ORGANISATIONS
U.Stork Lab, Node JS Backend Developer 2023 – 2026
Regulatory Compliance & Inspection Management Platform Ukraine, Kyiv
Built a microservice-based inspection scheduling and violation tracking system used by regulatory
•

officers across 6 regional departments — reduced case resolution time by 45% through automated
routing and priority scoring.
Implemented WebSocket-driven real-time alert layer for field officers, cutting incident response lag
•

from 20+ minutes to under 90 seconds.
Developed compliance analytics dashboards exposing SLA adherence, violation trends, and officer
•

workload — adopted by department heads for weekly operational reviews.
Designed a document generation pipeline for automated act and protocol creation, eliminating 80% of
•

manual paperwork per inspection cycle.
National Procurement & Contract Lifecycle Platform
Architected an end-to-end contract lifecycle system handling tender creation, multi-stage vendor
•

approvals, and obligation tracking across 3 ministries — reduced average contract closure time from 18
days to 9.
Built an async event-driven integration layer (RabbitMQ) connecting procurement data to financial
•

reporting systems, ensuring real-time budget commitment tracking without blocking API response
times.
Delivered a high-throughput batch processing pipeline (BullMQ + PostgreSQL bulk ops) for quarterly
•

contract reconciliation — cut processing time by 55% compared to the previous manual workflow.
Implemented full audit trail per contract mutation with immutable event log — ensured compliance
•

with national procurement regulations and passed external audit with zero findings.
Asset Management Portal — Government Inventory & Write-Off System
Automated asset tracking, write-off wokflows, and approval chains — reduced manual data entry errors
•

by 70% through validation engines and business rule enforcement.
Delivered real-time inventory dashboards via WebSocket pushes to active sessions, ensuring all
•

operators see live asset state without polling.
Implemented async event-driven integration with accounting systems via RabbitMQ, ensuring reliable
•

data synchronization without blocking API response times.
Corporate Internal Portal — Internal Tools & Developer Platform
Decomposed monolithic internal tooling into modular microservices — improved system stability
•

during peak usage and enabled teams to deploy features independently.
Validated system capacity under traffic spikes using k6 load tests before major releases, preventing
•

incidents during peak operational periods.
Improved developer workflows by standardizing self-hosted API testing (Hoppscotch) and
•

documentation practices across 3 internal teams.

Deviars, Node JS Backend Developer 2022 – 2023
Built commercial backend systems focused on scalability, third-party integrations, and developer Kharkiv
experience.
Designed and implemented multi-step workflows and async processing (BullMQ, RabbitMQ), improving
•

process throughput by 40% under concurrent load.
Built resilient third-party integrations (payments, logistics, analytics) with async synchronization and
•

retry logic — reduced data inconsistencies by 60%.
Optimized database queries, caching (Redis), and API response structures — reduced endpoint
•

response times by 30–50% across key user-facing routes.
Developed configuration-driven business logic engines (pricing, reporting, calculations), enabling non-
•

technical users to adjust rules without code changes — reduced operational workload by 20%.
Implemented centralized error handling, input validation, and structured logging from the ground up
•

on new services, establishing reliability standards for the team.
