ABOUT MUHAMMAD HASSAN

I\'m a Senior Software Engineer with over 5 years of experience building scalable, high-performance web applications. Currently, I work at Straiv GmbH in Stuttgart, where I lead backend development and system integrations that enhance the hotel guest journey — from check-in to payment and access control. I\'ve led initiatives that boosted platform reliability, reduced system latency, and increased customer acquisition by 25%. Previously, I worked at Devsinc, where I transitioned from Associate Software Engineer to a leadership role. There, I delivered tailored e-commerce platforms, improved real-time messaging with Action Cable, and helped cut response times by 10% through efficient API design using Ruby on Rails and GraphQL. I also mentored junior developers, conducted interviews, and led training modules that increased internal knowledge retention by 15%. With hands-on experience across the full development lifecycle — from architecture to deployment — I thrive in fast-paced, product-driven environments. My toolkit includes Ruby on Rails, PostgreSQL, Sidekiq, AWS, GraphQL, and CI/CD practices with GitLab. Outside of work, I\'m an explorer at heart — having visited 3 countries so far — and a passionate badminton player who’s always up for a friendly match.
