About
About MeI don't just keep systems running — I make sure they never go down in the first place.
When millions of banking transactions flow through systems every day, there's zero room for "it works on my machine." That's where I come in. As Senior Staff SRE at NatWest Group, I'm the person who ensures that mission-critical financial platforms don't just survive — they thrive under pressure.
Over 14+ years, I've gone from writing my first lines of code at IBM to architecting self-healing platforms that handle enterprise-scale workloads across regulated environments. The journey took me through MakeMyTrip's traffic surges, Myntra's peak sales, and Vertisystem's cloud transformations — each chapter sharpening a different edge of the blade.
I turn chaos into calm. Complex, distributed systems into predictable, autonomous platforms. My toolkit spans SRE, AIOps, FinOps, Kubernetes, and DevSecOps — but the real skill is knowing which lever to pull and when. I build SLO frameworks that make reliability measurable, observability pipelines that surface problems before users notice, and automation that fixes issues faster than humans can type.
Beyond the day job, I write about what I learn. Engineering Blueprints is my platform where I break down complex systems thinking into actionable guidance for engineers and architects who build at scale.
At NatWest, I'm scaling reliability as a product — partnering with engineering, security, and executive leadership to institutionalize SRE practices across the bank's digital platforms. Think SLOs, error budgets, incident governance, and cloud-native operating models — all in a heavily regulated environment where "move fast and break things" is not an option.
On the side, I'm deep into AIOps — exploring how LLMs and intelligent automation can reduce MTTR and make on-call less painful for engineering teams everywhere.

Summary
Gurpreet Singh
14+ years. IBM to NatWest. From writing code to ensuring millions of transactions never fail. I've built, broken, and rebuilt systems across startups, travel giants, and global banks — each time making them more resilient than before.
Today, I lead SRE & Cloud Engineering at one of the UK's largest banking groups, where reliability isn't a feature — it's the product. My work sits at the intersection of engineering, automation, and business impact: SLO frameworks, AIOps-driven remediation, FinOps optimization, and zero-downtime delivery pipelines across regulated cloud environments.
I don't just build platforms. I build the culture, practices, and engineering muscle that keep them standing at scale.
