With 15+ years of development experience, I handle projects from planning through launch and ongoing maintenance. I work independently and write the code myself, so you communicate directly with the person building your product. Problems I can help you solve: • Your store is slow, difficult to use, or missing functionality. I improve Shopify and WooCommerce stores, customize themes, build apps, and connect payments, subscriptions, shipping, and fulfillment systems. I also work with Magento, BigCommerce, and PrestaShop. • You need to launch a product or improve an existing platform. I build SaaS MVPs, customer portals, dashboards, and APIs, and add features to existing applications using React, Next.js, Vue.js, Node.js, Laravel, and Python. • Your business needs an iOS or Android app. I develop mobile applications with React Native, Flutter, Swift, or Kotlin and connect them to your backend, business systems, and cloud services. • Your team spends too much time on repetitive tasks or searching for information. I build AI assistants that answer questions from your business documents, automate document processing, and connect your existing tools through APIs and workflows. • Your software has recurring bugs or is becoming difficult to maintain. I investigate failures, improve performance, resolve technical debt, and stabilize existing systems. You can hire me for a specific fix, a complete build, or ongoing development. I prioritize clear communication, maintainable code, and software that supports your daily operations. Tell me what you are building or what is not working, and I will help you define a practical next step. menos -
