Harold Sumbrana

I am a versatile software developer with expertise in Flutter, AWS, Salesforce, and web development. I build secure, high-performance cross-platform mobile apps using Flutter and Dart, integrating them with serverless AWS backends through Lambda, API Gateway, and S3. My experience includes developing responsive web applications with modern frameworks, implementing RESTful APIs, and optimizing database performance.

I have worked extensively with Salesforce CRM, customizing objects, automating workflows, and integrating APIs to ensure smooth communication between systems. Skilled in Agile environments, I collaborate closely with cross-functional teams to deliver user-focused solutions on time.

With strong problem-solving skills and attention to detail, I aim to create impactful applications—whether mobile, web, or cloud-based—that improve user experience and business efficiency. I am eager to bring my combined mobile, web, and cloud expertise to a forward-thinking organization.
