Achievements:

- Proven problem-solving skills related to production infrastructure, including Docker, orchestration systems like Mesos/Kubernetes, performance issues;
- Reduced time that is required for a preparing release from a man/day to man/hour by automating the building process;
- Average time of one-shot containers was reduced from the 30s to 10s by fixing issues with signals passing from orchestrator to a process;
- Made a more flexible/granular authorization model by migration from classic RBAC to Ubi-RBAC that allows giving more granular permission in the multi-tenant system;

Achievements:

- Built an npm library, that simplified communication with hardware devices (payment terminals, thermal/impact printers, etc) for its consumers, reducing their headache about binary structures and improving the overall performance of the team;
- Implemented a broader set of transports the library can use to send those binary structures to a device, by implementing adapters over popular Node.js native add-ons. These including Ethernet (TCP/IP), USB, RS-232, Bluetooth;
- The resulted library was used to implement a Point of Sale system and hide the complexity of hardware communication from PoS team;
