Let’s talk
Available for remote workSecurity-firstUTxO-native engineering

Cardano smart contract engineering,from validator rules to transaction delivery.

I help teams reason about eUTxO architecture, implement Aiken and Plutus validators, construct off-chain transactions, and document the invariants that make contract behavior reviewable.

ABOUT

Technical, reliable, and security-driven.

I help teams ship Cardano smart contracts with strong correctness guarantees and clean system design.

Security-first

Invariants, threat modeling, and defensive design—built for audits and real-world edge cases.

Functional mindset

Clear types, pure logic, and predictable behavior for on-chain and off-chain components.

Remote-ready delivery

Async updates, incremental PRs, and documentation-first handoffs that keep teams moving.

PROJECTS

Work samples & proof of skill

Each project includes scope, architecture, and the stack—ideal for take-home style review.

Spending App

Educational eUTxO application

Educational project
PROBLEM

Make UTxO and extended UTxO concepts concrete through an application that connects contract rules to wallet interactions.

EVIDENCE

Scope and stack are documented in the downloadable CV. This site does not currently link an implementation repository.

ARCHITECTURE

Aiken validation logic with a TypeScript, MeshJS, React, and Next.js off-chain interface.

Educational resource
PROBLEM

Compare on-chain and off-chain approaches across the Cardano development ecosystem.

EVIDENCE

Scope and stack are documented in the downloadable CV. This site does not currently link an implementation repository.

ARCHITECTURE

Examples spanning Aiken, Haskell, MeshJS, Python, TypeScript, and command-line workflows.

BLOG

Technical library for production-minded engineers

Cardano engineering resources are the primary track. Production delivery notes cover the infrastructure needed to ship and operate technical products.

PROCESS

How I work with teams

Predictable delivery, low ambiguity, and strong documentation.

Specs → tests → implementation

Align on requirements, encode invariants, and prevent regressions with clear, testable behavior.

Incremental delivery

Small PRs, measurable checkpoints, and consistent progress that’s easy to review.

Remote discipline

Async updates, strong handoffs, and documentation that keeps work moving across time zones.

CONTACT
