## Accomplishments

### [DDDS: Distributed Drone Detection System](https://github.com/hapole0n/DDDS-Distributed-Drone-Detection-System)

Real\-time acoustic UAV detector \(Shahed\-136 focus\) in Python, using librosa MFCC features and a Random Forest classifier, with an animated Streamlit dashboard and an interactive 4\-microphone TDOA paper design\. The README describes it as research for defensive early\-warning and notes that detection range and SNR were not measured under controlled conditions in this revision\. Role: repository owner; 1 star\.

### [biblioteka\-db: library management system \(MySQL\)](https://github.com/hapole0n/biblioteka-db)

Library management system built as a relational databases coursework project, using MySQL\. GitHub lists PowerShell as the repository language, and the README mentions CI/CD through GitHub Actions\.

### [Unsupervised analysis of store\-shelf product detector results](https://github.com/hapole0n/projekt-zaliczeniowy-si-kropyva)

Coursework project, kept in a Jupyter Notebook repository, on unsupervised analysis of the results of a detector that finds products on store shelves\. The repository has no GitHub description or stars; its README explains the project\.

### [Co\-authored automotive\-diagnostics monograph chapter](https://www.linkedin.com/in/oleh-kropyva/)

Profile reports co\-authoring “An alternative diagnostic method using on\-board modules as a collection site for essential operating parameters for difficult faults in automobiles”, ISBN978\-83\-943382\-4\-4, using personally collected operating data\. Peer\-review/publication status is source\-reported\.
