ExtTech

ExtTech is a full-cycle software development company helping startups and businesses build scalable digital products. We specialize in custom software development, AI integrations, SaaS platforms, CRM systems, and web & mobile applications. Our team provides dedicated developers and end-to-end product development from idea validation and UX design to deployment and long-term support.

We build fast, scalable web applications — SaaS platforms, customer portals, admin dashboards and e-commerce. Our core stack is React, Node.js and TypeScript, with clean architecture, REST/GraphQL APIs and CI/CD from day one. You can hire a dedicated team that plugs into your workflow, or have us deliver the full product end-to-end — from discovery and UX to launch and scale. Senior engineers, transparent communication, EU-friendly time zone.

We design and build native and cross-platform mobile apps for iOS and Android. Core stack: React Native and Flutter for cross-platform, Swift and Kotlin for native — with clean UX, offline support, push notifications, payments and third-party integrations. We take products from MVP to App Store / Google Play launch and ongoing scale. Hire a dedicated mobile team that plugs into your workflow, or have us deliver the full product end-to-end.

We design intuitive, conversion-focused interfaces for web and mobile. Our process covers user research, wireframing, interactive Figma prototypes and polished UI — delivered as a scalable design system your developers can build from directly. From product MVPs and SaaS dashboards to landing pages and full redesigns. Design that ships: we work hand-in-hand with engineering, so what you approve is exactly what gets built.

We build AI-powered products and integrations that deliver real business value — not demos. From LLM and generative-AI features, chatbots and intelligent assistants to computer vision, predictive analytics and recommendation systems. We handle the full pipeline: data engineering, model development/fine-tuning, production deployment (MLOps) and integration into your existing apps. Senior ML engineers, pragmatic scope, measurable outcomes.

We set up and run reliable, scalable cloud infrastructure so your team ships faster and sleeps better. CI/CD pipelines, containerization (Docker/Kubernetes), Infrastructure as Code (Terraform) and cloud architecture on AWS, Azure and GCP — plus migrations, cost optimization and 24/7 monitoring. Whether you need a one-off setup or an embedded DevOps engineer, we make your delivery pipeline boringly dependable.

We craft fast, modern websites that convert — corporate sites, landing pages and marketing sites. Clean responsive design, strong performance and SEO-ready code, built on modern frameworks or WordPress/Webflow when that fits best. From a single landing page to a full multi-language website, designed and developed end-to-end.

We build online stores that sell — custom storefronts and platforms on Shopify, WooCommerce, Magento or fully custom. Secure payment integration, smooth checkout, inventory and admin tooling, plus the performance and UX that turn visitors into buyers. From launch to scaling an existing store.
