Web Development

Marketing sites, web apps, and platforms that perform — built in Next.js.

Web development at Vellox covers everything from marketing sites to multi-tenant SaaS platforms. We build in Next.js, TypeScript, and Prisma by default — a stack that's fast, SEO-friendly, and easy to hire for. Every engagement ships with responsive design, accessibility, Core Web Vitals in the green, analytics, and a CMS your team can use without us. We don't disappear at launch; most clients stay on a maintenance retainer for ongoing improvements.

What's Included

7 sub-services covering every aspect of web development.

01

Website Development

Build marketing sites and brand platforms that perform. We develop in Next.js, Astro, or Webflow depending on the project's content model and team needs. Deliverables include a deployed, responsive, accessible, SEO-optimized site with a CMS for ongoing content updates. Every site ships with analytics, sitemap, robots.txt, and Core Web Vitals in the green.

02

Web Applications

Build custom web apps for specific business workflows. We develop dashboards, internal tools, portals, and customer-facing applications using React, Next.js, and a modern backend (Node, Bun, or serverless). Web app engagements include architecture, development, testing, deployment, and ongoing maintenance. We default to TypeScript, Prisma, and Postgres unless you have existing stack preferences.

03

SaaS Platforms

Build the next stage of your SaaS product. We work on multi-tenant architectures, billing, auth, role-based access, audit logs, and the UX flows that turn first-time users into power users. SaaS engagements can be greenfield builds or taking over an existing codebase. We ship in weekly increments with demoable features every Friday.

04

Content Platforms

Build content-heavy platforms — publications, directories, learning hubs, marketplaces. We handle the data model, editorial workflow, search, personalization, and the rendering performance that makes large content sites fast. Content platforms are usually Next.js + a headless CMS (Sanity, Contentful, or Payload). The output is a platform that scales editorially and technically.

05

API Integrations

Connect your website or app to the systems it needs to talk to. We integrate with CRMs (HubSpot, Salesforce), ERPs, payment processors, shipping APIs, marketing tools, and internal systems. Integration work includes authentication, error handling, retry logic, monitoring, and documentation. Good integrations are invisible — they just work, even when the upstream API changes.

06

Maintenance & Support

Keep your site secure, fast, and up-to-date. We offer ongoing maintenance retainers covering dependency updates, security patches, content updates, performance monitoring, and bug fixes. Maintenance clients get priority response times and a dedicated Slack channel. Most maintenance engagements also include a small monthly budget for new features.

07

Scaling & Performance

Make your slow site fast, and your fast site faster. We audit performance, identify bottlenecks, and implement fixes — database indexing, query optimization, CDN configuration, image optimization, code splitting, and rendering strategy. Performance work is measured: we ship with before/after Lighthouse scores and Core Web Vitals dashboards.

Our Approach

How we run a web development engagement.

01

Architecture

Data model, API design, tech stack decisions, and a deployment plan. We think through scale, security, and team velocity before writing application code.

02

Build

Weekly increments with demoable features every Friday. We use feature flags, write tests, and keep the production branch shippable at all times.

03

Launch

Staging environment, QA pass, analytics setup, DNS cutover, post-launch monitoring. Launches are non-events because the work is done before launch day.

04

Iterate

Post-launch retainer with bug fixes, performance monitoring, and a small monthly feature budget. The best products are built after launch, not before.
