What I'm looking for

I seek roles building reliable, scalable backend or full-stack systems that integrate AI, emphasize observability, and offer mentoring and ownership opportunities.

I am a senior software engineer with 12 years' experience building reliable, production-grade systems across enterprise, platform, automation, and healthcare AI domains. I specialize in Python backend and full-stack development (FastAPI, Django, async patterns), integrating ML models into user-facing products while prioritizing performance, safety, and maintainability.

I have led re-architecture efforts, optimized database schemas and background processing, and improved real-time UX with WebSockets and robust state management. I mentor engineers, author runbooks and observability dashboards, and operate AWS-backed services to ensure systems withstand real-world usage and high-concurrency clinical and automation workloads.
