I am passionate about solving complex data problems. As software and data engineer in Japan’s largest telecommunication company I developed a data platform and also learned about cultural and language barrier. This experience have equipped me with excellent technical and communication skills and ability to collaborate with multiple stakeholders. I have worked in data project which involved data migration, anomaly detection, data visualization, Data Warehouse design and ETL.

    Software Engineer (Data)

    • Data Engineering

      • Contributed to the development and maintenance of the data analysis platform which collected and analyzed data from various internal departments. Designed system architecture of core components of the platform such as compute SQL engine Trino, storage HDFS, authentication workflow and Hadoop ecosystem.
      • Collaborated with data analysis team to improve performance of BI dashboards by tuning queries to retrieve data and by improving underlying physical schema.
      • Developed data pipeline to ingest the network traffic flow data from Apache Kafka to HDFS using Pyspark. This pipeline processed over million records per second and was used for real time anomaly detection to mitigate DDoS attacks.
      • Integrated SQL engine Trino with other internal data platform components such as BI tools, authentication systems and data warehouse tools. Developed custom connectors for Trino using Java and contributed to open source community.
      • Developed YouTube playback statistics data collector tool using Java, Docker, and JavaScript which collected run time statistics of YouTube playback from over 1000 nodes to analyze and compare the end-user Quality of Experience of the Internet over QUIC protocol vs HTTP. Collected and analyzed data from over 1000 nodes using python data visualization with plotly. Presented research work at ACM CoNEXT 2018, Greece
    • Software Engineering

      • Developed data catalog metadata platform using ReactJS to increase the productivity of the team by providing features such as advanced search for Japanese text, table search, schema information, and metadata from over 10 different internal systems and tools.
      • Developed JP-EN and EN-JP translation feature and Furigana(reading in Hiragana for Japanese Kanji) in the open source markdown documentation tool called CodiMD using DeepL API, JavaScript, and nodejs. This feature enhanced the communication and collaboration between non-Japanese speaking engineers and Japanese engineers
      • Presented NTT Communication’s Trino usage and architecture design at Trino Japan Virtual Meetup 2021
      • Trained new team members and helped them to understand the overall architecture of the data platform. Created useful tutorials and guides which improved team productivity.
