Colleagues describe him as "During my first internship at LinkedIn, I had the pleasure of working with Jason as my mentor. Jason was a perfect mentor: he instilled in me great engineering practices and techniques while fostering my creativity and eagerness to find new ways to solve problems. Additionally, Jason is hard-working when he needs to be, and always incredibly helpful. I highly recommend Jason for his skills as an engineer, effectiveness as a mentor and co-worker, and an expert at foosball.", "Jason is a great engineer. I worked with Jason for almost a year, and it was an absolute pleasure. He was always enthusiastic and super dependable. I loved how he was forever keen on learning and looking for newer better ways of doing things. He was very proactive and self-motivated, and an excellent team player. I remember we used to have some interesting design and code discussions. Not to mention that he's super fun, and it was great having him around!", and "Jason interned in the Data Services team at Linkedin and later joined us back as a full time Software Engineer on the Member Segmentation and Targeting project that we were working on.Phase 1 of the project was already rolled out when he joined; it did not take him long to come up to speed with various technologies and tools (Hadoop,Pig,Hive,Azkaban,etc) and start contributing towards key pieces of the system.I mentored him for a brief while and can vouch for his ability to execute complex tasks with ease. He has attention to detail, an appetite to learn and a reputation of delivering quality code.He brought a refreshing mix of passion, thoroughness and positivity to the projects he worked on. He would be an asset to any organization and I would gladly work with him again!"

Phd CandidateUniversity Of California, Los Angeles Sep 2016 - Jun 2022Los Angeles, Ca, UsMy research focuses on improving developer experiences with Big Data systems, with an emphasis on performance and correctness debugging. My prior works investigate how to enhance performance debugging for computation skew in Apache Spark and improve data provenance precision in dataflow applications through a combination of taint analysis and influence-based aggregation functions. More recently I have explored techniques which leverage targeted fuzz testing of individual user-defined functions in tandem with skew-inspired mutation operators to generate workloads which reproduce specified performance symptoms, particularly in scenarios where no suitable datasets are available. -
