  • Identify and resolve performance bottlenecks in high-load production environments.
  • Work directly with Frontend (React/Vue) and Product teams to design seamless API contracts and data flows.
  • Lead by example through thorough code reviews and sharing best practices on SOLID and DRY principles.
  • Own your deployment pipeline, working with Docker and Azure DevOps/GitHub Actions to ensure smooth releases.
