I spent 2 years as an AWS engineer inside AWS itself before going independent — now I build the AI and cloud systems startups and enterprises actually put into production. Over 9.5 years in IT (5+ focused on AI applications), I've shipped RAG pipelines, LLM-powered agents, and serverless AWS architectures that handle real production traffic — not demos. Recent work includes an AI system currently supporting 10,000+ daily users, a Neo4j knowledge-graph-backed retrieval system for intelligent document search, and serverless chatbots built on Amazon Bedrock and Pinecone for an enterprise gaming client. What I build: 🔹 RAG & AI Systems — Production RAG architectures, LangChain agent workflows, document Q&A and AI chatbots, vector search (Pinecone, ChromaDB, OpenSearch), Amazon Bedrock integrations, Neo4j knowledge graphs 🔹 AWS Serverless & Backend — Lambda, API Gateway, Step Functions, event-driven microservices, FastAPI/Flask REST APIs, Terraform/CloudFormation IaC, DynamoDB/RDS I care about cost-efficient architecture, security by default (IAM least-privilege, VPC design, and Secrets Manager), and systems that don't fall over at 2am. Clients keep working with me because I communicate proactively, ship clean and documented code, and stick around for the maintenance and iteration phase — not just the initial build. If you're trying to get an AI feature or RAG system from "cool prototype" to "reliable production system", that's exactly the gap I work in. Message me with what you're building — I'll tell you honestly whether it's a good fit before we start.
