About Carlos
I architect and deploy resilient, event-driven data systems and orchestrate large-scale Artificial Intelligence solutions for enterprise and B2B clients. With a strong track record of engineering production-grade SaaS platforms, my core focus is bridging the gap between raw LLM capabilities and scalable cloud infrastructure.
As the Principal Architect behind systems like 'Nexa Hub', my technical domains include:
High-Performance Data Engineering: Web scraping and OSINT infrastructure, specializing in overcoming strict bot-detection (Cloudflare, Datadome) using Playwright and stealth protocols.
Serverless Cloud Architecture: End-to-end development utilizing Node.js, Next.js, and Supabase / PostgreSQL.
Real-Time AI Orchestration: Integrating multi-model LLMs (Claude 3.5, GPT-4) via Server-Sent Events (SSE) and asynchronous worker queues (BullMQ).
I operate on an 'Async-First' methodology. I partner with CTOs and founders not just to write code, but to deliver scalable, fault-tolerant, and GDPR-compliant technical foundations with zero need for micromanagement.
