Leonardo Theodoro

I’m an experienced software developer with 8 years in full-stack work, where I focus on building end-to-end products and leading technical decisions that translate directly into business impact. In my current role, I’ve been responsible for delivering solutions from problem discovery through production.

At Robin, I built a system that transformed the company into a job board by automating candidate recovery from rejected ATS applicants with Node.js, Express, TypeScript, Whatsapp API, and MongoDB—generating 1,000+ CVs in one month and achieving 50%+ conversion. I also refactored a legacy crawler and pipeline to solve stale candidate data, reducing update latency from 24 hours to ~10 minutes and enabling near real-time candidate availability.

I’ve consistently improved performance and reliability, including migrating to MongoDB 6.x to improve query performance by 30% and decrease database latency for high-traffic endpoints. I built operational tooling such as a Grafana dashboard to give product and engineering teams real-time visibility into pipeline stability and failure rates.

I care deeply about reducing manual work and accelerating engineering workflows—automating 5 ATS integrations for real-time candidate status updates, optimizing GCP CI/CD pipelines by automating App Engine version cleanup, and cutting pipeline execution time by 60%. I’ve also developed an AI ticket-triage assistant using Python, Django, and OpenAI (with RAG over past resolutions and documentation) to reduce non-bug tickets reaching engineering by ~70% while surfacing useful debugging hints and citations.
