Valentin D.

Hello,

I am a blockchain engineer, specializing in the design and implementation of robust smart contracts on Ethereum, Solana, and Starknet, with concrete expertise in DeFi (AMM, lending, etc.) and MEV.

Contact me to define together the best solution for your needs!

💻 Ethereum, Solidity

💻 Solana, Anchor

💻 Starknet, Cairo

💻 C++, Python, Lisp

✅Development of an automatic arbitrage system on DEX (production):

→ Off-chain algorithm for calculating arbitrage.

→ Use of Flash Loans.

→ Routing of "Just-in-Time" swaps, similar to DFlow (at execution, the router, for each A→B swap of an off-chain pre-calculated route, compared different A/B pools and chose the one that allowed obtaining the maximum B for the given amount A).

✅Development of an options Market Making system (production):

→ Development of a pricer based on the Black-Scholes model.

→ Prediction of future volatility with machine learning, backtesting against informed flow (in order to minimize the money lost to other actors who might take advantage of our mispriced quotes, rather than maximizing the money extracted from retail flow).

🚧On-chain Machine Learning (prototype):

→ Export of a TensorFlow model (float32 → fixed-point) to a Solidity implementation.

→ Writing of a Solidity library in fixed-point + tests demonstrating its correctness.

🚧Re-compilation at execution of Solidity code (prototype):

→ If a value in storage is very rarely updated, it can be relevant to redeploy the smart contract with this value as a constant each time it is modified, as reading will be less costly. This is ultimately quite close to compiling code at execution in Lisp.
