Top SchoolRoman Melnyk is a Senior Software Engineer based in Valencia with 10 years of experience building backend-first, cloud-native systems across startups and engineering consultancies. He currently focuses on Golang and Kubernetes at CAST AI, combining observability tooling (Grafana, Prometheus, Mimir) with reliable data stores like PostgreSQL. Previously he led engineering at a gaming startup and delivered full-stack services using Python/Django, FastAPI, GraphQL and ElasticSearch, giving him strong end-to-end product instincts. Roman is comfortable moving between languages and stacks—Python, Go, JS—and designing scalable async architectures with Celery, RabbitMQ and Docker. His background in applied engineering (a Master’s in Mining and Mineral Engineering) and early QA roles give him a pragmatic, systems-oriented approach to reliability and performance. Colleagues describe him as a hands-on senior engineer who bridges deep technical execution with product-focused decision making.
