Summary
👤
Senior🎓
Top SchoolAlex Sergeyev is a Technical Lead and startup CTO with over a decade of hands-on experience building cloud-native, IoT and data-intensive systems from Sweden’s Greater Stockholm area. He has led R&D and engineering teams through architectural rewrites, cost-optimizations and platform migrations—delivering a tenfold Azure cost reduction and cutting service latency from 800ms to 40ms, and designing an IoT pipeline capable of handling 1M measurements/s. Currently driving Cloud Foundation at PostNord while advising investors and founders through his firm Mooracle, he blends technical due diligence expertise with pragmatic execution. Comfortable across AWS, Kubernetes, Terraform, Ruby/Elixir and time-series architectures, Alex is equally fluent in high-level strategy and low-level protocol design (protobuf/Lua SDKs), a combination that consistently turns legacy systems into scalable, production-ready platforms.
