About Eashwar Madhavan Perumal

From building full-stack web applications at Walgreens to designing AI features that empower students globally, my passion lies in creating impactful solutions that simplify products and effectively communicate their purpose.I love taking on challenges and exploring unknown territories, as it just means I\'ll learn something new. I strive to understand things at their core, exploring the \"why\" rather than just the implementation details. Career Highlights:* AI for Education: Co-authored a Springer-published research paper on Generative AI in educational platforms, leading the development of features including automated quiz creation, AI-driven feedback, and hashtag generation to support global learners.* Critical Infrastructure: Helped build Walgreens\' COVID-19 vaccination portal, automated credit card form filling for their customer care portal, redesigned the payment portal, and integrated fraud detection systems.* Communication Innovation: Integrated Slack APIs into learning platforms, resulting in a 30% increase in student engagement. Current Focus:* Advancing Large Language Model (LLM) applications in education with RAG models, leveraging API integration knowledge from Walgreens and AI expertise from my master\'s at Purdue and Cyberlabs* Building fault-tolerant, scalable systems using technologies like Temporal.io* Designing AI assistants that deliver power while maintaining an intuitive user experience, with careful attention to accessibility (WCAG), comprehensive testing, and performance optimization🤝 Connect With MeI would love to be considered for Full Stack Developer roles. As a frontend developer, I value user experience (simplicity, accessibility, color contrast) and browser compatibility above everything else. I believe UI is more than just a flashy interface for users to marvel at. On the backend side, I focus on building systems prepared for the worst kinds of server overloads, having experienced numerous user penetration attacks.I\'d love to connect if you:* Build products that improve life for millions* Want to exchange ideas about Generative AI, system architecture, web development or product strategyContact: e••••••••@gmail.com | 31••••••57 Technical Expertise:* Frontend: Angular (v16+), ReactJS, TypeScript, RxJS, Signals, AG Grid* Backend: Java, Spring Boot, Node.js, REST APIs, Express.js, GraphQL* DevOps & Infrastructure: Docker, AWS (EC2, S3, Lambda), CI/CD pipelines (Jenkins, GitHub Actions)* Architecture: Microservices, API gateway integrations, modular monorepos, JWT/OAuth2
