I will build cross chain and web3 integrations
Web3 Engineer focused on secure smart contracts and scalable dApps
I build secure and scalable dApps across DeFi, RWA, and governance. Not just tokens or standalone smart contracts, but production-ready systems designed for real use, long-term growth, and clean archi...
About this Gig
Cross chain and Web3 integrations are not just about connecting networks or APIs.
Most problems appear later: broken flows, unclear logic between systems, weak backend structure, or integrations that stop making sense as the product grows.
I help define and structure Web3 and cross chain integrations for real products, with focus on clear system logic, reliable integration flows, and solid technical direction from the start.
What you get:
- integration flow review and planning
- cross chain logic mapping
- API and backend integration outline
- wallet and smart contract interaction planning
- system structure for larger builds
- implementation direction for approved scopes
- development support where included in scope
Why work with me:
- production-ready approach, not just isolated technical fixes
- focus on real product logic, not random integrations
- experience with Web3 systems, wallet flows, smart contracts, and cross chain architecture
- clear communication and structured scope
If you're building a serious Web3 product and need integrations that make sense technically and operationally, send me a message and I'll help shape the right approach.

FAQ
Why should you choose me?
I focus on production-ready Web3 systems, not just isolated integrations. That means I think about flow logic, backend structure, wallet interactions, smart contracts, and scalability from the start.
What’s included?
Depending on the package and scope, this gig can include integration flow planning, cross chain logic mapping, API and backend outline, wallet or contract interaction planning, and implementation direction. Larger approved scopes can also move into development separately.
What’s not included?
Unless agreed in advance, packages do not automatically include full frontend implementation, full backend development, complete deployment setup, external audits, tokenomics consulting, legal or compliance work, or long-term maintenance.
Which chains or networks can you work with?
I mainly work with EVM-compatible ecosystems and broader Web3 systems involving multiple networks, wallet flows, and smart contract interactions.
Are these full implementation packages?
No. These packages are designed as structured starting scopes for integration work. Larger implementation phases can be quoted separately based on the approved scope.
Do you help with backend and API integration too?
Yes. I can help think through both the user-facing integration flow and the backend or API logic that supports it, depending on the agreed scope.
What do you need from me to get started?
The best starting point is any of these: a short product description, integration goal, flow notes, wireframes, existing codebase, smart contract details, or examples of similar products.
