## Work Experience
### Software Engineer at Databricks @ Databricks
Jan 2024 – Present | Mountain View, California, United States
Spark Structured Streaming

### Teaching Assistant 15418 Parallel Computer Architecture @ Carnegie Mellon University School of Computer Science
Jan 2023 – Present | Pittsburgh, Pennsylvania, United States
- Developed course project optimizing code under message passing model using OpenMPI.
- Regularly held office hour to help students debug/profile their codes and offer additional conceptual reviews.

### Software Engineer Intern @ Google
Jan 2023 – Jan 2023 | Sunnyvale, California, United States
- Developed a service that supports same container task migration for Borg jobs (with Borg public APIs, Spanner DB and Queue, Scaffolding, gMock for testing).
- The service supported Borg job upgrade without rescheduling outside the container, thereby reducing downtime and saving resources when new packages need to be installed or updated.
- Scaled out and improved efficiency by having multiple processors of state machine to support concurrent job updates.

### Research Assistant at CAOS Lab @ Carnegie Mellon University School of Computer Science
Jan 2023 – Jan 2023 | Pittsburgh, Pennsylvania, United States
- Worked with Prof. Dimitrios on benchmark the performance increase of hugepage usage in virtual machine.
- Benchmarked MEMCACHED workload in different settings of hugepage usages for both hosts and guests.
- Found out hugepage benefits might come from reduced page walk cycles more than TLB misses, contrary to previous expectation.

### Teaching Assistant 15445 Databasse @ Carnegie Mellon University School of Computer Science
Jan 2023 – Jan 2023 | Pittsburgh, Pennsylvania, United States
- Developed course projects (Bustub Database), designed two phase locking protocols with different
isolation level and autograder testcases.
- Led weekly office hours to help students debug and additional office hours to clarify complex database
concepts

### Research Assistant at Living Edge Lab @ Carnegie Mellon University School of Computer Science
Jan 2022 – Jan 2022 | Pittsburgh, Pennsylvania, United States
- Worked with Prof. Satya to support cloud native application to discover nearby cloudlets for low-latency
edge computation.
- Experimented with linux network namespace to set up Wireguard VPN as a user without root privilege
for message encryption

### STEP Intern @ Google
Jan 2022 – Jan 2022 | Mountain View, California, United States
- Developed a handy tool to automatically help clients select more efficient data retrieval method.
- Constructed a data processing pipeline (Flume) that scales the above tool to support clients with hundreds of millions of rows in a table.
- Identified all clients capable of performance improvement via the above pipeline; quantified the possible loading time reduction (75%).

### Research Assistant @ Carnegie Mellon University
Jan 2021 – Jan 2022 | Pittsburgh, Pennsylvania, United States
- Constructed a data processing pipeline (python and pandas) to transform noisy raw data from csv files into clean training, testing datasets for machine learning algorithm 
- Defined metrics and quantified the effects of promotions on sales trends; distinguished promotions with large effects; generated an additional promotion-effect feature; compared prediction accuracy with and without that feature
- Applied k-means clustering, grouping similar customers, to discover statistics patterns within the same cluster
- Facilitated more accurate prediction of future sales based on real-time signals collected as a result
