// What we build

Real products, not just pretty pages.

Every site or app we ship is built to do work: rank in search, load fast on slow networks, convert traffic into leads, and survive 5 years of edits without rewrites.

Marketing & e-commerce sites

Lightweight, fast-loading marketing sites and Shopify/WooCommerce storefronts. Static-first where it makes sense (this site is one), CMS-backed where editors need it.

Web applications

SaaS dashboards, internal tools, customer portals. Built on Next.js, React, or vanilla stacks depending on what fits — never frameworks for their own sake.

Mobile apps

Native iOS & Android or React Native cross-platform. We ship apps that pass App Store and Play Store review the first time.

UI/UX & design systems

Pixel-perfect, accessible interfaces from Figma to working code. Design tokens, component libraries, and Storybook documentation that survives team turnover.

// How we work

Five steps. No surprises.

Every engagement starts with a fixed-scope proposal. You see weekly progress and you own the code from day one.

Discovery
Short call to scope your goal, audience, technical constraints, and budget. Always free.
Proposal
Fixed-price scope document with deliverables, timeline, and payment milestones. No surprises.
Design & build
Wireframes → high-fi → production code. Weekly review calls; you see progress in a staging environment.
Launch
Deploy to your domain or ours, with monitoring, analytics, and a handover doc your team can run with.
Iterate
Most clients stay on a monthly retainer for content, growth, and incremental improvements.

// Why Kaisync for this

Performance you can measure, not just claim.

We don't believe in vanity scorecards. Every site we ship comes with Lighthouse reports, Core Web Vitals, and live Google Search Console access from day one.

Real performance numbers

This site you're reading scores 95+ on Lighthouse mobile. Our case study findurcollege.com is at average Google position 7.7 across 1.93M impressions — verifiable in GSC.

No framework lock-in

We pick the lightest tool that fits the job. Static HTML for marketing sites, Next.js when you need rendering flexibility, native when mobile matters. You're never trapped.

Accessibility & SEO baked in

WCAG AA contrast, semantic HTML, structured data, sitemap, robots, social meta — done before launch, not bolted on after. Every page passes the audit before it ships.

You own it

No proprietary CMS lock-in. Code lives in your GitHub. Hosting is on platforms you control (Cloudflare, Vercel, Netlify, your own server). Walk away anytime.

// FAQ

Common questions

How long does a typical website take to build?

A marketing site of 5–10 pages: 3–5 weeks from kickoff to launch. A custom web app: 8–14 weeks for an MVP. Native mobile app: 10–16 weeks. Timelines depend on scope and how fast feedback comes back from your side.

What does it cost?

Depends entirely on scope. A simple marketing site starts at a modest budget; a full web app or mobile app is a multi-month engagement. After a free discovery call we send a clear, fixed proposal — no hidden fees, no scope creep, no surprises.

Do you work with existing codebases or only greenfield projects?

Both. We do new builds and we also rescue existing sites — performance issues, SEO regressions, accessibility audits, redesigns on top of an existing CMS. Bring us the messy thing; we'll tell you honestly what to keep and what to replace.

Can you handle hosting, deployment, and ongoing maintenance?

Yes. We deploy to Cloudflare Pages, Vercel, Netlify, AWS, or your own infrastructure — whatever fits your team and budget. Most clients stay on a monthly retainer covering hosting, monitoring, content updates, and small enhancements.

Do you offer SEO and marketing alongside the build?

Yes — that's the point of being a full-stack agency. The same team builds the site, sets up analytics, runs the SEO campaign, and manages paid ads. No friction between vendors. See Digital Marketing and AI Search Optimization.
