Over nine months, this developer enhanced the KotatsuApp/kotatsu-parsers repository by building and maintaining a suite of robust web scrapers and data parsers for manga aggregation. They engineered features such as dynamic tag retrieval, author search, and configurable image quality, while also addressing API rate limiting and domain changes to ensure reliable data ingestion. Their technical approach combined Kotlin and Java with web scraping, backend development, and CI/CD automation, emphasizing maintainability and resilience to site updates. Through careful code refactoring, exception handling, and build optimization, they improved data accuracy, reduced manual maintenance, and accelerated onboarding of new content sources.
