<tt>pinta</tt>: The uGMRT data processing pipeline for the Indian Pulsar Timing Array

We introduce pinta, a pipeline for reducing the upgraded Giant Metre-wave Radio Telescope (uGMRT) raw pulsar timing data, developed Indian Pulsar Timing Array experiment. provide detailed description of workflow and usage as well its computational performance RFI mitigation characteristics. also discuss novel independent determination relative time offsets between different back-end modes uGMRT interpretation observation frequency settings, their agreement with results obtained from engineering tests. Further, we demonstrate capability pinta to generate data products which can produce high-precision TOAs using PSR J1909-3744 an example. These are crucial performing precision uGMRT.
