Adeyl RYZYNSKI

Computer Science student (Top 15%) specializing in Backend Engineering and Network Systems. Open-source maintainer with 300+ stars on GitHub.

I design high-performance backend tools, currently transitioning from Python to Golang to optimize concurrency and scalability in distributed systems.


Technical Stack

  • Languages: Python (Advanced), Golang (Intermediate)
  • Backend & Networking: HTTP/2, REST APIs, TLS Fingerprinting (JA3)
  • Databases: PostgreSQL (SQL), SQLite
  • Infrastructure: Docker, Linux, Git, CI/CD

Selected Projects

🌟 Vinted Discord Bot (Python)

Legacy Project - 300+ Stars on GitHub

A widely adopted open-source monitoring tool for the Vinted platform.

  • Impact: Used by a large community to track real-time listings.
  • Engineering: Built with Python and standard scraping libraries.
  • Limitation: Identified concurrency bottlenecks and high memory usage at scale, prompting the re-engineering of a V2 in Go.

Tech: Python, Discord.py, SQLite

🚧 vinted-monitor-go (Work in Progress)

The "V2" High-Performance Rewrite

Re-architecting the monitoring engine using Golang to solve previous scalability issues.

  • Concurrency: Implementing Go routines to increase throughput by 10x compared to the Python version.
  • Network Analysis: Integrating advanced TLS client fingerprint emulation to analyze modern anti-bot detection (Datadome).
  • Goal: Reduce memory footprint and handle concurrent requests efficiently.

Tech: Go, tls-client, Docker


Engineering Interests

  • Migration Strategies: Refactoring legacy Python codebases to Go for performance.
  • Network Protocol Analysis: Understanding TLS handshakes and browser fingerprinting.
  • Distributed Systems: Designing scalable scrapers and backend services.
