Current Positions

  • Backend Python Developer | Django and DRF at Deep Opinion - Groupe Ifop

Who am I?

I am a calm, structured person who draws energy from continuous learning and purposeful work. My strength lies in grasping new concepts quickly and translating them into reliable, well-considered solutions — an approach that defines my work as a backend developer focused on Python and Django.

My path into software development was not a straight line — it led through chemistry, customer service, and ultimately a deliberate career change. Those experiences gave me something that can't be taught in a classroom: perseverance, adaptability, and a genuine understanding of what it means to take ownership.

I hold myself to high standards, particularly in software development. Clean architecture and careful implementation are not ends in themselves — they are the difference between code that works and code that lasts. That same commitment to quality shapes how I communicate: I value clarity, directness, and transparency, especially when requirements are shifting.

I enjoy working both in teams and independently. What matters to me in either context is reliability — that people know where they stand, and that agreements are kept.

As a German native who works in English and lives in French, I bring not only technical skills but also cultural flexibility — something I experience as a genuine asset in international teams every day.

Achievements

  • Completed OpenClassrooms Bachelor-level program 5 months ahead of schedule

    Finished a 24-month developer training program in 19 months, conducted entirely in French — a non-native language.

  • Delivered production-ready code within the first few months

    Joined Deep Opinion with minimal onboarding and contributed functional, production-ready code within the first four months.

  • Designed the complete database architecture for all company projects

    Defined every model, relationship, and schema across multiple Django applications, with no existing blueprint to follow.

  • Implemented a custom MFA authentication system independently

    Researched, chose the approach, and built a custom multi-factor authentication system — without prior experience with MFA and without external guidance.

  • Introduced Sentry as the team's error monitoring tool

    Identified the need, proposed the integration, and implemented Sentry across projects — a tool the team had not used before.

  • Migrated and rebuilt 2 production applications from Flask to Django

    Took over Flask projects, and redesigned the full application structure, and models from scratch.

  • Sole Backend Developer at Deep Opinion (since Jan 2025)

    Responsible for the entire backend architecture of a consultancy serving major clients — as the only backend developer, independently owning all technical decisions from database design to deployment.
