Hi there 👋

I'm Taras. I build high-performance distributed systems for blockchain infrastructure.

I'm a protocol engineer with 9+ years building mission-critical distributed systems for electrical utilities (SCADA) and blockchain networks. Currently contributing to Bitcoin Lightning network with a focus on performance optimization and network infrastructure.

Recent Work

  • 🔧 Tackling bug fixes, gRPC performance and testing improvements in Lightning loop and taproot-assets repos
  • 🚀 Achieved 5.6x performance improvement in Hedera's protobuf serialization layer
  • 🏗️ Exploring high-throughput consensus mechanisms including Lightning watchtowers and Merkle Proofs

Current Focus

  • Protocol-level blockchain engineering (consensus, networking, performance optimization)
  • Fintech infrastructure and distributed systems at scale
  • High-performance systems in Go and Java

Background

  • 9+ years building high-availability distributed systems for electrical utilities (AspenTech/OSI)
  • Deep expertise with RedHat, database optimization, DevOps & test automation, and real-time data processing
  • Interdisciplinary degree in Mathematics, Computer Science and Finance/Economics

Tech Stack

  • Production: Go, Java
  • Infrastructure: AWS (Solutions Architect certified), Linux, Docker, PostgreSQL
  • Exploring: Rust, advanced consensus protocols, Kafka, and Redis

💼 Open to: Protocol engineering roles in blockchain infrastructure, fintech, and high-performance distributed systems

Selected Projects

  • taproot-assets PR #2070: Surface Custodian errors to gRPC/REST API layer - merged
  • Hiero HCS Replay: Go library for Hedera Consensus Service (HCS) timing replay. This helps users of the Go SDK with performance testing. Submitted to Hedera Apex Hackathon.
  • Dune Hedera Dashboard: Tracks Hedera Consensus Service message activity for developers evaluating HCS adoption. Employs a Python extract-transform-load (ETL) pipeline which automagically sends Hedera data to Dune Analytics via GitHub actions.
  • Hedera Network Monitor: Go-based infrastructure monitoring for Hedera network nodes
  • Token Vesting Contracts: Solidity smart contracts for token distribution mechanisms on ETH and Hedera
  • AWS Proof of Concepts: Proof of concept exercises for AWS architectures implemented with AWS CLI scripts and CloudFormation
