You get everything you need to grow online: website design (custom-built with CMS and SEO), website migration (moving to modern platforms), web applications (custom platforms, internal tools, and customer-facing products), SEO (technical and answer engine optimisation), and website maintenance (monthly retainers). Not sure what you need? Let's have a chat and figure it out together. ### What integrations can you build? I've worked with a variety of tools: social media (Instagram feeds, sharing), Google services (Analytics, Maps, Reviews), email (contact forms, newsletters), CMS (Sanity), custom features (quizzes, vouchers, loyalty programmes), payments & booking (Stripe, Calendly), and messaging (WhatsApp). Got something else in mind? Let's talk. If there's an API, there's usually a way. ### How much does a project cost? Every project is different, but here's a rough guide: a simple landing page starts from SGD $3,000, websites with CMS integration typically range from SGD $5,000 - $8,000+, and web applications and custom platforms vary based on scope and complexity. I'm always happy to discuss your idea first. No commitment required. Reach out and I'll give you an honest estimate. ### How long does a project take? It depends on the scope, but generally: a landing page takes around 2-3 weeks, websites with CMS integration take about 4-6 weeks, and web applications and platforms typically take 2-4 months. This includes design, development, revisions, and testing. I'll share a realistic timeline once we've talked through your project. ### What's your development process like? I like to work iteratively, building in code from the start rather than static mockups. The process: Discovery (we chat about your goals and audience), Prototype (I build a working version early), Iterate (we refine through quick feedback loops), Launch (go live with documentation and walkthrough), and Support (30 days included, with optional retainers after). ### Do you offer ongoing maintenance? Yes! I offer monthly retainers to keep your website or application secure, updated, and running smoothly. With a CMS, you can update content yourself. For design changes, new features, or technical fixes, I've got you covered. ### What does a monthly retainer include? The retainer gives you peace of mind. I handle the technical side so you can focus on your business. It includes: uptime monitoring, infrastructure management (hosting, domains, CMS), security & updates, content changes (minor updates each month), priority support (direct access with faster response), and discounted dev work for bigger changes.
