The agency builds any type of application: SaaS platforms, iOS and Android mobile apps, web applications, business back-offices, marketplaces, internal tools, MVPs and AI-powered products. It also takes over and evolves existing applications. Its public portfolio includes 15 projects, across sectors as varied as construction (Travaux Tranquilles), landscaping (Terraxia), automotive (AccesSIV, Nitro, Carburo), restaurants (RestauBooker), real estate (Guy Hoquet), events (TEDx Nantes), mobility (WePark, N'BlaSira), art (Ekinium), music (Musso), customer relations (EasyReview, Luxia) and gaming (AKIKI). Custom development is the operating principle: every project is built specifically, with no CMS, no template and no no-code solution. No building block is imposed by a third-party vendor, which makes it possible to address business requirements that off-the-shelf tools cannot handle. Clients retain full ownership of their codebase and can evolve their platform without dependency. Engagements cover the full cycle, from initial scoping through production release and ongoing maintenance. The technical stack is built on React, Next.js and TypeScript for web, Flutter, Swift, Kotlin and Java for mobile, Node.js and Python on the server, Firebase, MongoDB, AWS and Google Cloud Platform for data and infrastructure, and the OpenAI, Claude, Mistral, Llama and Gemini APIs for artificial intelligence features. Common integrations include Stripe for payments, Algolia for search, Mux for video and SendGrid for email. Technology choices are made project by project, based on the actual requirement. ## Services - [Web & Mobile Design](https://www.eskelia.com/en/services/web-mobile-design.md) : Development of specifications for web and mobile projects, focused on precise user needs analysis. - [UX/UI Design](https://www.eskelia.com/en/services/ux-ui-design.md) : Creation of UI/UX designs to improve engagement on mobile and web interfaces, focusing on intuitiveness. - [Web Development](https://www.eskelia.com/en/services/web-development.md) : Development of websites and web applications, focusing on performance and user experience. - [Mobile App Development](https://www.eskelia.com/en/services/mobile-development.md) : Custom development for Android and iOS, adopting a mobile-first approach with complementary web solutions. - [Backoffice Solutions](https://www.eskelia.com/en/services/backoffice-solutions.md) : Custom backoffice solutions for efficient management on mobile and web, ensuring optimal control of operations. - [SaaS Development](https://www.eskelia.com/en/services/saas-development.md) : Development of custom SaaS solutions for web and mobile, optimized for your business needs. - [Landing Page](https://www.eskelia.com/en/services/landing-page-development.md) : Design of landing pages and web applications, combining attractive design and SEO content to boost conversion. - [Deployment & Maintenance](https://www.eskelia.com/en/services/deployment-maintenance.md) : Deployment and maintenance services to ensure the performance and security of web and mobile applications. ## Projects - [Terraxia](https://www.eskelia.com/en/portfolio/terraxia.md) : Terraxia is a web and mobile SaaS designed for landscaping companies.
