Arandu
by Leonardo Cardoso
Arandu is knowledge, in Tupi-Guarani.
This is mine.
AI-powered incident analysis system that processes logs and alerts asynchronously to generate root cause summaries.
Webhook inspection tool — create unique endpoints, capture incoming requests, and inspect payloads in real time.
FastAPI service that classifies support tickets using LLMs, returning category, priority, sentiment, and suggested responses.
CLI tool that compares OpenAPI 3.0 specs and detects breaking changes across paths, parameters, schemas, and responses.
Financial transaction processor that applies deposits, withdrawals, disputes, and chargebacks to client accounts from CSV streams.
CLI tool for saving and executing named shell commands — bookmarks for complex workflows with runtime argument support.
I build backend systems and developer tools with a focus on reliability, clarity and real-world use cases. Currently focused on Python, AWS and distributed systems.
