Available to hire
I’m Adrian Apostol, a senior full-stack developer from Romania with 8+ years building scalable, high-traffic web applications, APIs, and real-time systems. I work across PHP (Laravel/CodeIgniter/Yii), JavaScript (React/Vue/Node), and modern integrations like Elasticsearch, GraphQL, Docker, and cloud services—always with a strong focus on performance, reliability, and business impact.
Over the years I’ve contributed to enterprise and product environments, from event ticket reselling with real-time buyer/seller interactions to multi-tenant compliance-focused platforms for senior care. I’m also comfortable creating cross-platform extensions (Flutter/Dart) and more recent AI-driven experiences, including a hospital patient-visit chatbot flow and an AI kiosk demo for autonomous agent interactions. I’m open to B2B via an SRL in Romania or full-time employment, and I’m flexible for remote or on-site roles.
