Custom Software Development for Companies in Barcelona
At MiT Software we develop custom software for mid-size and large companies that have reached the limits of what standard market solutions can offer them. When your business has unique processes, proprietary workflows or requirements that no commercial software covers satisfactorily, the solution is to build exactly what you need. Our team of over 50 engineers covers the entire development lifecycle: requirements analysis, solution architecture, UX/UI design, backend and frontend development, integration with existing systems, testing, deployment and ongoing maintenance. We work with the most in-demand technologies on the market — React, Node.js, Java, Python, .NET, AWS, Azure — and follow agile methodologies that guarantee frequent deliveries and continuous alignment with business needs.
We start each project with a structured requirements gathering process adapted to each Barcelona company's context: interviews with key stakeholders, documentation of current processes, identification of improvement opportunities, definition of functional and non-functional requirements and agreement on project success criteria before writing a single line of code.
Based on the defined requirements, we design the technical architecture of the solution for your Barcelona company: system components, technologies for each layer, integration patterns with existing systems, non-functional requirements — performance, security, scalability — and effort estimation and implementation plan.
Before writing code, we design the user experience for your Barcelona company's software: information architecture, user flows, wireframes and interactive prototypes that we validate with real users before development. Good UX design prevents costly changes during development and guarantees a product that people actually want to use.
We work in short 2-week sprints, delivering functional software at the end of each one. For Barcelona companies, this means seeing tangible results from the first weeks, being able to give feedback that is immediately incorporated into development and adjusting the scope based on what is learned as the product evolves.
Every feature we deliver for companies in Barcelona goes through rigorous testing processes: automated unit and integration tests, end-to-end testing, security testing, performance testing and user acceptance testing. We do not deploy to production until we are confident the software works correctly in all relevant scenarios.
We manage the production deployment, configure monitoring and alerting environments and provide training for your Barcelona company's teams that will use and maintain the software. During the weeks after launch we provide intensive support to quickly resolve any issues that may arise in production.
Barcelona companies that have grown beyond what standard software can offer them need custom technology solutions. We build software that reflects exactly how your business in Barcelona operates — with your specific workflows, automations and integrations — without the limitations or unnecessary functionality of generic market solutions.
The custom software we develop for companies in Barcelona is designed with future growth in mind: scalable architecture that supports increases in users, data and functionality without complete rewrites, modular design that allows adding new capabilities without impacting existing ones and modern technology that will remain maintainable for years.


We develop web applications of any complexity for Barcelona companies: internal management portals, customer self-service platforms, operational tools, marketplaces or any other web solution your business needs. We use modern frameworks like React, Vue or Angular on the frontend and Node.js, Java, Python or .NET on the backend.


We design and develop REST and GraphQL APIs that expose the functionality of your Barcelona company's systems to other applications, mobile clients or external partners. We also design microservices architectures for companies that need to scale different parts of their system independently and deploy more frequently.


We integrate custom software with any existing system in your Barcelona company: SAP, Salesforce, HubSpot, Dynamics, Oracle or any other ERP, CRM or third-party platform. We develop bidirectional integrations that keep data synchronized between systems without manual intervention, eliminating double data entry and consistency errors.


We help Barcelona companies migrate from outdated applications that hinder innovation and make maintenance difficult to modern architectures. We analyze the existing system, define the most appropriate modernization strategy — refactoring, re-platforming, re-architecture or gradual replacement — and execute the migration minimizing risk and operational disruption.


We develop native and cross-platform mobile applications for iOS and Android that extend the capabilities of your Barcelona company's systems to mobile users. Whether it's a customer app, an internal tool for field teams or a B2B solution, we build mobile apps with the same quality and attention to detail as our web solutions.


Delivering the software is just the beginning. For Barcelona companies, we offer continuous maintenance and evolution services: bug fixes, performance improvements, new features, dependency updates, security patches and technical support for your team. We become the long-term technology partner your organization needs to keep growing.
