Full-Stack Solutions Engineer & Software Architect specializing in fault-tolerant web architectures, high-throughput automation engines, and distributed systems. I transform operational maturity and technical rigor into software that solves expensive business bottlenecks, cuts operational overhead, and delivers immediate ROI.
- 🏢 Enterprise SaaS & Tailored Cloud Platforms: End-to-end B2B infrastructure using Next.js 16/React 19, TypeScript, and PostgreSQL hardened with strict Row Level Security (RLS) and RBAC tenant isolation (e.g., ExePaginasWeb, SportManager PlayHub, and MultiTiendas).
- ⚡ High-Throughput Automation & AI Pipelines: Low-level and batch processing engines in C++ and Python (OwlEyeEngine), cutting manual data review workloads from ~5 hours to unattended minutes with applied AI models.
- 📐 Rigorous Formal Verification & CAS Engines: Symbolic computation and axiomatic verification architectures (Polymath Zero) using Astro 5, React 19, strict TypeScript, and KaTeX math kernels.
- 📉 Traceability & Error Eradication: Production tracking pipelines that eliminated critical inventory discrepancies and reduced reconciliation errors by 35%.
- 🛡️ Cyberdefense & Networking Observability: Kernel-level systems monitoring, real-time audit journals, Cisco-certified networking (CCNA Basics - Score 86/100, 2026), and heuristic threat detection.
- 🚀 Sovereign Architectural Ownership: Pure proprietary codebases across +30 auditable GitHub repositories, granting zero vendor lock-in and deterministic execution.
