At MiT Software we are the reference TypeScript team in Barcelona. We build web applications, APIs and backend systems with static typing for startups and companies that need robust, scalable code. We work from Barcelona with clients across Spain and Europe. If your company needs a senior TypeScript team with a local presence, contact us today.
The TypeScript team in Barcelona combining real technical expertise with local market knowledge
Barcelona is one of Europe's most active tech hubs and companies here demand the same as Silicon Valley: code that scales, teams that deliver and technology that does not turn into technical debt. TypeScript answers exactly that demand. At MiT Software we are specialists in TypeScript development in Barcelona: we work with growth-stage startups, scale-ups that need to strengthen their team and established companies that want to migrate their JavaScript codebase to TypeScript safely. Our team in Barcelona applies strict typing, modular architectures and agile methodologies on every project.
We build complete web platforms with TypeScript, from the frontend with React or Next.js to the backend with Node.js or NestJS. Clean architectures, typed code and on-time delivery.
We design and implement robust APIs with TypeScript, Express, NestJS or Fastify. Full endpoint typing, automatic validations and documentation generated directly from the code.
We convert existing JavaScript projects to TypeScript incrementally, without stopping development. We define types, eliminate implicit any and establish strict compilation rules.
Need to strengthen your team with senior TypeScript developers? We provide specialist talent that integrates into your stack, your methodology and your delivery pace.
We define your TypeScript project architecture from scratch: module structure, dependency management, typing conventions and compiler configuration for long-lived projects.
We review your current codebase, identify typing issues, incorrect patterns and improvement opportunities. We deliver a prioritised action report and execute it with you.
We offer support plans for TypeScript projects in production: dependency updates, incident resolution, performance improvements and continuous technical evolution.
We design and implement microservices architectures with TypeScript and NestJS. Independent, well-typed services with clear contracts between them, ready to deploy in containers or cloud environments.
We train your development team in TypeScript: from typing fundamentals to advanced architecture patterns. Your team adopts TypeScript with purpose, not just obligation.
TypeScript catches errors at compile time before they reach production. With strict typing on every project, we eliminate costly bugs and drastically reduce the time spent debugging and fixing errors in production.
Well-typed TypeScript code stays readable and predictable as the team grows. New developers understand the codebase from day one and refactors are safe, fast and free of unexpected side effects.
TypeScript compiles to standard JavaScript and is compatible with the entire ecosystem: React, Node.js, NestJS, Next.js, Vue and thousands of libraries. You adopt static typing without abandoning any tool or changing your stack.
At MiT Software we have been developing with TypeScript on real projects for startups and companies in Spain, the USA and Europe. We bring accumulated experience, proven architectures and a team that delivers code that scales.
TypeScript catches errors at compile time, before they reach your users. Our developers apply strict typing on every project to reduce bugs and minimise maintenance costs.
As your team grows, well-structured TypeScript code stays readable and maintainable. We design modular architectures that allow new developers to join without losing velocity.
Google, Microsoft, Airbnb and most leading tech companies have adopted TypeScript as their standard. Implementing it in your company is not a trend — it is a proven strategic decision.
Intelligent autocomplete, real-time error detection and self-documenting types speed up development. Your developers produce more with less friction.
TypeScript compiles to standard JavaScript and is compatible with all libraries, frameworks and tools in the ecosystem. You gain typing and robustness without changing your stack.
Typed code documents itself and makes refactors safer. Projects that previously required weeks of analysis to modify can be understood and evolved in days with TypeScript.
At MiT Software we have been developing with TypeScript on projects for startups, scale-ups and enterprises for years. We do not learn on your project — we arrive with proven experience.
With TypeScript, every code change immediately shows which other parts of the system are affected. Refactoring stops being a risky operation and becomes something predictable and controlled.
A well-typed TypeScript project is self-explanatory. New team members understand the structure, module contracts and business logic without needing weeks of onboarding.
