PROJECT

Next-Generation ETL Framework for Data Science Team

2022/7-2022/12

  • Goal: 
    1. Design a lightweight ETL python framework enabling data scientists to seamlessly deploy their pandas/SQL processes to airflow in a maintainable format.
    2. Reduce the maintenance and optimization cost of AI projects with integration of customizable data validation, metadata registration, and time/memory-profiling tools. 
    3. Ensure flexibility and extensibility in pandas-like packages (such as CuDF, Polars, PySpark, etc) for future parallelizability, targeting 1000X speedup.
  • Responsibility: Coordinate the design and development of ETL framework components. Give instruction to ETL research intern and provide code review and design guidance for the project participants.
  • Accomplishment: Have wrapped the framework into a workable python package and successfully imported it into two production projects, with ETL business logic automatically rendered on the Airflow UI in an easily traceable way.

Enhance and Maintain House Price and Mortgage Loan API

2022/2-2022/7

  • Responsibility: API Service maintenance, code refactoring, and model performance enhancement for the house-price/mortgage loan automatic appraisal system. 
  • Accomplishment: 
    1. Encrypted API re-routing: 
      • Re-route the internal mortgage API service as an encrypted API service for external client. Understand and implement the RSA/AES double encryption protocol under spec-ambiguous situation by investigating client-side PHP code. 
    2. Code refactor and migration: 
      • Reduce the cognitive complexity of service code from 1000-line-single-file situation by thoroughly understand the business logic and refactoring it into chain-of-command design pattern. 
      •  Design common module with logging mechanism to reduce future maintenance cost. 
      •  Draw and carry out the code migration plan without compromising the 24/7-criteria. 
    3. Re-design of house appraisal model for interpretability:  
      • Coordinate with research institution and business unit to build a business interpretable deep learning model. 
      • Re-design the loss function with regularization term to meet the legal requirements. 
      • Reducing the model inference time by adopting Google’s state-of-the-art nearest neighbor algorithm for referential house searching.
