NX1

NetrixOne is a group of independent IT professionals spanning multiple areas of expertise

We focus on software development that is tailored to fit even the most complex and sometimes very niche demands of our customers (like network flow analysis or mounting a spectral camera to a drone 🚁😎👌). We have years of experience with big data analysis and interactive data visualization. For our clients we also offer developer-oriented consulting and training sessions.

Here's what we do

Consulting

developer-focused, solve real-world, everyday problems
introduce and review latest technologies and trends (Kong, Zeit, CloudFlare, PDF-Chromium, NWJS/Electron, Anychart, Geolocation, 2D DB index, …)
help configure proper CI (custom Gitlab runners, docker-compose, docker performance and security tips, …)
code review (focus on code quality and security)
help establish code review company culture (why, how to write reviews, what to look for, …)
server and application monitoring (Zabbix, VMWare)
server and network consulting (backups, bottlenecks, hardware, virtualisation, licensing, …)
system architecture design (API design, monolith breakdown)

Development

complex data processing (like maintaining a huge GeoIP database with historical data and blazing🔥 fast lookups)
data visualization (that is actually comprehensible to the user)
web/desktop app development (we enjoy building beautiful desktop apps in TypeScript/Node.js/Vue.js - that's not your grandma's UI)
cloud service integration (deploy your apps easily to AWS S3, integrate your business with SAP or connect with a payment gateway)

Testing

performance testing (on-demand tests are great, but we recommend regular checks with performance assertions)
security audits (let’s hit that new website, analyze your code, sift through the transitive dependencies and check for security issues in your business workflow)

Training

[Programming] PHP: how to design complex application
[Programming] Nette: how to create first-class applications
[Programming] JavaSript: prototype with Vue.js + Vuex + TypeScript
[Programming] Java: Spring Integration deep dive (logging, websockets, stateless retry, performance)
[Programming] testing (web) applications effectively: unit/integration/smoke tests
[Programming] writing secure code
[Tooling] RabbitMQ: performance HiPE (RabbitMQ best practice, performance tips, deploying RabbitMQ with HiPE)
[Tooling] Wireshark: tips&tricks for productivity (advanced filters, custom columns, payload carving, working with console)
