Full Stack Developer & DevOps Engineer · Barcelona, Spain
In plain words, no jargon: this is what we can do for your business.
We build the software or website your business needs, or improve the one you already use.
For example
We put AI to work for you on concrete, everyday tasks.
For example
We make sure all your technology works, stays up to date and is secure.
For example
We install and maintain the internet and WiFi of your premises or company.
For example
Design and development of websites, landings, e-commerce and internal or inter-company management dashboards.
What we deliver
We cover the full cycle, from the frontend to the API and the database, delivering the product ready for production. Optionally including deployment, CI/CD and separate dev/prod environments from day one. Everything bundled in a single service, so you don't need to coordinate multiple profiles or vendors.
Development of brand-new applications from scratch or extension of existing ones via custom code or standalone microservices that integrate without altering the current system's core.
Our approach
We apply development best practices and separation of concerns adapted to the size and context of each project. The result is maintainable, testable code ready to grow: adding new modules or swapping parts in the future do not require rewriting the system.
New module development for existing ERPs, internal process automation (invoicing, stock, reporting, syncs) and integration between ERPs or with external platforms (CRMs, marketplaces, payment gateways, partner systems).
What sets us apart
Our experience includes building an ERP and working with multiple ERPs along the way. That means we don't tackle each task in isolation: we understand the real business needs and how every automation should fit within the operational flow.
Application migration to AWS, Azure or Google Cloud. CI/CD pipelines with GitHub Actions. Infrastructure as code with Terraform. Containerization with Docker and orchestration with ECS or Kubernetes.
What we deliver
We design scalable and economically viable architectures, sized to what your project actually needs and auto-scaling on demand. You pay for what you consume, not for what you keep running.
OCR pipelines for massive document digitization. Virtual assistants and AI receptionists integrated with telephony. Conversational enterprise bots (WhatsApp, web). Integrations with model APIs (Bedrock, Anthropic, OpenAI).
What we deliver
We automate the repetitive, low-value tasks that drain your team's time so people can focus on what really matters: judgment, decisions and skilled work. The result is a more productive team and processes that scale without needing to grow headcount.
Data migration across platforms, formats or databases, including transformation, validation and schema refactoring when needed.
Our approach
We treat migrations as our own. We meticulously analyze every field, property and value to guarantee a migration with the best possible format without losing any data or property.
Single Sign-On (SAML, OpenID Connect, OAuth2) and second-factor authentication (TOTP) integration in existing applications, with direct coordination with the end client's IT team when federation between organizations is involved.
What sets us apart
It's a feature where the fear of breaking authentication holds many teams back, and rightly so — it carries a lot of responsibility. Thanks to our experience with these integrations, careful work and rigorous prior analysis and research, we guarantee a clean integration with no service interruptions and no impact on the authentication of other dependencies or services that rely on it.
Development of MCP (Model Context Protocol) servers that connect your internal systems (ERP, CRM, databases, your own APIs, management tools) with AI assistants such as Claude, ChatGPT or Gemini.
What we deliver
Your team will be able to ask an assistant to check stock, generate reports, update records or kick off processes talking directly to your systems, without relying on the model's training knowledge or outdated data.
Technical support and systems administration. Server maintenance, user and domain management, workstation, POS and back-office setup, incident resolution and first- and second-level support.
What we deliver
The natural complement to the rest of the services. If we build your software, your cloud infrastructure or your automations, we can also keep them running. A single point of contact for everything related to your technology, without having to re-explain the context every time something breaks.
Review of the state of your infrastructure, servers and applications: configuration, access and permission management, security, backups and deployment best practices. We deliver a report with prioritized findings and actionable recommendations.
What sets us apart
An external, unbiased look at your technology. We spot risks, bottlenecks and areas for improvement before they become a problem, and give you a clear plan of where to start.
Design, installation and maintenance of networks for companies and premises: network hardware (switches, routers, access points), high-density WiFi, VLAN segmentation and captive portals for guest WiFi with email capture and connection time limits.
What we deliver
We make sure the connection is never a bottleneck. Stable coverage across the whole space, a separate and secure guest network, and infrastructure ready to grow without surprises.
Development of complex scripts and custom resources for FiveM roleplay servers. Game mechanics, economy systems, framework integrations (ESX, QBCore), admin panels, custom commands and connection to databases or external services.
What sets us apart
We know the ecosystem from the inside. We have experience building successful servers and we know what makes a server actually work.
Virtual receptionist that understands intent, routes or resolves calls with no human intervention.
Tech lead and developer. Direct meetings with the end client to gather and shape the security requirements.
OIDC between GitHub and AWS — no static tokens or secrets, only short-lived permissions. Concrete case: OCR microservice integrated into the ERP.
Messaging service with automated deployment.
From manual VPS to cloud with CI/CD (preparation).
To speed up dev team onboarding.
From massive databases for downstream analysis.
Automation of internal processes.
Corporate frontends (Munreco and others).
I co-founded and developed roleplay servers during lockdown. “Olvidados” reached the Top 10 in Spain and opened the door to collaborating with other top servers in the ecosystem.
Got an idea? I'll turn it into a real product. Drop me a line and let's start building today.
