I build scalable websites, web applications, mobile apps, e-commerce platforms, AI tools, client portals, and business automation systems. I hold a Master’s degree in AI and Machine Learning and combine practical development experience with a strong focus on automation, integrations, rapid prototyping, and building products that can grow with the business. My work includes WordPress, WooCommerce, Shopify, PHP, Laravel, Node.js, React, Next.js, React Native, MySQL, PostgreSQL, REST APIs, third-party integrations, Stripe, Twilio, OpenAI, CRM and ERP integrations, cloud deployment, performance optimization, security improvements, and ongoing maintenance. I have worked with startups, agencies, and established businesses to turn ideas into working products quickly. This includes launching MVPs, scaling existing platforms, improving slow websites, fixing complex bugs, automating repetitive workflows, building dashboards, integrating external services, and modernizing older systems. Whether you need a new website, SaaS platform, mobile app, AI-based tool, custom automation, API integration, e-commerce solution, or support for an existing project, I focus on clear communication, practical planning, clean code, and reliable delivery. Send the project details, current website, repository, or requirements, and I will review the best approach for moving it forward.
