Worked on stabilizing the neonlabsorg/neon-tests repository by addressing reliability issues in the test suite. Focused on refining the exclusion logic for modexp-nagydani-5 related test cases within test_precompiled_contracts.py, which reduced flaky failures and improved the determinism of test outcomes. Delivered targeted dependency updates for both production and UI Python packages to enhance compatibility and security. Fixed a bug in test_call_via_send_trx, contributing to more predictable CI feedback. Leveraged skills in Python development, DevOps, and testing to streamline test execution, resulting in faster feedback cycles and increased confidence in continuous integration processes over the course of the month.
