Freelance Blockchain Auditor & Developer

I'm a blockchain developer driven by passion for decentralisation, with a curiosity for applying the newest tech in this fast-changing field.

About Me

I am a freelance blockchain developer with a focus on Ethereum and EVM development. With over 20 years of experience as a full-stack developer, I have worked on a variety of projects ranging from small-scale custom smart contract development to large-scale decentralised applications. My expertise in Solidity and the Ethereum Virtual Machine (EVM) allows me to deliver high-quality code that is optimised, secure, and scalable.

Smart Contract Development

I provide custom smart contract development services tailored to your specific needs. Whether you need a small-scale smart contract or a large-scale decentralised application, I can help you build it.

Smart Contract Auditing

I offer smart contract auditing services to ensure the security and functionality of your smart contract code. With my expertise in security and ethical hacking, I can identify potential vulnerabilities and provide recommendations to mitigate them.

Consultation

I provide consultation services to help you understand the potential of blockchain technology and how it can be applied to your business. Whether you need advice on a specific project or want to explore the possibilities of blockchain, I can guide you through the process.

Recent Projects

Here are some examples of my recent work. Each project demonstrates my expertise in developing secure and efficient smart contracts.

NFT Game

I recently developed a fun and engaging NFT game that allows players to collect and trade unique digital assets. The game was built on the Ethereum blockchain and features custom smart contracts that ensure the authenticity and rarity of each NFT. Players can also earn rewards by participating in game events and competitions.

Decentralised Exchange

I developed a decentralised exchange (DEX) that allows users to trade a variety of ERC-20 tokens without the need for a centralised intermediary. The DEX features custom smart contracts that enable fast and secure trades, as well as advanced order types and trading tools. The exchange is currently undergoning rigorous testing to ensure its reliability and security.

Trading Bot

I developed a trading bot that leverages custom smart contracts to automate trading strategies on the Ethereum blockchain. The bot uses advanced algorithms to analyse market data and execute trades in real-time, allowing users to take advantage of market opportunities without the need for manual intervention. The bot is also highly customisable, allowing users to tailor their trading strategies to their specific needs and risk tolerance.

Development Process

My team and I follow a thorough development process to ensure that your project is completed on time and to your specifications.

Step 1: Discovery

We begin by thoroughly understanding your project and its requirements. We work closely with you to identify the scope of the project, the timeline, and any other important details.

Step 2: Planning

After the discovery phase, we create a detailed plan for the project. This includes a project timeline, milestones, and specific deliverables. We make sure that our plan aligns with your goals and expectations.

Step 3: Development

Once the plan is approved, we begin the development phase. We use the latest tools and technologies to develop smart contracts that are secure, efficient, and tailored to your specific needs.

Step 4: Testing

Before the final delivery of the project, we conduct rigorous testing to ensure that everything is working as intended. We check for vulnerabilities and perform load testing to make sure that the smart contracts can handle real-world usage.

Step 5: Delivery

Finally, we deliver the completed project to you. We work with you to make sure that everything is set up correctly and functioning as expected. We also provide ongoing support to ensure that your project continues to run smoothly.

Pricing

As a freelance blockchain developer, I understand that each project is unique and requires a personalised approach. I offer competitive pricing for all of my services and work with clients to develop a custom pricing plan that meets their specific needs and budget.
