Void.GG — technical leadership
Led architecture and delivery across web, mobile, backend, and real-time esports systems. Improved performance and deployment workflows while helping a 14-person team deliver.
X Games — full-stack engineering
Built live-stream access controls, geo-aware experiences, and Google Ad Manager integrations for a sports media platform with demanding event windows.
Smith Commerce — storefront modernization
Rebuilt Marcone’s storefront around headless commerce, performance, and accessibility, with modular boundaries that let teams work independently.
Optic Power / Codepwr — product engineering
Shipped across gaming and SaaS products, including Team Liquid, NurtureBoss, and Stardust.gg, with work spanning APIs, frontend architecture, and performance.
I build tools around problems I encounter in my own projects: consistent interfaces, useful feedback, and dependable delivery.

- Stay hands-on. Connect architecture decisions to the code, the product, and the people maintaining it.
- Make quality repeatable. Use tests, accessibility checks, clear documentation, and release automation to shorten feedback loops.
- Respect the user. Treat performance, privacy, and understandable interfaces as part of the product.
My core stack is TypeScript, React, Astro, Node.js, and Cloudflare. My product work also spans Swift / SwiftUI, Kotlin / Compose, React Native, and Rust tooling.
I write about the systems I build and the tradeoffs behind them. Start with:
- How I Built the santi020k Developer Tool Ecosystem — How the tools connect across real projects.
- Why Developer Experience Work Should Be Measured Like Product Work — Making engineering improvements visible.
- AI Coding Is Probabilistic. Your Delivery Process Should Not Be. — Why fast code generation still needs dependable verification.
