I design and build , from the idea to the working product.
I build the system your company still runs by hand today.
I'm a software developer working independently. 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. I run that side under my automation agency, Dorvia.

Custom systems and apps, complete and ready to use: from the first sketch to a working product.
I take manual, repetitive work and leave it running on its own, with clear rules and a record of everything that happens.
Getting the different programs a business uses to talk to each other, so no one copies and pastes data by hand.
Assistants that answer questions, organize information and work over the business's own data.
From the idea to a working product, no detours. This is how I run every project:
Before proposing anything, I dig into how the business works to grasp what actually needs solving.
I define how it looks and works, favoring simple and scalable over over-engineered.
I code it end to end and integrate it with the tools the client already uses.
I get it running and keep supporting it as the product grows.

AI assistant for websites
An artificial-intelligence assistant with each business's identity, added to the site in a single step. It answers about the company, with voice and an animated avatar. Includes accounts, subscriptions and statistics.
Every business ships its own AI assistant without writing a line of code.
Futsal clubs
Manage players and live matches from a real-time control panel, with a statistics dashboard, pitch visualization, roles and subscriptions.
Brings squad, live matches and stats together in a single panel.
Assembly guide from a CAD file
You upload a CAD file (STEP) and it generates a step-by-step assembly and welding guide for the workshop: a 3D render of each subassembly, a parts list, and the welds to make detected automatically.
Turns a CAD drawing into a guide the workshop follows on screen.
Also: WhatsApp assistants powered by artificial intelligence, invoicing automation, and internal stock and employee time-tracking systems.
