Building Infrastructure That Scales,
Stays Secure & Ships Fast.
Senior Cloud & DevOps Engineer with 10+ years designing and operating production-grade infrastructure on AWS. I architect systems that reduce deployment time, cut cloud costs, and eliminate single points of failure — before they become incidents.
Professional Highlights
10+ years designing, building, and operating production-grade cloud infrastructure.
Infrastructure at Scale
Designed and operated AWS infrastructure serving production workloads across multi-AZ, multi-region environments. Delivered consistent 99.9%+ uptime with zero unplanned maintenance windows through proactive monitoring and automated self-healing systems.
Pipeline Engineering
Built enterprise-grade CI/CD pipelines achieving DORA Elite performer metrics. Reduced deployment lead time from days to under 1 hour, increased deployment frequency to 15x per week, and cut change failure rates from 23% to under 3% across multiple engineering teams.
Cloud Cost Optimization
Delivered sustained FinOps impact through right-sizing EC2 workloads, Reserved Instance planning, Spot Instance adoption for non-critical workloads, and eliminating unused resources via automated cleanup policies. Cost savings achieved without performance or reliability impact.
Security & Compliance
Embedded DevSecOps practices across delivery pipelines — automated SAST/DAST scanning, Trivy container vulnerability checks, HashiCorp Vault for secrets management, and IAM least-privilege enforcement. Security shifted left, not bolted on after deployment.
Mohammad Abdul Mannan Bhuiyan
Cloud & DevOps EngineerAbout
I'm a Cloud & DevOps Engineer with 10+ years building and operating production infrastructure on AWS. I bridge the gap between development and operations — designing systems that are resilient by default, automated wherever possible, and observable at every layer.
My technical philosophy is simple: infrastructure should be boring at 3am. That means SLO-driven reliability, everything in code, pipelines that catch problems before production does, and monitoring that pages on signal — not noise.
Right now I'm focused on Kubernetes platform engineering, FinOps at scale, and pushing teams toward DORA Elite performer metrics through CI/CD maturity.
How I work
Reliability First
SLOs over SLAs — design for failure before it finds you.
Automation > Manual
If it runs twice, it becomes a pipeline.
Observability
You can't fix what you can't see — instrument everything.
Shift Left
Security and quality baked in from commit zero.
Career
Experience
10+ years · USA · Japan · Bangladesh
Leading platform engineering and cloud infrastructure for a high-growth InsurTech SaaS product serving 50+ insurance carriers. Own the entire DevOps lifecycle — from IaC to production observability.
- Architected and own the multi-account AWS environment (prod, staging, dev, security) using Terraform modules and Landing Zone patterns
- Designed the GitOps CI/CD platform on GitHub Actions + ArgoCD — cutting deployment lead time from days to under 15 minutes
- Led Kubernetes platform migration (ECS → EKS), enabling self-service deployments for 8 engineering teams with zero-downtime rollouts
- Implemented DORA metrics tracking dashboard (Datadog) that drove the team to Elite performer tier within 6 months
- Drove 40% infrastructure cost reduction through Reserved Instance planning, right-sizing automation, and S3 lifecycle policies
