Summary

Developer tools engineer in New York. Freelancing solo since 2013. I build CLIs, scaffolders, and Claude Code tooling. Give me a real bug with the time to dig and I’ll ship the fix. 60 PRs merged upstream to Expo, React Native, Convex, Bun, shadcn/ui, and others, every one came from hitting a wall in my own apps and chasing it down.

Experience

Software Engineer · Independent

2013 to Present · Brooklyn, NY

• 60 PRs merged upstream across 12 repos: expo/expo (34), shadcn-ui/ui (5), get-convex/better-auth (5), better-auth (3), hermes (3), fumadocs (2), withastro/compiler-rs (2), react-native (2), plus bun, TanStack/db, napi-rs, and App-Store-Connect-CLI. 8 more open across 6 repos including 2 in oven-sh/bun (CI YAML fix, peer-dep lockfile determinism), the hermes-engine podspec in react/react-native, and a codegen ref-type fix in microsoft/react-native-macos.
• Build and maintain convex-revenuecat (12,500+ npm downloads, listed on the Convex Components Directory), tanstack-cn (CLI scaffolder, ~1,250 downloads), create-claude (1,800+ downloads), and 7 other shipped npm packages, 22,000+ downloads across all of them.
• Maintain ramonclaudio/patches (70 patches for Bun, npm, pnpm, and Yarn) so my apps and other users ship the fix while upstream PRs are in review.
• 10,800+ GitHub contributions since Dec 2023 across 52 public repos (384 stars earned).
• 2018 to 2021 at This Is Not Art: built and maintained a custom Shopify storefront (Liquid) with anti-bot protections (velocity detection, duplicate-order blocking, URL gating) years before Shopify shipped native mitigation. Built internal tools: AR sculpture preview app, Instagram head-tracking game, inventory management, custom event registration with timeslot booking.
• 2013 to 2017 at Software Automation Services: designed and operated automation and monitoring infrastructure for the e-commerce sector, with hands-on application security research and API reverse-engineering. Shipped Python and JavaScript tooling, Chrome extensions, and related web services.

Selected merged PRs

• better-auth/better-auth#9281: ported ./instrumentation to conditional exports after Convex’s V8 isolate threw synchronously from import(). Verified by reading convex-backend’s Rust isolate.
• get-convex/better-auth: 5 merged PRs including #323 (breaking migration to better-auth 1.6, five runtime breaks in one rebase), #218 (stale credentials after session expiry), and #267 (fetchAccessToken deduplication).
• expo/expo#46714: an internal SwiftUI font pin silently dropped font, dynamicTypeSize, and resizable on @expo/ui’s Image. Rerouted through the modifier pipeline so SF Symbols scale with Dynamic Type.
• withastro/compiler-rs#25 + napi-rs/napi-rs#3189: root-caused the glibc incompatibility breaking Astro deploys on Vercel and Amazon Linux 2023: a zigbuild baseline in Astro’s Rust compiler CI and a silent --cross-compile fallthrough in @napi-rs/cli. Shipped in @astrojs/compiler-rs@0.1.8.
• expo/expo#45872: <Host modifiers={...}> was a silent no-op on iOS: Swift never declared the field the TS side forwarded. One field plus one .applyModifiers chain restored the whole modifier surface.
• expo/expo @expo/ui SwiftUI: the rest of the surface: the SwiftUI Alert component, worklet-backed scrollPosition bindings, scroll anchors and snap paging, clipShape/mask, per-axis scaleEffect, textContentType, textInputAutocapitalization, Dynamic Type font, and the accessibility modifiers, plus the canary packaging fix and a fork-safety CI sweep.
• shadcn-ui/ui: 5 merged PRs including #10396 (TanStack Start dark mode guide, replacing 4 prior attempts), #9484 (ComponentsList Copy-Page fix), and #10337 (llms.txt audit of 97 URLs).
• facebook/hermes#2047 + react/react-native#57518: fixes landed in Meta’s Hermes and React Native core through the internal codesync import: the armv7 CI job that failed on any fork not named hermes, and the TurboModule ArrayBuffer test that had never compiled on OSS main.
