Recommendations

Manager, Technical Support Engineering — Former Manager (Datadog)

“Krystian quickly masters complex systems and applies that knowledge in real customer scenarios… customers never feel left in the dark — he communicates next steps clearly and documents everything.”

Staff Azure Engineer — Former Manager (Datto)

“Thinks outside the box and solves complex challenges… creativity and determination consistently drive results.”

DevOps Engineer — Mentor

“Dedicated, disciplined and proactive — grasps concepts quickly, then applies them in practical real-world scenarios.”

Senior AppSec Cloud Support — Colleague

“Follows through to the root cause and prevents recurrence — mentors others and raises the team’s knowledge.”

Senior IT & Implementation Consultant — Mentor

“Working with Krystian has shown me what “world-class cloud talent” really looks like. At Amazon Web Services he was the networking‐infrastructure troubleshooter customers begged for when their entire VPC estate went sideways due to issues with AWS Firewall. I remember him tracing a cross-region connectivity meltdown where he parsed VPC Flow Logs, rebuilt route-tables, and tuned AWS Network Firewall rules—restoring traffic while explaining every step to a nervous C-suite in plain English. Incidents involving DDoS bursts, rogue DNS records, or balkanized security groups ended the same way: calm analysis, surgical fixes, and grateful customers. AWS recognized that consistency with multiple Resolves Hero and 5 Stars Hero awards, an Engineer of the Month plaque, and ultimately an AWS Rising Star honour. Krystian never stops at the quick win.”
