How I Work
I work iteratively, focusing on the areas with the most impact first. Rather than trying to fix everything at once, I identify and prioritize the bottlenecks that will give the biggest performance gains.
We can typically make huge improvements within the first month by targeting the right areas.
CPU utilization, memory usage, and response time drops of over 80% are not uncommon.
I usually sit in your team Slack/ team chat, and am available to answer questions and help with any issues that come up.
