José Andrés M.
Systems Engineer | Full-Stack & AI Developer | Backend Specialist
I am a Systems Engineer focused on building scalable full-stack solutions and AI-powered applications. My approach combines rigorous engineering principles with a deep understanding of modern web architectures, distributed systems, and LLM integrations (OpenAI, Claude, RAG workflow automation) With a "Linux-first" mindset, I manage my development environment entirely through terminal-driven workflows (Debian/Kali), giving me full control over system configurations, secure automation scripts, and server-side troubleshooting. What I bring to the table: • Full-Stack & AI Integration: Experienced in building production-ready applications combining modern frontends (React/Next.js) with powerful backends (FastAPI/Node.js) and seamless AI/LLM integration (OpenAI, Claude, RAG, and automation workflows). • Backend & Architecture Expertise: Developing high-performance, security-aware RESTful APIs, implementing clean architectures, and maximizing system reliability. • Versatile Data Management: Strong hands-on experience designing and optimizing database schemas in both SQL and NoSQL environments, specializing in PostgreSQL, Supabase (with strict Row-Level Security), and Firebase. • Systems & Automation: A "Linux-first" developer skilled in Python and Go for scripting, infrastructure automation, CLI/TUI tool development, and secure secrets management. • Technical Documentation & DX: Expert in creating professional, highly detailed technical documentation and interactive READMEs using Markdown, ensuring seamless remote onboarding and maintainable codebases. • Adaptability & Remote Mindset: Proven track record in fast-paced environments (startups like DocIA and companies like Paramo Games), delivering clean, scalable code that aligns with real business goals across distributed time zones.
