Backend developer and data pipeline builder working on user data preprocessing, identity validation, and cleaning machine learning datasets. I design automated microservices to verify contact lists, prevent fake signups, and maintain clean database records. A frequent challenge in onboarding workflows is verifying user identity reliably—specifically how to check gmail availability and check username gmail exist before running batch verification tasks. I focus on lightweight REST APIs that handle syntax checks, MX lookup, and real-time inbox verification. My current projects center on API architecture, developer documentation, and scalable tooling for data hygiene across engineering teams.
