Experience

  • Hidroconsulting SAS

    IT Analyst · Hidroconsulting SAS

    I designed and developed the company’s website using TypeScript with Next.js, handling both frontend and backend, and integrating Neon PostgreSQL and Tailwind CSS. I implemented various services, including email sending with Brevo, an MDX-based blog powered by Notion API, a quotation system, and a commercial page with dynamic filtering and nested layouts. The generated quotations and customer inquiries (PQRS) are automatically sent to the company’s commercial email. Additionally, I developed an application with Google Apps Script to automate quotations using templates in Google Sheets, with storage in Drive. I led deployments and set up CI/CD pipelines for the frontend, managing repository changes with Git and establishing best practices for version control within the company.

    I developed and designed automated emails using HTML and CSS for mass mailing campaigns, utilizing the Brevo API. I identified, cleaned, and organized unstructured data, optimizing its use in automated email marketing campaigns. I configured dynamic elements, such as personalized names and titles in emails, to enhance engagement and personalization. I monitored campaign performance and created BI reports to assess their impact and adjust future strategies. Additionally, I developed scripts in Node.js for the mass generation of personalized diplomas, automating the integration of dynamic data into email marketing campaigns.
