I practice Vibe Coding daily using Claude Code, Cursor, Lovable, and Base44 to ship production-ready SaaS in days. You have a vague idea, a paragraph, or a PRD? I turn it into a working product with clean UX, Stripe payments, auth, and database. No hand-holding. Just shipping. I combine AI-assisted development with senior full-stack engineering so you get speed AND stability.
I turn complex ideas into scalable, investor-ready web applications in weeks, not months. As a Bubble expert and Full-Stack No-Code Architect, I combine senior-level engineering logic with pixel-perfect UI/UX design to build high-performance SaaS platforms, multi-vendor marketplaces, and AI-powered dashboards that actually scale. Traditional development is slow and expensive. I help founders, startups, and businesses launch faster by architecting clean, maintainable systems using Bubble, API orchestration, and AI integration without the technical debt.
My Vibe Coding Workflow: You share the goal → I write prompts in Cursor/Claude Code → AI scaffolds the UI, logic, and APIs → I manually harden error handling, types, and edge cases → You get a live demo in 48 hours. I fix what AI breaks. I handle masking, API integration, and production debugging so your app is actually ready for real users.
Whether you need a complex marketplace with Stripe Connect, an internal tool with custom workflows, an AI agent leveraging ChatGPT or Claude, a mobile app in Flutter/React Native, a WordPress site, or a Webflow build – I deliver production-grade software that investors and users love. My no-code toolkit includes: Lovable, Base44, Softr, Bubble, Webflow, Airtable, Make, n8n, and Typeform.
Why Work With Me:
I don't just drag and drop. I architect systems. I ensure your database is normalized, your workflows are optimized for speed, and your API integrations like Stripe and OpenAI are bulletproof.

Most developers get close but close isn't good enough when it's your brand. Spacing feels slightly off. The mobile layout breaks. The colors shift. You spend days going back and forth trying to fix it.
I specialise in one thing: turning Figma and PNG designs into pixel-perfect, responsive websites using HTML, CSS, Tailwind CSS, and JavaScript with zero compromise on accuracy. If it's in your design, it shows up in the code.
My name is Muni. I work with designers, startups, agencies, and business owners who have a Figma file or design ready and need it built right the first time in clean HTML, CSS, JavaScript, React and Next.js that actually matches what was designed.

"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 on Freelancer(dot)com
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.
WHAT I BUILD:
AI-powered frontends using Next.js, React and TypeScript.
From AI chatbots and conversational search to full booking systems and RAG pipelines wired into live data.

- 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.
