client-side rendering of large JSON datasets and media files.
• Built UI components for visualizing and managing complex field-mapping logic, including interfaces for
configuring XML-to-JSON data transformation.

highperformance backend (Fastify, Prisma).
• Participated in client task estimation, prepared technical proposals for the client side, and established a handoff
process for completed UI work.
• AI integration: designed and built the client-side SPA (React + TypeScript) for AI-driven products, including
MivozGPT. Implemented real-time streaming of LLM responses and built UI for prompt management and
conversation history.

degradation on timeouts) and fine-tuned the integration with the high-performance backend (Fastify, Prisma).
