Developed a test automation framework for electronic devices, enhancing back- and front-end applications. My efforts transformed an ineffective framework into a functional product, resulting in four successful client deliveries and establishing a CI/CD development environment. I migrated the back end to .NET Core and the front end to a React-based Electron app, significantly reducing memory leakage and stabilizing the system. I also introduced new terminology, simplified user experiences, and launched a zero-config app running concept.

My proposals led to the development of new modules like Stations and Data Analytics, and I set up an Azure pipeline for CI/CD processes. Additionally, I implemented a distribution and licensing mechanism for the Electron app, integrated with keygen.sh, and continuously optimized key performance metrics, reducing test times significantly. I played multiple roles in this high-load system, facing countless device and sensor requests. Among other things, I oversaw the team and worked on full-stack development and product architecture, demonstrating versatility and commitment in a startup environment.

SharePoint | Tengri BPM

https://www.tengribpm.kz/
Returned as a software architect to a company known for business process automation and transitioned traditional eDoc solutions into a low-/no-code business process management system. This was a shift from the company's original focus. Tasked with system design and team leadership, I introduced EventStorming to gather complex requirements efficiently and adopted DDD for its intricate domain.

Through iterative development, we achieved a smooth and predictable workflow. My role evolved to focus on upfront design, architectural oversight, and refining development processes with minimal coding involvement. I advocated for modern work methodologies, transitioning from Gitflow to trunk-based development to better suit our needs and streamline testing and release procedures. This strategic pivot significantly enhanced team agility and overall productivity.

Our team embarked on a critical project to revitalize our browser extension, ensuring its future viability and enhancing functionality. We initiated this journey by transitioning from the outdated MV2 framework to the more robust MV3 standard, shifting our codebase from JavaScript to TypeScript. This foundational upgrade paved the way for continuous improvements.

At the heart of our endeavor was a comprehensive redesign of the extension's architecture, transforming it into a configuration-driven system. This pivotal change minimized our dependency on web stores like Chrome Web Store, markedly improving user event conversions, system flexibility, observability, and reliability. This strategic overhaul allowed us to provide a vastly superior user experience independent of external platform constraints.

A key aspect of our project's success was the integration of rigorous unit and integration testing within our advanced CI/CD and DevOps practices. This quality assurance and deployment approach streamlined our release process, reducing bug occurrences and operational costs and demonstrating our team's dedication to excellence.
