Profile Description

I'm a Full-Stack Developer, Shopify Developer, and AI Automation Specialist with hands-on experience building web applications, mobile apps, eCommerce stores, and business automation solutions. I help businesses turn ideas into reliable, scalable, and user-friendly digital products.

My expertise includes full-stack development using C#, ASP.NET Core, .NET MAUI, React, JavaScript/TypeScript, REST APIs, SQL databases, and cloud-based solutions. I have experience developing inventory systems, delivery management platforms, business dashboards, and custom internal tools that improve operational efficiency.

I also specialize in Shopify development—from building and customizing stores to product management, theme modifications, app integrations, and conversion-focused optimization. Whether you need a brand-new store or improvements to an existing one, I can deliver clean, responsive, and high-performing solutions.

Beyond development, I leverage AI and automation tools to streamline workflows, automate repetitive tasks, integrate third-party services, and improve productivity. I'm comfortable working with APIs, AI-powered tools, automation platforms, and modern development technologies.

What I can help you with:

- Full-Stack Web Development (.NET, React, JavaScript, SQL)
- Shopify Store Setup, Customization & Maintenance
- Custom API Development & System Integrations
- Mobile App Development (.NET MAUI)
- AI & Workflow Automation
- Dashboard & Admin Panel Development
- Database Design & Optimization
- Bug Fixes & Performance Improvements
- Technical Support & Ongoing Maintenance

Why clients work with me:

- Strong problem-solving skills
- Clean, maintainable, and scalable code
- Fast learner who adapts to new technologies
- Clear communication and regular project updates
- Detail-oriented with a focus on quality
- Committed to meeting deadlines

I'm always looking for long-term partnerships where I can contribute not only as a developer but also as a technical problem solver. Whether you need a dedicated developer, technical virtual assistant, Shopify expert, or AI automation specialist, I'm ready to help bring your project to the next level.
