Summary
👤
Senior🎓
Top SchoolTatiana Racheva is a seasoned software architect and engineering leader with nine years of focused experience building scalable storage, workload management, and platform systems across Microsoft and Facebook. She has led teams that solve hard backend problems—scheduling, throttling, and resource tracking for O365 services—and architected Linux support and cold storage prototypes for large-scale storage engines. Tatiana pairs hands-on low-level systems work (contributions to high-profile open-source projects like Facebook's Flow and HHVM touching procfs, disk utilities and thread-safe SQLite use) with principal-level leadership in Platform and Substrate teams. Now taking a break to explore curiosity-driven programming, she brings a rare combination of production-grade systems design, DevOps sensibility, and a background in computational linguistics and music theory that informs creative problem solving.
