Hi, I’m Sadeesha.

I’m a Product Support Engineer specializing in SaaS applications, API troubleshooting, and customer success. I work at the intersection of technology and user experience—helping businesses solve complex technical issues while ensuring their customers have a seamless experience.

Currently at PetDesk, I handle L1/L2 application support, diagnose API failures, and resolve integration issues across platforms like Vetstoria and various Practice Management Systems. My role involves deep troubleshooting, cross-team collaboration, and turning technical problems into reliable solutions.

Before this, I built a strong foundation in customer operations and process improvement at HSBC, where I managed high-volume support environments, trained teams, and contributed to service optimization initiatives.

Beyond my full-time role, I’ve worked as an independent API tester—evaluating real-world performance, benchmarking systems, and providing actionable insights to improve product quality.

I also have a background in frontend development, with hands-on experience in React, JavaScript, and responsive web design—giving me a well-rounded understanding of both user-facing and backend systems.

What I bring:

• SaaS & Application Support (L1/L2)
• API Troubleshooting & Testing
• Customer-Centric Problem Solving
• Cross-functional Collaboration
• Process Improvement & Optimization

I’m passionate about solving problems, improving systems, and creating better user experiences through technology.

Let’s connect.
