I help teams turn AI ideas into production-ready systems: RAG applications, AI agents, LLM-powered workflows, enterprise knowledge assistants, and AWS-native GenAI platforms that connect to real data, APIs, security controls, and cloud infrastructure.
My advantage is the combination most AI projects need but many freelancers miss: enterprise application architecture plus modern Generative AI engineering. I can help you move from business problem to architecture, prototype, integrations, AWS deployment, observability, security, and cost control.
WHAT I CAN BUILD
- Enterprise RAG systems for company documents, policies, SOPs, technical content, and knowledge bases
- AI agents that use tools, call business APIs, follow rules, and return structured outputs
- AWS GenAI architectures using Amazon Bedrock, serverless services, APIs, storage, queues, containers, and monitoring
- LLM integrations with OpenAI, Anthropic Claude, Gemini, Amazon Bedrock, or similar providers
- AI automation workflows for operations, support, internal knowledge, document processing, and application modernization
- Architecture reviews for AI systems that are unreliable, expensive, hard to scale, or not ready for production
AI / GENAI FOCUS
RAG, advanced RAG patterns, embeddings, vector search, semantic search, reranking, knowledge graph + RAG design, AI agents, multi-step workflows, tool calling, structured outputs, prompt engineering, LLM evaluation, hallucination reduction, and production AI architecture.
ENTERPRISE / AWS BACKGROUND
My professional foundation is enterprise-scale application and cloud architecture: AWS, serverless architecture, microservices, Java, APIs, CI/CD, DevOps, infrastructure automation, observability, security, software supply chain, Nexus Repository, Sonar, Amazon ECR, SBOM, and production reliability.
That matters because real AI applications are not just prompts. They need data pipelines, authentication, authorization, API boundaries, monitoring, deployment strategy, cost controls, and maintainable architecture.
EXAMPLE PROBLEMS I CAN HELP SOLVE
- "We need a RAG assistant that answers from our documents with citations."
- "We have an AI prototype, but we need a production architecture our team can actually operate."
- "We need an agent that connects to our internal systems instead of just chatting."
- "Our chatbot gives confident wrong answers and we need retrieval/evaluation fixed."
- "We want to use Amazon Bedrock but need help designing the architecture and integration path."
- "Our LLM usage is becoming expensive and we need cost, latency, and reliability improvements."
TECH STACK
AI/LLM: Amazon Bedrock, OpenAI, Claude, Gemini, LangChain, LangGraph, LlamaIndex, RAG, embeddings, vector databases, structured outputs, tool calling, LLM evaluation
AWS/Backend: AWS Lambda, API Gateway, ECS/ECR, S3, IAM, CloudWatch, serverless architecture, microservices, REST APIs, Java, Python/FastAPI, CI/CD
Data/Search: PostgreSQL/pgvector, OpenSearch, Pinecone, Qdrant, semantic search, knowledge graphs, document ingestion, metadata filtering
HOW I WORK
1. Clarify the business workflow, users, data, and success criteria
2. Choose the right pattern: RAG, agent, workflow automation, search, or hybrid architecture
3. Build a focused prototype with measurable quality checks
4. Add security, deployment, observability, cost controls, and handoff documentation
5. Improve accuracy, latency, reliability, and maintainability before scaling
If you need someone who can think beyond a demo and design the AI system as part of a real production platform, I can help.
