Tech Lead | Full Stack Developer | Ultra-Processed Food & Socioeconomic Patterns Enthusiast

Hi, I'm Patrick Walter. I lead and coordinate a development team focused on mobile and web applications, managing the entire software lifecycle — from architecture planning and implementation to versioning, publishing, and server configuration.

📱 On the mobile side, I define and maintain development standards and best practices across the company, ensuring scalability, maintainability, and performance.
I actively develop offline-first, high-performance applications using:
React Native, React, TypeScript, Redux / Redux Persist, RealmDB, SQLite (TypeORM), Firebase, and styled-components.

💻 On the web side, I design and support complex systems using:
C# (ASP.NET Framework / Core), MVC architecture, Entity Framework, Dapper ORM, Vue.js, jQuery, SQL Server, and Microsoft Azure.
I also build and maintain APIs and manage secure file storage and digital signing infrastructure, leveraging IIS, SeaweedFS, and AES/RSA encryption.

🧠 Outside of development, I'm passionate about dietary and socioeconomic patterns, particularly ultra-processed food consumption.
I use AI and data analysis to explore how social and economic factors influence eating behaviors, inspired by datasets like IBGE’s POF.
