About

I’m a software engineer based in Toronto with 2+ years of experience building secure backend services, full-stack web applications, and AI evaluation pipelines. I work with Python (FastAPI, Django), TypeScript/JavaScript (React/Next.js), and PostgreSQL to deliver tenant-aware, authenticated systems with background processing, testing, and observability.

I also have hands-on experience training and evaluating AI outputs—designing coding and multimodal task evaluations, ranking responses, and writing scoring rationales to improve data quality. I enjoy collaborating across product, frontend, and ML teams, improving deployments on GCP Cloud Run with CI/CD, and turning requirements into reliable, well-documented features.
