I design and build , from the idea to the working product.
I build complete apps and systems for businesses and take care of everything: understanding the problem, designing it, building it and getting it up and running. When it helps, I add automation and artificial intelligence so repetitive work takes care of itself. For clients and on my own products.

01About
I'm a software developer working independently under my own brand, Dorvia. I build the product end to end: I define what it has to do, design how it looks and works, build it and connect it to the tools each client already has.
What I enjoy most is solving manual, repetitive tasks with automation and artificial intelligence: taking something a person does by hand every day and leaving it running on its own. I also connect the different programs each business uses, so information flows from one to another without anyone copying it by hand.

01
I understand the problem
Before proposing anything, I dig into how the business works to grasp what actually needs solving.
02
I design the solution
I define how it looks and works, favoring simple and scalable over over-engineered.
03
I build and connect
I code it end to end and integrate it with the tools the client already uses.
04
I stay on
I get it running and keep supporting it as the product grows.

Founder & Full-Stack Developer
Dorvia · Buenos Aires (Remote)
I design and build custom software and automation for businesses: complete apps, connecting the tools they already use, and solutions powered by artificial intelligence, with ongoing support.
- For Desesplast, I built a system that processes the invoices exported by their management software (Bejerman), sends personalized emails, keeps current accounts and employee time tracking, and organizes everything in Google Drive.
- I built E-COMEX, a platform that classifies tariff codes (NCM) with artificial intelligence and calculates the total cost of importing into Argentina.
- I delivered sites and systems for various clients: online stores, internal systems, invoicing automation and WhatsApp assistants powered by artificial intelligence.
