Shipped in 15 days.
Site, MVP, or App.

Q: React vs Flutter เลือกอะไร?

React (Next.js) สำหรับ web app + SEO-critical site (มี server-rendered HTML). Flutter สำหรับ native mobile app ที่ต้องการ performance + UI ที่ pixel-perfect across iOS/Android. ถ้าต้องการทั้งคู่ — React Native + Next.js หรือ Flutter web build.

Q: Next.js Server Components คืออะไร?

Server Components คือ React components ที่ render บน server เท่านั้น — ไม่ส่ง JS ไป client. ลด bundle size, improve Core Web Vitals, รองรับ async data fetching. ใช้ใน Next.js App Router (13+). Default behavior — ทุก component เป็น Server Component จนกว่าจะใส่ 'use client'.

Q: ทำเว็บไซต์ราคาเท่าไหร่?

ขึ้นกับ scope. Landing page (Next.js) ฿30K-80K. Marketing site (10-20 pages, CMS) ฿80K-300K. SaaS dashboard ฿250K-1.5M. E-commerce platform ฿500K-3M. ใช้ cost calculator บนเว็บนี้คำนวณ instant estimate.

Q: Lighthouse score 100 ทำได้จริงไหม?

ได้ — ในงาน production. ต้องการ: image optimization (WebP + srcset), font strategy (preload + fallback), code splitting, lazy loading, edge runtime, no render-blocking resources. Bluewich's standard delivery target: 95+ mobile / 99+ desktop.

Q: ระยะเวลาพัฒนาเท่าไหร่?

Bluewich's 15-day ship promise. Landing page: 5-7 days. Marketing site (10-20 pages): 10-15 days. SaaS MVP: 15-21 days. Full e-commerce: 21-30 days. Flutter app MVP: 15-21 days. Most products ship within 15 days. Cost Calculator แสดง timeline estimate ตาม features ที่เลือก.

// 01 · DEFINITION

High-end web/app development
— in 1 sentence:

We build fast, accessible, type-safe web/app products using React, Next.js, and Flutter — engineered for scale and maintainability.

ที่ Bluewich เราไม่ใช่ template-shop. ทุก project เริ่มจาก architecture review — เลือก stack ที่เหมาะ (Next.js App Router vs Vite, Flutter vs React Native, Edge vs Node runtime, etc.) ก่อนเขียนโค้ด 1 บรรทัด.

Performance ฝังในทุกขั้น — image optimization (WebP + responsive srcset), font strategy (preload + fallback), code splitting (route-based + dynamic), edge runtime สำหรับ low-latency. ทุก deliverable มี Lighthouse audit + Real-User Monitoring (RUM) setup.

Our work integrates with data-driven content strategy, technical SEO & algorithm work, and CRO + analytics.

// 02 · STRUCTURE

02 · Design System
Tailwind config + component library. Storybook for QA. Accessibility (WCAG AA) baked in.
03 · Build (Iterative)
2-week sprints. Demo every Friday. Code reviews + automated tests. Performance budget enforced via Lighthouse CI.
04 · Performance & Launch
Lighthouse audit until 95+ mobile. Real-User Monitoring (Vercel Speed Insights / Sentry). Soft launch → traffic ramp.
