Job Success

Do you need a production-ready web app, a Shopify store that goes beyond what off-the-shelf apps can do, or a business process that's still eating up hours it shouldn't? I build the full stack behind all three — and connect them with AI automation so your systems don't just run, they run themselves.
I'm a Full Stack Developer with 𝟒+ 𝐲𝐞𝐚𝐫𝐬 of experience helping startups, agencies, and business owners ship SaaS platforms, Shopify stores, and custom APIs — and increasingly, AI-powered automation that removes manual work from all of them. Whether it's a customer support chatbot, an automated order/inventory workflow, or an internal tool that used to take a spreadsheet and three people, I build it once, connect it properly, and keep it running after launch.
My approach: solve the actual business problem with the smallest, most maintainable solution — not the most impressive one. That's why clients keep me on past the first project.
