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
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.
Internal tool — codebase confidential per Citi policy
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.

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.
Experience & Education
Experience
Sole engineer behind ATLAS — production automation platform serving the Operations Risk team. Architected and maintain 16+ data pipelines. Replaced 100% of manual Excel workflows.
Sharpened understanding of data integrity, audit trails, and process compliance — principles I later applied when engineering ATLAS.
Built analytical skills and client-facing communication for non-technical stakeholder design.
Education
Let's build
something real.
Open to engineering roles, dev-adjacent opportunities, and builders who ship.
