I am Nrishinghananda Roy, a DevSecOps Engineer specializing in AWS, Terraform, and Kubernetes.
I architect secure cloud infrastructure using Infrastructure as Code (IaC), building environments that scale predictably under heavy load.
I take end-to-end ownership of reliability and security. Through zero-trust networks and resilient CI/CD pipelines, I empower engineering teams to ship rapidly and friction-free.
My work focuses on improving system performance, reducing operational overhead, and building reliable infrastructure that teams can depend on.
Provisioned and managed distributed infrastructure across more than 60 nodes using AWS and Terraform, introducing Infrastructure as Code, centralized monitoring with Prometheus and Loki, and automated deployments through GitHub Actions.
Architected and provisioned a fully automated Kubernetes homelab cluster driven entirely by GitOps principles via ArgoCD. Implemented advanced zero-trust networking using Cilium, integrated continuous vulnerability scanning with Trivy, and deployed a complete Prometheus & Grafana stack for deep cluster observability.
Architected and implemented a concurrent document generation microservice in Rust using the lopdf and docx-rs libraries. Replaced legacy Python scripts with a highly reliable service capable of filling templates, generating PDF and DOCX documents, and programmatically placing critical elements like signatures.
I approach infrastructure with a security-first, reliability-driven mindset. Managing cloud assets using AWS and Terraform, I incorporate strict access controls and robust CI/CD pipelines.
I architect performant backend services in Rust (Axum, Tokio). My focus is delivering software that handles concurrency safely, remains predictable under load, and scales efficiently.
I heavily utilize Python to build powerful internal toolings, high-performance web scrapers, and automated DevSecOps workflows, drastically reducing manual operational effort.
From capturing detailed application traces to monitoring cluster health, I implement centralized logging and metrics using Prometheus, Loki, and tracing frameworks to ensure complete system observability.
I understand the business context behind the systems I build. I take full ownership of features, making practical technical decisions that align with real product goals and fast-paced startup timelines.
I work comfortably with deep ownership and minimal supervision. Once the problem is clear, I plan the implementation, communicate progress, and deliver reliable solutions end-to-end.
