Web Development
Fast, accessible, optimized websites that turn visitors into customers.
What's included
Every web development project at ISIO starts with a detailed analysis of business objectives, target audience, and direct competitors. We do not use generic templates — we build from scratch with Astro and TypeScript, two technologies that produce sites with sub-1-second load times and Lighthouse scores of 95-100. This approach ensures every page is optimized for both search engines and user experience.
Our development process follows a clear four-stage methodology: discovery (requirements analysis, competitor audit, sitemap structure), design (mobile-first wireframes, interactive prototypes), development (semantic code, integrated technical SEO, cross-browser testing on at least 5 browsers), and launch (deployment on Cloudflare Workers with global CDN, DNS configuration, SSL, and 30-day post-launch monitoring). Each stage includes an approval checkpoint before moving forward.
All websites delivered by ISIO include on-page SEO optimization from the first line of code: unique titles and meta descriptions per page, correct heading structure (H1-H6), Schema.org structured data, hreflang for bilingual sites, auto-generated XML sitemap, and canonical tags. We do not consider a site finished until the technical SEO audit confirms zero critical errors.

What you get
At project completion you receive the full source code, documented and versioned in Git. We include a content editing guide tailored to the chosen CMS (Sanity, WordPress, or Astro Content Collections), so you can update text, images, and pages without technical assistance. The 30-day post-launch support covers bug fixes, minor content adjustments, and assistance with Google Search Console and Analytics setup.
- Complete source code with documentation
- Lighthouse score 90+ on all categories
- CMS content editing training
- 30 days post-launch support
Our workflow
Working with ISIO starts with a free 30-45 minute discovery call where we discuss project goals, target audience, and available budget. After the call, you receive a detailed proposal with technical specifications, phased timeline, and fixed price — no hidden costs or vague estimates. Once the proposal is accepted, work begins immediately with the structuring and wireframing phase.
Throughout development, communication is direct via email or WhatsApp — there are no intermediaries or ticketing systems to slow down the process. At each milestone you receive a live preview link to test and provide real-time feedback. Changes are implemented within 24-48 hours, not weeks. This agility is possible thanks to ISIO's lean structure — full focus on your project, without the overhead of a traditional agency.
Launch includes complete setup: DNS, SSL, redirects, Google Search Console, Google Analytics, and final testing across all devices. During the first 30 days post-launch, I actively monitor Core Web Vitals and resolve any technical issues at no additional cost. The goal is for your website to perform flawlessly from day one.

Frequently asked questions
How long does website development take?
A standard presentation website with 5-10 pages is delivered in 14-21 days. More complex projects with CMS, blog, multilingual support, or third-party integrations require 30-45 days. Each project starts with a detailed timeline agreed during the discovery phase, and progress is communicated weekly.
What technologies do you use for development?
The primary stack includes Astro (static generation framework with SSR support), TypeScript (for type-safe, maintainable code), Tailwind CSS (for rapid responsive design), and Cloudflare Workers (for global hosting with sub-50ms latency). For CMS, we recommend Sanity (headless) or WordPress (if the client already has content there). We choose technology based on project needs, not personal preferences.
Can I edit the website content myself after launch?
Yes. All projects include a CMS (content management system) and a 1-2 hour training session where we teach you to edit text, images, add new pages, and manage basic SEO. You also receive a written step-by-step guide. If you encounter difficulties in the first 30 days, post-launch support is included at no extra cost.
Will the website be mobile-optimized?
Absolutely. We develop mobile-first, meaning the design is created for small screens first and then adapted for desktop. We test on at least 5 browsers (Chrome, Safari, Firefox, Edge, Samsung Internet) and on real devices, not just emulators. All interactive elements meet the minimum 48x48px size for touch targets, following Google recommendations.
Do you offer redesign services for existing websites?
Yes, ISIO offers complete redesign and migration services for existing websites. The process begins with an audit of the current site evaluating performance, SEO, accessibility, and user experience. We preserve existing content and URLs (to avoid losing SEO positions), improve the design, update the technology stack, and optimize loading speed. Migration includes 301 redirects for all modified URLs and verification that no indexed page returns 404 errors.
