I build custom e-commerce websites and mobile apps from a single admin: Blazor (C#) for web + .NET MAUI for Android/iOS. Launch an MVP in 35 days with payments, inventory, push, and analytics.
Why clients hire me?
One admin for web + app → faster ops, lower cost of change
Checkout that converts: Stripe/Netopia, tax/VAT, shipping & coupons
Retention: push notifications, loyalty, in-app promos
Data you can act on: events, dashboards, product KPIs
Integrations: REST APIs, ERP/CRM, marketplaces feeds
Tech stack
Blazor (ASP.NET Core, C#), .NET MAUI (Android/iOS), EF Core, REST, SQL/Azure, CI/CD, analytics. (Microsoft: MAUI runs Android/iOS/Windows/macOS from one codebase; Blazor builds interactive web UIs in C#.)

Hi! I’m a Full-Stack Web Developer with a strong background in Business Informatics. This means I don't just write code, I understand the economic and operational goals behind your project and build software that actively drives your business forward. I specialize in creating robust B2B/B2C platforms, custom web applications, and high-converting e-commerce stores. I focus on delivering clean architecture on the backend and "kinetic precision" on the frontend, ensuring interfaces are not only highly functional but visually striking with smooth, modern interactions.
My core expertise includes:
• Front-End: React, Tailwind CSS (building modern, precise, and fully responsive UI/UX)
• Back-End & Databases: C# / .NET (ASP.NET Core), MySQL, Oracle SQL
• E-Commerce & CMS: WordPress, WooCommerce (complete store setups and customizations)
• Deployment & Infrastructure: Server configuration, API deployment, and database management
Whether you need a complex custom platform built from the ground up or a scalable WordPress store, I can handle the entire development lifecycle. Let's build something exceptional together!
