Full Stack Senior Engineer / Sviatoslav

7+ years of experienceBangkok, Thailand

A senior full-stack engineer with 7+ years in Python, Rust, and blockchain. Deep, hands-on experience optimizing Solana's consensus layer and shipping production DeFi infrastructure (DEXs, bridges, multisig, HFT trading bots) on the network. Currently leading consensus architecture design for a Polkadot-based chain, bringing that same systems-level rigor in async Rust and low-latency networking to new problems. Track record: boosted Solana consensus throughput with an advanced VRF approach, designed novel consensus mechanisms, and shipped infrastructure from testnet to mainnet - all while pushing AI-augmented development practices into engineering workflows. Full-stack range from React/Next.js to Kubernetes-based DevOps, with the leadership chops to own technical direction.

Skills

  • Rust Systems Engineering: 5+ years building high-performance async applications with Tokio, Actix, hyper, and serde; embedded and no_std development for real-time systems.
  • Blockchain & Consensus Architecture: Designed and deployed a novel hybrid (SPIN) consensus mechanism for Polkadot-backed transaction finality while preserving 100ms block times; optimized Solana consensus throughput using VRF techniques.
  • Smart Contract & DeFi Development: 3+ years shipping DEXs, bridges, multisig wallets, and audited smart contracts across Solana (Anchor), Polkadot (PolkaVM/WASM), Solidity/EVM, and Cosmos SDK.
  • Applied Cryptography: Practical experience with zkVM, zkKYC, FHE, VRF, and ZK Merkle proof systems in production blockchain contexts.
  • Embedded & Real-Time Protocols: Built low-bandwidth VoIP/UDP communication systems with on-the-fly Codec2 encoding; expertise in ASN.1, Protobuf, and mission-critical embedded systems (including flying-vehicle software).
  • Full-Stack & DevOps: React/Next.js/TypeScript frontends, PostgreSQL/PostGIS/TimescaleDB backend design, and containerized deployment pipelines (Kubernetes, Docker, GitHub Actions, AWS/GCP).
  • AI-Augmented Engineering & Leadership: Drives adoption of AI-assisted development (Claude Code, agent orchestration, LLM context management) as a practice evangelist, while leading technical direction and mentoring project teams.
