Alex Murashkin is a founding engineer and backend specialist with 10 years of experience building high-performance, distributed systems and serverless architectures, currently based in Dubai. He combines deep AWS expertise (AWS Certified Developer) with strong JS (ES6) chops, extensive testing practice (Mocha/Sinon), and practical knowledge of databases and caching (Postgres, DynamoDB, Redis, S3, ElasticSearch). Alex has led remote teams and shipped decentralized security tooling and dApps, and has hands-on experience auditing Solidity smart contracts and integrating Web3.js. He is an active open-source contributor across systems and blockchain projects—improving psutil’s cross-platform sensors, optimizing Parity Bitcoin performance with Rayon, and hardening Tendermint client logic in Rust. Pragmatic and fast to adapt, he bridges research-grade systems work from his Waterloo background with product-focused delivery and CI/CD-driven infrastructure. A subtle strength is his low-level systems fluency (kernel/ARM work and OS monitoring), which informs more robust, observable cloud services.

giampaolo/psutil

Jun 2017 - Sep 2020

Cross-platform lib for process and system monitoring in Python

Role in this project:

Back-end Developer

Contributions:7 PRs, 75 comments, 1 issue in 3 years 4 months

Contributions summary:Alex primarily contributed to the `psutil` library, focusing on adding and improving OS-specific system monitoring functionalities. This included implementing temperature sensor readings for macOS, FreeBSD, and integrating CPU frequency information for FreeBSD. Furthermore, the user modified and expanded the Linux implementation of the `sensors_temperatures()` function, parsing data from various sources. These changes indicate an emphasis on expanding system monitoring capabilities across multiple operating systems.

The Parity Bitcoin client

Role in this project:

Back-end Developer

Contributions:9 commits, 2 PRs, 4 comments in 4 months

Contributions summary:Alex primarily focused on optimizing the performance of the Parity Bitcoin client. Their contributions include implementing parallel processing using Rayon for Merkle tree calculations, which significantly speeds up block processing. Furthermore, they improved the code by avoiding unnecessary data cloning. They also conditioned the use of Rayon based on the number of hashes involved.
