Pavel Nesterchuk — Senior Backend and Systems Engineer

I build backend systems where correctness, performance, and real-world constraints matter. My work spans production-minded .NET services, deterministic Rust engines, real-time protocols, and blockchain infrastructure.

I like explicit boundaries, observable behavior, and deployment paths that survive outside the demo.

Engineering focus

Backend architecture Systems engineering Blockchain & DeFi
Clean Architecture, CQRS, APIs, authentication, data and service boundaries Concurrency, real-time protocols, simulation engines, deterministic cores DEX integrations, SDKs, wallets, AMMs, and multi-chain infrastructure

Technology landscape

Layer Tools and domains
Backend C#, .NET 8, ASP.NET Core, REST APIs, WebSockets, background services, API gateways
Architecture Distributed systems, microservices, Clean Architecture, CQRS, domain modeling, real-time and event-driven flows
Systems Rust, async and concurrent systems, deterministic engines, simulation architecture, Bevy ECS
Data PostgreSQL, EF Core, schema design, migrations, persistence boundaries
Infrastructure Docker, Docker Compose, GitHub Actions, Linux, NixOS, reverse proxies
Blockchain & DeFi EVM, Solidity, AMMs, DEX integrations, wallets, Cosmos SDK, Solana, TON
Product frontend TypeScript, React, Zustand, Vite, PWA architecture
Quality Unit and integration testing, CI pipelines, observability-minded design

Correctness first. Complexity only when the system earns it.
