What I'm looking for

I'm looking to build software and AI-enabled products where I can apply backend, full-stack, and model-evaluation experience, keep learning new frameworks, collaborate closely through GitHub and Jira, and solve technical problems with practical fixes.

I've supported Charles Schwab's Compliance and Legal Systems backend through Infosys, resolving over 220 ETL workflow service requests and handling pre-production deployments, troubleshooting, and emergency requests. As a specialized programming contractor, I've trained AI chatbots across more than 300 small-scale applications by evaluating model responses, writing unit tests, and dockerizing codebases.

I'm currently building Percepty, an educational platform that combines React, Manim, and Express to help students learn mathematics through programming. My work also includes Flask, PostgreSQL, GCP, neural-network experiments for Japanese kana recognition, and practical SwiftUI and Python applications.
