Full-Stack Web3 Developer Needed to Improve and Complete an Existing DeFi Trading Platform

Budget: 20000 USD Deadline: 10 days

Hello! I am ready to conduct an audit and refine your DeFi platform. I have significant experience in Web3 and DeFi (React, TypeScript, Python, Solana/EVM, integration of Web3 wallets, development of trading interfaces, and optimization of connections via WebSockets/API). I have already implemented complex trading systems with automatic risk assessment, transaction processing, and liquidity management. I will analyze the repository, fix dependency and build issues, close tasks related to trading, staking, and wallets, and prepare the project for production deployment. I am ready to evaluate the code immediately after access to GitHub is provided. Do you have an up-to-date list of already identified bugs/blockers, or should I start with a full technical audit?

Budget: 19000 USD Deadline: 45 days

Hello Oluwaseyi,
The first priority is to verify the actual state of the existing repository before changing isolated parts of the platform. I will begin by reviewing the frontend, backend, smart contracts, environment configuration, build process, target EVM networks, wallet connections, swap flow, staking logic, transaction handling, and current deployment setup.
Within the first 72 hours, I will provide a repository assessment, dependency and deployment map, list of blocking defects, contract and API risks, and a milestone plan based on the actual codebase.
After the assessment, I will stabilize the build, complete the unfinished frontend and backend flows, improve wallet connection and transaction error handling, verify swap and staking scenarios, fix agreed issues in the existing smart contracts, add tests for critical on chain and off chain operations, prepare Docker deployment, and update the setup and release documentation.
My practical background includes full stack integrations, Python and JavaScript automation, REST APIs, databases, external services, Telegram systems, and connecting accounting software with custom applications. I do not claim a large public DeFi portfolio or completed Web3 projects that I cannot prove. My proposal is based on a structured repository assessment, transparent milestones, and verification of every completed workflow.
The fixed price for the complete production readiness pass is 19,000 USD, with a term of 45 calendar days. This price covers the existing frontend, backend, deployment configuration, testing, documentation, and agreed corrections to the current smart contracts.
A separate independent smart contract security audit, third party service fees, creation of a completely new protocol, and a full redesign of the platform architecture are not included. Any requirement outside the current repository will be discussed and approved before implementation.

Budget: 19998 USD Deadline: 45 days

we already have a practically ready engineering approach for this kind of web3 trading platform, so we can adapt it quickly and move from repository review to production milestones ))

i can start with a technical assessment of the frontend, backend and smart contracts, then give you a clear milestone plan, timeline and cost estimate based on the actual code.

for a platform with wallet connection, swap, staking, transaction flows, api issues, security review and deployment preparation, i would estimate about 5 to 7 weeks for a proper production ready pass.
my preliminary budget is 19998 usd, but i would validate it after reviewing the repository.

key implementation direction
- stabilize build, dependencies, configuration and deployment pipeline
- audit wallet, trading, swap, staking and transaction flows end to end
- review smart contracts, permissions, edge cases and security risks
- improve api reliability, error handling, responsiveness and performance
- add practical testing for core on-chain and off-chain workflows
- update setup and deployment documentation so the platform is maintainable

relevant work examples
- https://business.ingello.com/vorfahr - ai and platform automation with complex product logic
- https://business.ingello.com/fractal - agent based automation and scalable system architecture
- https://systems-fl.ingello.com - our freelancehunt landing with company context

before the final estimate i would need 2 things
- repository access and current deployment or staging details
- target networks, contracts list and which trading or staking flows are already expected to work

i am available and can begin with the repository assessment inside the platform. Expand
