Web Engineering Standards Turnkey Web Architecture

Semantic Markup Without JavaScript Bloat Instant page rendering, accessibility, and clean markup

Adaptive from 320px to 4K Displays Flawless layouts across smartphones, tablets, and wide monitors

Built-in Technical SEO Foundation Structured headings, Open Graph tags, and optimal Core Web Vitals

Web Engineering

Websites Built for Instant Loading and Organic Search

We avoid bloatware CMS solutions and fragile plugin ecosystems. Every web project is compiled with modern static-first architecture (Astro and Next.js) that renders instantaneously, passes Google Core Web Vitals with flying colors, and never incurs plugin subscription fees.

✓

Zero Unnecessary Client JavaScript

Static HTML by default with selective client hydration only for dynamic interactive widgets.

✓

Universal Accessibility & Responsiveness

Flawless presentation from 320px mobile viewports to 4K displays with complete keyboard navigation support.

Mobile & Cloud Systems

From Architecture Spike to App Store Launch and Scaling

We develop mobile clients and cloud APIs as a cohesive, strongly-typed system. End-to-end TypeScript validation from PostgreSQL database queries through to the React Native UI guarantees data integrity and prevents regression bugs.

iOS & Android

Single codebase saves up to 40% in development investment without sacrificing native touch responsiveness.

Multi-Tenant SaaS

Secure customer account isolation, webhook listeners, and automated recurring billing out of the box.

Frequently Asked Questions

Questions About Our Engineering Engagements

How does the transfer of intellectual property and source code work?

From day one, we grant your team access to the private GitHub repository. Upon milestone completion, the source code, project assets, and technical documentation belong entirely to your company. Zero vendor lock-in and zero recurring proprietary fees.

Who manages the project and who will I be speaking with?

Lintelox operates with zero account-manager layers. Communication takes place in a direct Telegram group with our project technical leadership — co-founders Igor (CEO & System Architect) and Emil (COO & Delivery Lead), alongside the senior engineers writing your software.

What is included in the 30-day complimentary post-launch warranty?

Following production release, our team provides 30 days of dedicated warranty coverage. If any deviation from agreed specifications or unforeseen technical regressions emerge, we resolve them with priority status at zero additional charge.
