About Me

I'm Gauri Agrawal, a software developer with a strong background in full-stack development, backend engineering, and AI/ML. I specialize in building scalable, secure, and user-friendly applications — from real-time chat platforms to high-accuracy machine learning models. My approach blends clean code with thoughtful design, ensuring that every solution I deliver is both technically sound and impactful. Over the past few years, I've gained hands-on experience through internships at Flipkart and MythyaVerse. I consider myself a lifelong learner — constantly exploring new technologies, improving my problem-solving skills, and staying current with industry trends. My career goal is to lead innovative projects that merge cutting-edge tech with practical solutions, making a tangible difference in people's lives. Outside of work, I enjoy mentoring young developers, participating in hackathons, and exploring creative tech experiments. I believe in mindful innovation — building not just for performance, but also for people.
