I help e-commerce businesses fix slow stores and checkout problems, founders launch SaaS products and mobile apps, and teams reduce manual work with AI and automation. 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.
Excellent work. Fixed the refresh issue, resolved a scrolling problem caught during testing, and delivered on time with clear updates throughout. Took ownership from start to finish. Highly recommend.

Abel was a pleasure to work with on our Road Resq platform project. He demonstrated strong technical skills and consistently delivered quality work on the codebase. He was responsive, professional, and easy to collaborate with throughout the engagement. I would not hesitate to work with him again and highly recommend him for any software development project.
