Alexandre Kitanidis

Developed and deployed APIs for different usecases Implemented real-time event processing with Flink for streaming solutions Industrialized data science algorithms using SageMaker and Airflow Improved Snowflake RBAC and IaC management Contributed to the architectural design of various projects Worked on monitoring and alerting using DataDog for various projects Refactored CI pipelines to improve Docker images lifecycle Maintained Snowflake data lake with near real-time and batch ingestions

Maintaining and development of the company’s data platform, working in a team of several data engineers with an agile workflow: - Implementation, orchestration and improvement of data pipelines - Implementation of a near real-time data pipeline - Connection of data pipelines to external APIs - Work on cost saving solutions for S3 and Snowflake - Implementation of DBT for SQL transformations in data warehouse - Migration of Airflow hosting solution to Kubernetes - Industrialization of data science workflows - Support to the BI and data analytics teams for troubleshooting of data related issue

Work on the full implementation of a data architecture for a new factory, from the definition of all the tables needed to be created in our cloud warehouse (on Snowflake) with an ELT tool (Matillion) to the different visualization tools that had to be created with PowerBI from these tables. Deployment of connected sensors in our factories, optimization of their data transmission to a SQL database connected to our cloud solution. Improvement of the tools to visualize and get alerts from the sensors data both with PowerBI and Google Apps Scripts. Improvement of an image analysis tool for larvae counting in an existing factory and development of a graphical user interface for the workers to use the tool. Development of several image and video analysis tools for different R&D projects. Innovafeed is a biotech company that produces a new source of protein from insect rearing for animal feed, more specifically for aquaculture.

Project of identification of genetic markers from tumor classification on gene expression data : - Reduction of dimensionality through PCA applied to genes expression - Representation of the genetic data as heatmaps - Binary classification (with or without tumors) with a CNN - Work on the interpretability of the classification with gradCAM algorithm to identify genetic markers

Engineering internship in the hospital of Nantes: - help in the management process of automation of different tasks in the hospital, redaction of meeting reports, following of the evolution of different teams and reports on the project's progess compared to the schedule - realization of a study involving singal processing and statistical analysis on patients having cardiac pathologies
