Architecture That Scales.
AI That Ships.
Engineering That Delivers.
Senior Full-Stack Engineer & AI Architect. I help companies design distributed systems, build production AI features, and ship products that compound — and I mentor developers who want to level up their careers in architecture and AI. 6+ years at enterprise scale.
Trusted by teams at
Architecture + AI.
One Senior Engineer.
No Agency Overhead.
I work across the full stack — from system architecture to AI features in production. Whether it's designing a backend, building an AI copilot, or helping a team ship faster, I focus on solving the actual problem with the simplest approach that works.
The Short Version
I started coding at 12 with RPG Maker and building neural networks by 17. That curiosity turned into a career spanning enterprise architecture, AI engineering, and product development — building mass communication platforms for companies like SulAmérica and Caixa Seguradora, an IoT intelligence platform with AI copilot at Koru, and reducing a 12-month document workflow to 2 months at Zurich Santander.
Today I work with companies of all sizes — from startups to enterprises — who need someone to architect scalable systems, ship real features, and unblock their engineering teams. I also build my own products: Pocket Books (a reading platform with AI features), Cronock (a B2B2C booking SaaS), and ClaudIA (an open-source multi-agent assistant). The best engineers understand what it means to own something end-to-end.

What I Actually Do
AI Agents, RAG Pipelines & Intelligent Products
Production AI systems, not prototypes. LangGraph multi-agent architectures, RAG pipelines with vector search, AI copilots with tool-calling, recommendation engines, ML model ensembles, and structured LLM outputs.
Architecture Consulting
Designing the right architecture for your problem — not the most complex one. Monoliths when they make sense, microservices when they don't, and the pragmatic middle ground most teams actually need.

Omnichannel Communication Platform — 30+ Workflow Nodes, Git-Like Versioning
Built a SaaS platform for visual communication automation used by SulAmérica and Caixa Seguradora. Visual DAG workflow builder with 30+ node types, unique Git-like versioning system (branches, commits, PRs, approval gates), WhatsApp chatbot orchestrator, 4 template types, multi-tenant architecture with RBAC, and full observability. NestJS monolith consolidated from 20+ microservices.
Infrastructure Intelligence Platform — AI Copilot + IoT Sensor Network
Key contributor to the Resilion platform, working across multiple systems: helped build the Nexus backend (Hono + PostgreSQL/TimescaleDB), Sentinel monitoring dashboard (Next.js 15 + Mapbox + Three.js), AI Copilot (LangGraph with 15+ tools and intent classification), Ranger data collector agent, and Courier IoT gateway (protocol-agnostic FTP/SFTP/MQTT). Contributed to the design of a 6-model ML ensemble for predictive failure forecasting.
Document Processing: 12 Months → 2 Months — 6x Acceleration
Acted as business analyst on the Zurich Santander retroactive reading initiative, reengineering the document-processing workflow to reduce a projected 12-month timeline to just 2 months through strategic pipeline parallelization and infrastructure tuning.
Enterprise Integration Hub — 8 ADRs, 82 Business Rules, 8 External Systems
Authored a complete Solution Architecture Document (SAD) with 8 ADRs, catalog of 82 business rules across 7 categories, 37 detailed use cases, and a complete data model with 4 schemas. Specified integrations with 8 external systems (Alfresco ECM, Jarvis OCR, Pega BPM, CCM, Service Provider, Corporate Portal, BOD Seguros, PostgreSQL) with resilience policies (Circuit Breaker, Retry, Rate Limiting). Defined 8 Bounded Contexts using DDD tactical patterns and planned a gradual migration using Strangler Fig Pattern with canary deployments and automatic rollback.
3 AI Pipelines — Recommendations, Retrospectives & Reading Plans
Built three production AI pipelines: a two-phase LangGraph agent for reading plans (20-iteration tool-calling loops against Google Books API), a recommendation engine with recency-weighted context (GPT-4o, 7 candidates monthly), and a retrospective generator with 13 structured AI-generated text fields. All async via SQS, premium-gated, multi-language.
Integration Hub + AWS Optimization — 60% Less Manual Work, 20% Cost Reduction
Built an Integration Hub connecting sales platform orders with SAP, reducing manual work by 60% in the first phase. Implemented a new tech stack (NestJS, Next.js, React Native, Fargate). Structured the company's microservices architecture — defined when to use microservices, which services should stay monolithic, and migrated some microservices back to monoliths. Achieved a 20% cost reduction on AWS. Also built a subscription system, invoice app, automated bill extraction bot, and the Generator System for assembling solar panel kits.
Custom Frame E-commerce — Full Product from Database to Deploy
Built the full Quadroo platform from scratch — an app where customers purchase custom frames with personalized photo styles. Handled database modeling, API development, payment gateway integration, Brazilian postal service (Correios) integration, AWS deployment, and the company's inventory management system.
Engineering Philosophy
Keep it simple. I don't pick architectures because they're trendy — I pick them because they solve the problem with the least complexity possible. A well-structured monolith beats a poorly designed microservices mess every time. DDD when the domain warrants it, event-driven when you actually need decoupling, and a straightforward API when that's all you need. The same pragmatism applies to AI: structured outputs, proper error handling, real data validation. The right solution matches your constraints, not the hype cycle.

async createOrder(cmd: CreateOrderCommand) {

this.events.dispatch(new OrderCreated(order));
});

Not everything I do is for companies. I also work 1-on-1 with developers who want to grow faster — whether that's landing a senior role, transitioning into architecture, or breaking into AI engineering.
Career Acceleration
Strategic guidance to get unstuck and reach the next level. We work on positioning, interview prep, salary negotiation, and building a career path that actually matches your goals.
Technical Mentoring
Deep-dive sessions on system design, architecture patterns, and production-grade engineering. I help you think like a senior engineer — not just write code, but make decisions.
AI & ML for Engineers
Practical guidance for developers who want to add AI to their skillset. From building your first LangGraph agent to shipping RAG pipelines — real projects, not tutorials.
