Experience
Software Development Engineer I
House Works Technology — Remote
Feb 2025 - Present (promoted from intern, Apr 2025)
- • Led a greenfield authentication and authorization platform end-to-end, owning architecture, authorization modeling, service integration, rollout, and production deployment
- • Built and operated self-hosted Keycloak in production — deployment, configuration, upgrades, backups, and operational maintenance; developed custom Java SPIs, providers, and extensions for business-specific identity requirements
- • Designed fine-grained authorization using SpiceDB (Google Zanzibar model), defining a ReBAC model spanning 16 object types and 45 permissions and integrating authorization checks across Django/DRF APIs
- • Implemented multi-tenancy with Keycloak Organizations and tenant-aware authentication; built IdP Federation with domain-based SSO to route users to their enterprise identity provider based on email domain
- • Kept the SpiceDB authorization graph consistent with PostgreSQL using a transactional outbox and asynchronous worker, with reconciliation and consistency mechanisms to detect and repair authorization drift
- • Architected a real-time multilingual voice transcription and translation pipeline in a production EHR, streaming audio through Azure Speech into structured clinical records in PostgreSQL and serving 1,000+ patients
- • Own the backend stack (Django, DRF, PostgreSQL, AWS) handling 10K–100K requests/day; designed production infrastructure with Terraform, Docker, AWS EC2, and GitHub Actions CI/CD, reducing deployment time from ~45 min to ~12 min (~70%)
- • Set up observability with Sentry, ClickHouse, and Grafana; migrated legacy Django views to DRF ViewSets (~40% less boilerplate), write Pytest unit/integration tests, review code, and ship React.js/Next.js features end-to-end
