💼 About Me

I'm a software engineer with 6+ years of experience working across product-based companies like Amazon, Salesforce and Airbnb. My core strengths lie in backend development, deployment of LLMs and building applications for search relevancy using Opensearch and RAG.

🔧 Currently, I’m focusing on building high-throughput infra systems, and learning how to design and train LLMs from scratch. I’m especially interested in AI agents, the Model Context Protocol (MCP), and how emerging LLM technologies can be used for real-world automation and productivity.

🛠️ Tech Stack & Skills

Languages: Java, Python, TypeScript, Node.js, React
Infra/Cloud: AWS, Kubernetes (EKS), Terraform, Helm
Databases: Elasticsearch, OpenSearch, NoSQL
DevOps: Git, Jenkins, CI/CD Pipelines
Core Skills: System Design, Infrastrucute as Code, Microservices

🌱 What I’m Learning Now

📘 Building LLMs from scratch (inspired by Sebastian Raschka's book)
🤖 Experimenting with AI Agents and MCP
🧠 Studying attention mechanisms, tokenization, and training dynamics of foundation models

🚧 Side Projects (Coming Soon)

❤️ I Love Building

Small, focused LLM tools that solve real-world problems
Systems that abstract complexity through clean interfaces
Anything that mixes backend architecture with AI capability

⚽ Personal Touch

I recharge by playing 🏏 cricket, ♟️ chess, and the occasional 🎮 CSGO.
A favorite quote that guides me:

"Stay curious, stay humble."

Thanks for stopping by! 😊
Feel free to reach out if you'd like to collaborate or chat about LLMs, infra, or anything in between.
