PROFESSIONAL EXPERIENCE
Middle Full-Stack Developer | Confidential Client | Kyiv, Ukraine | June 2023 -
January 2026
Architected and developed a high-concurrency, horizontally-scalable real-time
streaming platform handling 100K+ concurrent users with sub-100ms latency using a
polyglot microservices architecture (.NET, Go, Node.js, Python)
Built WebRTC-based real-time communication infrastructure with custom codec
optimization (H.264, VP9, AV1) reducing bandwidth consumption by 45% while maintaining
1080p quality at 60 FPS
Designed and implemented 12+ Go microservices for high-throughput stream ingestion,
transcoding pipeline orchestration, and real-time analytics processing, achieving 50K+
requests/second per service
Engineered event-driven architecture using RabbitMQ message broker with Redis pub/sub
for real-time notifications, enabling sub-50ms message delivery across distributed services
Implemented hybrid database strategy using PostgreSQL (transactional data, user
management), MongoDB (session data, analytics events), and Redis (caching, presence
tracking), optimizing queries to serve 10M+ daily requests
Developed .NET Core backend services for user authentication, subscription management,
and payment processing, integrating with third-party APIs and ensuring PCI-DSS compliance
Built Python-based ML pipeline for content recommendation, stream quality adaptation,
and automated content moderation using computer vision models
Reduced infrastructure costs by 40% through intelligent auto-scaling with Kubernetes,
Redis caching strategies (95%+ hit rate), and database connection pooling
Established comprehensive monitoring and observability using Prometheus, Grafana, and ELK
stack, reducing mean time to resolution (MTTR) by 65%
Led technical architecture decisions, conducted code reviews across 4 programming
languages, and mentored 3 junior developers in microservices best practices

Key Technical Achievements:

Engineered custom WebRTC signaling server in Go handling 200K+ peer connections
simultaneously
