Projects & Case Studies

This Website: A modern, responsive personal portfolio built entirely on AWS serverless infrastructure.

• Infrastructure: Automated provisioning via Terraform (S3 & CloudFront) with custom modules.
• Secure Authentication: Eliminated long-lived Access Keys (AK/SK) by implementing GitHub OIDC to assume AWS roles with short-lived credentials for Terraform runs.

Private RAG Tool: A 100% offline tool that allows secure chat with sensitive PDF/Excel documents using local LLMs, ensuring zero data leakage to the cloud.

• Tech Stack: Built with Python, Streamlit, LangChain, and Ollama.
• Benchmarks: Tested against Llama 3 (8B) and Mistral-Nemo (12B). Mistral-Nemo proved more accurate in extracting entities from Spanish legal docs, did not test on gemma or pi3 due to the resource contraint on my personal laptop but these two should be more efficient compared to ollama or Mistral-Nemo
• Privacy: Uses ephemeral in-memory vector storage (ChromaDB) to ensure data is wiped instantly after analysis.

Roadmap: Enhancing the static portfolio with dynamic capabilities using a Serverless architecture.

• Implementing API Gateway as the REST entry point.
• Developing AWS Lambda functions (Python) to process contact forms and dynamic content.
• Integration with DynamoDB for data persistence.

Infrastructure as Code: Built a reusable Terraform module to automate the deployment of secure, high-performance static websites.

• Provisions ACM Certificates for SSL/TLS.
• Configures CloudFront Distribution with default cache behaviors and CloudFront Functions.
• Secures S3 Buckets with OAI/OAC policies.
