Emma Wang

I’m a senior software engineer with 12+ years building full-stack, data-rich platforms across consumer and enterprise products. I’m hands-on across the stack—React and TypeScript on the frontend, and Python-based services (FastAPI/Django) with PostgreSQL-backed storage on the backend.

I focus on reliable, testable delivery by implementing integration and end-to-end testing (Vitest/Playwright) plus observability to ensure correctness and scalable operations. That includes building strong data pipelines and workflow orchestration with Temporal, containerized deployments via Docker, and CI/CD to keep releases safe and repeatable.

Most recently, I built major GenAI-native capabilities for a financial research platform: an LLM-powered context engine with Retrieval-Augmented Generation, compliance guardrails to prevent unsolicited recommendations, and role-based access control backed by PostgreSQL/Redis. I also shipped agentic research workflows and scheduled report generation orchestrated with Temporal—reducing average research task completion time by approximately 12% through context retrieval and query optimization.

Earlier at a global social media platform, I helped deliver end-to-end features from camera and real-time experiences to discovery, notifications, and media pipelines at massive scale. I improved delivery reliability by approximately 11%, worked across OAuth/permissioned systems and privacy controls, and strengthened platform quality through automated testing and observability.
