Senior software engineer and CTO shipping things end to end — from Rust engines and Go backends to native SwiftUI apps and SvelteKit on the edge. I care about speed, correctness, and shipping.
selected work
Not demos. Real engines, real apps, real users — each one taken from an empty repo to something running.
Realtime news intelligence
A realtime RSS ingestion engine that watches hundreds of sources, deduplicates the noise, and ranks the stories that actually matter — with entity extraction and AI summaries so you read the signal, not the feed.
Zero-knowledge Mac backups
A Time Machine alternative built from scratch in Rust: content-defined chunking, BLAKE3-addressed dedup, and encrypted, versioned snapshots pushed to S3-compatible storage. Browse and restore any version from a browser tab — decryption stays in-tab, so the server never sees your files.
Fast macOS disk cleaner
Reclaim every byte. A fast macOS disk cleaner with a Rust scanning engine and a native SwiftUI app — it finds dev caches, build artifacts, and forgotten junk, shows every path before it touches anything, and moves files to Trash first. Nothing leaves your machine.
Zero-latency camera streaming
Camera streaming that starts the instant you press play. Built on go2rtc, my fork adds keyframe caching, a ring-buffer time-shift, and RTP sequence rewriting so WebRTC playback never waits for the next I-frame — first frame is already there.
Bible study, reimagined
A full-stack Bible study app: a native SwiftUI iOS client with offline reading, audio playback, AI chat, and cross-device sync, backed by a TypeScript/Bun API and a SvelteKit marketing site. Shipped end to end — app, backend, and infra.
the toolkit
I pick the tool that fits the job — systems work in Rust and Go, native UI in SwiftUI, product on SvelteKit. The constant is shipping something solid.
about
I'm Francisco — a senior software engineer and CTO who likes owning a problem from the metal up to the pixels. I care about software that's fast and correct, and about teams that actually ship.
Lately that's meant content-addressed backup engines in Rust, realtime ingestion pipelines in Go, native macOS and iOS apps in Swift, and slick frontends on SvelteKit + Cloudflare. If it's hard and worth doing well, I'm in.
