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)
