What I'm looking for

A senior full-stack or tech-lead role building TypeScript/React/Node platforms, remote from Serbia (employment or B2B) or Belgrade hybrid — ideally with an AI-native engineering culture. Available from 1 September 2026.

At Obsidian 22, I architected and delivered a UK commodity-trading platform from an empty repository to a live multi-tenant environment in four months: 13 NestJS/Fastify microservices across nine domain-driven bounded contexts. I owned the domain model, tenant security, Kubernetes GitOps delivery, observability, Terraform, and a 98-component React design system.

Across Levi9, Quantlabs, TNation, Comtrade, and Razor Communications, I've grown from front-end engineer to JavaScript Tech Lead, leading enterprise application and front-end architecture across e-commerce, payments, solar energy, fintech, and cloud-native products. I also govern AI-native delivery workflows and built a self-healing production agent using the Claude Agent SDK.
