I build full-stack web platforms, APIs, and data workflows with React, Node.js, and PostgreSQL.

At Dark Alpha Capital, I built core features for a proprietary web platform using React and Node.js, launching four sector-specific content modules and expanding the platform’s content coverage.

I designed PostgreSQL schemas, backend services, REST APIs, and SQL queries that transformed business data into structured administrative workflows. I also implemented bidirectional processes for evaluating partnership opportunities, updating business records, and preserving data integrity through validation and error handling.

Alongside industry work, I support 800+ students each semester as a Senior Course Associate for UIUC’s CS 124 course. I lead instructional sections for classes of 130+ students, improve teaching workflows, and train junior course assistants.

I’ve also built a full-stack group expense splitter and an image-processing mosaic generator, including a KD-Tree optimization that reduced mosaic rendering time by 30%.
