Summary
👤
Senior🎓
Top SchoolAécio Santos is a seasoned software engineer and postdoctoral researcher with 16 years of experience building research-driven systems at the intersection of machine learning, information retrieval, data management, and visualization. He has led and shipped production-grade open-source projects—most notably the ACHE focused web crawler used beyond its DARPA origins—and co-developed tools like Visus (interactive AutoML) and Auctus (dataset search) while at NYU. His work spans backend architecture, scalable data pipelines, and applied ML, with a track record of publishing in top-tier venues and mentoring graduate students. Now based at CWI in Amsterdam, he combines deep academic rigor (PhD NYU) with pragmatic engineering that turns research prototypes into operational software. An underappreciated strength is his knack for refactoring and optimizing legacy crawler and indexing systems into high-performance platforms that serve real-world users.
