Sylwia Laskowska discusses challenges of managing legacy frontend code and migration processes. Legacy tech aging faster than business needs leads to legacy systems. Migration strategies include Big Bang and incremental approaches depending on project constraints. Real-life migration stories highlight importance of thorough planning. Incremental migration using strangler pattern allows continuous feature development alongside legacy system phase-out. Strangler pattern advantages include easy rollbacks with feature flags. Challenges in migration involve sacrificing story points and developer discontent. Effective migration planning emphasizes testing, continuous planning, and the consequences of inaction.

AI dashboard utilization challenges include lack of clear metrics for effectiveness and low adoption rates. Companies struggle with AI implementation leading to delivery improvements and financial gains. AI transformation hurdles stem from a focus on fluency over workflow redesign. Achieving true AI integration requires deep integration for transformative change. Organizational challenges in AI involve balancing code production with product outcomes. Key steps for AI transformation include measuring real changes in production and prioritizing killing ineffective pilots. Managing cloud costs and addressing unused resources are key concerns. Measuring AI impact on teams, business, people growth, and skill development is crucial for successful implementation.

Shubham, a senior software engineer at Headout, discusses challenges when React meets real-time systems while working on an internal tool for audio doors.
