SERVICES
Zero-knowledge expertise for teams shipping real systems.
From an advisory audit of your proof-system choice to hands-on circuit development — practical ZK engineering for teams who need it done right, not just explained.

WAYS TO WORK TOGETHER
Advisory when you need a decision, hands-on when you need it built
◇
ADVISORY
Consultation
Get a second opinion before you commit — proof-system selection, architecture review, security read-throughs, or technical due diligence for an investment or partnership.
✓Proof-system & architecture review
✓Security-focused read-throughs
✓Technical due diligence
✓Fixed-scope, fast turnaround
✱
HANDS-ON
Technical Development
Bring me in to build — circuits, proving pipelines, verifier contracts, or a ZK feature for your product — delivered with tests and documentation.
✓Circuit design & implementation
✓Proving / verification pipelines
✓On-chain verifier integration
✓Code handoff with docs & tests
CORE CAPABILITIES
What I actually work on
Σ
Advisory
01
Proof System Selection
A clear-eyed comparison of Groth16, PLONK, STARKs, and Bulletproofs against your actual constraints — proof size, prover time, trust setup, and tooling maturity.
⬡
Hands-on
02
Circuit Engineering
Design, implementation, and optimization of production circuits in Circom, Noir, or Halo2 — with constraint counts and witness generation that hold up at scale.
◆
Advisory
03
Security Review
A focused read-through of your circuits and verifier logic for under-constrained signals, trusted-setup risks, and the failure modes generic audits miss.
▦
Hands-on
04
On-chain Integration
Verifier contract integration and the surrounding plumbing — proof generation pipelines, gas-conscious verification, and client-side proving where it's needed.
HOW IT WORKS
From scope call to handoff
1
Scope call
A short call to understand what you're building and what kind of help you need.
2
Proposal
A fixed-scope proposal with timeline and deliverables — no open-ended retainers by default.
3
Build or review
Hands-on development or a focused review, with regular check-ins along the way.
4
Handoff
Documentation, tests, and a walkthrough so your team fully owns the result.
ENGAGEMENT MODELS
Pick a shape, or we'll figure it out on the scope call
Fixed-Scope Review
1–2 weeks
A focused audit of one thing — a proof-system choice, a circuit, or an architecture decision — with a written report.
✓Written findings report
✓One round of follow-up Q&A
✓Good for a specific decision
MOST COMMON
Project Engagement
4–10 weeks
End-to-end delivery of a defined piece of work — a circuit, a proving pipeline, or a verifier integration — scoped up front.
✓Fixed scope & timeline
✓Weekly progress check-ins
✓Full handoff with docs & tests
Ongoing Retainer
Monthly
Continued access for teams shipping ZK features regularly — architecture input, circuit reviews, and hands-on help as it comes up.
✓Priority availability
✓Mix of advisory & hands-on work
✓Month-to-month, cancel anytime
FAQ
Before you reach out
Mostly proof-system selection, circuit development, and security-focused reviews for teams shipping ZK features — identity, privacy, scaling, or verifiable computation.
Both. Early-stage teams often start with a consultation to validate a direction before committing engineering time; established protocols more often bring in a project engagement or retainer.
Fixed-scope work is quoted after the scope call based on the deliverable; retainers are a flat monthly rate. You'll always have a number before anything starts.
Yes — most engagements involve working directly with your engineers, not handing off a black box at the end.
That's exactly what the scope call is for — tell me what you're building and I'll recommend a consultation or a project engagement based on where you actually are.
