Juan Pablo G.
Senior AI & Systems Engineer | AI Safety & Backend Architect
“Engineering Certainty in an Uncertain World.” I am a Senior AI & Systems Engineer with 15+ years of experience building, securing and supporting production software, cloud infrastructure and high-reliability backend systems. As the founder of SolidScripts, I help companies turn complex technical problems, legacy systems and uncertain AI workflows into maintainable, production-ready solutions. My strongest areas include: • AI systems: LangGraph, RAG, Claude/OpenAI integrations, MCP, tool calling, agent workflows, evaluation and security guardrails. • Secure automation: human approval gates, structured tools, audit trails, idempotency, retries and failure-safe execution. • Backend engineering: PHP/Laravel, Python, TypeScript, Node.js, SQL and REST API integrations. • Cloud and infrastructure: AWS, Azure, Linux, Docker, deployment, monitoring, hardening and incident response. • Healthcare and sensitive-data systems: EMR/EHR workflows, controlled AI access, session integrity and privacy-conscious architecture. • Technical audits: evidence-based reviews, risk classification and prioritized remediation plans. I have supported production systems and urgent incidents for more than a decade, with a calm, methodical approach to troubleshooting and root-cause analysis. I personally review and test AI-assisted code rather than treating generated output as production-ready. Clients hire me when reliability, security and technical ownership matter. I can contribute as a senior individual engineer, technical lead or architecture and security partner. Let’s build something solid.
