GetQuanty is the main product I have worked on for many years. I joined as a full-stack developer and progressively took a broader technical role, then a tech lead role. Over the years, I worked on many parts of the platform: Angular frontend, Node.js backend, data workflows, internal tools, backoffice, Chrome extension, integrations, payments and some infrastructure topics.

One of the major areas I contributed to was marketing automation. I developed a large part of the REA campaign system, including the campaign builder and backend logic allowing teams to define multi-step email workflows with delays, conditions and automated actions over time. This work relied on background jobs and orchestration logic using Agenda.

I also designed and implemented a generic native integration architecture for several CRMs. That foundation made it easier to build and extend connectors such as Eloqua, HubSpot, Pipedrive, Sellsy and Divalto. In parallel, I contributed to the company backoffice, to the Chrome extension and to my.clicsight-related work, including Stripe-based payment flows. I also handled infrastructure work when needed, including a MongoDB production migration on GCP.

At Opti-Mix, I worked on several technical projects related to data extraction, price analysis and client delivery workflows. This period was foundational in my career because I worked on both development and operational topics: building new scripts, maintaining existing ones, loading and exporting data, testing websites manually and interacting with client needs.

Among the projects I worked on was xlbscrapper, a Node.js web extraction tool designed to navigate sites efficiently and in parallel. I also contributed to chainreporter, a desktop application used to analyze CSV files and produce interactive reports for quality control before delivery. Another project was xlbwebchangecapturer, a Node.js script used to generate organized screenshots from a predefined list of URLs in order to track design and content changes over time.

This role taught me a lot about handling real-world data workflows and maintaining reliability in systems that interact with external sources.

During my end-of-studies engineering internship at Opti-Mix, I worked on pricing optimization topics in the retail sector. The goal was to integrate an evolutionary algorithm into the company's existing software environment to help optimize pricing strategies for supermarkets.

I worked with the NSGA2 algorithm, a well-known multi-objective evolutionary algorithm, within a Java-based stack using Spring, Smart GWT and Hibernate. This internship gave me my first exposure to real-world software engineering in a professional environment and set the foundation for my later full-time role at the same company.
