BENCH+ PROFILE

Daniil

Backend Engineer
Go distributed systems, blockchain infrastructure, and LLM-enabled backend platforms

Lead-level backend engineer with deep Go distributed-systems delivery, production blockchain infrastructure experience, and recent hands-on LLM platform integration work.

BEST-FIT USE CASE

Backend leadership or senior individual-contributor role building high-reliability Go services, consensus-critical infrastructure, cross-chain systems, or LLM-backed backend platforms with production release ownership.

Not the primary fit: Less aligned with roles focused primarily on frontend delivery, pure product management, manual QA, or infrastructure-only platform operations without backend ownership.

EVIDENCE HIGHLIGHTS

What supports the assessment

Led and implemented Go blockchain core work for two production networks, including node software, SDKs, explorer and wallet components, and cross-chain bridge functionality.

Implemented custom modules, bridge components, backend services, release pipelines, and coordinated live upgrades for an EVM-compatible payments chain taken from scaffold to mainnet.

Led chain-side engineering for a liquid-staking network, including custom modules, EVM precompiles, protocol migration, and mainnet upgrade authoring.

Designed and built consensus-level interoperability components, relayer functionality, EVM precompiles, and validator-signature verification for a layer-two interoperability system that passed external audit.

Stabilized a live production chain by addressing consensus non-determinism, chain-halting failures, replay of corrupted history, and state migration requirements.

Built confidential LLM inference backend components covering encrypted streaming, model routing, metering, SDK delivery, and scheduled agent runtime behavior.

Built autonomous agent and retrieval workflows using tool calling, JSON-schema outputs, PostgreSQL checkpointing, embeddings, vector search, and verification paths.

Delivered a real-time multiplayer backend using an authoritative server, Kubernetes-hosted ephemeral instances, messaging, gRPC, and shared Protobuf contracts.

WORKING STYLE

How they show up

Has worked directly with business owners on core backend and protocol delivery.
Has led core engineering while coordinating with teams responsible for surrounding services and applications.
For irreversible production releases, described coordination across engineering teams, node operators, and dependent projects.
Uses test-first and verification-oriented workflows when applying LLMs to coding tasks.
