ABOUT PRATIP D.
Senior Site Reliability Engineer with 14+ years in AWS, Kubernetes, Terraform, and platform engineering. Currently at Bondsmith, a UK fintech in cash savings and deposit management, where I own the full cloud platform - from EKS clusters and CloudFront distributions to Lambda tooling, RDS databases, and CI/CD pipelines.My core focus areas include infrastructure as code with Terraform across multi-environment workflows, Kubernetes orchestration and GitOps with ArgoCD on Docker-based containerised workloads, observability and monitoring using Elastic Cloud (SLOs, APM, anomaly detection), and security hardening including WAF policies, CSP enforcement, SAML/Cognito integration, and automation using Python and Bash across Linux environments.I manage partner-facing infrastructure supporting white-label integrations, lead incident management and cross-company coordination with detailed runbook and playbook documentation, and build custom monitoring and alerting tools - including an AI-powered environment intelligence system using Lambda, Claude API, and Slack. On the database side, I work on PostgreSQL/RDS reliability including connection pool analysis, long-running query alerting, and custom Lambda-based Slack notifications.My background spans fintech, banking, media, and secure environments, with hands-on experience across DevOps, cloud architecture, high availability systems, and regulatory compliance. I\'m driven by building infrastructure that is reliable, auditable, and easy for teams to operate on.
