Daian G.

I'm a Senior Automation Engineer and Backend Software Engineer with 15+ years of experience designing scalable backend systems, AI-powered automation, and data pipelines that turn manual work into reliable, self-running processes. I build automation both ways: no-code/low-code workflows (n8n, Make, Zapier) for speed, and custom code-based automation — AI agents orchestrated with LangChain and LangGraph, powered by OpenAI and Claude — when the workflow needs complex logic, state, or conditional decision-making that no-code tools can't handle. I've architected production systems supporting projects for U.S. government contractors, processing millions of SMS and email communications every month, integrating AI services, CRMs, contact centers, and government verification systems while maintaining enterprise-grade reliability and scalability. I've also built ETL pipelines and marketing/enrollment reporting that gave leadership teams clear, data-driven visibility into campaign performance — directly supporting decisions behind significant increases in sales and enrollments. My strength is understanding the business problem first, then choosing the right solution — whether that's a no-code workflow, a custom AI agent, an ETL pipeline, or a full backend system. Areas of Expertise: ✔ Automation: n8n, Make, Zapier — workflow & process automation ✔ AI Agent Automation: LangChain, LangGraph, OpenAI, Claude & Claude Code ✔ Data Engineering: ETL pipelines, marketing/reporting dashboards, data warehousing ✔ Python, Django, Flask ✔ Node.js & TypeScript ✔ REST APIs & Microservices ✔ SQL, MySQL & Redis ✔ AWS, Linux & Nginx ✔ Twilio Voice & Messaging ✔ SendGrid email automation and deliverability ✔ ManyChat, Voiceflow ✔ CRM & Enterprise Integrations These systems automate customer engagement, AI conversations, lead qualification, messaging campaigns, contact center routing, data reporting, and enterprise workflows end to end. What I Build: ✔ AI agent automation (LangChain/LangGraph) ✔ No-code/low-code automation platforms (n8n, Make, Zapier) ✔ ETL pipelines & marketing/enrollment reporting dashboards ✔ High-performance backend systems and dashboards ✔ AI-powered applications ✔ Twilio Voice & Messaging solutions ✔ Enterprise API integrations ✔ CRM integrations ✔ Internal business tools ✔ Customer engagement platforms ✔ Conversational AI ✔ High-volume messaging systems ✔ Webhook-based architectures I'm also an active open-source developer. I've published Python packages, APIs, and applications for Twilio, ManyChat, and Voiceflow ecosystems, including integrations used by developers building conversational platforms. Why Clients Hire Me? I don't just write code or connect no-code blocks. I help businesses design automated systems — from simple workflows to AI agents to data pipelines — that reduce manual work, improve reliability, and directly support growth and revenue decisions. I enjoy taking ownership of projects from architecture through deployment, working closely with both technical and non-technical stakeholders. If you're looking for someone who can combine automation, AI agents, data engineering, and backend architecture to solve real business problems, I'd love to discuss your project.
