Top SchoolAngela Čelar is a Senior Software Engineer with 8 years of experience specializing in backend systems, API design, and distributed task processing, currently working on booking processing platforms integrated with Kiwi.com. With a master's in Physics and Computer Science, she brings analytical rigor to building multi-versioned REST APIs, Celery-based pipelines, and high-throughput data workflows that have handled tens of thousands of ad groups per hour. She progressed from junior developer to technical lead, owning migrations (AdWords to Google Ads), architecting multi-queue Celery systems, and implementing async I/O with uvloop for performance-critical services. Her background in teaching introductory programming has honed her patience and ability to translate complex concepts for cross-functional teams, especially marketing partners. Comfortable in cloud-native environments (GCP, PostgreSQL, S3) and partner-facing platforms, she excels at offloading business logic to robust backends that simplify frontend workflows. Colleagues describe her as a pragmatic problem-solver who pairs scientific training with hands-on engineering to drive reliable, scalable integrations.
