We are looking for a senior engineer.

Budget: 1150 EUR Deadline: 14 days

Good day, I have over 5 years of experience in development, often working with complex web platforms where security and scalability are important.

I developed my product Throngwatch myself from architecture to release: a SaaS with analytics, roles, subscriptions, and two languages, so I am familiar with the approach and organization of a complex platform.

I am aiming for the first working phase to be up to 2 weeks - I will provide details and an exact cost after discussing the requirements.

Is there any technical documentation or a schematic description of how you envision the logic of DEX and Tradingview at the start?

I look forward to your message in private!

Good day!

I have carefully reviewed the concept. This is not a separate smart contract, but a full-fledged Web3 product: DEX, AMM pools, liquidity, tokenomics, governance, analytics, TradingView interface, and further cross-chain interaction.

I am ready to take on the architecture and phased implementation of the project. I suggest not trying to cover all networks, bridges, and mechanics at once, but to first launch a secure MVP on one EVM network:

— connection of MetaMask, WalletConnect, and other wallets;
— non-custodial swaps;
— AMM pools and LP tokens;
— adding and withdrawing liquidity;
— control of slippage, deadline, and price impact;
— indexing of transactions and trading history;
— charts, prices, volumes, and liquidity;
— adaptive frontend;
— test and production deployment.

Technologies: Solidity, Foundry/Hardhat, OpenZeppelin, TypeScript, Next.js, wagmi/viem, PostgreSQL, indexer/Subgraph, and TradingView Lightweight Charts or licensed Charting Library.

I propose to divide the work into controlled phases:

1. Technical audit, architecture, threat model, and detailed specifications.
2. Smart contracts and automated tests.
3. Web3 interface and wallet connections.
4. Indexing, analytics, and charts.
5. Governance, staking/farming, and tokenomics.
6. Security, third-party audit, and launch.
7. Bridges and multi-chain — as a separate phase after stabilizing the main network.

Each phase will have a separate milestone, acceptance criteria, and handover of the source code. The third-party audit of smart contracts, infrastructure, liquidity, and legal verification of the operating model will be paid separately.

I can start with a paid architectural phase and, after reviewing the requirements, provide an exact budget and timeline for the implementation of the entire product. Expand
