As a backend developer, I manage Java-based projects using Gradle and Maven for build and maintenance. I build and maintain scalable and reliable web services, and optimize big data search performance with Elasticsearch. In data processing, I use Apache Spark and manage real-time data streams through Apache Kafka.With Apache NiFi, I process data using custom processors and Groovy scripts, and design efficient NiFi flows. My expertise in data crawling includes data retrieval from e-commerce platforms such as Gojek and Tokopedia, to social media such as Facebook and Twitter. In server operations, I manage program scheduling through Crontab and handle web service configuration and deployment with Supervisord, ensuring that services continue to run optimally.

As a freelance backend developer, I build scalable web services with Spring Boot, manage big data using Elasticsearch for fast search, and process large amounts of data with Apache Spark. With Apache Kafka, I handle real-time data streams, both in sending (produce) and receiving (consume) data.
