9years at Ipsos

At Ipsos, I work on complex survey development — scripting logic, metadata mapping, respondent flows, quota systems, and automation-heavy workflows.

This gave me strong experience with:

  • messy real-world business logic
  • edge cases and data validation
  • debugging event-based systems
  • stakeholder requirements
  • production-critical workflows
