I'm Anjan Kumar Paul, a DevOps Engineer based in Dhaka, Bangladesh, currently at Wall Street Docs, where I configure and maintain servers using Ansible, deploy Kubernetes applications with reusable Helm charts, and implement Keycloak-based authentication for enterprise clients.
With a B.Sc. in Computer Science & Engineering from United International University and 8+ years of progressive experience, I've built CI/CD pipelines, migrated monoliths to microservices at Sharetrip Limited, designed custom AWS architectures at Genese Solutions, and provisioned infrastructure with VMware ESXi at Essential Drugs Company.
I'm AWS Certified Solutions Architect (Associate) and passionate about infrastructure-as-code, container orchestration, and building observable, scalable systems. When I'm offline, you'll find me playing chess or table tennis.
Designing custom AWS cloud architectures for scalable, secure, and highly available infrastructure. Building reusable Terraform modules with Terragrunt to standardize provisioning.
Deploying and managing Kubernetes applications with reusable Helm charts using Go templating for multi-client deployments. Migrating monolithic architectures to microservices.
Designing fully automated CI/CD pipelines with GitHub Actions, ArgoCD, and Jenkins. Building HA self-hosted runner infrastructure and automating server configuration with Ansible.
Analyzing logs and metrics to troubleshoot application and infrastructure issues. Monitoring with Prometheus, Grafana, Loki Stack, Graylog, and Elasticsearch for full-stack visibility.
Implementing Keycloak-based authentication and HashiCorp Vault for secrets management. Working with event-driven architectures using Kafka, RabbitMQ, and MQTT Broker.
Managing databases including MongoDB, PostgreSQL, MySQL, Elasticsearch, and Redis. Scripting and automation with Bash, Python, and SQL for infrastructure tooling.
Configured and maintained servers using Ansible, creating reusable roles for databases (MongoDB, PostgreSQL, MySQL) and application deployments. Deployed and managed Kubernetes applications with reusable Helm charts using Go templating for multi-client deployments. Built a highly available GitHub Enterprise self-hosted runner infrastructure, automated with Ansible and monitored via Prometheus using custom Python metrics. Implemented Keycloak-based authentication and analyze logs and metrics to ensure system reliability.
Designed and maintained fully automated CI/CD pipelines using GitHub Actions and ArgoCD for reliable, repeatable deployments. Managed and optimized AWS cloud infrastructure (EC2, EKS, S3, RDS, ElastiCache) including monitoring, backups, and scaling. Containerized applications using Docker and supported migration from monolithic to microservices architecture. Built and documented reusable Terraform modules for AWS, standardizing infrastructure provisioning.
Designed and implemented custom AWS cloud architectures for scalable, secure, and highly available infrastructure. Built and automated CI/CD pipelines integrated with GitHub, Docker, Kubernetes, and Ansible — reducing deployment time and improving release reliability.
Worked on an in-house ERP software project, provisioning and managing application servers using VMware ESXi and designing stable, scalable infrastructure architectures. Built and automated CI/CD pipelines with GitHub Actions to deploy applications securely and reliably.
