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.

  • 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.

Senior Back-end Developer and DBA

2013 - 2016
  • Led and guided the team to utilize PostgreSQL features, significantly boosting performance in a federal-scale eCommerce conversion back-end project by one of the country's top three telecommunication providers. Moved from Oracle to PostgreSQL.
  • Participated in an in-house startup boutique. Architected and co-architected dozens of startups in the early prototyping and business experiments phase.
  • Created a highly-security-agnostic cross-platform (Windows, Linux, macOS) messenger with encrypted local storage and Bitcoin cryptocurrency transfer using Java and JavaFX.

  • 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.

Back-end Developer

2008 - 2009
  • Implemented the signal-processing system for IoT traffic and smart houses for seniors and those with disabilities, with a complex, fully SQL-side-implemented rule-based engine for signal stream analysis.
  • Completed multiple Django-based projects that involved heavy PostgreSQL-specific features previously unsupported by the Django framework. Designed and published the methodology to combine them.
  • Received my feature patch, enabling the utilization of more complex features of RDBMS back ends, accepted in the mainstream Django codebase, and became officially listed in the Authors file of the Django framework.

Software Developer

2003 - 2009
Mera Networks / MFI Soft (now Orion Innovation)
  • Joined the multi-national telecommunications company Nortel Networks (led and mentored a 10+ member team) and developed the high availability (“5 nines”) telecommunication network back end through five, year-long software release cycles.
  • Analyzed the data from different decommissioned external databases for a major country-wide on-site project in India. Implemented the data conversion for live production data of 12+ million customers in 11 cities and ensured secure migration.
  • Analyzed external solutions for offsite projects and ensured safe conversions in six projects, four different decommissioned vendors, and five countries totaling about 10+ million affected customers.

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).
