🎁 Free Architecture Mini-Consultation Tell me what you want to automate — WhatsApp, voice/phone, documents, internal ops — and I'll send you an architecture sketch, the quick wins, and cost options. No cost, no commitment. 🧠 What I Do I design and scale cloud-native systems on AWS and build Generative AI solutions (LLM agents, RAG, copilots) that plug into real operations — the agents I run today serve 20,000+ users in production. My focus: business impact in weeks, from Idea → MVP → PMF, with security, observability and cost efficiency at every stage. 🚀 What I Build (in weeks, not months) 🤖 LLM agents, copilots and RAG with vector databases — trustworthy answers with source citations 🎙️ Voice AI that answers phones, intercoms and front desks — real-time, English/Spanish 💬 WhatsApp agents for bookings, payments, support and FAQs — my last deployment took over ~80% of the team's repetitive work ⚙️ Enterprise automations across sales, support, ops and documents (extraction, classification, scoring) 🧩 Third-party integrations: ERP/CRM, hotel PMS, payments, BI, telephony, messaging 🔒 Security, monitoring, human-in-the-loop guardrails and cost optimization out of the box ☁️ Cloud-native on AWS (Bedrock AgentCore, Lambda, ECS) and Supabase — serverless by default 🧭 How We'll Work (Idea → MVP → PMF) 1️⃣ Discovery (free) — goals, quick wins, architecture sketch, and a prioritized backlog 2️⃣ MVP Sprint — a working system with clear metrics and guardrails, demoed weekly in English 3️⃣ PMF & Scale — hardening, SLOs, advanced automations, cost optimization, and documentation your team can run without me 🏷️ Brands I've Worked With 🚗 Toyota – Kinto Share — WhatsApp agent for the end-to-end car-rental booking journey 🏨 Casa Andina Hotels — WhatsApp concierge proof-of-concept + adoption consulting for their in-house team 🏨 BTH Hotel — pilots and operational automations with conversational AI ⛏️ OPERMIN (mining) — voice-AI interview system that cut accident investigations from 3 months to 10 days 📄 Bureau Veritas & La Tinka — document AI: extraction, classification and 0–100 scoring 🏢 Portero Seguro — CTO & Co-Founder: the AI Doorman — voice intercom + WhatsApp agent, 20,000+ residents, 85% of requests resolved without a human 🎛️ Leadership & Direction (CTO / Architecture) I operate as a hands-on CTO and cloud architect: I define the architecture, write the production code myself, orchestrate cross-functional teams and vendors, and keep product, data and engineering in one tight loop — from idea to PMF. 🧩 Tech Stack 🤖 LLMs & Evaluation — OpenAI, Claude, AWS Bedrock (AgentCore), Strands Agents, LangChain / LangGraph, LLM-as-judge evals, vector DBs (pgvector) 🗣️ Voice AI — LiveKit, Deepgram, ElevenLabs, Vapi (inbound/outbound, IVR, intercoms) ⚙️ Automation & Orchestration — WhatsApp Business API, n8n, Make, Botpress 🗄️ Data & Back-End — PostgreSQL, Supabase, Node.js, NestJS, Python, FastAPI ☁️ Cloud — AWS (Lambda, ECS, API Gateway, Cognito, S3), Terraform, serverless by default 📱 Front & Mobile — React, Next.js, React Native 🔌 Integrations — ERP/CRM, hotel PMS, payments, BI, telephony, webhooks 📌 Plus — Quant Background Before doubling down on generative AI, I delivered 20+ trading-automation solutions on this very profile (Binance, Bybit, MT4/5, NinjaTrader, Interactive Brokers). That quantitative discipline — measure everything, automate everything — is baked into how I build enterprise systems today. It's also where my 100% Job Success comes from. 📣 Call to Action Message me with the process you want automated and I'll send your free mini-roadmap: architecture sketch, integration plan, cost/risk map, and the first two quick wins.
