As an API Integration Developer, I specialize in designing, building, and maintaining robust backend systems that enable seamless communication between applications. My primary focus is on REST API integration, webhook implementation, and automation workflows tailored to business needs. I have extensive experience working with APIs for ecommerce platforms, particularly Shopify, where I have integrated systems for product management, order processing, and inventory synchronization. I frequently troubleshoot issues such as failed API requests, authentication errors, webhook delivery failures, and real-time data inconsistencies. My technical expertise includes RESTful APIs, JSON data structures, OAuth authentication, and API endpoint configuration. I have successfully connected third-party services including CRMs, payment gateways, and marketing tools to create efficient and scalable ecosystems. Additionally, I build automation workflows using tools like Zapier, Make, and n8n to reduce manual processes and improve operational efficiency. I am highly focused on debugging and performance optimization, ensuring integrations run reliably and efficiently. I identify bottlenecks, fix API timeouts, and optimize request handling for better system performance. Through freelance and independent projects, I have delivered consistent, high-quality solutions with clear communication and fast turnaround times. My goal is to help businesses streamline operations and scale through effective API integration and automation strategies.
