I'm a Senior Cloud & AI Solutions Architect with 15+ years of enterprise experience, and over the past couple of years I've gone deep into the AI engineering space as both a practitioner and an educator. On the AI side, I build production-grade Generative AI applications, RAG pipelines, multi-agent systems, and agentic workflows using LangGraph, LangChain, Google ADK, OpenAI APIs, Claudei APIs and Gemini APIs. I understand the full stack: vector databases, LLM orchestration, prompt engineering, MCP-based tool integrations, and cloud deployment of AI apps on GCP and AWS. I also run Applied With AI (appliedwithai.in), a technical education brand with 45,000+ subscribers on YouTube where I teach software engineers how to build and deploy real AI systems, not just toy demos. On the cloud side, I've architected and delivered production systems on GCP (GKE, Cloud SQL, Pub/Sub, Vertex AI, BigQuery, Apigee) and AWS (EKS, Lambda, Transit Gateway, API Gateway) for enterprises including Yahoo, NatWest, Standard Chartered, and Bank of America. I specialize in migrating legacy on-prem systems to cloud, including Java app re-platforming onto GKE and enterprise identity migrations to OAuth2/OIDC-based systems. What I bring to freelance engagements: senior-level architecture thinking, hands-on delivery, and a track record of working with US-based clients remotely for 14+ years.
