Transform Ordinary Websites into “Revenue-Generating Assets”

Who Is This Service For?
Not every business needs High Performance systems. We recommend this service if:
This service is for you if:
- You need a website as Core Business and the heart of customer acquisition
- You plan to expand systems, add features, or add massive Content in the future
- You understand a website is an “Investment” generating profit, not just a one-time expense
- You want polished work both front (Design) and back (Clean Code)
This service may not be suitable if:
- You need a website quickly within 3-5 days at a few hundred dollars
- You use the website only as an “online business card” with no updates or customer acquisition
- You don’t prioritize security, customer data, or loading speed
Our Development Process
Mid-to-large clients need confidence in the process. We work in steps like engineering projects:
- Business & Requirement Analysis: Meetings to understand business needs and real Pain Points
- UX Flow & Information Architecture: Structure information and User Journey paths
- Design System & Prototype: Pixel Perfect web design with clickable prototypes
- Development (Modern Stack): Coding with high-level technology, emphasizing speed and security

- Launch & Documentation: Production deployment with user manuals and technical recommendations
Modern Tech Stack
We use world-class technology chosen by major brands, keeping your website modern for at least 5-10 years:
- Frontend: Next.js, React, Vue/Nuxt, Astro (fastest content websites), Tailwind CSS
- Backend: Django, Laravel, Node.js
- Backend & Data: Node.js, Python, Supabase, Postgres
- CMS: Headless CMS (Keystatic, Strapi, Sanity) for easy editing without heavy websites
- Infrastructure: Vercel / Cloudflare for world-class security and Caching
Web App vs Website: What’s the Difference?
We help you choose the right Tech Stack:
- Website: Focus on “Information” (Informative) e.g., company websites, portfolios → Use Astro
- Web App: Focus on “Functionality” (Interactive) e.g., booking systems, payment systems, Dashboards → Use Next.js
Elevate Business with AI Integration
Go beyond normal websites with AI systems we help connect:
- Smart AI Chatbot: Answer deep customer questions using your business data (via GPT/Claude), beyond Rule-based chatbot limitations
- Autonomous Workflow: Order receiving systems summarizing information sent to LINE or Email automatically
- Content Personalization: Display content appropriate to each visitor’s behavior
We migrate websites from every platform
Whether your site is on a Thai site builder, an international platform or an old CMS nobody maintains any more, we move the pages, products, photos and categories, and set 301s for every old link, so the Google rankings you have built up don’t disappear with the old system.
Don’t see your system? Just ask. Some platforms let you export from the admin; for those that don’t, we collect everything from the live pages. If your platform has announced it is closing, start early.
Real example: moving a 1,576-product Porsche parts store from iGetWeb to WordPress · Service details: catalogue migration + technical SEO
Pricing
Pricing is assessed on the size of your site and the actual work: the number of pages, the features you need and how ready your content is. Message us on LINE for a free audit before any work starts. We design the key pages for you to see first, then quote in writing.
