Systems engineer · 20+ years · Rosario, Argentina

I design and build complex business systems end to end.

Over two decades working with companies: I gather their needs, understand the business and turn it into software. From the domain model to the electronic invoice issued through ARCA, I cover the whole path in .NET.

Featured project

Management platform

SaaS ERP · multi-company · private beta

A multi-company web ERP for Argentine SMBs: sales, purchasing, treasury, stock, accounting and electronic tax invoicing. It also brings a CRM, inter-user messaging and an API module to connect it with external systems. I designed it from a close read of how companies operate, as a base framework for building modules tailored to each business, with the tax integrations for ARCA and BCRA. It’s currently in private beta.

About me

A systems engineer who enjoys the domain, not just the code.

I’m a systems engineer with over twenty years working side by side with companies: I map how they operate, understand their business and turn it into software. I’m comfortable where the domain is hard: tax rules, double-entry accounting, multi-company.

Full-stack for real: I model the domain, write the API, build the UI, choose the database and set up observability and CI/CD. I like to understand the problem deeply and leave an architecture others can extend.
