About

Portfolio: https://kumar-harsh.vercel.app I’m a Full Stack Software Engineer with strong foundations in Object-Oriented Programming and Data Structures & Algorithms, and hands-on experience building scalable, production-grade systems. I’ve worked across startup and institutional environments, including Indian Institute of Science (IISc), Bengaluru, where I led end-to-end development of platforms used by 500+ real users, reducing manual operations by up to 90%. I enjoy owning products end-to-end — from backend architecture and APIs to polished, user-facing experiences. Tech I work with: • Frontend: React, Next.js, TypeScript, Tailwind CSS • Backend: Java (Spring Boot, Spring Security), Node.js, REST APIs, WebSockets • Databases: MongoDB, DynamoDB • Cloud & DevOps: AWS (EC2, S3, CloudFront, CloudWatch), Docker, NGINX • Generative AI: LLM-based systems (OpenAI APIs, Google Gemini), LangChain Recently, I’ve been working on applied Generative AI integrations, including AI-powered resume analysis and intelligent automation, with a strong focus on reliability, fallback handling, latency, and measurable impact. I’m also the Founder & Developer of india-jobs.in, where I built a high-performance job aggregation platform with sub-second APIs, AI-driven resume insights, and scalable AWS infrastructure. What drives me: • Writing clean, maintainable code • Designing systems that scale under real load • Solving complex problems with simple, practical solutions • Continuous learning across system design, cloud, and AI 📌 Open to: Software Engineer / Full Stack Developer / Backend Developer / Frontend Developer 📌 Primary interests: Backend systems, scalable web applications, cloud architecture, applied Generative AI
