Harison K.
Full-Stack Web & Android Developer | WordPress, GHL & Apps
I build fast, scalable websites, native Android applications and high-converting business automations that run reliably long after launch. If you are looking for an experienced developer who handles everything from pixel-perfect Figma designs to complex back-end integrations, I can help. What I Do Best: 1. WordPress & Web Development - Pixel-perfect Figma-to-WordPress conversions using Elementor, Divi or custom themes. - Platform setups for LMS (Moodle), e-commerce (Shopify, WooCommerce) and CMS (Framer, SquareSpace & Webflow). - Speed optimization, mobile responsiveness, and clean, manageable backend architectures. 2. Native Android App Development - Modern native Android builds powered by Kotlin. - Room Database for offline caching and Firestore for real-time synchronization. - On-device Machine Learning integration using TensorFlow Lite. 3. Automations, CRM & Payment Gateways - GoHighLevel (GHL) CRM setups, automated messaging workflows and sales funnels. - Seamless payment gateway integrations: Stripe, PayPal, PesaPal, and M-Pesa (Daraja API). 4. SEO & Technical Performance - Google Business Profile (GBP) optimization and speed audits. - On-page SEO, clean site structure and technical performance fixes. Clients enjoy working with me because I prioritize clear, proactive communication and maintain flexible time-zone availability to keep projects running smoothly. To ensure you or your team feel fully confident managing the platform after launch, I provide a custom video walkthrough covering every detail of your system. Plus, to give you complete peace of mind, every project comes with a 3-month post-launch warranty that covers any bugs or necessary adjustments free of charge.
