Hi, my name is Corvin Gröning

I'm a passionate developer with strong experience in Python and VBA – especially when it comes to automating workflows, building calculation tools for engineers and developing smart, maintainable software. Lately, I've also been exploring Rust – a powerful language that I'm gradually getting more comfortable with.

Writing clean, efficient code is something I truly enjoy. I'm continuously diving into new technologies to expand my skillset. My mission is to craft maintainable and elegant solutions for real-world problems.

Mainly work with:

Category Language/Tool
Languages Python VBA Rust
Data SQL JSON
Tools Visual Studio Code Git Obsidian
Projects Here are some of the projects I'm currently working on:

  • Project Management App

    Built with Python, PySide6 and SQLite – a desktop tool for organizing project details, deadlines, and notes.

  • Terminal Productivity Tool

    Written in Python using Textual and SQLite. Designed to manage tasks in a Kanban-styled view and topic-based notes directly from the command line.

  • Custom GUI Components Library

    A Python package that provides reusable widgets for PySide6 and Tkinter, focused on rapid prototyping and consistent design.

  • Personal Finance Tracker

    Desktop budgeting app built with Excel and VBA – aimed at tracking income, expenses and savings goals.

  • Apple Music Controller

    A native macOS app using Swift and SwiftUI that lets users control playback and manage Apple Music.

  • File Backup Utility

    Developed in Rust, this tool collects files from various source folders and organizes them into a backup structure.

Further experience

Currently learning

C C++

🛠️ Which technologies I use for what

  • Python

    Data analysis, automation, rapid prototyping and tool development

  • VBA

    Quick Excel-based solutions and workflow automation

  • Rust

    High-performance computations and safety-critical applications

  • Java

    Cross-platform desktop applications and future side projects

  • Swift

    Native macOS desktop applications

I enjoy working on GUIs, TUIs, and CLIs alike. For Python I use PySide6, Tkinter and Textual to build desktop GUIs. In Rust I use Slint and Tauri (frontend with web technologies).

I'm constantly learning. Currently:

  • Expanding my Java knowledge to support enterprise environments and revisit planned side projects
  • Exploring C and C++ to deepen my understanding of memory management, low-level operations and performance-critical systems – especially to better grasp the foundational concepts behind Rust.
