As a subsidiary of a US company, Boltzmann Lab. We leverage deep technical expertise to deliver mission-critical solutions across several key domains.

Our core expertise includes:

High-Performance Financial Systems: We build complete, low-latency centralized order book trading systems from scratch.

Services range from low-level optimization of proprietary inference engines to application-level features like content summarization, automated customer support systems (integrating LLM APIs with knowledge bases), and multilingual AI applications. We offer full end-to-end AI development.

Modern Cross-Platform Development: We build high-performance, responsive applications using the latest technology. Our web stack utilizes React, Next.js, and TypeScript, focusing on speed, scalability, and optimal UI/UX. For mobile, we fully adopt Flutter to efficiently deliver cost-effective, optimal cross-platform solutions for both iOS and Android.
