Summary
🤩
RockstarAleksandr Lyapunov is a seasoned software developer based in Moscow with 12 years of experience building backend systems, currently contributing at Mail.Ru Group. He has a strong C++ background from his time at ABBYY and deepened his expertise in database internals through meaningful contributions to the high-profile Tarantool project, focusing on replication, tuple update logic, and test coverage. Aleksandr is pragmatic about code quality—removing dead code, enforcing style, and implementing tests—while tackling low-level functionality like set_lsn and update-delete operations. He combines production-grade engineering with a willingness to engage in core-system fixes rather than surface features, making him reliable for critical backend and data-layer work. An unsung strength is his blend of long-term product familiarity and hands-on bugfixing, which helps stabilize and evolve complex systems over years.
