PROFILE
Bojan Kopunovic
During December 2024, Boris Kopunovic enhanced the jumperexchange/jumper-exchange repository by stabilizing end-to-end testing and optimizing CI pipelines. He integrated Synpress for MetaMask connectivity, implemented deterministic dependency management with Yarn.lock, and introduced sharded test execution to accelerate feedback cycles. Boris improved test reliability and CI throughput by refining cache management, tuning Playwright and CI YAML configurations, and enabling headless Xvfb-based testing. Working primarily with JavaScript, TypeScript, and YAML, he addressed both feature delivery and bug resolution, focusing on robust automation and maintainability. His work demonstrated depth in asynchronous programming, DevOps, and test automation, resulting in more reliable production deployments.

60 Commits • 10 Features
Dec 1, 2024December 2024 focused on stabilizing end-to-end testing, increasing CI throughput, and delivering reliable wallet flows in Jumper. Key features delivered include Synpress integration for Metamask connectivity in Jumper app, deterministic builds via Yarn.lock, and sharded test execution. Major improvements in test reliability and CI stability were achieved through Synpress cache enhancements, cache-building optimizations, and comprehensive CI/Playwright pipeline hardening (local env setup, server reuse, worker and timeout tuning, plus headless Xvfb-based end-to-end testing). These efforts collectively reduced flaky tests, accelerated feedback loops, and improved production readiness for new features. Technologies demonstrated include Synpress, Playwright, Xvfb, caching strategies, CI YAML tuning, and parallel test execution.
