Section 01 //About

Computer Science student and developer focused on AI-driven automation. Hands-on experience shipping local AI/voice tools in Python, a programming-language interpreter in C#, and live web applications. As the sole technical owner at ReAgent Realty Brokerage, I built and deployed the company's full production web platform (Next.js + Supabase) in one month. I work fluently with Claude Code, authoring custom agent skills and multi-agent workflows that sharply multiply my delivery speed.

AI & Automation

  • Local AI/voice systems in Python: speech-to-text, wake word, VAD, streaming TTS.
  • Claude Code power user — custom agent skills and multi-agent workflows.
  • Programming-language interpreter in C# (lexer, parser, semantic analysis).
  • Automation pipelines that remove manual steps and ship faster.

Production Web Engineering

  • Full-stack Next.js 14 + TypeScript + Supabase, zero to production.
  • Security hardening: CSP, XSS sanitization, rate limiting, CAPTCHA.
  • Technical SEO, EN/ES/PT internationalization, accessibility.
  • Testing & CI/CD: Vitest, Playwright, GitHub Actions, Vercel.

Experience

Founding Software Engineer (Sole Developer) · ReAgent Realty Brokerage

Apr 2026 — Present

Remote

Sole technical owner of a Miami-focused luxury real-estate startup — the first Bitcoin/blockchain-based brokerage in Miami Beach.

  • Built and shipped the company's production web platform single-handedly — Next.js 14 + TypeScript + Supabase, deployed on Vercel — from zero to production in one month.
  • Engineered a secure Supabase backend (Postgres, Row-Level Security, role-segregated clients) and hardened the app via a self-run security audit: nonce-based CSP, XSS sanitization, IP rate-limiting + CAPTCHA on the leads API.
  • Implemented technical SEO (schema.org JSON-LD, hreflang, sitemap) and EN/ES/PT internationalization, plus validated lead-capture forms (Zod + react-hook-form).
  • Set up the full quality pipeline: Vitest unit tests, Playwright E2E with local Supabase, GitHub Actions CI/CD, and Vercel observability.
  • Multiplied delivery speed by mastering Claude Code: authored 14 custom skills and a multi-agent (review/test/research) workflow that automate releases and QA.

Freelance Web Developer · Real Estate Landing Pages

2025 — Present

Remote

Independent web work for real-estate lead generation.

  • Built and operate an automated HTML redirect system serving time-windowed landing-page previews for property listings via Cloudflare tunnels.
  • Designed the automation so lead-facing previews update without manual intervention and degrade gracefully outside viewing hours.
