Senior Full Stack Developer
About Me
I am a Senior Full Stack Developer with 17 years of experience building production systems that connect language models, third-party APIs, and user-facing web applications. My recent work has focused on AI-native development, including wiring LLM reasoning into real-world integrations, orchestrating multi-step workflows, and shipping quickly with modern JavaScript and Node.js.
I have a strong track record of integrating multiple SDKs and external services quickly, and I adapt to new tools and frameworks within days. My core strengths include full stack JavaScript, backend development, data handling, AI automation, and deep third-party API integration.
In recent roles, I have built unified integration layers, automated ATS systems, Slack bots, onboarding flows, and operational dashboards. I have also worked on legal-system data extraction, telephony integrations, backup automation, and ERP development for inventory, purchasing, logistics, and restocking workflows.
My experience spans remote consulting, freelance development, and long-term enterprise systems work. I have contributed as a principal developer, project lead, IT consultant, and senior developer across companies in the United States and Colombia.
I am comfortable working across Node.js, JavaScript, React, Python, PHP/Laravel, MySQL, SQL Server, REST, GraphQL, microservices, Docker, Git, CI/CD, and automation platforms such as Zapier and Make. I am also actively adopting TypeScript, Next.js, LangGraph, LangFuse, GCP, and BigQuery.
I bring a practical, delivery-focused mindset and enjoy building systems that reduce manual work, improve operational efficiency, and connect business processes through reliable software and automation.
