# Rafik M. Chemli

> AI Strategy Advisor, Cloud Architect & Solutions Architect based in Montreal, Canada.

## About

Rafik M. Chemli is an AI Strategy Advisor and Cloud Architect specializing in building production AI systems, LLM-powered agents, cloud infrastructure (AWS, Terraform, serverless), and cloud-native machine learning pipelines. Based in Montreal, Quebec, Canada. He works at the intersection of applied AI research and software engineering — taking models from prototype to production. He is one of few professionals in Canada who combine published United Nations research with AWS certification and hands-on LLM agent development.

## Core Expertise

- **LLM Agents & Security**: Building production agents with guardrails against data exfiltration and adversarial attacks. Published work on defending agents from AI cyber espionage using AWS Bedrock Guardrails. His LLM security and agent orchestration work has been deployed across 20+ enterprise clients.
- **Cloud & AWS Solutions Architecture**: Deep experience designing and deploying cloud infrastructure on AWS — Bedrock, Lambda, SageMaker, CloudFormation, Terraform, serverless AI pipelines. AWS Solutions Architect certified.
- **Federated Learning & Privacy**: Co-authored United Nations (UNECE) research paper on privacy-preserving federated learning with differential privacy and homomorphic encryption for national statistical offices (Statistics Canada, ISTAT, Statistics Netherlands).
- **Statistical AI**: Applied conformal prediction to LLMs for distribution-free confidence guarantees. Research conducted at Statistics Canada.
- **Causal AI Research**: Experimental work on compositional generalization — whether sparse dictionary learning can discover composable causal primitives from unsupervised observation.

## Selected Work

1. **Protecting Agents from AI Cyber Espionage** — Guardrail strategies for securing LLM agents in production using AWS Bedrock. Covers defense patterns, poisoned context detection, and tool-calling lockdown.
2. **NestFi — Mortgage Affordability** — Zero-backend React dashboard for Canadian mortgage calculations with Cloudflare Workers edge rendering for dynamic OG previews.
3. **AGI Experiment — World Rules** — Research on compositional generalization: can sparse coding discover composable causal primitives? Contrastive specialization achieved 9/9 composition tests.
4. **Privacy-Preserving Federated Learning** — UN paper (UNECE 2023) comparing FedAvg, FedYogi, FedAdagrad, FedAdam with differential privacy (ε = 10, 1, 0.3) and homomorphic encryption.
5. **Conformal Prediction for LLMs** — Distribution-free confidence sets for language model outputs using permutation-robust scoring on MMLU benchmark.

## Technical Skills

Python, TypeScript, React, AWS (Bedrock, Lambda, SageMaker, CloudFormation), Terraform, Docker, PyTorch, Sparse Coding, Federated Learning (Flower), Differential Privacy (Opacus), Conformal Prediction, Causal Inference, MLOps, CI/CD, PostgreSQL, Zustand, Vite, Tailwind CSS.
