Production Rescue & Reliability
Root-cause analysis on live incidents and performance problems.
When something critical is slow, failing, or losing data, the job is to fix it without making it worse. I reproduce the problem, measure it, find the actual cause, and ship a fix with a way back if it's needed.
I have taken operations that ran for tens of seconds down to under two on live systems, checked against production data first.
More work
Fee-calculation performance on a high-volume public-sector platform
Fee calculation ran for tens of seconds on the heaviest records and blocked the UI. Measured 3.4x to 15.4x faster.
Migrating legacy systems into a platform that models the work differently
Close to two million records moved out of ten separate legacy systems, each from a different vendor with its own idea of what the data means. Getting the rows across is the easy part.
Business-intelligence dashboard for mid-market operations
A management dashboard that turns years of operational data into real-time financial-health, profitability and collections insight.
