About Me

I am Oleksandr Nashyvan. I build software: web and mobile applications, blockchain platforms, AI products. My first job was in 2008, and I have not stopped writing code since.

I run Moonion as CEO and CTO. I put the team together in 2011 and registered the company in the USA in 2021. We take small projects and large ones, low load and high load, from centralised and private systems to decentralised and open source, including the ones that need various services and hardware wired together. Our motto: "What we work on today, others will only think of tomorrow."

At 11X Ventures I am Co-Founder & Innovation Engineer: software architecture, emerging technologies, AI, scalable system design. That work turns bold technical visions into products people actually use. Bono is one of them, and this page is Bono.

At Waterfall I am Development Team Lead. Waterfall is a smart contract platform built on a Directed Acyclic Graph with a fast finality Proof of Stake consensus. I sit in the research team as well as the development one, so a fair number of the ideas in the protocol started as mine and I take them through to implementation. Since 2022 I have co-authored 22 published papers, 20 of them with a registered DOI, in venues including IET Blockchain, ACM DLT: R&P, Springer LNNS and IEEE.

Since November 2022 I lead the open source project of IEEE P3271.01, the IEEE draft standard for recurring transactions using distributed ledger technologies. It is the first structured non-custodial framework for automated recurring payments, in a space where trustless solutions did not exist. That work was recognised twice in 2025: the IEEE SA Emerging Technology Award from the IEEE Standards Association, and the IEEE Blockchain Technical Community Region 8 Technical Merits Award, presented at the University POLITEHNICA of Bucharest on 15 December 2025.

I am based in Prague, Czech Republic. I speak Ukrainian, English and Russian.

One of the critical components of our CI/CD strategy is the use of GitLab pipelines. By storing our code in GitLab, we enable a streamlined process for continuous testing and deployment. This setup allows us to update different environments—testing, staging, and production—effortlessly. Prior to deployment, our processes include comprehensive testing through our CI/CD pipelines, followed by seamless packaging into Docker containers. This method ensures uniformity across environments, minimizing the 'it works on my machine' syndrome.

A major challenge in CI/CD is balancing automated testing with manual oversight. Automation saves time and reduces human error, yet the importance of manual testing for UI cannot be overstated. Hence, my approach involves a hybrid model. Our test team actively uses artificial intelligence to generate and refine automated tests, covering a wide array of use cases, including negative scenarios often overlooked by developers. AI's role ensures broad test coverage, but crucially, manual testing validates our interface, addressing aesthetic and functional subtleties beyond AI's current capability.

The integration of AI in our testing pipeline has been nothing short of revolutionary, enhancing the efficiency and scope of automated tests. AI excels in crafting test cases that expand on basic scenarios, thus bolstering our code’s robustness. Nonetheless, the human element remains vital. Our testers are strategically positioned to design and execute manual checks, ensuring our projects not just meet, but exceed quality expectations. By aligning these methodologies, we maintain a productive synergy between machine efficiency and human insight.

In organizing our manual testing efforts, the testers rely on structured test cases and checklists to ensure thorough coverage. It’s a well-orchestrated dance between different skill sets, where testers’ understanding of tasks leads to creating precise test cases. Manual regression tests complement automated checks, bridging any gaps that automation might miss. This organized approach not only verifies functionality but fosters a shared awareness of project objectives among team members.

In conclusion, the deployment of CI/CD combined with AI in test automation has equipped us to tackle ever-evolving challenges in modern software development. It allows us to deliver reliable, high-quality software, keeping pace with industry demands. As developers and business owners explore the advantages of CI/CD and automation, the key lies in finding the right balance between automated processes and manual evaluation. I invite you to reach out for a deeper dive into these transformative strategies and see how they can elevate your own projects.
