Desktop software development with Electron and Tauri
I build Windows desktop applications for business operations. I am Daniel Castellanos (Dnjoc), a freelance developer based in Barquisimeto, Venezuela. I use Electron or Tauri with React to build tools with local data, reports and screens that fit how your business works.
What I can build
- Insurance policy and client management with commission calculations.
- Inventory, purchasing and sales management for shops and other businesses.
- Tools with local data, exportable reports and offline operation.
Technologies and how I choose them
I use React and TypeScript for interfaces, Electron or Tauri for the desktop application, and SQLite for local storage. ComiGest applies Electron to insurance management; ZentriBox uses Tauri for inventory, purchasing and sales. The choice depends on integrations, distribution and device requirements.
TechnologiesScope and delivery
Delivery can include a Windows installer and updates through a custom API when agreed. Before development, we define devices, storage, backups and any synchronization with other systems. I include a 30-day warranty for bugs related to the approved scope; new features and later maintenance are quoted separately.
I work with clients outside Venezuela. Meetings are preferably in Spanish; for English-language projects, we can communicate in writing, as my conversational English is basic.

Questions Clients Ask
Can you build software that works without internet?
Yes. A Windows application can work with a local SQLite database. ComiGest already uses this approach for insurance commissions and policy management. Features that depend on external services or synchronization need an additional connectivity strategy.
Do you use Electron or Tauri for custom software?
I work with both depending on the project. ComiGest uses Electron and React and is currently in use; ZentriBox is in development with Tauri, React and TypeScript. We review integrations, installation and maintenance to choose an appropriate option.
