Introduction

ExtBit LLC is a US-based software engineering firm specializing in zero-maintenance web architectures, high-performance developer tooling, and low-level systems infrastructure. Led by principal software architect Duzy Chan, ExtBit delivers production-grade products and enterprise B2B consulting for teams that demand absolute precision, architectural stability, and uncompromising data sovereignty.

Values & Engineering Ethos

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

  • Zero-Maintenance Architecture: We build systems that eliminate technical debt. From static edge deployments to decoupled content engines, we remove database vulnerabilities and server patching cycles.
  • Zero-Trust & Data Sovereignty: We engineer privacy-first networks. Our tools ensure you maintain 100% ownership and control over your digital assets without middleman telemetry or unauthorized data harvesting.
  • Systems-Level Precision: Whether writing high-concurrency Golang microservices or orchestrating complex C++ build graphs, we engineer strictly for maximum execution speed and reliability.

Products & Open-Source Tooling

We engineer high-performance software utilities and engines that give users complete control over their infrastructure:

  • ExtBit WebFact: Our flagship productized engine for ultra-fast, unhackable static edge sites. Manage content natively via Git/Markdown with zero database overhead.
  • Smart Build Engine: A high-performance CLI utility and JIT-compiled scripting language designed to orchestrate complex C++ and Golang compilation pipelines without namespace collisions.
  • Web3 & Decentralized Utilities: Native integrations for self-hosted EVM nodes, private P2P transport pipelines, and decentralized storage protocols (IPFS, Arweave).

Technical Services & Consulting

ExtBit partners with enterprise B2B clients, startups, and technical founders through flexible, milestone-driven engagements:

  • Architecture Reviews & Security Audits: Deep-dive codebase profiling, vulnerability patching, and smart contract verification, delivered as formal, publication-ready technical PDFs.
  • Custom Systems Engineering: Milestone-driven development for high-throughput backend services, legacy codebase migrations, and custom network protocol optimizations.
  • Enterprise B2B Advisory: Fractional technical leadership, continuous engineering retainers ($95/hr), and protocol-level strategy backed by standard US LLC contracts and 100% intellectual property transfer.

Impact on Data Control

We engineer software that enforces true data sovereignty. By embedding fine-grained permissioning and cryptographic verification directly into application architectures, our tools ensure your data remains strictly governed on your terms—eliminating unauthorized third-party access, tracking, and vendor lock-in.

Impact on Data Transmission

We build high-throughput, zero-trust transport pipelines that guarantee secure data exchange. Utilizing custom socket protocols, end-to-end encryption, and decentralized node topologies, we ensure sensitive payloads travel privately and efficiently—without exposing telemetry to middleboxes or unverified relays.
