Artem Samoliuk

Rust / Blockchain Engineer

Contributed to the core development and mainnet launch of a high-performance Layer-1 blockchain with fast block times and a custom Solidity-compatible smart contract execution environment. Designed and integrated new runtime modules and optimized network configuration through integration testing. Integrated and validated a Solidity contract execution environment and authored deployment guidance for external developers. Implemented an inbound cross-chain asset-transfer module and co-designed a secure bridge from the Ethereum ecosystem. Developed the bridge service and optimized Ethereum API query algorithms, reducing operational costs by 5x. Implemented precise transaction cost calculation and calibrated gas and weight fees for the network. Configured staking parameters and integrated the runtime module required for end-to-end staking functionality. Conducted an internal codebase audit and remediated three critical architectural vulnerabilities. Modernized the blockchain event indexer and completed a database migration with zero system downtime. Coordinated deployment, infrastructure testing, and release cycles for the successful mainnet launch. Authored technical documentation for secure token migration and supported complex production issues.

Blockchain / Rust Engineer

Built blockchain protocols, Rust backend systems, cross-chain infrastructure, and smart contracts across RWA tokenization, TON, Polkadot, EVM, analytics, and secure communications projects. Bidirectional TON-Polkadot Bridge (Jul 2025 - Nov 2025): Designed and implemented the architecture of a two-way bridge supporting native-token transfers between TON and a Polkadot parachain. Developed smart contracts for secure transfer of tokens with custom logic between independent ecosystems. Deployed the bridge contracts and validated the complete system through unit, message-flow, and end-to-end integration tests. TON Tokenized Gold and Jetton Smart Contracts (Apr 2025 - Jul 2025): Modified the standard TON Jetton contracts to add built-in transfer fees for a tokenized-gold product. Built unit-test coverage, calibrated gas consumption, and deployed the final contracts to mainnet. Created a token/USDT liquidity pool and performed end-to-end DEX market-operation testing. Blockchain Analytics Platform (Sep 2024 - Apr 2025): Designed an event-driven architecture spanning blockchain ingestion, Kafka, analytics services, Redis caching, gRPC, GraphQL, and PostgreSQL. Implemented an event indexer that processed blockchain data and persisted it to PostgreSQL or published it through Kafka. Developed analytics and aggregation services with Redis caching and a gRPC interface consumed by the API gateway. Defined Kafka message formats and retry policies, configured cache invalidation, and supported containerization and performance diagnostics. TON-Polkadot Blockchain and Pricing Oracle (Jul 2024 - Sep 2024): Developed runtime logic for issuing a native derivative asset priced from TON and DOT market data. Implemented an off-chain worker that aggregated TON and DOT prices from multiple external sources and supplied them to the runtime. Developed an on-chain oracle module for Jamton that consumed price data read from Chainlink price feed contracts on Ethereum by an off-chain component. Added unit and load tests, containerized network components, configured CI/CD, and deployed test and production networks. TON-Polkadot Account Abstraction R&D (Jun 2024 - Jul 2024): Built a proof of concept for cross-chain account abstraction that signed Polkadot transaction payloads using a TON wallet private key; evaluated reciprocal TON-Polkadot flows and identified wallet API limitations for arbitrary-message signing. TON DeFi Protocol Analysis and Adaptation (May 2024 - Jun 2024): Analyzed the STON.fi DEX smart contract architecture and forked and adapted the open-source contracts for company-specific requirements. Analyzed Hipo liquid-staking protocol logic and forked and configured its TON smart contracts for company-specific staking requirements. Curio Chain - RWA Layer-1 (Jul 2022 - May 2024): Designed and implemented blockchain runtime modules with unit and load-test coverage for an RWA tokenization network. Developed and integrated DeFi functionality for a DEX, including liquidity staking and reward distribution within the Curio parachain. Built a state-migration mechanism for moving the network from a standalone solochain to a relay-chain-validated parachain. Integrated EVM smart-contract support and contributed to XCM-based cross-chain functionality. Automated devnet, testnet, and mainnet build and deployment workflows, including node load balancing and environment configuration. Secure Messenger with Quantum Key Infrastructure (Nov 2021 - Jul 2022): Designed the MVP architecture and implemented a custom application-layer protocol over TCP with reliable delivery, sessions, and error recovery. Integrated quantum-generated keys for end-to-end message encryption and implemented lightweight key storage on a private blockchain. Built a minimal interface for conversations and connection status on the target portable device. Completed and tested the prototype and presented the solution at a specialized conference.
