I actively focus on infrastructure optimization, consistently saving clients 20–40% on cloud costs and handling advanced deployments like AWS Marketplace API integrations (Billing & Metering).

• AI & Advanced Integrations: Building production-ready AI features that drive real business value. I integrate modern LLMs (OpenAI, Claude, Google Generative AI), build AI agents, design automation workflows, and implement complex architectural solutions like AI agent cost optimization on AWS Bedrock.
