Services

Focused help for Rust Ethereum infrastructure teams.

Engagements are scoped around concrete technical problems: implementation, architecture review, spec-to-production work, and reliability.

Fractional Senior Rust Ethereum Core / Infrastructure Engineer

For teams that need ongoing senior execution and architecture judgment without full-time hiring overhead.

  • Roadmap decomposition and technical sequencing
  • Rust implementation across protocol, execution, and node layers
  • Code and design review for high-risk infrastructure changes
  • Debugging execution, client, node, and reliability issues

Monthly retainer. Scoped after a technical call for ongoing senior Rust/Ethereum infrastructure needs.

Scope this engagement

Reth / REVM / EVM Client Engineering Sprint

For custom execution behavior, custom EVM logic, or execution/client complexity that needs focused implementation.

  • Reth and REVM architecture review
  • Execution-flow implementation
  • Correctness and reliability test harnesses
  • Handoff notes for maintainers

From EUR 12,000. Most implementation sprints are scoped in the EUR 12,000-40,000 range.

Scope this engagement

Ethereum Protocol / Node / P2P Infrastructure Review

For teams preparing a launch, migration, refactor, or major roadmap decision around node infrastructure.

  • Architecture review and risk assessment
  • Reliability and performance concerns
  • Implementation plan and sequencing
  • Prioritized recommendations

From EUR 7,500. Fixed-scope review after initial technical scoping.

Scope this engagement

Spec-to-Production Rust Protocol Sprint

For funded teams turning protocol or research specs into working Rust implementation.

  • Spec ambiguity review
  • Implementation plan
  • Prototype or production implementation
  • Tests, interoperability notes, and handoff docs

Scoped after a technical call. Best for teams with concrete protocol requirements.

Scope this engagement

Technical Domains

Narrow by design.

This is not a generic Web3 development offer. The work is centered on Rust infrastructure and execution-layer systems.

Good Fit

Strong-fit projects

  • Funded or revenue-generating team
  • Real Rust codebase with infrastructure complexity
  • Ethereum, EVM, L2, client, node, or protocol work
  • Urgent senior engineering bottleneck
  • Willingness to pay for high-leverage implementation help

Not A Fit

Work I do not take

  • Smart contract audits or Solidity security review
  • Tokenomics, legal, or compliance advice
  • Generic Web3 app development
  • NFT or meme-token projects
  • Token/equity-only compensation

Work / Proof

Engineering Track Record

I've spent the last six years working on Ethereum core infrastructure, L2 R&D, Rust clients, EVM execution, P2P networking, and production systems.

Ethereum Core & Client Work

Senior engineering experience across Ethereum infrastructure, client coordination, and production Rust systems.

EVM & Execution Engineering

Hands-on work with custom EVM behavior, REVM, Reth-derived clients, execution flows, receipts, simulation, and correctness.

P2P & Distributed Systems

Experience building networking components, peer-to-peer data transfer, client test infrastructure, and bandwidth-constrained systems.

Technical Leadership

Spec-to-implementation ownership, cross-team coordination, mentoring, architecture review, and delivery of complex infrastructure work.

Pricing Guidance

Scoped after technical context, not hourly.

Book a technical scoping call
  • Engagements usually start at EUR 7,500.
  • Focused reviews are commonly scoped from EUR 7,500.
  • Reth / REVM / EVM implementation sprints commonly start at EUR 12,000.
  • Most implementation sprints fall in the EUR 12,000-40,000 range depending on scope, urgency, and codebase complexity.
  • Fractional retainers are scoped after a technical call.

What affects scope

Codebase size and maturity, Review versus implementation, Reth, REVM, and client complexity, Test coverage and reproducibility, Launch urgency and handoff requirements.

Book a technical scoping call

For best-fit projects, the first call is technical: problem, codebase context, scope, urgency, and whether external help is the right move.
