints handling concurrent ingestion at scale, implementing idempotent writes, schema validation, and transactional rollback across millions of compliance records.
- CI/CD Excellence: Designed Jira-triggered CI/CD pipelines (Python · Django · Kubernetes) cutting release cycle time by 60%, enabling multi-environment deployments in under 30 minutes with full auditability.
- Code Quality: Audited three legacy services, restoring test coverage from near-zero to 80%+, adding type annotations, and authoring engineering standards now adopted team-wide.
- AI Chatbot: Led backend development of an AI-powered chatbot (Langchain · FastAPI · HuggingFace LLMs) enabling natural-language queries over security scores, designed, built, and shipped to AWS production in 6 weeks.
- Platform Ownership: Sole backend owner across three Django systems (platform API, support portal, intranet), shipping features weekly while sustaining reliability for security-critical product.
- Test Coverage: Restored abandoned test suites across all three repos from 0% to production-grade coverage, unblocking a major platform refactor.
- Developer Experience: Containerized internal support toolset with Docker, cutting engineer onboarding time from hours to under 60 minutes.
