Custom Website Development: Fast, Scalable and Built to Convert
By Sceniox Team · 31 October 2026
React, Next.js, WordPress, e-commerce or a full SaaS portal — Sceniox builds websites engineered for speed, SEO and conversions.
A template can look fine. But the moment you need a specific checkout flow, a membership system, a dashboard, or pages that load in under two seconds on a mobile connection in Dhaka, templates start fighting you. Custom development exists for that moment.
What we build
Frontend in modern stacks — React, Next.js, Vue, Nuxt, Angular, SvelteKit, with Tailwind and component systems, animations and 3D where they serve a purpose, and PWAs that work like apps. Backend and APIs in Node.js, Python (FastAPI, Django), Go, PHP/Laravel or Rust — REST, GraphQL, gRPC or tRPC, real-time websockets, and auth done properly with OAuth2, JWT and Supabase Auth.
Data and platforms: PostgreSQL, MySQL, MongoDB, Redis and queues, Supabase and other backends-as-a-service, and object storage with CDN delivery. Headless CMS (Strapi, Sanity, Contentful, Payload, Directus) or custom WordPress themes and plugins, Webflow and Framer where they fit. Payments including Stripe, PayPal, SSLCommerz and Paddle, with subscriptions where needed.
Types of sites, and what is built in
SaaS platforms and multi-tenant portals, AI-powered web apps and multi-model chat interfaces, corporate sites, high-converting landing pages and portfolios, and learning management and membership portals. Whatever the type, three things are built in from day one: speed, SEO structure, and conversion paths — because a beautiful site that loads slowly, cannot be found, or never asks for the sale is not doing its job.
