We design scalable web applications

We develop progressive web applications that combine speed, reliability and native user experience, building modular platforms that adapt to increasing volumes of users and increasingly complex functionalities.

Our scalable web applications evolve with your business, combining modern architectures, intuitive UX and optimized performance to manage traffic growth and evolution over time. For afocused and functional design,we first consider the most used device category with the highest conversion rate: mobile devices. We create sketches of key functions and the sitemap, followed by mobile and desktop layouts on Figma.

We develop complete end-to-end web applications, managing every technological layerfrom the UI to the database. At Riot Design, full-stack development means having integrated skills in frontend, backend, database and infrastructure to create robust and scalable digital solutions.

Our app development agency inEmpoli (Firenze)works with modern technology stacks such as MERN (MongoDB, Express, React, Node.js), LAMP, or customized combinations based on specific needs. From architecture design to production deployment, we follow agile methodologies and DevOps practices to ensure frequent releases, code quality, and long-term maintainability. We create applications that grow with the business, managing increasing complexity without compromising performance or user experience.

We design interfaces for complex web applications that balance information density, usability and aesthetic appeal. TheUX/UIdesign for web apps requires a specific approach that considers articulated workflows, management of large amounts of data, and users who spend daily hours in the application.

We create dedicated design systems, intuitive dashboards, smart forms, and navigation patterns that reduce the learning curve and increase operational efficiency. We optimize for intensive daily use, considering aspects such as reduction of visual fatigue, keyboard shortcuts, informative loading states, and clear error management.

Throughuser research, testing with real users and feedback-based iterations, we develop interfaces that professional users appreciate and that concretely improve productivity. The result is web apps that compete with desktop software in terms of experience and functionality.

We design scalable, resilient, and maintainable software architectures for enterprise applications. System architecture is the backbone of every complex project, defining how components, services, and data interact to support functional and non-functional requirements.

We analyze business requirements, anticipated traffic volumes, integration needs, and technological constraints to define appropriate architectures: monolithic, microservices, serverless, or hybrid.We consider critical aspectssuch as horizontal and vertical scalability, fault tolerance, disaster recovery, caching strategies, and data consistency.

We document architectural decisions, create system diagrams, and define communication patterns between services. We implement observability and monitoring from the outset to identify bottlenecks and issues before they impact users.Our architecturesare designed to evolve, supporting growth in functionality, users, and complexity in the long term.

We build digital platforms where APIs are the core of the system, enabling integrations, automations, and extended ecosystems. TheAPI-drivenapproach treats APIs not as simple technical interfaces but as products that create value for developers, partners, and internal systems.

We designREST and GraphQL APIwith developer experience in mind: interactive documentation with Swagger/OpenAPI, SDKs for popular languages, sandboxes for testing, and transparent rate limiting. We implement versioning, robust authentication (OAuth2, JWT), and comprehensive monitoring of usage and performance metrics.

API-driven platforms allow building web, mobile, and IoT applications that share business logic, enable integrations with external partners, and enable automations that increase operational efficiency. We create the infrastructure that transforms software into a platform, opening new business and partnership opportunities.

We develop enterprise frontends with a focus on performance, maintainability, and developer experience. Frontend engineering goes beyond simpleUI development, requiring expertise in build tooling, testing automation, complex state management, and advanced optimizations.

We implement modern frontend architectures with code splitting, lazy loading, server-side rendering, and progressive enhancement. We useTypeScriptfor type safety, we configureCI/CDpipelines for automated testing and deployment, and implement real-user monitoring to identify production issues.

We manage complexity offrontendapplications with thousands of components, advanced routing, auth and permissions management, and real-time synchronization when necessary. We optimize bundle size, rendering performance, and time-to-interactive to ensure smooth experiences even on less powerful devices. The result is a robust, performant, and pleasant frontend to maintain and extend.

We build scalable and secure backends that manage business logic, data, and integrations. Backend engineering is where the application's intelligence resides: validation, authorization, business rules, data processing, and service orchestration.

We develop with enterprise-ready languages and frameworks such as Node.js, Python/Django, PHP/Laravel, or Java/Spring, choosing based on specific needs. We designrelational databasesandNoSQLoptimized for access patterns, implement multi-level caching with Redis or Memcached, and manage asynchronous jobs with queue systems.

We implement robust APIs, comprehensive error handling, structured logging, and automated testing with significant coverage. We consider aspects such as idempotency, distributed transactions, and eventual consistency when working with distributed architectures. Ourbackend engineeringcreates solid foundations for applications that must handle increasing load, complexity, and enterprise reliability requirements.
