What I'm looking for

I’m seeking technical roles building scalable backend services and user-facing web features, integrating GenAI/LLM, delivering measurable product impact, and collaborating closely with product teams.

I am a full‑stack software engineer focused on building web platforms and GenAI/LLM prototypes using TypeScript and Python.

At Healthera I launched the web app’s primary revenue driver by developing the clinic prescriptions feature, built a rapid prototype that retained a high‑risk customer, and am delivering a services overhaul to improve performance, SEO, and conversion across 400+ pharmacy sites.

Previously at PwC I developed ETL pipelines with PySpark and Oracle, and built full‑stack chatbot demos using React/Redux, Flask, GPT‑4, LangChain, and LlamaIndex deployed on Azure; I hold a GCP Associate Cloud Engineer certification and a BA with Distinction from UBC.
