Schedule Interview NowMy name is Vasyl R. and I have over 2 years of experience in the tech industry. I specialize in the following technologies: Solidity, Smart Contract, Ethereum, Solana, Rust, etc.. I hold a degree in Bachelor of Computer Science (BCompSc). Some of the notable projects I’ve worked on include: Raydium - Decentralized Exchange (DEX) on Solana, Optimism - Layer 2 Scaling Solution for Ethereum, Aurory - Blockchain Architecture for Web3 RPG Game. I am based in Zhovkva, Ukraine. I've successfully completed 3 projects while developing at Softaims.
I possess comprehensive technical expertise across the entire solution lifecycle, from user interfaces and information management to system architecture and deployment pipelines. This end-to-end perspective allows me to build solutions that are harmonious and efficient across all functional layers.
I excel at managing technical health and ensuring that every component of the system adheres to the highest standards of performance and security. Working at Softaims, I ensure that integration is seamless and the overall architecture is sound and well-defined.
My commitment is to taking full ownership of project delivery, moving quickly and decisively to resolve issues and deliver high-quality features that meet or exceed the client's commercial objectives.

As a blockchain developer on Raydium.io, I contributed to smart contract development, Solana blockchain integration, liquidity pool optimization, and security audits. I optimized smart contracts for secure transactions, developed protocols for enhanced Solana interaction, and improved liquidity pool performance with stability algorithms for market volatility. Additionally, I conducted security audits to fix vulnerabilities, ensuring the platform’s security. These efforts reduced latency, improved scalability, and enhanced the user experience.
Contributed to Optimism as a blockchain dev: wrote/audited Solidity contracts for L2 bridges, batching, and fraud proofs. Improved OP Stack (geth-based), built cross-chain messaging, and TypeScript tooling for deployment/tests. Upgraded sequencer and Bedrock migration. On frontend: built React UI, wallet connect, tx status, L1↔L2 logic, and governance flows. Solved calldata costs, upgradeability, chain switch bugs, and optimized dev/testing tools.
Developed and maintained Solana smart contracts for Aurory, including NFT minting, $AURY staking, and marketplace logic. Built secure on-chain systems for dynamic NFTs, item fusion, and token rewards using Rust and Anchor. Implemented SPL-based trading with full validation and PDA access control. Optimized compute usage and wrote test coverage to ensure performance and security across the game’s blockchain features.
