Oleksiy Zinchenko Golang Developer
[відкрити контакти ](див. вище в блоці «контактна інформація») github.com/sryosz @srymad Odesa, Ukraine
Profile
Backend engineer with 3 years of production Go experience in distributed, high-load systems.
Built and maintained services handling up to 10k RPS, event pipelines processing 100k+
messages, and multi-chain Web3 infrastructure across Ethereum, Solana and Whitechain.
Comfortable owning a system end to end — from architecture and low-level performance work to
observability and delivery.

Professional Experience
DDTech 08/2023 – 04/2025
Golang Developer
Microservices platform; 30 services in total, 25 owned and maintained
by me.
Developed and supported HTTP/gRPC services across the platform,
•
from CRUD APIs to traffic-facing, high-load components.
Built the analytics/statistics pipeline on Kafka, ingesting bursts of up to
•
100k messages and aggregating data from multiple upstream services.
Ensured reliable inter-service messaging and consistent performance
•
under sustained heavy load.
Truggo Software 04/2025 – 06/2025
Middle Golang Developer
Government-backed insurance platform - a mission-critical system with
strict reliability and security requirements.
Joined as the first Go engineer and bootstrapped the project from zero:
•
repository structure, service architecture, technical standards and
development workflow.
Built core system components in native Go with a deliberately
•
minimal dependency footprint, to keep behaviour predictable and
auditable in a regulated environment.
Designed resilient service-to-service communication with secure
•
transport and fault-tolerant failure handling for a multi-layered
architecture.
Over 06/2025 – Present
Middle Golang Developer
Large-scale Web3 analytics and data platform operating under heavy
parallel load.
Designed and built the external platform API serving up to 10k RPS,
•
with WebSocket and gRPC streaming endpoints.
Integrated 3 blockchain networks (Ethereum, Solana, Whitechain) and
•
10+ third-party APIs into a unified data-aggregation layer with
continuous on-chain collection.
Reduced crypto transaction processing time from ~2 minutes to 10
•
seconds (12x) by redesigning the processing pipeline and replacing
sequential handling with a custom concurrent queue.
Implemented a custom queue system for high-throughput job
•
distribution, providing backpressure control and retry semantics under
load spikes.
