About

Code it. Ship it. Own it. 🚀 I'm a Fullstack Software Engineer with over 3 years of experience building modern, cloud-native applications using Golang, Node.js, React, and Python. I specialize in designing scalable APIs, distributed systems, and microservices architectures, with strong hands-on experience in containerization (Docker, Kubernetes), CI/CD automation, and AWS cloud infrastructure. 🌱 Recently, I’ve been diving deep into Generative AI integrations, working on real-time LLM-powered applications using LangChain, Pinecone, and OpenAI APIs. I enjoy building intelligent, high-performance solutions that blend backend systems with AI capabilities. 🛠️ Alongside my professional work, I'm an active open-source contributor, hackathon finalist, and run a developer YouTube channel with 1200+ subscribers, where I share insights on backend engineering, cloud tooling, and AI integrations. 📌 I’m currently exploring opportunities in Fullstack Software Engineering roles with exposure to DevOps, Cloud Infrastructure, and GenAI projects, preferably in remote or product-focused environments.
