The Transiting Exoplanet Survey Satellite (TESS) produces a series of large field-of-view images with a size of 96x24 degress using a cadence of 10 minutes. Even when these field-of-views do not cover directly the ecliptic, thousands of asteroids are available for good quality photometry on a monthly basis. In this poster, we display the structure of the multi-stage pipeline designed to extract precise and accurate photometry from asteroids in an effective manner. The corresponding technical aspects include but not limited to the layout of the backend storage system, staging storages, data product indexing, memory utilization, metadata handling, intermediate products for shift & stack and efficient object querying implementation via SQL. Outputs of these pipeline stages are employed many presentations of this conference as perts of the early second data release.
