About

Full Stack Developer building production-ready web applications using Java, Spring Boot, React.js, and AWS and actively integrating Generative AI into real-world products. I'm Sumit Halge, an MCA graduate from MIT Aurangabad with 11+ months of hands-on experience developing end-to-end full stack applications at Paarsh Infotech. I work across the complete development lifecycle — designing secure REST APIs with Spring Boot, building responsive interfaces using React.js and Tailwind CSS, managing MySQL databases, and deploying applications using AWS S3, CloudFront, and GitHub Actions CI/CD pipelines. What differentiates my profile from many developers at my experience level is practical deployment exposure. I don’t just build applications locally — I design, secure, optimize, and deploy them using cloud infrastructure and automated pipelines. My technical stack includes: Backend: Java 17, Spring Boot 3.2, Spring Security, JWT Authentication, REST APIs, JPA/Hibernate, Microservices basics Frontend: React.js 18, JavaScript, Tailwind CSS, HTML5, CSS3 Database: MySQL 8.0 Cloud & DevOps: AWS S3, AWS CloudFront, GitHub Actions, CI/CD Tools: Git, Postman, Swagger, Agile/Scrum workflows Currently Learning: Generative AI, Prompt Engineering, OpenAI & Gemini APIs, RAG-based application integration Projects I’ve worked on include: • Full Stack Web Application deployed using AWS S3 + CloudFront with CI/CD automation • Medicine on Time — health-tech application for medication scheduling and reminders • Personal Portfolio Website — live at: www.sumithalge.work I’m currently open to opportunities as a: Full Stack Developer Software Engineer Java Developer React Developer Technical Support / Production Support Engineer (with development background) I enjoy building scalable applications, learning modern cloud deployment practices, and integrating AI capabilities into full stack systems.
