I am honored to write this letter of recommendation for David Oleksy. I have had the privilege of working closely with him
I met David about a year ago at the American Bar Association’s Artificial Intelligence and Robotics Institute in Santa Clara CA.
David is a very wise young man. I met him at Harvard in 2024. He is not only knowledgeable about information technologies that
I was introduced to David at Harvard in June 2024. We exchanged perspectives on marketing and business growth.






To whomever it may concern,
I wish to recommend David Oleksy as a potential member of your team. I have had the pleasure of working with him on a bioinformatics project called ecoliframalpha, where we modeled the process of translation in E. coli using Python as our coding language, and during our time working together he proved himself to be a person of talent, professionalism and dedication to the work.
From the beginning of our collaboration, David showed that he has a competent understanding of Python syntax, a good understanding of molecular biology modelling, and that he was willing to learn advanced tools and libraries commonly used in bioinformatics, such as Scikit-learn, pandas, and numpy. He contributed robust and efficient code and his project architecture was well-designed and maintainable. He wrote code according to PEP8 best practices—writing clean, well-documented code maintained with version control—and he clearly showed expertise well beyond what is common at his current academic level.
Besides his technical acumen, David proved to have great independent problem-solving skills, analytical thinking and ability to self-direct. He is able to write algorithms and complex projects that fulfill the requirements and he is also able to quickly diagnose issues and propose creative solutions. He implemented the key logic of the entire project without any direction or supervision, and learned the structure and tools for further refinement of the project from our collaboration.
David has strong communication and teamwork skills. He engaged actively in project discussions, provided feedback, and displayed was open constructive criticism. This collaborative mindset is an asset that you definitely want in your organization, and he is always positive and productive in our conversations.
David is deeply motivated, highly disciplined, and truly passionate about computational biology. I am confident he will thrive in an environment that challenges him to innovate, learn, and apply their skills. He is an outstanding candidate for any research group, academic program, or professional organization focused on computational biology or data science.
I am confident in recommending David, and I have no doubt he will be a valuable asset wherever they choose to go next. Should you have any questions or require additional information, please feel free to contact me at rcresb@gmail.com.
Thank you for your consideration.
Sincerely,
Rubén Crespo Blanco, Independent Bioinformatics Developer.
