• Deploy and manage scalable containerized applications on GCP, leveraging GCS buckets for structured and unstructured data storage across services.
• Built backend-centric Next.js services using SSR and API routes, integrating SQL and BigQuery to process large-scale datasets and improve API response latency by ~30%.
• Containerized applications with Docker, enabling consistent deployments and smoother release workflows across environments.

• Completed 8+ weeks of structured Core Java training, applying OOP, collections, and exception handling in 2+ mini-projects.
• Designed CI/CD pipelines using Git, Jenkins, and Docker, automating build and deployment for 3+ services and integrating Java, Python, and DevOps tools.

Python, PyTorch, LangChain, Hugging Face, FAISS, OpenAI API

• Built a Retrieval-Augmented Generation (RAG) chatbot ingesting 100+ documents, using sentence-transformer embeddings and FAISS vector search for sub-second semantic retrieval and citation-backed answers.
• Fine-tuned a Hugging Face transformer on domain QA pairs using PyTorch with LoRA adapters, reducing training memory footprint by ~60% on a single GPU.
• Orchestrated multi-step LLM workflows using LangChain agents and tool-calling, enabling structured query decomposition, function execution, and grounded responses via the OpenAI API.

AWS, Jenkins, Docker, Kubernetes, Terraform, Ansible

• Built an AWS-based CI/CD pipeline automating build, test, security scans, and Kubernetes deployments for containerized microservices.
• Configured a 10+ stage Jenkins pipeline integrating GitHub, Maven, SonarQube, Nexus, Docker, and Kubernetes; provisioned infrastructure with Terraform and Ansible, reducing setup time by ~80%.
• Implemented Trivy container security scanning and Prometheus-Grafana monitoring, achieving a 90% reduction in deployment effort.

Node.js, Express, MongoDB, JWT, Zod

• Built 10+ REST APIs for signup/signin and course CRUD with modular routing and Zod-based input validation, supporting Admin and User flows end-to-end.
• Implemented JWT authentication and bcrypt password hashing, securing user credentials and role-based access across all protected endpoints.

React, TypeScript, Node.js, Express, WebRTC, Socket.io

• Built a real-time video conferencing app with low-latency peer-to-peer audio/video streaming over WebRTC and a room-based architecture supporting multi-user meetings.
• Integrated real-time chat and join/leave notifications via Socket.io to improve meeting collaboration.
