Review company-level records connected to Kai Samejima before choosing the right outreach path.
After graduating from Kyoto University, I started my career at NTT Docomo. I worked in the 5G and IoT Business Division of the corporate sector for 3 years, focusing on service planning and development for the manufacturing industry as well as technical sales both domestically and internationally. Alongside my main responsibilities, I honed my data analysis skills and took on multiple data analysis projects for the manufacturing sector. Later, I moved to the research and development department, joining the in-house development team utilizing AWS for big data infrastructure. There, I worked on developing and operating an ETL system for processing communication control signals collected nationwide in real-time, along with data analytics tasks. My strength lies in having both planning and customer negotiation skills in the business domain and data engineering skills in the engineering domain.京都大学卒業後、NTTドコモに新卒入社。法人事業の5G・IoTビジネス部に配属され、製造業向けのサービス企画及び開発運用、国内外での技術営業を3年間担当。メイン業務の他、業務外で習得したデータ分析スキルを元に、製造業におけるデータ分析プロジェクトを複数受注しデータアナリストとしての実践スキルを磨く。その後、研究開発部門に異動となり、ビッグデータ基盤の内製開発チームに配属。日本全国から大規模に収集される通信制御信号をリアルタイムに処理するETLシステムの開発運用、データアナリティクス業務に従事。ビジネス領域での企画・顧客折衝スキルと、エンジニア領域でのデータエンジニアスキルの両面を持つことが強み。
