Summary
🤩
Rockstar🎓
Top SchoolJavier Martinez is an AI Solutions Architect and full-stack engineer with 10 years of experience building production-grade, resilient AI systems from prototype to scale. Based in Oviedo, Spain, he designs provider-agnostic end-to-end architectures (Hexagonal) and has engineered high-performance hybrid RAG search, semantic model routing, distributed circuit-breakers, and self-correcting learning loops for real-world deployments. He couples strong DevOps and FinOps sensibilities—CI/CD, mutation testing, and SOC2-minded PII scrubbing—with hands-on implementation, contributing across frontend and backend code (notably to a private-GPT project integrating Ollama/Hugging Face models and summarization features). Previously he founded and scaled EdTech products with data-driven growth and automation, and earlier roles cover RPA-driven logistics automation and full-stack .NET/web development. Known for pragmatic architectural rigor, he blends deep systems thinking with an appetite for refining ML systems in production.
