This demanded complex techniques and advanced skills, including Man-in-the-middle attack, Reverse Engineering, Fingerprint Masking, and Breaking of Certificate Pinning in Android Apps.- [Migration to a Microsservice] The bank account reconciliation module presented significant bugs, the system was a giant monolithic structure running on an outdated Java version. Collaborating with another back-end partner, we took the initiative to extract this module as a microservice. The project proved to be successful, resulting in a seamless migration without any critical bugs in the subsequent months. We observed approximately 5,000 users per day utilizing this feature.
