PeeYai
Processing 200K+ data points/day at launch
PeeYai needed a full-stack AI data curation platform from scratch — ingestion pipeline, vector search, curator dashboard, and public API. Built in 10 weeks. The system handles Thai-language NLP, semantic deduplication, and real-time quality scoring. Still running on the same architecture 18 months later.

FAQ
Development Questions
Why Next.js instead of WordPress?
Next.js loads in under 1 second, scores 95+ on Google PageSpeed, and has no plugin vulnerabilities to patch. For businesses that care about SEO and performance, it is not a close comparison.
How long does a website take to build?
A standard business site takes 2-4 weeks. Custom web apps and AI integrations take 6-12 weeks depending on scope. We move quickly because we write clean code from scratch.
Do you work with Thai businesses?
Yes. We work in English and Thai. All projects include Thai payment gateway options (PromptPay, 2C2P) and LINE integration as standard where relevant.
Can you take over an existing codebase?
Yes, with a code audit first. We review the existing architecture and give you an honest assessment before committing. We only take over projects we can actually improve.
