Quant Engineer

• May 2017 - Jun 2019

As a Quant Engineer, I address real world problems with advanced statistical concepts. Using mathematical models I design prototypes, iterate over them, and propose scalable solutions. I work in tight collaboration with the development team to productize selected algorithms. Key successes: • Prototype to viable product development • Test-driven development • Leading technical workshops for clients and developers • Supervising interns As a Quant Engineer, I address real world problems with advanced statistical concepts.
