CMTA
Open-source projects of the CMTAT ecosystem, developed as part of my work at Taurus SA for the Capital Markets and Technology Association (CMTA).
CMTAT [Taurus SA / CMTA / Solidity]
Security token framework to tokenize financial instruments on Ethereum and EVM compatible blockchain.
- Project: CMTAT [Solidity]
- Role: Smart Contract Developer
- Duration: 2022 — Present
- GitHub project
Skills: Solidity · EVM · Ethereum
CMTAT ACE [Taurus SA / CMTA / Solidity]
Integration of the CMTAT security token with Chainlink ACE (Automated Compliance Engine) for programmable, on-chain compliance through policy-driven controls.
- Role: Smart Contract Developer
- Duration: 12/2025 — 06/2026
- GitHub project
- Made in collaboration with Chainlink.
- Compliance rules are defined as on-chain policies and evaluated by the policy engine for each protected token operation.
- Issuers can configure transaction eligibility and conditions without redeploying the token or modifying its core business logic: KYC/allowlists, sanctions screening, transfer and volume limits, trading-hour restrictions, emergency pauses and reserve-backed minting.
Skills: Solidity · Chainlink ACE · Compliance · Security token · RWA
CMTAT FIX [Taurus SA / CMTA / Solidity]
On-chain representation of FIX (Financial Information eXchange) data for CMTAT, using deterministic encoding and a Merkle root commitment instead of storing raw messages.
- Role: Smart Contract Developer (integration and review)
- Duration: 12/2025 — 05/2026
- GitHub project
- The FIX encoding was implemented by Nethermind; it enables efficient verification of structured trade data without on-chain parsing.
- As part of my work at Taurus, I helped integrate the solution into CMTAT and provided feedback on the implementation.

Smart Wallet 7702 [Taurus SA / Solidity]
Smart wallet contract to which an EOA delegates its execution logic with EIP-7702.
- Role: Smart Contract Developer
- Duration: 01/2026 — 03/2026

address(this)) - Single-call execution (
execute) - Deterministic contract deployment via CREATE2 (
deployDeterministic) - ERC-1271 signature validation with ERC-7739 anti-replay protection

- Token issuers can apply compliance rules based on verified passport attributes while preserving user privacy through selective disclosure and zero-knowledge proofs.
- Potential use cases include restricting token ownership and transfers based on nationality, age, sanctions screening and verified identity.
- Designed to work with CMTAT and RuleEngine, so compliance checks apply directly to token transfers without exposing sensitive identity information on-chain.

HEIG-VD
Projects made during my studies at HEIG-VD.
Password manager [Rust]
A password manager to store password securely.
When a user creates an account on the application, an RSA key pair is generated.
- The private key is encrypted using a key derived from the user’s master password, and a hash of the master password is stored in
accounts.db. - Passwords added by the user are encrypted with their RSA public key and stored in
passwords.db. - To share a password with another user, the sender uses the recipient’s public key for encryption.
