+bio: "I'm Maanvi, a CS student who builds things, breaks them, fixes them, and learns something every time. My interests currently revolve around backend development, TypeScript, Go, and cloud-native technologies, with open source being where I learn the most. I'm the kind of person who asks a lot of questions, enjoys understanding how things work, and believes every conversation is a chance to learn something new. Layer5 has shown me how much a welcoming community can accelerate growth, and I'm excited to give back by contributing code, sharing what I learn, asking thoughtful questions, and helping others wherever I can."
