Answers Before You Ask
Both. Infiteq builds everything from fast marketing websites and WordPress sites to full-blown SaaS platforms, e-commerce storefronts and internal tools. The same senior team handles design, frontend, backend and hosting, so you do not have to stitch together three agencies for one web presence.
A marketing website or WordPress build typically ships in 2–4 weeks. A well-scoped MVP usually ships in 4–6 weeks. Production SaaS platforms with billing, multi-tenancy and integrations typically take 10–14 weeks. We work in two-week sprints with AI-accelerated delivery, so you see a live staging build early.
WordPress is the right call when your marketing team needs to edit pages, blogs and landing pages themselves without involving a developer, and when you rely on a rich plugin ecosystem. Next.js is the right call when performance, SEO, custom UI and long-term code quality matter more than in-place editing. Infiteq ships both and will recommend honestly based on your team and goals.
For most stores, Shopify is the fastest path — best-in-class checkout, payments and logistics baked in. We extend it with custom themes and headless Next.js storefronts when brand and performance matter. WooCommerce makes sense when you are already on WordPress. For unusual catalogs or B2B flows, we build custom commerce on Next.js plus Stripe.
Our default modern stack is Next.js, React and TypeScript on the frontend, with Node.js, PostgreSQL and Prisma on the backend, deployed to Vercel or AWS. For CMS-driven sites we build on WordPress, often with custom ACF blocks, or on headless CMSes like Sanity and Contentful. Every stack choice is justified against your scale, team and long-term maintenance.
Yes — legacy modernization is a strong area. We migrate outdated WordPress, Angular, Rails, Laravel and older React codebases to modern Next.js and TypeScript, with an incremental strangler-fig approach so your site stays live during the rebuild. Data integrity, SEO preservation and zero-downtime cutover are the default, not the upsell.
Absolutely. We set up CI/CD on GitHub Actions, deploy to Vercel, AWS or Cloudflare, and wire in Sentry, Datadog or Grafana for monitoring. Post-launch, most clients keep us on a monthly retainer covering uptime, security patches, performance tuning and new feature delivery — with a named senior engineer on point.
