$70.00/hr
๐ค More than 5y experience in Python, ML and data science in academia and industry, coupled with a commitment to staying up-to-date with latest developments
๐ฏ Convinced that comprehensive communication is key to ideally complete your project, just as delivering clean, well-documented code is for ensuring its longevity
๐ก PhD in machine learning for cybersecurity, so I can build your ML stack and ensure its secure deployment
I love working on challenging tasks and deploying ML methods in interesting new applications. My broad interest in ML techniques allows me to choose the right methods for any task and my mathematical understanding allows me to put ideas from cutting-edge research into practice. From designing your custom neural networks over tuning them with XAI techniques to ensuring its ideal deployment, I am eager to do it for you.
