Peru NCase studies & notes

I design cloud & AI systems built for security, clarity, and real-world use.

I design secure, scalable software systems and turn complex cloud or AI workflows into products that feel clear, usable, and trustworthy.

§ What I do

Three practices, one systems mindset

I work end-to-end — from target architecture to delivery to the threat model that keeps it standing.

01

Local-first AI

Product · AI
AI PDF Reader combines retrieval, local models, desktop packaging, and product UX.
02

Platform & reliability

Cloud
Kubernetes and IaC tooling — from infrastructure security review to incident-reliability intelligence.
03

Security design

Security
Threat models, trust boundaries, and secure delivery decisions are part of the project story.

GraphRAG Incident-Intelligence Copilot

Fused knowledge-graph structure with vector similarity so incident diagnosis is driven by evidence, not by a plausible-sounding guess.

Built an on-call copilot that fuses a service dependency graph with semantic search over past incidents, then has an LLM synthesize a grounded root-cause diagnosis and blast radius from ranked evidence.

AI SystemsPlatform EngineeringReliabilityKnowledge Graphs
  • Combined graph structure and historical precedent so root-cause candidates are both reachable and evidenced, not just semantically similar.
  • Reached a 1.0 hit-rate@3 and 0.944 MRR with hybrid retrieval versus 0.778 and 0.569 for graph-only in an ablation over chaos-injected incidents.
  • Turned incident labelling from an argument into a fact by generating ground truth through controlled fault injection.

Agentic Kubernetes IaC Security Reviewer

Combined deterministic security scanning with bounded agent remediation to make infrastructure findings easier to trust and act on.

Built an agent-assisted CLI that turns Kubernetes, Terraform, and Dockerfile scanner output into prioritized security reviews, control-backed explanations, and safely staged remediation artifacts.

Security EngineeringPlatform EngineeringDevSecOpsAI Products
  • Turned raw infrastructure scan output into a prioritized review workflow engineers can act on faster.
  • Added control-backed explanations that make findings easier to defend in platform and security discussions.
  • Reduced remediation risk by staging generated fixes outside the source tree with bounded retry logic.

AI PDF Reader

A private, local-first document AI product with grounded retrieval, desktop packaging, and strong UX.

Built a local-first AI PDF Reader that lets users upload documents, retrieve grounded answers, generate study guides, and run as both a web app and offline desktop experience.

AI EngineeringSoftware ArchitectureLocal-First AISecurity Engineering
  • Delivered a product that can run in browser mode or as a desktop app for Windows and macOS.
  • Combined PDF parsing, chunking, embeddings, retrieval, and local LLM answers into one polished workflow.
  • Improved privacy posture by supporting local GGUF models and offline packaging for sensitive document use cases.

Grounding Incident Diagnosis With a GraphRAG Copilot

This project pairs a service dependency graph with semantic search so an on-call copilot can name a likely root cause and its blast radius from evidence, not from a plausible-sounding guess.

What This Agentic IaC Security Reviewer Says About My Architecture Style

This project shows how I turn noisy infrastructure security findings into an explainable, remediation-focused workflow by combining proven scanners with bounded agent reasoning.

Building AI PDF Reader as a Real Product, Not Just an AI Demo

The difference between an AI demo and an AI product is everything around the model: UX, retrieval quality, runtime setup, packaging, trust, and documentation.

Threat Modeling a Local-First AI Desktop App

Local-first AI products feel safer by default, but they still need careful threat modeling around files, models, prompts, packaging, and desktop boundaries.
