Hi, I'm Sang.

I build production automation infrastructure at the intersection of financial operations and software engineering. I turn manual, error-prone workflows into reliable, scalable systems.

Projects

ATLAS v4.0
Sole Developer & Architect — Citi, Operations Risk

Full-stack automation platform I designed and built entirely solo at Citi. Replaced 100% of manual Excel-based reporting workflows with 16+ real-time data pipelines, a live Dash dashboard, and Socket.IO for real-time updates. Production infrastructure handling real risk data daily. Codebase is confidential — architecture and outcomes are mine to share.

ThriveKid
Solo Developer — PWA Side Project
In Development

A Progressive Web App for tracking childhood developmental milestones and wellness goals. Built with a RESTful API backend, Entity Framework Core for data persistence, and a mobile-first PWA frontend. My public-facing engineering proof — the code I can actually show.

About Me

I'm an Applications Developer and Automation Engineer on the Operations Risk team at Citibank in Tampa, FL. My background is unusual — I came from finance (Wells Fargo, Raymond James), then taught myself to build the tools I needed when none existed.

That led to ATLAS — a full-stack internal platform I designed from scratch and maintain entirely solo. It replaced a fragile manual reporting operation with 16+ automated pipelines and real-time infrastructure that my team depends on daily.

Outside of Citi, I'm building ThriveKid — a PWA that shows what I can do when the code is mine to share publicly. I'm also finishing a B.S. in Computer Science at WGU, with a transfer credit strategy that puts me on track for late 2027.
