### 3) WORK EXPERIENCE

Nov 2021 - Present 
**Senior Blockchain Developer | Rust | DevOps**
[Coinweb.io](https://coinweb.io/) --> web3 industry

- co-developed the Core for the Coinweb blockchain protocol (`90% of the code in Rust`)
- identified & handled multi-threading/concurrency issues
- performed various DevOps tasks & cost/performance optimizations
- developed and maintained CI/CD pipelines for automated testing and deployment
- designed analytics and notification policies (`OpenTelemetry, Prometheus, Jaeger, specialized dev bots`)
- integrated IPFS capabilities & separate L1s from the universe of PoW (`BTC, BCH, LTC`) and PoS (`ETH, BNB, Cosmos`) into the Core protocol
- developed smart contracts for the Coinweb protocol and Cosmos ecosystem
- actively participated in blockchain protocol dev discussions and code reviews, wrote design documentation, workflows & methodologies (`HackMD, markdown, PlantUML`), led & coordinated cross-functional teams

Results:
- Improved core protocol concurrency by implementing owner enforcement for background processes. 
- Integrated support for IPFS, Kujira, and Polygon into the core protocol, and adapted L2 Computer to handle relevant events. This also involved creating elements necessary for third-party infrastructure, such as developing a Coinweb-writer smart-contract template for Cosmos-like chains. 
- Developed a Rust-based agent with Slack integration to enhance monitoring of Core & L1 events and reporting of relevant issues. This agent also tracks custodial/broadcaster wallet balances and backend API functionality across different environments (development, production) while interacting with shards. 
- Managed and supported over 750+ Kubernetes pods and services for web3 infrastructure. Designed scripts and cronjobs for crucial backend data backup, including Staking and IPFS objects.

**Head | Machine Learning & MLOps**
[ND Group](http://www.nd-group.net/en/enter/) --> oil & gas automation industry

- MLOps development starting from systems design up to inclusion of data science & machine learning tools appropriate for a targeted environment
- optimized the code-base to work in constrained environments efficiently (`Raspberry PIs, self-service terminals, rewriting Python modules in Rust`)
- explored potential applications for machine learning to improve biz efficiency 

Oct 2007 – Present
**Research Fellow | AI & Political science**
V.M. Koretsky Institute of State and Law of the National Academy of Sciences of Ukraine
