## About

Senior Software Engineer \(promoted July 2026\) with 3\.5 years building the platform, identity and delivery software behind a bank's financial\-crime application and enterprise analytics clients\. What I build and run: \- Platform: a self\-service provisioning platform \(Python/FastAPI\) that deploys the full product into any Kubernetes cluster and cut installs from 5 days to 1\.5 hours, composed as a Helm umbrella chart of about 80 charts on AKS, plus 20\+ Terraform modules\. \- Identity: Aegis UAM, a Java/Spring Boot access\-control platform \(RBAC, separation of duties, maker\-checker\) with an OIDC backend\-for\-frontend and a Next\.js console, a shared auth library for Java, Python, Go and TypeScript, and a self\-hosted Keycloak platform\. \- Delivery: the company CI/CD hub \(reusable GitHub Actions used by 10\+ services\) with an org\-installable Claude Code plugin, a repo\-scaffolding tool, and the observability standard \(Prometheus, Grafana, Loki, OpenTelemetry\)\. Certified Google Cloud Professional Cloud Architect\. Based in Bengaluru and open to relocating to Europe \(Finland, Ireland, UK\) with visa support\. I also build open\-source Android tooling as a side project \(Linxr, github\.com/AI2TH\)\.
