Hi, I'm Diego.

Software & DevOps Developer

From Montevideo, Uruguay

I develop software mainly in .NET/C#, with a focus on integrations, automation, and enterprise systems.

My background in support and infrastructure shapes how I design software, with an eye on operations, failure modes, and maintainability.

One of the systems I built processes around 1,500 operations a day, integrates with six banks, and has been running in production for over a year.

Authoritative multiplayer server in .NET

An authoritative multiplayer server built in .NET with a Unity client. The server owns the game state and validates player movement, combat, and actions in real time.

The hard partIn an online game, the client cannot be the source of truth. The server validates movement and combat, persists character state, and sends each player only the information relevant to their surroundings.

This site: portfolio and CV in Astro

A bilingual portfolio and CV built with Astro and shipped as static HTML on GitHub Pages. The content lives in YAML and the code is public — you can read exactly how it's built.

The hard partThe content exists in two languages and has to keep saying the same thing in both. Each field lives once, in YAML, checked against a JSON Schema on every push: if it fails, CI blocks the deploy before anything ships.

Software Developer

Apr 2024 — Sep 2026

Tecnisegur

Cash-in-transit and security services · Montevideo, Uruguay

I designed and built .NET applications to automate banking, operational, and commercial processes, including integrations with six banks and systems that process around 1,500 operations a day in production.

TAAS — Tecnisegur Automatic Accreditation System

I built a system that automates the bank settlements generated by deposits made into smart safes.

It integrates with six banks through different mechanisms, from file exchange to web services, and processes around 1,500 operations a day with no manual intervention.

It also includes monitoring and reprocessing tools so operators can resolve exceptions without disrupting the system's normal flow.

  • .NET
  • ASP.NET Core
  • WPF
  • MVVM
  • Quartz.NET
  • SQL Server
  • SQLite
  • Azure

Valuables Tracking App

I built an Android app for the operational tracking of shipments through seal scanning, geolocation, and status changes.

It was designed to work offline: it stores operations locally during periods without coverage and syncs them once connectivity is restored.

The app was published and distributed through Google Play.

  • .NET for Android
  • Xamarin.Forms
  • SQLite
  • Google ML Kit
  • Geolocation
  • Google Play Console

Subscriptions and Payments System

I built an internal API that integrates the commercial platform with Mercado Pago to manage payments and subscriptions.

The system handles the full lifecycle of each transaction, including approvals, rejections, expirations, reversals, renewals, and cancellations, and integrates Twilio to send the associated notifications.

  • C#
  • .NET
  • ASP.NET Core
  • REST API
  • Mercado Pago API
  • SQL Server
  • Twilio
  • I maintained and built modules for HR, Sales, Billing, and Treasury on the existing internal ERP built in WinForms.
