Experience:
Java Developer / IncoreSoft FEB 2024 – PRESENT
Video Analytics System (face/LPR/object detection) · Video Management System (VMS, web UI) - on-premise deployments
• Built and maintained backend for real-time video analytics - pipeline processes up to 1,000 events/sec across 600
cameras
• Resolved an OutOfMemoryError during bulk import of 5 million face records into the face recognition database -
redesigned the import flow to use chunked streaming, eliminating heap exhaustion
• Designed and deployed a RAG-based internal support assistant over product documentation (using n8n, Qdrant and
OpenAI API) - reduced average ticket resolution time from 8 to 2 hours (4×)
• Optimized DB queries and REST API endpoints under production load, reducing response times on critical paths
• Investigated and fixed root causes of production incidents: broken pipelines, analytics errors, degraded response times
• Led on-premise deployments on client servers: environment setup, configuration, post-deployment validation
• Maintained CI/CD pipelines using GitLab CI + Docker + Playwright + TestNG
• Wrote technical documentation for system architecture and deployment procedures

Java Developer / TAXI 571 JAN 2023 – FEB 2024
Taxi mobile app backend · Inter-service order exchange system · Payment integrations
• Architected inter-service communication protocols and defined service boundaries, tech stack, and responsibility split
across services for a platform processing ~1,000 orders/day
• Transitioned backend for inter-service order exchange from monolith to microservices architecture, defining service
boundaries and implementing inter-service communication via REST/gRPC.
• Designed and implemented integrations with Fondy and WayForPay payment gateways from scratch — API auth,
webhook handling, error recovery
• Owned full SDLC on assigned features: requirements, design, implementation, testing, deployment
• Maintained production servers using Prometheus + Grafana + Uptime Kuma and responded to deployment issues

Java Test Automation Engineer / Solvd, Inc JULY 2022 – DEC 2022
