Custom Engineering Scope & Engagement Models

← Back to Services

When off-the-shelf solutions and productized packages fall short of your exact infrastructure requirements, ExtBit LLC delivers custom, milestone-driven systems engineering and technical leadership.

Whether you need low-level network optimization, specialized Web3 protocol development, or custom static generator extensions, we partner directly with technical founders, CTOs, and enterprise teams to ship production-ready code.

1🛠️ Core Engineering Capabilities

We focus strictly on high-performance, high-reliability engineering across three primary domains:

  1. Low-Level Systems & Network Engineering: Modern C++ (C++17/20), Golang microservices, embedded Linux drivers, custom socket protocols, and memory profiling.
  2. Web3 & Blockchain Protocol Development: EVM smart contract architecture, custom protocol forks, staking engines, and automated security verification.
  3. Productized Web Engines & Pipelines: Custom WebFact generator development (index.js / Webpack loaders), automated CI/CD pipeline engineering, and cloud edge infrastructure (GCS / Cloudflare).

2🤝 Engagement Models

We offer three flexible contracting structures to align with your team's procurement processes and budget requirements:

2.11. Fixed-Price Milestone Contracts (Recommended for Defined Scopes)

  • Best for: Clear, well-defined specifications (e.g., protocol audits, codebase migrations, custom WebFact engine builds).
  • Structure: The project scope is broken down into verifiable, independent milestones. Payment is released only upon milestone acceptance and the passing of automated test suites.

2.22. On-Demand Engineering Retainers ($95 / Hour)

  • Best for: Ongoing maintenance, ad-hoc feature development, or continuous architectural advisory.
  • Structure: Billed weekly or monthly with zero long-term lock-in. Time is tracked strictly and transparently against completed engineering hours.
  • Book Hourly On-Demand Engineering Work

2.33. Contract Options: Direct US LLC or Upwork Escrow

  • Direct LLC Agreement: Standard US corporate contract with invoice billing (ACH, Wire, Credit Card via Stripe).
  • Upwork Enterprise / Escrow: For clients who require escrow protection or third-party platform billing, we support direct engagements via Upwork contracts.

3🛡️ Corporate Guarantees & Intellectual Property

Every custom contract executed by ExtBit LLC is backed by standard US enterprise protection terms:

  • 100% IP Assignment: All source code, documentation, and build assets are transferred entirely to your organization upon project completion (Work-for-Hire doctrine).
  • Mutual Non-Disclosure (NDA): We execute formal NDAs prior to reviewing proprietary codebases or sensitive trade secrets.
  • Publication-Grade Documentation: Complex architectural reviews and technical audits are delivered as formal, publication-ready PDFs (typeset in LaTeX).

4📋 The 4-Step Scoping Process

Getting a custom project started with ExtBit is straightforward and transparent:

  1. Initial Technical Inquiry: Send us your project summary, technical stack requirements, and target timeline via email or our contact portal.
  2. Architecture & Scope Call (30 Mins): We review your code repository or specification document under NDA to clarify technical boundaries and feasibility.
  3. Formal Scope & Milestone Proposal: We provide a detailed technical specification document outlining exact deliverables, milestone costs, and execution timelines.
  4. Kickoff & CI/CD Execution: Work begins immediately upon agreement. You receive direct access to development branches and automated build outputs throughout the execution phase.
