• Build and maintain Node.js/TypeScript REST APIs backed by PostgreSQL for customer workflow products. • Cut p95 API latency 28% by introducing Redis caching, query tuning, and targeted indexes across high-traffic endpoints. • Shipped authentication and authorization service endpoints with audit logging and rate limiting, supporting 12K+ monthly active users. • Strengthened CI with parallel Jest suites, Docker-based integration tests, and coverage improvements from 68% to 87%. • Participate in a light on-call rotation, writing runbooks and resolving production issues with clear post-incident follow-up.

• Implemented REST endpoints for patient scheduling workflows in Node.js and TypeScript, reducing manual scheduling steps for support staff by 35%. • Designed and reviewed SQL migrations for appointment, provider, and availability data in PostgreSQL with rollback-safe deployment scripts. • Added 42 Playwright and Jest tests for scheduling edge cases, authentication flows, and regression coverage. • Partnered with product and QA to document API contracts, triage defects, and release incremental improvements every two weeks.

• Held weekly office hours and guided 80+ students through asymptotic analysis, trees, graphs, hashing, and dynamic programming. • Graded programming assignments and exams using consistent rubrics, returning actionable feedback within one week. • Supported lab sessions, debugged Java and Python implementations, and escalated recurring concepts to course staff. • Created short practice problems and review notes that improved quiz readiness and reduced repeat questions during exam weeks.

Coursework: Data Structures, Algorithms, Database Systems, Distributed Systems. Capstone: built a monitored scheduling API with TypeScript and PostgreSQL.
