I'm Manuel Mansilla Gil, an independent engineer in Madrid. I build data feeds, AI workflows, and web applications, and get them running in production.
You work directly with me, from the first scope discussion through development, deployment, and handover.

I'm Manuel, an independent engineer based in Madrid. There is no account manager or hand-off between us.
On a production web-data platform, I led development of the data engine, owned production components across its services, workers, queues, and AWS, and rebuilt its deployment workflows.
After launch, I can maintain what I build under a defined maintenance plan, or hand it over to your team with documentation.
We agree on the scope, the deliverables, and who will run the system after launch.
We review your workflow and constraints. I set out the first deliverable, open questions, and a delivery plan.
I develop the system in stages, with working software for you to review as it takes shape.
I deploy the system and document how to run it. We agree on a handover or a defined maintenance plan.
Email me a short description of your workflow, current system, and timing, or book a call. I'll help you identify the next step.
