Vasco Smith

compilers · Rust, SSA IR

• · Building a generic, sample-agnostic JavaScript deobfuscator on a custom SSA-based IR with memory SSA and side-effect tracking.
• · Shipped a six-stage pipeline (parse → normalize → control-flow recovery → decode → dataflow + DCE → rename) that runs to fixpoint.
• · Published the devirt-corpus dataset on Hugging Face (~9.5k rows, ~2.4k downloads) for benchmarking against real obfuscators.

internship search · TypeScript, Cloudflare Workers

• · Built easystage.nl end to end, an internship-search platform for Dutch students spanning scraper, API, and dashboard.
• · Wrote a TypeScript Cloudflare Workers scraper that ingests stagemarkt.nl listings into D1 and republishes them through a public API.
• · Shipped a React/Vite dashboard with search and filtering, plus Discord notifications for new listings.

proxy infrastructure · Rust, Go, Redis

• · Rewrote the proxy pool collector from Go to Rust after the Go version leaked memory under long-lived load.
• · Maintained geo-indexed snapshots tracking ~140k proxies across ~133k unique outbound IPs, backed by Redis health checks and duplicate detection.
• · Refreshed pools from upstream providers (Oxylabs and similar) and exposed per-country selection to the public API.
• · Triaged and patched the original Go collector pre-rewrite to keep the service running during migration.
