Feuille de temps aims to provide non-profit organizations and small businesses with an efficient tool for managing work hours. Our goal is to simplify tracking of work hours, leave, and overtime, while generating accurate reports for payroll and project management. We strive to automate calculations and reminders, thereby facilitating human resources management in these sectors.

We believe in delivering products that are built for the people using them, instead of asking people to change for the products. I founded Aynils in an aim to translate business needs into technical solutions for organizations that do not always have the time or specific skills to do these processes internally. • Database Management We define and optimize the storage for your critical information (customer contacts, employees, time tracking, expenses, etc.), e.g., data access definition or local versus cloud data storage implementation. • Data Synchronization We optimize or create flows between your different data sources (Google Drive, Spreadsheets, CRM, Mailchimp, Slack, etc.) to remove the hassle of keeping all these sources up to date, e.g., contact synchronization between an Excel spreadsheet and your Mailchimp distribution list. • Analysis and Consulting We analyze your operational needs and elicit the precise requirements for new IT services. We conduct a research of the market and help you choose the best provider, e.g., requirement definition and provider selection to build a new website or functionality analysis and selection of bookkeeping software. • Project Management We coordinate with the stakeholders and provide regular reports to ensure that every step of the new service delivery is under control. • Web Applications We develop customized web applications to satisfy your exact business needs, e.g., volunteer management platform creation or custom time-tracking app development.

• Built the REST API consumed by our front end, our customers, and the Zapier integration. I implemented the rate-limiting and authentication (OAuth2 via JWT token). • Refactored the whole codebase to make it PEP compliant. I added type hints and docstrings to speed up further developments and avoid Type Errors at runtime. • Mentored junior developers on both career development and technical skills. We do pair-coding, whenever I can help to implement or debug new front-end features. • Integrated multiple external data sources into our platform. Microsoft 365, Microsoft Teams, Slack, GitHub, Bitbucket, Atlassian, Zapier. I managed the API integration and transformed the data to integrate into our model. • Migrated our import routines to Google Cloud Functions. Leveraging Google publisher-subscriber queue, I automated the import from all our external sources to provide always up-to-date data to our users. • Automated our DevOps process for app deployment by using Bitbucket pipelines for CI/CD. • Defined the data model for new types of data and insights. In our environment, links between different entities like people, skills, companies, and projects are crucial.

Opisense is an intelligent and integrated data toolbox that enables the storage and processing of energy, environmental and operational data. Opisense is a toolbox that leverages insights from facilities, infrastructures, and equipment data using your very own data analytics mechanisms. Managing many simultaneous data integration projects, I ensured excellence throughout the projects from pre-sales to post-delivery support. • Modelized the energy performance protocol IPMVP in R and applied it to electric energy consumption data from EDF to set energy savings targets up to 35 % for their customers. • Decoded binary payloads and integrated 80 measurements received from each electricity meter, via a LoRaWAN network in Vietnam to monitor and reduce energy consumption in industrial parks. • Developed a standard Python client to allow developers to interact with Opinum's Opisense API: opisense-client. • Integrated data from 20 different sources about the energy market, production, and usage in Europe to enable Eoly to optimize their energy trading activities. • Wrote the customer online documentation: docs.opinum.com. This documentation explains to non-technical users how to easily use Opisense platform. • Managed the first phase of the EasyMONITORING Project for Total. Integrated data from different legacy systems and made it available through APIs enabling them to build a customer energy analytics portal on top of it.

After having successfully led the implementation of the first phase of easyMONITORING, their customer energy analytics portal, Total hired me for a consulting mission to plan the implementation of the second phase of this project. • Conducted customers interviews to get insights on the actual product and the planned developments. • Gathered and documented the business requirements from the Change and Transformation team. • Coordinated communication between the management, the development team and the external customers. • Wrote user stories to fill the backlog for the developments following the Agile methodology.
