DocFlow AI is an enterprise document intelligence platform that transforms unstructured documents into searchable, actionable knowledge.
The platform automatically extracts information from PDFs, Word files, invoices, contracts, and reports, builds a searchable knowledge base, and enables users to interact with their documents through an AI assistant using Retrieval-Augmented Generation.
It combines OCR, structured extraction, RAG, AI agents, and workflow automation to simplify document-heavy business operations.

OCR Over the past year, I've been building cloud-native platforms, AI-powered DevOps automation, and secure AWS architectures for startups and growing businesses.
My recent work includes developing AI-assisted DevOps and Security agents using the Claude API, n8n, and AWS to automate incident investigation, CloudWatch log analysis, deployment validation, and security audits. I've also implemented LLMOps observability with Langfuse and OpenTelemetry to monitor AI workflows, prompts, latency, and execution traces.
Beyond AI, I've architected scalable AWS solutions for video streaming platforms, designed HIPAA-compliant healthcare infrastructure, modernized eCommerce platforms through BigCommerce migrations, and built CI/CD pipelines with GitHub Actions, Terraform, and Kubernetes.
I enjoy solving complex infrastructure problems by combining cloud architecture, automation, observability, and AI to improve reliability, security, and engineering productivity. My focus is always on building production-ready systems that reduce operational overhead while enabling teams to move faster with confidence.
