Avnish Ranjan

DevOps Engineer with 1+ year of experience building CI/CD pipelines, automating infrastructure, and supporting production observability for containerized applications. Hands-on with GitHub Actions, GitLab CI/CD, Docker, Kubernetes (Helm, Kind, Minikube), AWS EC2, and Ansible, with working exposure to Terraform.

Focused on DevSecOps and SRE practices: integrates SAST and container scanning (Trivy, Gitleaks), drives zero-downtime deployments, and builds cost optimization and observability workflows using Prometheus, Grafana, and AWS CloudWatch.

DevOps Engineer at HanuAI Pvt. Ltd. (2025-05 – Present)

Project: AI Bank App — github.com/AVNISHRANJAN/AI-BankApp-DevOps

• Built production CI/CD pipeline in GitHub Actions for an EC2-deployed app, integrating SAST and Trivy scanning to support zero-downtime deployments.
• Resolved recurring GitLab CI/CD failures across 2 production repos (env misconfig, deprecated DAST image, Docker caching, SSH key mismatches), cutting build-fix turnaround.
• Audited Helm charts for a Kubernetes/Django deployment, flagging plaintext secrets, PodDisruptionBudget conflicts, and manifest errors pre-rollout.
• Provisioned AWS EC2 infrastructure (IAM, security groups) with cost optimization focus; deployed GPU observability stack (DCGM, Prometheus, Grafana, CloudWatch) on an NVIDIA L40S instance.
• Used Ansible for configuration management across dev/prod hosts; maintain Docker Compose setups (multi-stage builds, Celery, health checks).

Software Engineer (Freelance / Contract) at Self-employed (2024-12 – 2025-04)

Project: Jarvis Arena —github.com/AVNISHRANJAN/jarvis-arena

• Containerized an AI-powered Spring Boot banking app with a local LLM assistant (Ollama + TinyLlama); built Docker/Docker Compose configs for app, MySQL, and AI server.
• Deployed on Kubernetes (Kind) via Helm — ConfigMaps, Secrets, PVCs, Horizontal Pod Autoscaler — for production-style, zero-downtime scaling.
• Set up GitHub Actions CI/CD, used Ansible for host config, and provisioned infra with Terraform; configured GitOps-based monitoring.
