Are you looking to take your Generative AI concepts from a brittle prototype into a scalable, enterprise-ready production system? I am a Senior Software Architect with 13+ years of enterprise Java backend expertise, specialized over the last year in building production-grade Generative AI, Agentic AI architectures, and intelligent retrieval systems (RAG). The biggest challenge with Gen AI today isn't writing a prompt—it's orchestration, state management, latency minimization, and data security. My background in building high-throughput, fault-tolerant cloud architectures ensures your AI agents, custom LLM configurations, and vector workflows run seamlessly at scale. 🚀 WHAT I AM CURRENTLY BUILDING & INTEGRATING: • Agentic AI & Autonomous Workflows: Currently building "MagicTale," an advanced multi-agent story generation system that orchestrates collaborative LLM agents to dynamically structure, refine, and contextualize long-form narrative content. • Production RAG Pipelines: Architecting Retrieval-Augmented Generation using semantic search and vector data structures to ground LLMs in private business knowledge bases. • Spring AI & LangChain4j Integration: Connecting enterprise Spring Boot microservices natively to foundation models (OpenAI, Gemini, Claude, HuggingFace) with structured JSON outputs and function calling capabilities. 🛠️ MY CORE AI & ENTERPRISE TECH STACK: • AI & Gen AI: Generative AI Integration, Agentic AI Frameworks, RAG, Prompt Engineering, Spring AI, LangChain4j. • Backend Ecosystem: Java, Spring Boot, Spring Security, Hibernate, Maven, Gradle. • Streaming & Caching: Apache Kafka (for asynchronous AI event handling), Redis (for LLM session state caching). • Databases & Vectors: MySQL, PostgreSQL, MongoDB, Elasticsearch. • Cloud & Frontend: AWS (Lambda, ECS, EC2, S3), Docker, modern Angular, and NextJS. Whether you need to integrate an intelligent chatbot, orchestrate a network of autonomous AI agents to automate complex business workflows, or optimize a read-heavy system using advanced caching and vector indexing, I build it to enterprise standards. Let's schedule a brief discovery call to discuss your AI roadmap and design a robust, scalable architecture for your project!
