I'm Aleksandra Ivankova, a Senior Flutter Engineer based in Novi Sad, Serbia. I bring 4+ years in software development and 3 years specifically in Flutter, focusing on performance optimization, app stabilization, and architecture refactoring for fast-growing startups. I turn laggy, unstable Flutter apps into smooth, scalable, production-ready products by debugging legacy issues, eliminating tech debt, and establishing solid engineering processes. On top of delivering high-performance UI, I have built CI/CD pipelines, re-architected stacks (Riverpod-based), stabilized foreground location tracking, and led cross-functional discovery with backend and product teams to ensure scalable, secure solutions. I'm open to remote work or relocation and enjoy sharing knowledge through documentation and mentoring.…I'm Aleksandra Ivankova, a Senior Flutter Engineer based in Novi Sad, Serbia.
