I'm an Integration Specialist based in Barcelona, working with B2B integrations and Managed File Transfer (MFT) systems.
In my daily work, I manage enterprise integrations using technologies such as IBM Sterling B2B Integrator and GoAnywhere MFT. My work includes file transfer flows, SFTP integrations, APIs, automation, production environments and solving incidents between different systems.
Outside of my main job, I work as a freelance software developer with clients that I find and manage directly.
I manage these projects end-to-end, from understanding the client's requirements and defining the technical solution to development, testing, deployment and production.
This also includes the infrastructure around the application, such as cloud services, databases, domain purchase and DNS configuration. At the end of the project, I make sure that the repositories, domains, infrastructure and services are under the client's control, so they have full ownership of their product.
For these projects, I mainly work with Python, Django, React and PostgreSQL, using services such as Cloudflare, Railway and Vercel.
I'm particularly interested in integrating LLMs into real applications and existing backends.
I have built and tested LLM flows for client projects where the model works as an additional service connected to an existing backend. For these projects, I created auxiliary backend services to prepare and provide the information needed by the LLM, keep context between different user messages and control how and when the model is called.
I have also worked on reducing token usage and API costs. In some tests, I was able to keep the cost of a multi-step interaction below €0.01.
I'm currently learning more about LLM integrations, context management, tool calling, AI agents, Model Context Protocol (MCP) and AI-assisted development.

🔒 Most of my recent development work is not public on this GitHub account.
Many of the applications I develop and maintain are private projects for clients. Their repositories are hosted in the clients' GitHub accounts or organizations.
