Participated in the design and development of multiple PoC AI applications that integrated knowledge graphs, vector databases, LLMs using the ChatDKG framework, delivering full-stack solutions in fast-paced, R&D-driven environments. Built and deployed a Telegram bot in Python leveraging ChatDKG to retrieve decentralized knowledge graph data, perform sentiment analysis, and provide interactive query capabilities via chat. Actively contributed to incident response and debugging efforts for high-priority node-side and client-side issues, helping identify root causes and implementing scalable, long-term fixes. Led the complete re-architecture of a decentralized data infrastructure to enable compatibility with Amazon Neptune as a triple store backend. Analyzed the existing architecture, which spanned multiple repositories, and designed a unified, more efficient structure for storing and querying graph data. Wrote detailed technical specifications and migration plans to support the transition to the new model. Coordinated the end-to-end data migration process, ensuring backward compatibility and maintaining functionality across all key features, including data creation, querying, and network interaction modules. Managed the redevelopment and testing of all system components to function seamlessly with the new centralized data structure.

Optimized form loading time in the desktop application by implementing a data retrieval filter during initialization. Also streamlined associated procedures for enhanced efficiency. As a result, the loading speed was 5x faster. Developed a desktop service interfacing with SEF’s API to manage invoice retrieval and resending for unsuccessful transmissions, ensuring seamless operation. Worked on migration process of a comprehensive desktop HR application to a web-based platform using .NET technologies, enhancing accessibility and scalability. The application enhances the client’s ability to effectively track and manage employee information, facilitating streamlined HR operations.
