SRE II @ Zeta | Kubernetes · Python · Payments Infrastructure | 250+ incidents, zero SLA breaches | Troubleshooting & Security

About

I automate the problems most SREs accept as permanent. Three years into running payment infrastructure at Zeta — 500+ microservices, 6 production zones, 42+ Kubernetes clusters per zone — I kept noticing the same thing: the toil everyone complained about was actually solvable. Nobody had just sat down and built the tool. So I built it. KRE (Kubernetes Resource Engine) now saves my team 15 person-days every sprint by doing what we used to do manually: pulling utilization from Prometheus, reading pod topology and JVM heap configs, and outputting right-sizing recommendations across 47+ namespaces. A companion node optimization script found $24,000 in annual cloud savings. A Vault automation platform cut secret search time by 97% — hours down to under 2 minutes. None of these were in my job description. I just saw the problem and fixed it. That instinct — see inefficiency, build the solution — is what I bring to every team I work with. At Zeta, I've handled 250+ production incidents on live UPI and credit card payment flows without a single SLA breach across 15+ months on-call. I've onboarded 5 production namespaces in a week, coordinated zero-data-loss database migrations, debugged Kafka DLQ failures end-to-end, and written the playbooks new SRE hires still use on day one. I care about three things: systems that don't break, automation that actually sticks, and teams that get sharper over time. Currently SRE II at Zeta. Open to Senior SRE and Platform Engineering roles where reliability engineering is treated as a first-class discipline — especially in fintech, platform, or cloud-native environments. → tusharthakur2007@gmail.com
