Cristhian E.

I build intelligent, scalable, and well-architected software systems that solve real business problems. I’m a full-stack engineer with strong expertise in backend architecture, automation systems, AI integration, and computer vision. I don’t just write code — I design solutions that are reliable, maintainable, and production-ready. What I Do! Backend Development: - REST APIs with Python (FastAPI, Django) - Scalable system design - Data modeling and SQL/NoSQL databases - Authentication, rate limiting, and secure API architecture - Payment data processing (including structured financial formats like ISO-style transformations) Frontend Development: - Clean, responsive UI development - Admin dashboards and internal tools - UX-focused design for SaaS products - Integration with backend APIs Automation Systems (with and without AI): - Workflow automation (n8n-style architectures) - API integrations between multiple services - Data pipelines and structured transformations - Task automation for operations and business processes - Deduplication logic, state-based processing systems, and event-driven workflows Applied AI Engineering - LLM integrations (RAG systems, intelligent agents, structured outputs) - AI-powered claim/document analysis systems - Prompt architecture and evaluation pipelines - AI-powered SaaS feature design - Automated decision-support systems Computer Vision: - OpenCV-based processing pipelines - YOLO object detection systems - Image classification and preprocessing - Real-time detection and automation workflows based on visual input How I Work: I think in systems, not scripts. I prioritize clean architecture and long-term scalability. I design with production in mind (logging, monitoring, validation, edge cases). I communicate clearly and focus on measurable outcomes. Whether it’s building an AI-powered claims analysis platform, a fintech MVP backend, a computer vision pipeline, or a custom automation system — I aim to deliver solutions that are robust, understandable, and easy to extend. If you're looking for someone who combines engineering depth, automation thinking, and practical AI implementation — I’d be happy to collaborate.
