Our Services

Artificial Intelligence

Production-ready systems with LLM orchestration, vector database integration, and RAG-based architectures. Focus on secure data pipeline security, low-latency inference, and high-volume performance optimization for enterprise automation.

Case Studies

01

Replycorp

Multi-layer social attribution protocol linking engagement signals to on-chain conversion events. Engineered for high-throughput tracking with gas-optimized contracts and Merkle-proofed security to automate commission routing across decentralized networks.

Replycorp
02

Filosign

Zero-trust digital signature protocol eliminating centralized platform risk through permanent mathematical proof. Engineered with post-quantum cryptography (Kyber-1024 and Dilithium) and client-side AES-256 encryption to anchor immutable, quantum-resistant agreements directly to the Filecoin Virtual Machine (FVM).

Filosign
03

Haithe

Decentralized AI orchestration platform and multi-tenant marketplace eliminating centralized data silos. Engineered with a high-concurrency Rust backend and Metis L2 smart contracts to securely route multi-provider LLM workflows while automating per-call USDT micro-settlements natively on-chain.

Why Us?

How we deliver better
work that lasts

Performance First

Low-latency engineering and high-throughput are prioritized across every system layer. Strategic resource utilization ensures core technology remains scalable and never bottlenecks growth.

Red sports car representing speed

High Availability

Commitment to 99.9% uptime for mission-critical infrastructure drives the architectural design. Systems are engineered for resilience, maintaining stability through extreme traffic spikes and protocol shifts.

Gradient peach

Technical Integrity

Maintainable, production-ready code is the baseline to eliminate technical debt from the outset. Longevity-focused engineering ensures technology provides momentum rather than architectural friction.
