Sandhya Gandra

I’m a Full Stack Software Engineer with 5+ years of experience designing, developing, testing, and deploying scalable web applications. I focus on ownership, attention to detail, and clean code—working in Agile environments to deliver reliable systems aligned with client goals and business commitments.

On the backend, I build robust services with PHP/Laravel 8+ and Java Spring Boot, delivering RESTful APIs with middleware, validation, and secure API integrations. I’ve implemented authentication and authorization using OAuth2 and JWT, including role-based access control, and I use Eloquent ORM and query-builder patterns to improve database access and reduce query complexity.

On the frontend, I create responsive, user-focused experiences using React.js, Vue.js, and Angular, along with TypeScript and reusable UI components. I strengthen quality through automated testing—unit, browser, and API validation with PHPUnit, Pest PHP, Laravel Dusk, Playwright, Selenium, JUnit/Mockito, and Cypress—then reinforce releases with CI/CD using GitHub Actions, Jenkins, Docker, Kubernetes, and Terraform.

My impact includes modernizing enterprise banking systems, improving transaction throughput by 25%, and supporting high-volume operations through event-driven processing with Redis caching and Apache Kafka. I also enjoy building pragmatic AI-enabled features, like a GenAI-based exception handler and an internal RAG knowledge search engine using LangChain and LlamaIndex, while providing production support and mentoring teams through strong code reviews.
