Hi, I'm Mateus 👋

I'm a Cloud & Software Engineer based in Italy, focused on building practical, secure and scalable software products.

I like working at the intersection of *cloud infrastructure, **full-stack development, **privacy-first systems, **automation, and occasionally *creative technology.

Most of my work revolves around turning complex workflows into usable products: from social-service platforms and ticketing systems to ETL migration tools, dashboards, AI-assisted interfaces and cloud-native applications.


What I do

  • Build full-stack applications with *React, **Next.js, **Spring Boot, *Firebase and Google Cloud Platform
  • Design cloud architectures with a strong focus on *security, **GDPR, *multi-tenancy and maintainability
  • Work on SaaS products involving authentication, billing, permissions, file storage, reporting and operational workflows
  • Automate data and migration processes using *Python, **YAML, **SQL transformation tools, **dbt, *Databricks and cloud services
  • Experiment with creative and technical ideas, from visual tools to audio, hardware and creative coding

Current focus

I'm currently exploring and building products around:

  • Privacy-first SaaS platforms for social services and third-sector organizations
  • Firebase/GCP-based multi-tenant systems
  • Secure document and case-management workflows
  • Cloud automation and migration tooling
  • A standalone-first product idea: some secret program creative files, starting from Photoshop/PSD files, will ser in the future 🧐

Tech stack

Frontend

React Next.js TypeScript Tailwind CSS

Backend & Cloud

Firebase Google Cloud AWS Spring Boot

Data & Automation

Python dbt Databricks PostgreSQL

Other tools I often touch

Terraform Docker Stripe


Projects and areas I care about

🤝 Quadro Sociale / GPC-style platforms

I'm building and researching systems for managing social-service workflows: people, access records, documents, operators, structures, permissions, reminders and reporting.

The goal is to create software that is useful in real organizations, especially where data protection, traceability and usability matter.

Key themes:

  • Multi-tenant architecture
  • Role-based access control
  • Firebase Auth and session cookies
  • Firestore security rules
  • GDPR-aware document storage
  • Per-structure permissions
  • Auditability and future reporting

⚙️ Automation and ETL migration

I have worked on tools that automate migration from legacy data platforms and ETL systems toward modern cloud data stacks.

I like building frameworks that reduce repetitive work and make complex migrations more predictable.

Areas involved:

  • Python automation
  • YAML-driven configuration
  • SQL parsing and transformation
  • dbt, Databricks and Matillion-style targets
  • Legacy systems such as ODI, Informatica and stored procedures

🎟️ Event and ticketing systems

I have built systems around event ticketing, payments and operations, including:

  • Stripe payments
  • GCP Infrastructure
  • Mobile and web interfaces
  • On-site validation flows
  • Operational tools for real-world events

Creative tech

Outside strictly business software, I'm interested in creative and experimental technology:

  • Creative coding
  • Audio and visual systems
  • Hardware experiments
  • Tools for designers and creators
  • Version control ideas for visual/creative files

How I think about software

I like software that is:

  • Useful before it is flashy
  • Secure by design, not patched later
  • Understandable by the people who need to use it
  • Scalable enough, without unnecessary complexity
  • Respectful of data, especially when dealing with sensitive contexts

I'm especially interested in products where engineering, operations, privacy and real human workflows meet.


Currently learning / exploring

  • Better SaaS architecture for Firebase and GCP
  • Advanced Firestore authorization patterns
  • Privacy-preserving application design
  • Creative-file versioning
  • AI-assisted workflows that actually help users instead of adding noise
  • More robust cloud infrastructure and deployment practices

Languages

  • Italian — fluent
  • English — fluent
  • Portuguese — conversational
