👨‍💻 About Me

Junior full-stack developer who builds complete products: web and mobile front ends, .NET and Node.js backends, databases, deployment, and AI features that solve a real problem. My projects are live and documented, from a website builder that generates sites from one sentence to a microservice system that keeps an AI agent from approving payments on its own.

🚀 Featured Projects

AI-assisted invoice approval system. An AI agent scores invoices against company expense policy; a deterministic router enforces amount ceilings and fraud rules, then auto-approves, escalates, or rejects. .NET 9 microservices on Dapr with a YARP gateway and saga-based payment compensation. 20/20 routing accuracy on labelled invoices with zero false approvals.

C# / .NET 9 Dapr Blazor Docker

Mobile plant-care app. Photograph a plant and Plant.id identifies the species, diagnoses diseases and pests with treatment advice, and writes a care guide; the app plans watering, sends reminders and keeps a growth journal with stats. React Native (Expo SDK 57) over a .NET 9 REST API with JWT auth, EF Core migrations and PostgreSQL on Neon.

🏗️ DragCanvas

AI website builder: describe a site in one sentence, the AI lays it out with real stock media, then refine it in a Craft.js drag-and-drop editor and publish it live to Netlify. Contact forms, per-site analytics, email notifications and an admin area with charts from a Python reports service. Live demo
