Freelancer profile translated to English.

Description

Do you have a clear need but no one has turned it into a concrete, documented, and working solution? That's exactly my job.

I am a senior software engineer with over 20 years of experience participating in and leading projects for companies and public administrations: functional analysis, requirements management, team and vendor coordination, and delivery of solutions in production. I have been a developer, architect, project manager, and production director — I know the complete cycle, from requirement to delivery.

I work exclusively on fixed-scope projects, with defined deliverables, start and end dates. No indefinite maintenance or continuous dedication. Fixed budget before starting.

Three collaboration formats:

Functional analysis sprint (3–7 days): from a vague need to a specification ready for development — requirements catalog, use cases, user stories with acceptance criteria, and prioritized backlog. Ideal before hiring development or requesting quotes from vendors.
Automation of a specific process (3–7 days): one process, one working, tested, and documented automation. Odoo, n8n, Make, API integrations.
Technical project diagnosis (2–4 days): blocked project, persistent error, or development that is not progressing — review, probable cause, alternatives, and fixed quote to resolve it.

If you are looking for a senior professional who understands the problem, defines the solution, implements it, and delivers it ready to use — with documentation always included — let's talk.
