Converting raster images to vector graphics involves multiple processing stages, each feeding into the next. Here's how I designed an artifact-based pipeline architecture that tracks provenance, enforces type safety, and makes debugging complex transformations straightforward.

There's a moment in every sufficiently complex form where a Zod schema isn't enough. The email is valid. The password meets requirements. And yet, there's still a bot check to run, an API to hit, an error to map back to the right field. Here's what that looks like in practice.

While integrating TanStack Form with schema validation libraries like Zod, I ran into a subtle type system gap that caused validation errors to silently fail. Here's how I diagnosed the issue and built a type-safe wrapper to prevent it from happening again.

How I built a secure sandbox for running untrusted player scripts using V8 isolates, a two-layer API architecture, and runtime code generation.

When building time series charts that display percentages, you often need to fetch both numerator and denominator values for each data series. But what happens when multiple series share the same denominator? Here's how I used TanStack Query's hashKey function to deduplicate overlapping queries and map the results back to the original data structure.

After years of working with react-hook-form, I made the switch to TanStack Form and built a reusable component library around it on top of my company's existing form components. Here are the patterns I landed on for binding these components to form state, creating intelligent buttons with automated loading states, and lazy-loading fields for better performance.
