Solana no-loss lottery project developed by a team of three as part of Alyra Solana course completion. The concept was a pool-together clone on Solana. I wrote the programs (contracts) for: lottery creation, buying tickets, choosing winner, refund tickets / claim prize, staking contract (mockup) integration to simulate a lending protocol interaction. Developed and deployed on testnet two interconnected Solana programs: one for a no-loss lottery mechanism and one for staking. The staking program allows users to deposit funds that earn yield via integration with a yield protocol (a mockup for that project). The lottery program collects yield generated from all participants and periodically selects a winner using a verifiable randomness source (mockup for that project). I wrote unit and integration tests for both programs using the Anchor framework, simulated edge cases (e.g., no participants, early withdrawals), and deployed the programs on Solana devnet/testnet using Anchor CLI.

Designed a custom DeFi protocol architecture using Uniswap V3 oracles, chainlink and Compound-like lending. More than 7000 nSLOC, forked and customized compound v2, Implemented cross-chain bridging with LayerZero OFT, Wrote testing suite (foundry and hardhat), deployment scripts, made all the deployments on arbitrum and handled contract verification. More than 15 contracts deployed on mainnet. Audited by Sherlock security contest for 21 days Numa sherlock. Project TVL reached more than 1 million dollars.

Audited complex diamond-based NFT infrastructure (3 weeks audit). NiftyKit V3. Delivered report and fix suggestions.

Acted as a technical reference (tech lead) for the team, assisting with design choices and code reviews. Developed and maintained back-office financial applications in C++ and SQL. Wrote technical specifications and implemented core features. Handled production support, including diagnosing and delivering hotfixes for critical incidents.
