Abubakar A.

I help teams add practical AI capabilities to existing web, mobile and desktop products. With eight years of software development experience, I can handle the complete system around an AI feature—the interface, APIs, business logic, integrations and cloud deployment. One of my recent projects involved building a Vapi conversational agent for a Medusa-based e-commerce application. I connected Vapi to Node.js webhook endpoints so users could search products and perform basic e-commerce actions through a natural conversation. I have also worked on prompt-engineered applications that send structured prompts to GPT, Claude, Gemini and Grok, process their responses and present useful answers or generated solutions inside the product. I’m a good fit when you need to: - Add GPT, Claude, Gemini, Grok or another AI model to an existing application - Build a conversational or voice-based product experience - Connect an AI agent with APIs, databases and business systems - Create the React or Next.js interface and Node.js backend around it - Deploy and maintain the solution using AWS or Google Cloud Most of my work starts inside an existing product rather than from a blank project. I’m comfortable understanding an unfamiliar codebase, identifying a sensible first milestone and improving it without disrupting what already works. My core stack includes React, Next.js, TypeScript, Node.js, Electron, React Native, REST and GraphQL APIs, AWS Lambda, Docker and Google Cloud. I have completed Google Cloud learning in AI Commerce Search and Knowledge Exchange for Gemini Enterprise. I am also progressing through an Agentic AI Agents certificate path and have completed its first course. If you have an existing product or workflow that needs an AI capability, send me the current setup and the result you want. I’ll help you narrow it into a practical first release.
