Francisco Guimarães

I am a results-driven software engineer with strong experience building reliable backend services and cloud infrastructure for large-scale systems. At Amazon I owned global invoicing services processing millions of transactions daily, maintaining 99.99% uptime and enabling compliance for new international markets.

My background includes designing financial APIs in Java/Spring, optimizing SQL and Oracle procedures to reduce database load, and creating data pipelines and dashboards that informed product pivots and reduced churn. I have implemented automation using AWS CDK, CloudFormation, Docker, and CI/CD tooling to halve release times.

I integrate machine learning and NLP tools into products, deploying FastAPI and LangChain-based APIs and using libraries such as TensorFlow, PyTorch, Scikit-Learn, and XGBoost for data-driven features. I also researched blockchain identity for IoT, publishing work and deploying distributed Raspberry Pi nodes.

I mentor founders and lead programs, having coordinated a startup pre-acceleration initiative and supported early-stage entrepreneurs. I seek to apply my backend, cloud, and ML experience to impactful products that scale globally.
