Profile bio
About Simon Cho
I am a full-stack engineer with 3 years of experience.In addition to regular feature development, I particularly enjoy identifying areas for optimization as part of my tasks. Witnessing a reduction in memory usage or execution time brings me a great sense of accomplishment.I remember when I first joined, I took the initiative to optimize the MongoDB aggregation pipeline, resulting in a 90% reduction in execution time. This not only surprised my supervisors but also led to my designation as the person responsible for reviewing schemas in the future.Following that, I delved into self-learning schema design patterns, which proved to be especially impactful in enhancing search functionality.
