Professional Overview
DearMy passion for programming and expertise in implementing machine learning models would make me an excellent addition to your team. I am excited to apply for this position at your company.At my inaugural role at ShipBob, as a software developer, I played a pivotal part in enriching various aspects of the project. My contributions spanned across enhancing the e-commerce site's search functionalities through strategic integration with Algolia, alongside developing robust RESTful APIs and meticulously designing database schemas.As the Machine Learning Developer at Mercari, I have excelled at designing and developing machine learning and deep learning projects. By implementing several machine learning algorithms and technologies in the recommender system of our e-commerce processes, we were able to analyze our customers’ behavior and improve UX. Additionally, I participated in the development of Mercari AI Assist using LLMs and introduced AI into the deferred payment service. As a result, the development team redesigned our website, resulting in a significant increase in the number of purchases made this month and contributing to making this company one of the biggest e-commerce companies globally.Then, at Tredence Company, I have participated in many projects such as LAG chatbot development with LangChain, resume matching and analysis using LCEL and FAISS vector db, toilet training assistant, and hotel recommender systems with Open AI and Redis for several industries including finance, healthcare, e-commerce, tourism, and business management. In some projects, I worked as a MLOps Engineer so I built CI/CD/CT pipeline using Kubeflow on Kubernetes Cluster or Vertex AI on GCP or SageMaker on AWS for the whole ML workflow. I used A/B testing and some providers such as Grafana or Prometheus for monitoring and evaluating the AI system in a production environment. I also built the data pipeline using open source frameworks and platforms such as Aparch Airflow, Spark, Kafka, Hadoop and so on. I played an important role in solving difficulties with collaboration within multi-functional teams.I’m confident my skills and experience can help your company reach its goals. I would be happy to further discuss my interest in the position. Please feel free to contact me anytime for an interview.Thank you for your consideration.Yuji Oshima
