Daniil Khudenko
Council Member
Daniil Khudenko is a QA Manager and Lead QA Engineer with over 11 years of experience in software quality engineering, specializing in large-scale distributed systems, microservices architecture, and QA process transformation across fintech and enterprise environments.
Daniil Khudenko currently serves as Chief QA Expert at OTP Bank (Hungary Group), a role he has held since February 2026. In this position, he leads quality engineering across a high-load, distributed banking environment, building and scaling QA strategy across a microservices-based architecture while establishing quality governance standards aligned with strict banking and regulatory requirements. He implemented observability practices using ELK and OpenSearch, which accelerated incident analysis and resolution, and reduced critical incidents through proactive quality and testing strategies. He partners closely with development, product, and DevOps teams to improve release stability and mentors QA engineers to advance a quality-focused engineering culture.
Prior to his current role, Daniil Khudenko served as Lead QA Engineer at Gemini Soft LLC from January 2025 to February 2026. He built the company's QA department entirely from scratch, establishing both manual and automation testing functions, and developed the full suite of quality assurance standards, workflows, and supporting documentation. He introduced the ELK Stack for centralized log analysis, designed and delivered onboarding programs for QA specialists and technical hires across the organization, and contributed actively to improving processes in business analysis, development, and code delivery. His leadership drove the transformation of Gemini Soft's quality capabilities and fostered a culture of engineering rigor throughout the software development lifecycle.
From June 2023 to January 2025, he held the role of Lead QA Engineer at I-Teco (listed in his resume as H2Soft), where he again built a QA department from the ground up for an enterprise-level environment. He contributed over 4% of commits to a custom GitLab Community Edition branch, delivering modules for task management, wiki, service desk, and manual testing management. By automating critical QA processes using the Behave framework and integrating them into CI/CD pipelines, he achieved a 25% reduction in testing cycles and compressed time-to-market for new features from three months to two weeks. He also reduced critical incidents by a factor of four, achieving an average incident response time of two hours, and increased defect detection rates by 30% through close collaboration with product managers and developers.
Before that, Daniil Khudenko was a Quality Assurance Team Lead at Exon Group from January 2023 to July 2023, where he led the integration testing department for a large-scale construction-tech platform serving more than 42,000 users across 89 regions. The platform was integrated with government systems and required compliance with security and data protection standards across thousands of infrastructure projects. He implemented test automation, regression, and load testing frameworks, and established request tracing using ELK alongside optimized log management through Portainer to improve debugging and incident resolution. His regression testing and risk assessment protocols reduced post-release defects by 15%, and he mentored QA engineers through structured training programs.

Earlier in his career, Daniil Khudenko worked as a QA Engineer at a Software Product IT Company from August 2022 to January 2023, where he conducted comprehensive testing for a ticketing system serving the Moscow Metro and suburban transport network across web, iOS, and Android platforms. He tested PAX terminals for ticket validation, performed functional, regression, and integration testing, and increased API testing coverage by 20%, improving the system's reliability and scalability. He also worked with Postman and DBeaver to validate API and database interactions, contributed to the development of a client application and CRM system, and streamlined testing documentation standards that reduced onboarding time for new team members.
Daniil Khudenko has authored three peer-reviewed publications. His 2023 paper, "Methodologies for Accelerated Implementation of Quality Assurance (QA) Processes in Software Projects with Legacy Code and Missing Test Infrastructure," was published in the Universal Library of Engineering Technology. In 2024, he published "Modeling User Behavior with Markov Chains for Optimizing Regression Testing Paths in Multi-Module Software Products" in the same journal, applying mathematical modeling to improve regression testing efficiency in complex systems. His 2025 paper, "Application of End-to-End Testing Methods to Verify Compliance of BIM Models and As-Built Documentation in Digital Platforms," appeared in the World Journal of Advanced Research and Reviews.
His work has been covered by several prominent technology publications, including 3DNews, TAdviser.ru, and TechBullion, which have featured his contributions to quality assurance innovation and digital transformation in the banking sector.
