Profile

Robert Nikolla. Full-stack engineer at XK Group since March 2023. I own production systems end to end: architecture, integrations, deployment and everything after launch.

My work centers on US telehealth and direct-to-consumer commerce: telehealth partner integrations, subscription billing, medication shipment pipelines, and the quiz funnels and checkouts that drive revenue. On two of those brands I'm the only engineer.

I use coding agents like Claude Code every day. The specs, architecture decisions and reviews stay with me. Turning non-technical stakeholders' requirements into clear specs is work I do by hand.

Let's build something meaningful.

I'm open to remote full-time roles and contract work with US and EU teams. I'm based in Kosovo (CET). If you need an engineer who can own a product end to end, let's talk.
