Full-Stack Developer · Security-minded Engineer
Building and shipping production web platforms end to end — frontend, backend, databases, and the security work that keeps them honest.
I design and build full-stack web platforms — from the database schema up through the UI — and I care about getting the boring parts right: authentication, row-level security, input validation. Most of what's below is code running in production for real businesses, not tutorials.
Public, sanitized snapshots of production codebases I built and maintain. Each one links to a write-up of the real stack and architecture — secrets and PII are redacted, the engineering is not.
| Project | What it is | Stack |
|---|---|---|
| corredorholding-showcase | Corporate site + internal ops dashboard for an Amazon DSP last-mile logistics partner — shift scheduling, fleet fuel tracking, row-level security by role/center | Next.js 16 · Supabase · TypeScript |
| cdor.online-showcase | Monorepo for an AI chat platform: synced web app, Android/iOS mobile client, shared type-safe contracts | SvelteKit · Tauri · Rust |
| Rocky-IA-showcase | Mobile AI assistant with streaming chat, vision, image generation, and web search, backed by a serverless edge gateway | Flutter · Supabase · Deno |
| m1keOS | An x86 operating system built from scratch — preemptive multitasking, paging, a custom desktop UI, and its own scripting language (.m1ss) |
C · x86 ASM |
Sites I built and maintain solo, currently serving real traffic:
- cdor.online — the CDOR platform
- corredorholding.es — Corredor Delivery Service, Amazon DSP logistics partner
- jimcoexpress.es — Jimco Express, logistics landing page
New personal portfolio in progress, launching at m1keis-a.dev.
