Flowery Branch, United States - 12:29 pm local time
Principal/Staff Software Engineer with 12+ years of experience building scalable, AI-integrated, cloud-native platforms. I specialize in backend systems using Java, Spring Boot, and microservices architecture, as well as LLM/GenAI systems using Python, LangChain, and vector databases (FAISS, Pinecone).

I’ve successfully led distributed engineering teams to design and deliver real-time systems in fintech, healthcare, and supply chain environments. From designing secure REST APIs and CI/CD pipelines to deploying on AWS and GCP Kubernetes, I bring deep technical expertise and solution ownership to every project.

🔧 Core Skills:
• Java, Spring Boot, Python, REST APIs
• LangChain, OpenAI, HuggingFace, GenAI agents
• Kubernetes, Docker, PostgreSQL, GCP, AWS
• Event-driven systems, message queues, logging, observability
• DevOps & cloud infrastructure automation

📈 Why Clients Choose Me:
• Strong ability to take abstract business goals and turn them into production-ready systems
