About Haswin Raj

Hey! I’m Haswin I'm a Software Engineer at Zoho Corporation, where I work on Zoho Payroll—a cloud-based SaaS solution that streamlines payroll processing through automation, compliance support, and intuitive employee management tools. With 4+ years of professional experience, I specialize in building scalable, maintainable software systems using Java, SQL, JavaScript, and Ember.js. I write clean, modular code grounded in best practices and design patterns, and I’m adept at both back-end architecture (Spring Boot, Hibernate) and front-end development (Ember.js, Webpack, Gradle). I also have hands-on experience working with cloud-based environments, contributing to the deployment, scaling, and performance tuning of production systems in a SaaS context. I have a strong ability to troubleshoot complex legacy systems and diagnose performance issues, such as network latency or intermittent failures, by analyzing logs and system behavior. I focus on writing maintainable, modular code that improves performance and reliability over time, while ensuring systems remain easy to evolve and scale. I've contributed to modernizing critical infrastructure, including decoupling legacy tax modules and building features like the US Paycheck Calculator, all of which helped enhance system modularity, boost user experience, and support customer growth. Lately, I’ve been diving into the world of AI agents in software development—automating code generation, refactoring legacy code, and improving code quality using ML models that detect smells and improve maintainability 🤖. It’s an exciting space with huge potential to transform how we build and ship software. Always happy to connect with fellow builders, share ideas, or explore collaborations around clean code, cloud-native architecture, AI in dev workflows, or scalable product development. Let’s talk!
