About this Gig
Secure, Production-Ready Web3 Development Smart Contracts, DeFi, and dApps
Are you looking for an experienced blockchain developer to build a secure,
scalable Web3 application? You're in the right place.
I specialize in:
Smart Contract Development (Solidity, Rust)
DeFi Platforms & Decentralized Exchanges (Uniswap-style DEX)
Solana Programs & SPL Tokens
EVM-Compatible dApps (Ethereum, Polygon, BSC)
ERC20 / BEP20 Token Development
NFT Smart Contracts & Marketplaces
Staking & Yield Platforms
Whether you're a startup launching your first token, an existing protocol
needing an upgrade, or a founder with an idea that needs to become a working
product I build with security and best practices at the core of every line
of code.
Why work with me:
- Audited coding patterns (OpenZeppelin standards, reentrancy protection, access control)
- Clear communication throughout the project
- Fully tested code before delivery
- Post-delivery support included
️ Please note: I do not handle private keys, wallet seed phrases, or custodial
funds. All development is code and deployment only your assets stay yours.
Keep your assets and information safe
Cryptocurrency services focus solely on developing and programming. Never share sensitive information or private keys with others.

FAQ
Do you work with both Solana and Ethereum/EVM chains?
Yes I develop on Solana (Rust/Anchor) as well as EVM-compatible chains like Ethereum, Polygon, and BSC (Solidity).
Will my smart contract be audited?
I build using industry-standard security patterns (OpenZeppelin, reentrancy guards, access control) and test thoroughly before delivery. For a formal third-party audit, I can recommend trusted auditing partners this is a separate service.
Can you deploy the contract for me?
Yes, testnet deployment is included in Standard and Premium packages. Mainnet deployment can be added depending on your gas budget and requirements.
Do I need to give you my wallet or private keys?
No I never require your private keys or seed phrases. All work is done via secure, standard development practices.
What if my project doesn't fit neatly into a package?
Message me with your requirements and I'll put together a custom offer.
