Educational platform helping students and young people prepare for real-life topics that schools often do not fully cover

Pro bono engagement to stabilize and modernize the NGO’s educational platform. Designed and implemented GitHub Actions CI/CD pipelines for automated testing, building and deployment. Migrated and upgraded AWS Lightsail infrastructure. Introduced project management and planning processes for a non-technical team. Led vendor evaluation — sourced candidates, conducted interviews, and managed the full platform handover to new contractors. Resulted in improved platform stability, fewer outages, and predictable cost and feature delivery.
