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.

Verified by reading `convex-backend`'s Rust isolate. - [get-convex/better-auth](https://github.com/get-convex/better-auth/pulls?q=is%3Apr+author%3Aramonclaudio+is%3Amerged): 5 merged PRs including [#323](https://github.com/get-convex/better-auth/pull/323) (breaking migration to better-auth 1.6, five runtime breaks in one rebase), [#218](https://github.com/get-convex/better-auth/pull/218) (stale credentials after session expiry), and [#267](https://github.com/get-convex/better-auth/pull/267) (`fetchAccessToken` deduplication). - [expo/expo#46714](https://github.com/expo/expo/pull/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](https://github.com/withastro/compiler-rs/pull/25) + [napi-rs/napi-rs#3189](https://github.com/napi-rs/napi-rs/pull/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](https://github.com/expo/expo/pull/45872): `` 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](https://github.com/expo/expo/pulls?q=is%3Apr+author%3Aramonclaudio+is%3Amerged): 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](https://github.com/shadcn-ui/ui/pulls?q=is%3Apr+author%3Aramonclaudio+is%3Amerged): 5 merged PRs including [#10396](https://github.com/shadcn-ui/ui/pull/10396) (TanStack Start dark mode guide, replacing 4 prior attempts), [#9484](https://github.com/shadcn-ui/ui/pull/9484) (ComponentsList Copy-Page fix), and [#10337](https://github.com/shadcn-ui/ui/pull/10337) (llms.txt audit of 97 URLs). ## Projects - **[convex-revenuecat](https://github.com/ramonclaudio/convex-revenuecat)**: Convex component mirroring RevenueCat subscription state.
