During our time together at Corti, Nate evolved remarkably as a data scientist and engineer. His unwavering commitment to growth and quality was evident in his continuous pursuit of new challenges and skills. Nate's collaborative spirit, technical acumen, and eagerness to learn not only enriched our projects but also inspired the entire team. His capacity to adapt and excel make him a standout data scientist and engineer, and I wholeheartedly recommend Nate to any forward-looking team in need of a dedicated problem-solver and team player.

Nate has been working closely with me in the data science team at Corti. His data science and engineering skills are outstanding. It allowed him to quickly become the main contributor to the machine learning team at Corti. His technical skills are especially strong in the domain of data engineering, and data analysis. He is also good at paying attention to the detail of the codes. His thorough code review and documentation as well as his contribution to the continuous integration definitely helped our team a lot to scale faster and made our software more robust! Also, Nate has been contributing a lot to the company not only from the technical aspects but also from the cultural aspect and the product vision. His point of view is not only valuable as an engineer but also as a key stakeholder in the company's product direction. This mindset means a lot to the team and to the company as he considers the way to solve the challenges by not only implementing the software features but also by suggesting the future direction of the product. He is definitely the best data scientist and team player I've ever worked with and it is very lucky to have him on my team. Lastly, he always brings positive energy to the team every day and people love workings with him! Huge recommendation from me both as a team lead and as an engineer!
