You will get a custom AI SaaS platform using Next.js and Google Gemini API
Project details
Are you tired of basic AI wrappers and clunky ChatGPT bots? You need a real, production-ready AI Architect.
You will get a custom, high-performance AI SaaS web application built with Next.js, Node.js, and the Google Gemini API (or OpenAI). I specialize in building real-time AI solutions, from automated workflow agents to RAG (Retrieval-Augmented Generation) pipelines that actually understand your business data.
What sets me apart? I am not just a frontend coder; I am a Full-Stack AI & DevOps Engineer. I don't just build the UI; I architect the entire data pipeline and ensure it is deployed securely. My flagship work includes building real-time voice-transcription AI sales co-pilots with sub-3-second latency.
What you can expect: • Modern Frontend: Next.js & React for a blazing-fast, premium UI (Glassmorphism, Dark mode). • Powerful AI Backend: Node.js integration with LLMs, custom prompts, and RAG architectures. • Security & DevOps: Secure API key management, database integration, and optional Linux VPS deployment (NGINX, PM2).
Let's build an AI product that your users will actually want to pay for. Send me a message before ordering so we can discuss your architecture!

About Ernesto
Full-Stack AI SaaS Developer | Architect/Agent builder | n8n/GHL Autom
Soacha, Colombia - 12:33 pm local time
My flagship project: WINGMAN — a real-time AI sales co-pilot that captures live phone audio via Web Speech API, processes it through Google Gemini with RAG pipelines, and projects neuromarketing tactics on-screen as a teleprompter. Built with Next.js 16, TypeScript, React 19, Node.js, and deployed on hardened Linux VPS with NGINX, PM2, and SSL.
What I deliver: • Full-stack AI applications (voice, chat, RAG, real-time processing) • VPS infrastructure — deployment, security audits, NGINX, PM2, Fail2Ban • CRM integrations — GoHighLevel, OAuth2, automated email campaigns • Google Ads management with click fraud detection scripts • WordPress/Elementor sites with SEO and local directory automation
I work fast, communicate clearly, and ship production-ready code. English and Spanish fluent. Based in the US, available across time zones.
Beyond AI, I deliver full-cycle digital products: • Real-time voice AI apps (Web Speech API, WebSocket, Gemini/OpenAI) • Linux VPS administration with military-grade security audits • CRM API integrations (GoHighLevel, OAuth2, workflow automation) • Google Ads campaigns with Python-based click fraud forensics • WordPress sites, landing pages, and local SEO across 50+ directories
I write clean, documented, production-ready code in JavaScript, TypeScript, Python, and PHP. Fluent in English and Spanish. US-based, responsive, and deadline-driven.
