Custom backend development

High-Performance Backend Development: the Engine of Your Product

We build scalable, secure backend architectures that process data with no bottlenecks. We handle users, payments and integrations, connect it to your frontend and take care of the servers. Your platform, always up.

You built the frontend or the AI. We design the backend architecture.

That is where projects stall. You have the vision; we build the infrastructure and the APIs that make it scale.

1
We define the architecture
Your app or spreadsheet sets the course. We analyse your needs and design how the systems will connect, structuring databases optimised for your product.
2
We build the core
We integrate secure authentication, business logic and scalable APIs. All the heavy code is solved so you can focus on the user experience.
3
We deploy and operate it
Servers, integrations and backups stay in our hands. You ship your product; we keep the infrastructure running at its best without costing you time.

What we build

Not sure where to start? We analyse the backend, spot the bottlenecks and draw up a plan to improve security, scalability and efficiency. Whether it is tuning performance, migrating to the cloud or a full architecture rewrite, our team will help you do it right.

Enterprise architectures
We build the core logic of your corporate software. Secure, high-availability infrastructures built to process large volumes of data and keep daily operations running without interruptions.
API & microservices development
The perfect bridge for your digital ecosystem. We design and build fast, secure RESTful APIs for real-time communication, smooth data exchange and third-party integrations.
Architectures for SaaS platforms
We power your software-as-a-service model. Scalable cloud backends with multi-tenant architecture, recurring subscription management and hardened authentication systems.
E-commerce engines
Robust processing for high-traffic stores. We solve the complex logic of your e-commerce: real-time inventory, shopping carts, shipping calculation and catalog sync, so your sales never stop.
Payment gateway integration
Secure, frictionless transactions. We connect your platform with Stripe, PayPal, MercadoPago or custom solutions, adding fraud protection and guaranteeing regulatory compliance on every charge.
Admin panels (backoffice)
Absolute control over your platform. We build private management interfaces (dashboards) so you can monitor metrics, manage user roles and run your business logic from one place.
Automation & custom CRMs
We centralise your business intelligence. We build backend data engines to manage customers, automate repetitive workflows and connect all your internal tools, removing manual tasks.
Headless CMS
You get full control of your content. Custom backend systems with advanced permission and media management, built headless and ready to be consumed via API by any frontend, mobile app or portal.
Distributed systems & high availability
For products that cannot fail. We structure your application load across independent services, ensuring redundancy, minimal response times and automatic failover.

We work with industry leaders

The same services that power the world’s most demanding platforms.

Your data, isolated: Encryption in transit and at rest, per-client isolation and backups. Your privacy is yours.
Always running: 24/7 monitoring with automatic alerts. If something breaks, we know before you do.
Real support: Humans answering in English and Spanish, within 48 business hours. No bots running you in circles.

Frequently asked questions

It depends on the architecture your product needs, but you know before we start. In our first meeting we define the infrastructure requirements and send you a fixed quote. No hidden costs or surprises during implementation.

API development or point integrations can be solved in days; a complete backend architecture, in weeks. We deliver a technical roadmap with clear milestones before writing the first line of code, and we meet the agreed deadlines.

We specialise in building scalable environments with TypeScript, Node.js, Express, MongoDB and Redis. We containerise applications with Docker and orchestrate deployment on robust infrastructures like Google Cloud. We adapt the tools to guarantee maximum performance for your platform.

Yes. We migrate your current data and services to modern architectures without interrupting your operation. We run these processes with automated backups and contingency (rollback) plans to guarantee zero data loss.

We operate the whole environment. 24/7 monitoring, database optimisation, security updates and continuous delivery stay in our hands so you can focus exclusively on growing your product.

Absolutely. We plug into your current team as a specialised technical partner. We build the core logic and document the APIs so your developers can focus 100% on the interface and user experience.

We implement architectures with multiple security layers from day one. This includes robust authentication (such as JWT or OAuth protocols), encryption of sensitive data in transit and at rest, and strict CORS and firewall configuration. We design the core logic following industry standards to protect your platform against vulnerabilities.

Absolutely. We design the backend for high demand and scalability. We use elastic cloud infrastructures and optimise database queries so the system allocates more resources automatically when traffic grows. Your application will not suffer outages or bottlenecks at its best moments.

We adapt to the model that best serves your business stage. In our main managed infrastructure service, we keep the ownership of the codebase; this lets us offer you a robust, optimised backend engine with continuous maintenance at a much more accessible cost. However, if investment requirements or company policies require full intellectual property, we also offer a development service with complete transfer of source code and repositories.

We work in an agile, bureaucracy-free way. We keep direct communication and ship periodic deliveries so you see real progress. You get access to a staging environment where you can connect your frontend and validate that the APIs and integrations work perfectly before going to production.

Our server operation service includes active 24/7 monitoring. If an anomaly shows up, our early alert systems notify us instantly so we can apply fast fixes. We also keep disaster recovery plans so your platform is never left adrift.

We deliver the backend along with detailed, clear technical documentation (using standards such as Swagger or Postman). Your developers get full detail on every endpoint, data schemas and request/response examples, which guarantees a fast, frictionless integration.

Yes, we build custom API integrations. If the platform you use (whether a corporate CRM, an ERP system, marketing tools, or e-invoicing software) has an API, we connect it and centralise all the business logic so information flows automatically.

In our managed infrastructure model, we design the architecture to guarantee high availability (uptime). We implement load balancers and redundancy to ensure your application is always operational. We get ahead of problems with preventive maintenance to meet the highest industry standards.

Our builds are modular and agile. We construct the architecture thinking about your business evolution. If in a few months you need to add new payment methods, push notifications or Artificial Intelligence integrations, the system will be ready to scale and take on those modules without rewriting the codebase.

Absolutely. We understand data is your most valuable asset. We can build custom admin panels (dashboards) or connect third-party observability tools so you can audit logs, monitor key metrics in real time and manage the activity of your users independently.
