Delegating Repetitive Data Processing Code Migration to a Coding Agent

The author reports that Nubank delegated repetitive data processing code migration tasks to Devin and shared the process of reviewing the resulting changes.

Devin

How it works

  1. The author prepared the target repository, migration criteria, and example changes, then provided these to the coding agent.
  2. The author describes how Devin performed modifications based on the existing code and migration instructions, and submitted the changes for review.

Results

The author reports that the Nubank engineering team delegated repetitive code migration tasks to Devin and published their experience of having humans review the changes.

Notes

This is a usage report published by the Nubank engineering team. The internal code and productivity figures were not independently reproduced.

Example prompt · Devin

Goal: Delegate repetitive data processing code migration to a coding agent.

Input & Environment: [Test repository], [Migration criteria], [Reference change], [Verification command].

Reference original: https://building.nubank.com/enhancing-engineering-workflows-with-ai-a-real-world-experience/

Based on the published workflow, prepare an implementation or work procedure that can be followed in a test environment. Do not guess at internal code or settings not disclosed in the original; if alternative connections are needed, please indicate so.

Required connections and materials: Prepare the target repository, migration criteria, and example changes, and provide them to the coding agent.

Agent actions to implement: Describe the process where Devin performs modifications based on the existing code and migration instructions, and submits the changes for review.

Scope of actions: This is a usage report published by the Nubank engineering team. The internal code and productivity figures were not independently reproduced.

The deliverable is a set of code migration changes that can be reviewed. Please also organize the necessary setup steps and actual execution method. After checking the results returned by the tool, choose the next task, and separately note any materials that could not be accessed or tasks that were not executed.

Verification: Compare the results for the same input before and after migration, and check that code outside the migration target was not modified. Clearly show the input used for verification, the actual output, and any items not yet confirmed.
