Full Stack Developer | API Integration Specialist
Freelance Web Designer • Lavoratore autonomo
Mar 2026 - Present • 5 mos
As a Full Stack Developer and API Integration Specialist, I help businesses build reliable, scalable, and high performing web solutions that streamline operations and improve user experiences. My expertise covers backend engineering, custom web application development, REST API integration, third party service integration, workflow automation, and database design. I have worked on projects involving payment gateway integration, CRM synchronization, e-commerce automation, webhook implementation, authentication systems, and custom backend development for businesses across different industries. Throughout my freelance career, I have collaborated with startups, entrepreneurs, agencies, and growing businesses to solve technical challenges by connecting applications, automating repetitive workflows, and developing custom solutions tailored to their business goals. My experience includes integrating services such as Stripe, PayPal, Twilio, Shopify, WooCommerce, Wix, WordPress, Google APIs, OpenAI, and many other RESTful APIs to create seamless and efficient systems. Beyond API integration, I develop modern, responsive websites and web applications using industry best practices with a strong focus on security, performance, scalability, and maintainable code. Every project is approached with careful planning, clean architecture, thorough testing, and clear communication to ensure reliable, production ready solutions that meet client expectations. I believe successful development is not only about writing code it's about understanding business requirements and delivering solutions that save time, reduce manual work, improve efficiency, and support long term growth. My commitment is to provide high quality work, meet deadlines, and build lasting relationships through professionalism, transparency, and dependable technical expertise.

A fantastic experience from start to finish. The Twilio integration works perfectly, including SMS automation, IVR, voice calls, and A2P 10DLC setup. Professional, knowledgeable, and responsive. I'll definitely be working with William again on future projects.
