I build production-grade agentic systems, Pinky and the Brain, a cloud-native Deep Agent (LangGraph.js) grounded by a custom RAG pipeline, deployed on AWS via Terraform and reachable through an IDE protocol, REST/SSE, and MCP. That work sits on top of a solid experience as a Front-End Developer and Web Architect, building proprietary front-end and UI frameworks, leading Micro Front-End and Web Components architectures, and shipping AWS-hosted (S3, Lambda, API Gateway) static deployment pipelines for large-scale applications. I'm currently focused on Agentic Systems, Retrieval-Augmented Generation, Prompt Engineering, and Anthropic Claude / LLM integration.
AI / Agents: LangChain, LangGraph.js (Deep Agents), Anthropic Claude, RAG (BM25 + vector fusion), MCP, Agent Client Protocol
Languages: TypeScript, JavaScript, HTML5, CSS3
Front-End: Angular, React, RxJS, Web Components, Micro Front-Ends, Tailwind CSS
Cloud & DevOps: AWS (Lightsail, S3, Lambda, CloudFront, API Gateway), Terraform, Docker, GitHub Actions
Let's Fail Project is my personal build-in-public initiative, a living GitHub ecosystem where I ship and document experimental software in the open, embracing fast, cheap failure as the fastest path to learning. It's the umbrella under which projects like Pinky and the Brain, patb-cli (its Zed IDE/CLI bridge), and Monday Money (a privacy-focused personal finance app) are built.
