Summary

Rockstar🎓
Top SchoolAleksandr Kiselev is a pragmatic software engineer with over six years building high-load, fault-tolerant systems primarily in Python and increasingly in Rust, experienced across event-driven architectures, async services, and Kubernetes deployments. He has driven backend features and microservices in high-traffic products—from a bank-wide event-driven CRM to social video platforms—optimizing performance (e.g., 5x faster feed service) and maintaining >90% test coverage. A hands-on mentor and reviewer, he decomposes complex requirements into deliverable tasks and lifts junior engineers while owning production incident fixes and releases. Aleksandr also publishes personal tooling like PSQLPy and TaskIQ, signaling a continuous learning mindset and a taste for debugging the thorny "HTTP 500" problems he quips about on GitHub. Based in Belgrade, he blends strong collaboration skills with a focus on efficient workflows and measurable impact.
