Rockstar🎓
Top SchoolMarko Jelača is a backend-focused software engineer with 9 years of experience building high-performance services using Node.js, Go, .NET and PostgreSQL from Novi Sad, Serbia. He has repeatedly delivered scalable APIs and data migrations—most notably cutting response times up to 10x by moving services from MongoDB to PostgreSQL and introducing Elasticsearch to speed filtering from 20s to 2s. Comfortable across microservices, Kafka, GraphQL and testing with Jest and fuzzing, he pairs hands-on coding with pragmatic DevOps and deployment experience. As a project lead he has run sprints, mentored junior engineers and worked directly with product teams and clients to shape requirements. Currently at Brighting, he focuses on NestJS APIs and query optimization, while previous roles include blockchain-focused Go development and AI/security data platform work. Colleagues will note his blend of performance-driven engineering and an eye for practical system improvements that yield measurable user-facing gains.
