Develop features for calculating pastry costs, managing resources, and analyzing profitability, optimizing production processes.
October 2023 - October 2023 (1 month)
Paris, France
🚀 Improvement of Pastry Cost Management Processes: I actively participated in the implementation of innovative solutions to optimize the calculation of production costs for pastry recipes.

📊 Detailed Management of Raw Materials: I implemented features allowing users to enter precise information on their raw materials, including cost per gram or kilogram, sugar content, fat content, as well as the presence of allergens and additives.

👥 Integration of Human Resources: I added the possibility of integrating different production positions (pastry chefs, interns, apprentices, etc.) and defining the associated hourly rates, thus allowing a precise evaluation of the cost of labor.

💰 Tax Management and Financial Analysis: I integrated tax management and implemented financial analysis tools to calculate the production cost of a recipe, taking into account all variables. This approach offers a clear view of the cost price, facilitating decision-making to optimize profits and minimize deficits.

My goal is to provide concrete and effective solutions to help pastry professionals better manage their costs and maximize their profitability.
