Rockstar🎓
Top SchoolAlexander Baygeldin is a backend engineer with 11 years of experience building scalable, production-ready platforms across media, healthcare, and infrastructure companies, currently based in Lisbon and working at Evil Martians. He has deep Ruby/Rails expertise—designing APIs for multi-client OTT platforms and rescuing high-stakes ad services—as well as experience across Postgres, Redis, Elasticsearch, Docker, and orchestration tools. Alexander also contributes to algorithmic open-source work: he implemented an optimal composition algorithm for Finite State Transducers in a .NET graph library, showing comfort with low-level data structures and correctness-focused testing. Comfortable spanning backend and occasional frontend work, he pairs pragmatic engineering with systems thinking to keep clients thin while retaining rich configurability.

Contributions summary:Alexander implemented an optimal composition algorithm for Finite State Transducers (FSTs) and integrated it into the existing FST framework. This involved modifications to the FST data structures and the introduction of new methods for composing FSTs. The user also added test cases to validate the correctness of the new composition algorithm. The work focuses on core algorithms and data structures related to FSTs within the .NET environment.
