About

Md. Shahla Zulkarnine profile

👋 Hey! I'm a full-stack engineer with 5+ years of experience building scalable, production-grade apps at Dabble Lab, where I worked across microservices, real-time systems, and AI-powered tools for global clients.

I specialize in TypeScript, Next.js, GraphQL, and Node.js, and I'm currently diving deeper into Go, Supabase, and LLM-based development with LangChain and OpenAI.

Outside of code? I enjoy jumping rope sessions, cooking, and exploring how tools shape workflows and creativity.
