Introduction

ExtBit LLC is a US-based software engineering studio specializing in low-level systems architecture, high-performance backend infrastructure, developer tooling, and Web3 cryptography protocols. Led by principal software architect Duzy Chan, ExtBit delivers production-grade solutions for enterprise B2B partners, technology startups, and open-source ecosystems that demand absolute precision, high throughput, and uncompromising data security.

Values

Our motto—"Extend the bit, protect your data"—defines our technical philosophy and operating principles:

• Technical Precision: We engineer software at the system level—from high-concurrency Go services and custom C++ build engines to kernel protocols—maximizing execution speed and architectural stability.
• Data Sovereignty & Security: We believe every user and organization has an inherent right to own, control, and protect their digital assets. We design privacy-first, zero-trust architectures that keep data secure against unauthorized access.
• Open-Source Integrity: We actively build, maintain, and contribute to open-source protocols, providing clean, auditable code, transparent legal practices, and long-term ecosystem reliability.

Tools & Developer Infrastructure

We engineer high-performance developer utilities, custom build engines, and decentralized data tools that give users complete sovereignty over their data and infrastructure:

• Modular Build Engines & Developer Tooling: Specialized CLI utilities and custom JIT compilation tools (like Smart) designed to streamline complex build pipelines and eliminate global namespace collisions.
• Zero-Trust & Cryptographic Access Control: End-to-end encrypted transport pipelines, time-bound signature authentication, and token-gated access control systems for private and enterprise applications.
• Decentralized Storage & Protocol Utilities: Native integrations for self-hosted nodes, P2P network connectors, and decentralized storage protocols (IPFS, Arweave, custom blockchain nodes).

Technical & Consulting Services

ExtBit LLC provides end-to-end engineering services, technical leadership, and protocol-level architecture for startups, enterprises, and Web3 teams:

• Systems Architecture & Low-Level Development: High-throughput Golang microservices, modern C++17/20 applications, embedded Linux drivers, and custom socket/network protocol optimizations.
• Web3 & Blockchain Protocol Engineering: Custom smart contract development, EVM/Solidity staking platforms, open-source node maintenance, and custom blockchain forks.
• Security Auditing & Code Refactoring: Profiling, memory optimization, legacy codebase migration (e.g., C++/Makefiles), and security-first architecture reviews.
• B2B Technical Consulting: Direct client engagements, milestone-driven contract execution, and full intellectual property transfer under standard US LLC agreements.
