My Story

I started as a frontend intern at InSynk Studios in 2022. I was mostly learning by doing — writing React components, figuring out Git, fixing things that broke, and slowly understanding how software actually gets built on a team. That internship turned into a full-time role, and over the next couple of years I got to work on products across AI, e-commerce, and Web3, including Petavue, ShopOS, and the Grail ecosystem.

In May 2024, I joined FlowScale AI as the sole frontend engineer. Being the only frontend person means I get to be involved in pretty much everything — deciding how things should work, building them, dealing with the messy parts, and eventually shipping them. I've worked on FlowScale Hub, a platform for ComfyUI workflow APIs, and FlowScale AI OS, a desktop app for GPU orchestration. Along the way, I've spent a lot of time working with React, TypeScript, Zustand, TanStack Query, WebSockets, and real-time systems.

I've always liked the part of frontend where something can be technically complicated underneath but still feel simple when someone uses it. That's probably what I care about most: building things that make sense, writing code I won't hate coming back to, and paying attention to the little details that make a product feel good.

What I Focus On

I believe great code is code that works, scales, and doesn't need explaining. Here's what drives my work:

Frontend Architecture & State Management

Building scalable React applications with TypeScript, focusing on component composition, proper abstraction layers, and state synchronization for real-time collaborative features.

Performance That Matters

Optimizing bundle sizes, lazy-loading routes, memoizing expensive renders, and using virtualization for large lists. Performance isn't just Lighthouse scores—it's how fast the app feels to users.

Code Quality & Developer Experience

Writing self-explanatory code with proper naming, adding unit tests for complex logic, meaningful commit messages, and building patterns that make onboarding new developers painless.

Real-Time Systems

Working with WebSockets, SSE, and optimistic updates to build interfaces where changes sync instantly across users without conflicts or race conditions.
