Portfolio / Medical Projects
Web ECG explorer for bracelet
Web‑based explorer for short ECG recordings from a wearable bracelet. Uploads noisy signals, applies adaptive filtering (wavelets + IIR) and a CNN‑based neural network to automatically recognize cardiac events (normal, extrasystole, artifact). Implements user‑annotation fine‑tuning: the doctor corrects labels, the model updates online without full retraining. Interactive zoomable chart, report export, confidence scores.
DLL plugin for BLE with ECG/BP recorders
Universal DLL‑based communication module for BLE/USB interaction with a set of wearable ECG and blood pressure (BP) recorders. Implements measurement parameter programming, remote start, background reading with data buffering. Built‑in packet integrity checks and automatic reconnection on signal loss. Delivered as a plugin for a desktop application (Delphi / C++), easily integrated via exported functions.
ECG Detection Quality Validation Service
REST API service for validating ECG signal detectors. Upload your recordings and the recognition module to test; the service compares its performance against ground‑truth annotated library records and provides a detailed report on discrepancies and overall quality metrics. Perfect for healthcare startups and research labs.
Neural network system for anatomical structure segmentation
Neural network system for anatomical structure segmentation on MRI scans (bones, organs, lesions). A web resource for distributed DICOM data collection and labeling: radiologists and experts upload scans via browser, annotate contours using interactive tools, and generate ground truth. Role‑based system (admin, expert, labeler), quality control via consensus labeling, and export of annotations for training CNNs (U‑Net, Mask R‑CNN). The model fine‑tunes on new data to improve recognition accuracy.
Portfolio / Educational Projects
Game‑based learning: Python, Java, C++
Engaging programming lessons through game development. Learn Python, Java or C++ by building your own games: from arcades to RPGs. Perfect for beginners and kids.
Test quality analysis based on IRT
Web‑based psychometric analysis tool based on Item Response Theory (IRT). User uploads a test item file and a student response matrix in a convenient format (CSV/Excel). The system automatically calculates item parameters (discrimination, difficulty, guessing) and latent abilities. Visualizes information functions, item characteristic curves, and test function. Generates a detailed PDF report with recommendations for test improvement.
Algorithmic Thinking Test for Applicants
A test for students enrolling in programming courses, assessing basic algorithmic skills before learning any programming language. Tasks include logic puzzles, pattern recognition, sequences, and simple algorithms. The result helps determine a student's readiness and recommend a personalized learning path. No syntax — just pure thinking.
Philosophical Art Association Website
A collection of articles on philosophy and art with a unique publishing system. Authors write articles in RST (reStructuredText) markup, which automatically builds web pages and generates print‑ready PDFs. One source — two output formats, preserving semantic structure and style. Perfect for academic and creative communities.
About Me
I am a software developer focused on medical and analytical systems. I have experience building end-to-end solutions — from low-level plag-in module for wearable ECG and BP recorders to web platforms for psychometric analysis and neural network segmentation of MRI. I cover the full lifecycle: data collection and labeling (DICOM, distributed annotation), building ML models (CNNs, active learning, IRT), and integrating them into final products. I work with noisy signals, extract clinically relevant information, design modular plugins for desktop applications, and create interactive web interfaces for domain experts.
