Staff Software Engineer
(2023/2024)
I was a Staff Software Engineer at Kaseya, primarily focused on
developing and improving our cloud-based backup and disaster
recovery solution.
In this role I Architected and developed microservices using Typescript, Node.js, and Docker to handle various components of the backup workflow, such as data ingestion, processing, and storage. After noticing a possible future issue connected to server utilization, I optimized and improved the performance of our backup processes by rebalancing the workloads between different storage servers based on resource utilization metrics.
Used technologies:
Node.JS, React.JS, ZFS, MySQL, AWS, Azure, Kaseya Cloud and more.

Product/Team Lead, Architect
(Dec 2019-2024)
Rescued a broken application from a previous contractor. Moved it from C# and Angular to Node.JS and React,
Re-engineered it from the ground-up with a multi-server architecture and horizontal scalability with Apache
Kafka in mind.
Took care of the entirety of client interaction and business requirements, translated those into milestones and tasks for execution. Later built up my team to a total of four people (including me) with two more planned.

Team Lead, Architect
(2017-2018)
In the architecture team, our task was to do pre-production on various projects, analyzing systems, setting up
frameworks, API systems, interactions, and coming up with solutions to problems.
A single person from my team would be assigned to a particular project where for the next 3-4 months we would make sure they're able to finish the project. We would perform training sessions (usually teach people with exclusively Java experience to become adept at writing frontend applications and integrate into the ecosystem as well as how to design backend properly).
Used technologies:
Node.JS, React.JS, Atlassian Jira, Atlassian BitBucket (GIT), Webpack, Jenkins and more.

STMIS Polska in Zakłady Azotowe w Tarnowie Mościcach is using our software in their day to day work, hosted on our servers on a xen cloud.
Provided and installed hardware in a hospital serverhouse.
