AI agent systems that work in production, not just in demos. That's what I build, and that's what I've delivered across platforms serving 40,000+ users, 120+ businesses, and $1B+ in transactions. As an AI agent and automation systems engineer, I design and build Python-based, LLM-powered systems that automate workflows, support decision-making, and integrate into existing products and operations. My focus is on building production-ready systems that are reliable, maintainable, and ready for real-world use from day one. What I built: 1. AI agent and multi-agent systems using LangGraph, LangChain, and Claude/OpenAI APIs. 2. RAG pipelines with vector databases (Pinecone, Qdrant, ChromaDB) for document intelligence and knowledge retrieval. 3. Workflow automation and API integration connecting CRMs, SaaS tools, and internal systems into end-to-end automated pipelines. 4. AI chatbot and conversational AI platforms with real-time retrieval and structured outputs. 5. Full-stack AI platforms from database to deployment (Python, FastAPI, React, Next.js, Node.js). 6. Document processing and NLP pipelines for extraction, classification, and compliance. How I work: I start by understanding the problem and defining the system before writing code. From there, I build a working proof of concept and evolve it into a production-ready solution. I pay close attention to system design, stability, and extensibility so that what I deliver can be confidently used and owned by your team. My approach is practical and outcome-focused. I choose tools based on what best serves the system: whether that's a LangGraph state machine for agentic AI orchestration, a FastAPI microservice for backend logic, an n8n workflow for automation, or a React frontend for the user experience. I pick what fits the problem rather than following trends. Skills: AI Agent Development, AI Automation, Python, LLM Integration (OpenAI, Claude/Anthropic), RAG Systems, LangGraph, LangChain, Prompt Engineering, Vector Databases (Pinecone, Qdrant, ChromaDB), Chatbot Development, NLP, Machine Learning, API Integration, FastAPI, React, Next.js, Node.js, Supabase, AWS, Google Cloud, n8n, React Native, Generative AI, Document Processing, Data Pipelines Clients reach out when they need more than a trained model or a chatbot wrapper. They need an AI agent system that works in practice, fits into their product or workflow, and delivers measurable outcomes. If you are planning to build an AI agent, a RAG system, a workflow automation, or a production-ready AI solution, send me a message with your use case. I am happy to review your requirements and suggest the right approach before you commit.

I help businesses build AI-powered SaaS products, internal tools, automation systems, and RAG applications using Python, JavaScript, and modern full-stack frameworks. I’m a Top Rated Full Stack Developer with $150K+ earned, bringing strong experience across React.js, Next.js, Vue/Nuxt, Node.js, Python, FastAPI, Django, OpenAI, Claude, RAG systems, and production SaaS development. My background started in full-stack product development, building SaaS platforms, dashboards, APIs, CRM tools, and frontend applications. Over time, I moved deeper into Python, AI integrations, document search, automation workflows, and AI-Native development using tools like Claude Code, Cursor, GitHub Copilot, and ChatGPT. Most of my work sits between AI engineering and full-stack product development. I build systems that can search documents, answer questions, automate follow-ups, update CRMs, connect third-party APIs, process data, and give teams clean dashboards to manage everything from one place. What I can help with: Python backend development using FastAPI, Django, Flask, APIs, scripts, data processing, and integrations JavaScript/TypeScript development using React, Next.js, Vue/Nuxt, Node.js, and modern frontend/backend tools AI integrations using OpenAI, Claude, GPT APIs, assistants, structured outputs, and tool/function calling RAG systems, AI search, document Q&A, internal copilots, and knowledge-base assistants Full-stack SaaS platforms, admin dashboards, internal tools, API integrations, deployment, and production support AI-assisted development using Claude Code, Cursor, GitHub Copilot, and modern coding agents to move faster while keeping code clean and maintainable Relevant work: I worked on Neblo.AI, an AI-powered freight automation platform for brokers. The system handled AI-driven lead qualification, carrier matching, automated communication workflows, and operational automation to reduce manual calls, inbox overload, and follow-ups. I also built a RAG-based mortgage guideline platform where users could search complex documents, ask scenario-based questions, and receive structured answers grounded in source content. If you need a developer who can combine Python backend engineering, JavaScript full-stack development, and practical AI integration, I can help you build a product that is clean, scalable, and useful in the real world.

I am a computer engineer and AI-focused backend developer with more than a decade of experience in education, research, and real-world system building. Since 2013, I have worked as a professor at Universidad Técnica del Norte, where I have taught computer engineering and helped grow many highly capable engineers now working in industry. Alongside teaching, I have continuously expanded my expertise in challenging areas such as artificial intelligence, machine learning, and large-scale system design, building a strong and practical technical foundation. My work sits at the intersection of AI, backend engineering, automation, and data. I help teams take unclear ideas, raw data, or manual workflows and turn them into clean, reliable, production-ready systems that work day to day. On the AI side, I focus on practical LLM applications rather than demos. This includes RAG pipelines, multi-agent systems, chatbots with memory, document processing, semantic search, classification, extraction, and automation workflows. I have hands-on experience with LangChain, Hugging Face, OpenAI, Claude, and vector databases such as Pinecone and FAISS, including fine-tuning when it makes sense. My priority is always usefulness, reliability, and maintainability. Backend engineering is a core strength. I design and build APIs, services, and data pipelines using Python with FastAPI, Flask, and Django. I care deeply about clean architecture, performance, and systems that are easy to extend and maintain over the long term. I also have a strong background in automation and data engineering. I have built web scrapers, crawlers, ETL pipelines, data cleaning systems, reporting tools, dashboards, and bots for years. My focus is on stability and resilience, not fragile scripts that break after a short time. Deployment and infrastructure are part of my workflow, not an afterthought. I regularly deploy and operate systems on AWS, GCP, and Azure, using Docker, CI/CD pipelines, and serverless or containerized architectures depending on the project’s needs. I have worked with universities, companies, startups, and individual founders, often acting as a technical partner rather than just a task-based freelancer. I take time to understand the business goal first, then design a technical solution that fits it. I joined Upwork in 2016 out of interest and haveused the platform just to enjoy my creative hobby projects such as design and visual work, not for my major. But always, I couldn't spare time for it. Over the years, I closely followed the platform’s growth and always wanted to collaborate with global clients. I recently retired from my academic-related work and can now dedicate myself to professional freelance activities. What you can expect when working with me: - production-ready AI and backend systems - clear communication and realistic estimates - strong ownership and responsibility - solutions designed to scale and last If you are looking for someone who can combine AI, backend engineering, automation, and data into one solid, dependable system, I would be glad to work with you.
