Hi, I'm Vyn πŸ‘‹

Engineering Undergrad ('22–'26) | AI/ML Engineer & Full-Stack Developer

I bridge the gap between complex machine learning research and high-performance production systems. My focus is on building scalable, data-driven tools using Python, Go, and FastAPI.

⚑ Performance Highlights

  • High-Concurrency Systems: Engineered a Go crawler capable of processing 10k+ URLs in <5 seconds.
  • Scalable AI Pipelines: Built a FastAPI/React ecosystem that parses and analyzes 50MB+ PDFs in <10 seconds.
  • Anomaly Detection: Developed a GMM-based fraud model achieving a 0.93 ROC-AUC on 280k+ transactions.

Current Interests: NLP & LLM Orchestration, Computer Vision, and Medical Imaging.

🌟 Beyond the Code

I’m driven by the challenge of turning complex research into production-ready tools. I build with a global mindset and a passion for scalable innovation.

Off-duty? I’m your unofficial フィンランド観光倧使. Let’s venture into the "code wilderness" and build something impactful!
