Top SchoolAntonio Velázquez is a software engineer with eight years of experience building developer-focused systems and machine learning tooling, currently based in Madrid. He has worked at Microsoft on both consumer-facing OneNote and on AI frameworks including ML.NET and internal PyTorch projects, contributing fixes and tests to notable open-source components such as ML.NET's TextFeaturizer and LightGBM integrations. Antonio blends applied ML and backend engineering—his early research implemented and visualized topic-mining pipelines (MinHashing, LDA) on large corpora—and he continues to improve robustness in production ML pipelines. Known for attention to edge cases and documentation, he now brings that practitioner’s rigor to developer experience work at Datadog.
