Welcome to kodav.dev

This guide is designed for our partners and clients. In 2025, developing a website or mobile app is not just about “writing code”—it’s about creating a digital asset capable of competing in a saturated, fast-paced, AI-driven market.

On this page, we explore the essential characteristics that every project handled by the kodav.dev web unit (part of marfcode.it) must possess.

1. Performance: Beyond Speed

Speed is no longer a luxury; it is a fundamental business requirement. Recent studies show that a delay of just 100 milliseconds can slash conversion rates by up to 7%. In 2025, users expect instantaneous experiences and won’t tolerate waiting.

Core Web Vitals

We optimize specific metrics that Google uses to evaluate user experience:

LCP (Largest Contentful Paint): Main content must load in under 2.5 seconds. We use lazy loading, image optimization, and pre-fetching techniques to achieve this goal.
INP (Interaction to Next Paint): The interface must respond to user interactions in under 200ms. We optimize JavaScript, avoid blocking scripts, and use Web Workers for heavy operations.
CLS (Cumulative Layout Shift): We eliminate annoying page “jumps” during loading by reserving space for images, ads, and dynamic content.

Edge Computing and CDN

We distribute static content (images, CSS, JavaScript) on global CDNs with presence in over 200 locations worldwide. When a user in Tokyo accesses your site, they receive files from a server in Japan, not Europe. This reduces latency from seconds to milliseconds.

For dynamic content, we use edge functions that execute code as close as possible to the user, drastically reducing API response times.

2. Mobile-First & Cross-Platform Experience

Over 70% of global traffic now occurs on mobile devices, and this percentage continues to grow. We don’t just make a site “responsive”: we design the mobile experience as an absolute priority.

Mobile-First Design

We design the interface starting from the smartphone, where user attention is limited, space is precious, and connectivity may vary. This approach ensures:

Essential interfaces, free of superfluous elements
Navigation patterns optimized for thumbs, not cursors
Properly sized touch targets (minimum 48x48px)
Content prioritized by relevance, not space availability

Only after perfecting the mobile experience do we expand it to tablets and desktops, adding features that leverage the extra available space.

Progressive Web Apps (PWA) and Hybrid

For projects requiring app store presence but with limited budgets, we create Progressive Web Apps and hybrid applications that work perfectly on iOS, Android, and Web with a single codebase.

This approach reduces development and maintenance costs by 60-70% compared to separate native development, without sacrificing performance or user experience. PWAs can be installed as native apps, work offline, and send push notifications.

3. Zero-Trust Security and Privacy

In a world of constant cyber threats, daily data breaches, and increasingly stringent regulations, security cannot be a final addition. We integrate it from day one of development (Security by Design).

End-to-End Encryption

All data, both in transit and at rest, is protected with modern cryptographic algorithms:

HTTPS/TLS 1.3 for all communications
Database encryption with keys managed via KMS (Key Management Service)
Secure password hashing with modern algorithms (Argon2, bcrypt) with unique salts

We ensure every solution complies with European privacy regulations (GDPR) and international ones (CCPA). This includes:

Law-compliant cookie consent
Right to erasure (user data deletion)
Data portability (data export)
Privacy by design and by default
Complete audit trails to demonstrate compliance

We protect your company from fines that can reach 4% of global annual revenue.

Modern Authentication

We implement modern access systems that balance security and user experience:

Multi-Factor Authentication (MFA): Two-factor authentication via SMS, email, or authenticator app
Biometrics: FaceID, TouchID, fingerprint for mobile devices
Single Sign-On (SSO): Integration with Google, Microsoft, Apple for simplified login
Passwordless Authentication: WebAuthn and passkeys to completely eliminate passwords

4. Headless & Composable Architecture

We abandon rigid monolithic systems (traditional WordPress, Drupal) in favor of modern, flexible, and scalable architectures that separate frontend, backend, and services.

Headless Backend

We completely decouple the software engine (backend, database, business logic) from its interface (frontend). This allows you to:

Completely change the site design without touching the backend
Create a mobile app that uses the same API as the website
Serve content on smartwatches, digital signage, voice assistants
Replace frontend technologies without rewriting the entire application

The backend exposes RESTful or GraphQL APIs that can be consumed by any client.

Composable Architecture (MACH)

We follow MACH principles (Microservices, API-first, Cloud-native, Headless):

Microservices: Each feature is an independent service that can be developed, deployed, and scaled separately
API-first: Every feature is accessible through well-documented APIs
Cloud-native: Architecture designed to leverage cloud advantages (auto-scaling, resilience, global distribution)
Headless: Frontend decoupled from backend for maximum flexibility

AI Integrations

The future is AI-powered. We prepare software to easily integrate artificial intelligence engines:

Semantic search: Natural language understanding instead of keyword matching
Content personalization: Algorithms that show relevant content for each user
Chatbots and virtual assistants: Automated 24/7 customer support
Workflow automation: Automation of repetitive processes through AI

A modern application must be inclusive and usable by everyone, regardless of visual, auditory, motor, or cognitive disabilities. This is not only ethical and often legally required, but brings concrete business benefits.

WCAG Compliance

We follow WCAG 2.2 (Web Content Accessibility Guidelines) at AA level or higher:

Keyboard navigation: All features accessible without a mouse
Screen reader compatibility: Semantic markup and ARIA labels for blind users
Color contrast: Minimum 4.5:1 contrast ratio for text
Alternative texts: Descriptions for images, icons, and non-textual content
Focus indicators: Clear visual indicators when navigating with Tab

Business Benefits of Accessibility

Improved SEO: Google rewards accessible sites with higher rankings
Expanded market: 15% of the world’s population has some form of disability
General usability: Accessible sites are more usable for everyone
Legal risk reduction: Many jurisdictions require accessibility by law
