Charles was my director of data science, and was responsible for advancing our machine learning based NLP system.

He demonstrated the ability to build an effective team consisting of data scientists, full-stack developers, and DevOps engineers. Charles also demonstrated the ability to lead a team to build enterprise-level backend infrastructure and to deliver high-quality output for customers.

Charles is dedicated and highly competent in his field; he is beloved by his team; he excelled at product ownership through his interactions with our customers.

I would be very happy to work on future ventures partnering up with Charles again.

Charles worked as a part-time data science consultant for Insidetracker over the course of 10 months. We are looking to expand our nutrition and fitness recommendation capabilities by using big data and giving evidence-based recommendations that we can show to our users in real-time.

Charles helped build various proofs of concepts with that purpose in mind. He was able to demonstrate various correlations and anomalies in the data, and how we could model these discoveries to give our users tips that positively impact their wellbeing.

Charles comes with lots of domain expertise in personalized nutrition, as well as the ability to demonstrate points through hands-on coding and statistical modeling.

It was a pleasure working with him.

Charles' work was critical to supporting vaccine pharmacovigilance activities, employing his Python and data science skills to help contextualize safety signals during the global rollout.

Given the scale of the need and the size of the incoming data, the project was one of the most impactful I've seen in my career.

I had the absolute pleasure of working with Charles at iQuartic. We worked on developing an NLP engine and enhancing the existing Optical Character Recognition pipeline. I relied heavily on him, not just for his technical contributions but also for his thought partnership in designing and solving various complex problems. He laid a strong emphasis on maintaining employees' satisfaction along with prioritizing the company's work.

He has an exceptional ability to communicate technical claims to non-technical audiences and served as a critical bridge between the research and operations teams.

Other than his sharp technical skills, he helped the teams on the management side as well. He's respectful, smart, and a wonderful team player - I very much look forward to working with him again in the future!

I had the distinct privilege to work under his direct supervision as an NLP Engineer when Charles was employed as the Director of Data Science at iQuartic. I can attest to his skills, both as a manager and as an engineer.

When I joined iQuartic, Charles provided guidance to me for understanding the product. He always made sure that I had the necessary tools and support for getting my tasks done. It is under his tutelage I had the freedom and flexibility to look for creative solutions, which is how I learned to repurpose and implement various state-of-the-art machine learning and deep-learning algorithms directly into our product. He was always available whenever we needed his guidance, and my colleagues and I are grateful for the care and knowledge that Charles bestowed on us.

Moreover, Charles demonstrated excellent people-management skills, leadership abilities, creative thinking and attention to detail. It was his managerial skills and innovative encouragement that has led to an impressive growth of our team and enabled us to deliver cutting-edge solutions while following best practices in software development and engineering. He is able to assign, delegate, and solve engineering problems himself because of his copious experience in the industry. He is a source of motivation to us - his employees. In addition to his stellar managerial skills, he is also an active listener, and worked with us on our feedback.

I believe Charles would be an asset to any organization, and I can recommend him without a moment's hesitation.

Really smart guy with a clear mind in his head. Always give me the best advice at work!

He is always very helpful. Always 100% dedicated to his job! As a manager, he taught me how to grow up from the new grad to a proper full stack developer and provide all kinds of support he could offer. Whomever gets Charles as their manager will be so grateful that they can learn tons of things from him.

Efficiency seems to be Charles’s biggest drive and thus his strength: his dedication to ‘not waste anyone’s time’ as he puts it, and his high standards in terms of software development makes him as efficient as he is rigorous.

As a manager, Charles expected me to meet his standards. As a mentor, he taught me how to meet them. During my time working for him, he was able to play both roles equally and his support made our work as efficient and robust as it could be.

Anyone would be lucky to have Charles as a manager, a person that is both motivating and fun, both professional and friendly, making it a pleasure not only to work for him, but also to get to know him.

Charles is a true leader and gifted mentor, who's not only interested in the company's bottom line, but also in his employees' professional growth! As a manager, Charles already has the essential characteristics: smart and analytic, fast and responsive, intelligent risk-taking, and a real team player.

He knows how to bring the best out of the members of his team, by inspiring and mentoring them.

I have been so lucky to have worked with Charles, where I learned a lot from him!
