Christos
Natsios.

Senior full-stack software engineer.

I build React and Node.js applications, from production workflows to customer-facing products.

Selected work

Professional software & client projects

Designed and built a refactor of the shipping manifests and labels for five operators: processing moved from the browser to the Node.js backend, service and database access unified, and each operator’s layout and accounting data separated. It halves response time in QA (~167 ms to ~80 ms).

  • Node.js
  • React

Things I’m
building.

UGV Nav

An autonomous ground robot: I’m building a Waveshare UGV01 rover around an NVIDIA Jetson Orin Nano and an Intel RealSense D435i to drive itself to a goal in a defined test area, with a classical obstacle-avoidance baseline first, then one ML contribution measured against it.

Project notes

A little background

Experience & approach

My work spans established production systems and independently delivered client applications.

At INTRALOT, I’m one of two full-stack engineers on the operator platform’s core applications, which serve 40+ jurisdictions across Europe, the Americas and Asia. I’ve delivered six operator go-lives end to end, maintain and extend seven markets, and own hotfixes from investigation to release.

I enjoy turning operational requirements into maintainable software, working across interfaces, APIs, data, testing, and release support.

Tools I work with

JavaScript · React · Redux · Node.js
SQL · PostgreSQL · MySQL · Jest

My skills page shows where and for how long I’ve used each technology.
