Engineered for Superior Performance

Our engineering standards are built for speed and security. By bypassing heavy visual builders and monolithic systems in favour of modern headless frameworks like Next.js, we ensure optimal Core Web Vitals and long-term technical reliability.

Core Challenge & Solution

Legacy Monolithic Architecture Restricts Performance and Impedes Growth

Bloated CMS themes, third-party plugin dependencies, and slow page loads do not just frustrate users; they actively degrade your Core Web Vitals and lower search engine visibility. Operating your business on a rigid, heavily patched monolithic system creates substantial technical debt and operational security risks.

“We do not simply build websites; we design and engineer resilient, high-availability digital platforms. In modern B2B commerce, technical stability, security, and rendering speed are the core pillars of digital authority and brand trust.”
Olivier Jacob·Chief Technical Officer
Architecture Framework

Direct Answers

Frequently Asked Questions (FAQ)

Why is Next.js 15 faster and more secure than legacy WordPress or Drupal stacks?
Next.js 15 compiles pages into static HTML and React Server Components at the edge, removing server execution latency and eliminating SQL injection risks inherent in PHP plugins.
What is the average cost to migrate a corporate website from WordPress/Typo3 to Next.js?
Migrations start at 4,480 € (Tier I: 32h) for focused corporate pages and range to 7,140 € – 14,560 € (Tiers II & III) for extensive headless platforms with dynamic CMS integrations.
When should an enterprise choose Astro over Next.js 15?
Astro is optimal for content-first websites and editorial portals requiring absolute zero JavaScript by default. Next.js 15 is preferred for dynamic web applications with complex user states and server actions.
What is the core business advantage of a Headless CMS (Payload / Strapi / Storyblok)?
Headless CMS separates content editors from frontend code. Marketing teams update copy across multiple channels simultaneously while developers maintain strict UI performance without breaking layouts.
How do you guarantee 100/100 Google Core Web Vitals on every page?
Through strict engineering: React Server Components, AVIF/WebP image pipelines, responsive font subsets, sub-300ms TTFB edge caching, and zero render-blocking third-party scripts.
What are React Server Components (RSC) and why do they matter in Next.js?
RSCs execute solely on the server and render pure HTML. They eliminate heavy client-side JavaScript bundles, access backend data layers directly, and drastically reduce client CPU overhead.
How do you ensure zero organic ranking drop during a technical framework migration?
We enforce an exact 1:1 redirect map, preserve HTML canonical tags and metadata structures, and run automated pre-launch regression audits using Playwright to protect ranking equity.
What is Partial Prerendering (PPR) in Next.js 15?
PPR combines instant static edge shell delivery with dynamic streaming holes for personalized data within a single HTTP request, delivering the ultimate blend of speed and dynamic capability.
Why does PHP-based monolith software degrade in performance and security over time?
Monolithic CMS stacks rely on dozens of third-party plugins with unmaintained dependencies, slow database queries per request, and continuous security patching overhead.
How does MyQuests manage engineering projects without in-person meetings?
We run async-first sprints using Linear, GitHub pull requests with ephemeral preview environments, structured Notion roadmaps, and async video walk-throughs for complete velocity and accountability.
Why do you exclusively build with Next.js, React, and Astro instead of WordPress or Typo3?
We rely uncompromisingly on modern frontend architectures. Legacy PHP monoliths introduce security vulnerabilities and slow rendering. With Next.js 15, React 19, and Astro, we deliver sub-second performance, maximum scalability, and 100% long-term investment protection.
How are your project and package prices structured?
Our project and maintenance packages are built on clearly defined milestones and fixed deliverables. With our modular packages, you receive 100% budget certainty, transparent deliverables, and full IP code ownership with zero hidden fees.
Do we own 100% of the intellectual property, code, and deliverables upon project completion?
Yes, completely. Upon full payment, you receive 100% full ownership of all source code, Git repositories, design files, campaign accounts, and data. There are zero licensing dependencies or vendor lock-ins.
How does day-to-day collaboration work in practice?
We operate 100% remote, digital, and async-first via GitHub, Linear, Notion, and Loom. Touchpoints are focused into compact, outcome-driven sprint reviews, eliminating costly travel and meeting overhead.
Do you provide ongoing support and SLAs after launch?
Yes. Through our transparent SLA packages starting at 350 € / month, we provide continuous uptime monitoring, encrypted security backups, Web Application Firewall (WAF) tuning, and core framework updates.
