Full-stack developer & product builder — from AI-powered SaaS to online game servers, automation, growth/SEO and audio DSP.
I take ideas from concept to deploy: architecture, code, security and shipping.

• 🌐 Full-stack web — React + TypeScript SPAs (Vite, Tailwind), Node/JS & Python (Flask) back-ends, integrating Supabase (PostgreSQL + RLS + Deno Edge Functions) and Firebase (Auth + Firestore).
• 🤖 AI integration — multi-provider LLM gateways (Gemini, OpenAI, Groq, OpenRouter, Claude), content generation, prompt/persona systems and text-to-speech (TTS).
• 📈 SEO / GEO & growth — technical audit engines (Lighthouse, Schema, E-E-A-T, GEO for AIs), lead generation, data scraping/enrichment and cold-email automation.
• 🎮 Game dev — online MMO server & client in Lua: game systems, networking, scripting, GLSL shaders and Windows installers (NSIS).
• ⚙️ Automation & scripting — Python, AutoHotkey, PowerShell and scripting for Adobe After Effects & Photoshop (video/image production pipelines).
• 🛒 E-commerce / CMS — WordPress / WooCommerce themes & stores (PHP/Twig).
• 🎧 Audio & DSP — high-fidelity synthesis (Solfeggio frequencies, binaural beats, colored noise at 96kHz/32-bit float).
• 🔐 Applied security — server-side encrypted secrets, multi-tenant RLS, API proxies and sensitive-data redaction.

• AI-powered SEO + GEO SaaS (private) — full technical site auditing, multi-provider AI content generation, local/programmatic SEO, ranking analysis and cold email. Plan-based RBAC, multi-tenant isolation (RLS) and server-side encrypted API keys.
• Online MMO — server + client (private) — large-scale Lua project with game systems, client/server networking, shaders and Windows packaging.
• Prospecting automation engine (private) — back-end orchestrating campaigns and sends for a cold-email ecosystem.
• WordPress/WooCommerce store (private) — complete theme and e-commerce for a live shop.
• SEO Lead Hunter — automated lead generation: Google Maps discovery, enrichment (Hunter.io/Apollo + scraping), Reddit opportunities and HTML reports.
• Nexus Audio Lab — high-fidelity audio synthesis (Solfeggio, binaural, colored noise) at 96kHz/32-bit float.
• Open Voice Studio — Gradio panel to generate MP3 narrations with TTS and reference voices.
• After Effects automation panel — ScriptUI for automated video compositions.
• Interactive game guides (PT-BR) — static site with calculators and an interactive map.
• ...plus various automation utilities (video downloading, batch renaming, clipboard capture).

Open to collaborations in web, AI, automation and digital products.
