"We're very happy with Chima's work, and we're ending this project but still keeping him on our payroll." Those were the words of a happy client in the travel industry after I built an AI-powered travel booking web application. And he's continued to hire me over and over again. Now to you who're reading right..."We're very happy with Chima's work, and we're ending this project but still keeping him on our payroll." Those were the words of a happy client in the travel industry after I built an AI-powered travel booking web application. And he's continued to hire me over and over again. Now to you who're reading right now.. Clients come here when: - they want to build something AI-powered - their product needs to feel smarter. - their search is broken, - or their booking flow leaks users, And they need it built clean. That's the exact gap that gets closed here: Web applications that don't just render, but think and respond. AI woven into search, booking flows, discovery engines, and product logic. That's what I build for companies & businesses where UX directly moves revenue. WHAT I BUILD: 🔍Intent-aware search. Not just keywords. Hybrid pipelines (BM25 + vectors + re-ranking) that surface what users mean. ⚡ AI in live systems: booking flows, real APIs, real inventory. Not demos. Not wrappers around ChatGPT. 🏗️ Frontend architecture that scales: Next.js, TypeScript, component systems built to last. 🌍 Proven in production: currently shipping for a luxury travel group (Sweden/Spain) across trip discovery, cruise search & multi-destination booking. 🏠 Strong fit for: Luxury Travel · Real Estate · E-commerce · SaaS tools where search or AI interaction drives conversions. HOW I WORK: - Every project starts from the user problem, not the tech stack. - Whether it is semantic search, a vector database integration, or a streaming AI interface, the goal is always the same: fewer clicks, faster answers, higher conversions. SERVICES - AI integration into existing frontends. - RAG (Retrieval Augmented Generation) pipeline development. - AI-powered search & natural language search UX. - Next.js application development. - API integration. - Vercel AI SDK implementation. - Prompt engineering for product features. MY CORE FRONTEND SKILLS: - Next.js / React (React Hooks, App Router, Server Components, Server Actions) - TypeScript / JavaScript - Tailwind CSS3, SaSS, SCSS, HTML5, Responsive Design - Framer Motion - Radix UI, Shadcn/UI - React Hook Form, Zod, class-variance-authority - Web Performance, Core Web Vitals CORE AI ENGINEERING SKILLS - AI Integration - Vercel AI SDK - RAG (Retrieval-Augmented Generation) - Vector Database / Pinecone - Vector Search / Semantic Search - OpenAI API / ChatGPT Integration - Google Gemini - LLM Integration - AI Chatbot - Conversational AI: BM25 Hybrid, Search Embeddings, Text Embeddings. - Prompt Engineering, - AI-Powered Search, - Reranking / Reciprocal Rank Fusion. - Chunking - Intent Detection. - Natural Language Search. - AI Search UX / Tool Calling / Function Calling TOOLS & WORKFLOW - Git / GitHub - npm / pnpm - ESLint / Prettier - CI/CD Vercel Deployment - Google Maps API - Claude Code If your users deserve a smarter experience, Then do one thing: click the top-right green button, and LET'S BEGIN!
