Work Experience

Lead Architect

2022 - PRESENT
Fintech Company
  • Created a complete, independent cloud-based solution to optimize the parameters of customizable trading strategies through mass-backtesting at Amazon cloud workers.
  • Designed and implemented all system components singlehandedly, including cloud-based data storage, the refreshers of real-market trading data from the Binance API, back ends, DevOps procedures, internal APIs, and a user-friendly web front-end.
  • Implemented a highly scalable AWS-based parameter optimization engine, predicting costs and providing large savings using the Amazon Spot instances.
  • Discovered and implemented numerous workarounds to imitate various quirks and undocumented behaviors of the TradingView strategy execution engine, enabling the custom execution engine to stay in sync with the execution for thousands of trades.

Universa Blockchain
  • Integrated a whole new blockchain network with external blockchains (Bitcoin, Ethereum), implementing the cross-blockchain swap solutions, which have successfully converted thousands of transactions worth hundreds of thousands of dollars since then.
  • Designed and implemented UniCherryGarden, an open-source data-mining and data-cherry-picking solution for Ethereum to analyze the blockchain and represent its internal technical data (events, topics) in business-logic SQL view (transfers, balances).
  • Served in developer relations (DevRel) and evangelist roles. Set up and maintained a comprehensive knowledge base with all the technical resources and specifications.
  • Wrote dozens of original technical articles (English and Russian) and supported communities with thousands of members.
  • Guided teammates and was a go-to SME in the development team on multiple topics such as blockchains, Bitcoin, Ethereum, smart contracts, exchanges and trading, blockchain user expectations, and best practices.

  • Co-founded, designed, initially developed, and led the team to launch the distributed cross-platform (Linux, Windows, macOS) system for encrypted peer-to-peer data backup and storage (e.g., P2P Dropbox).
  • Won, as a CTO of the winning project, the cloud computing investment award by EMC² at the WebReady-2012 expo.
  • Involved in all aspects of early startup functioning, from technical design and architecture to business models, investment topics, and marketing materials.
  • Envisioned and implemented the flexible and adaptable system architecture that quickly pivoted the startup multiple times aftermarket needs, from secure P2P storage to centralized file cloud and software file storage API.

UniCherryGarden

https://github.com/UniversaBlockchain/UniCherryGarden
An open-source MIT-licensed high-concurrency Scala, Akka Cluster, and PostgreSQL-based data-mining server platform (and a set of client Java libraries and reference client software) to analyze the Ethereum blockchain-stored data and transactions. Re-indexed them in a ready-to-inject RDBMS-based efficiently stored form. This is essentially “a missing SQL index for Ethereum data.”

Fintech Company

An Amazon Cloud-based system to optimize the parameters for trading strategies through mass-backtesting at Amazon cloud workers. I was the sole architect and developer of all system components, from the highly-scalable and high-performance optimization engine and DevOps procedures to the user-friendly web UI. The architecture decisions involved extremely optimizing the user costs of launching the system in the cloud, reproducing the existing Pine script trading strategies and providing the means to optimize them; imitating and mimicking the undocumented quirks of the TradingView strategy backtesting engine, creating the future-proof architecture/APIs (and adapting to the new requirements).
