Lead Cloud Developer
Hi, I'm Md Zahirul Islam.
I automate and scale multi-account AWS platforms in high-availability, regulated environments — 8+ years running infrastructure on Terraform, GitLab CI/CD, and Ansible. On the side, I build indie mobile apps underrawbuild.de.

01About
I'm a Lead Cloud Developer with 8+ years automating and scaling multi-account AWS platforms in high-availability, regulated environments. I currently run a multi-tenant platform spanning 400+ customer systems across 4 AWS accounts and 4 regions, using Terraform, GitLab CI/CD, and Ansible — with a focus on observability, resilient backup/restore automation, and performance at scale.

AWS Backup & Restore Pipeline
- Problem:
- Manual, inconsistent backup/restore processes for RDS and FSx across a multi-account fleet.
- Approach:
- Built a GitLab CI pipeline driving Terraform to standardize backups and restores, with maintenance-window scheduling.
- Outcome:
- Repeatable, auditable backup/restore across 400+ customer systems.
EFS/FSx Performance Tuning
- Problem:
- Slow file transfer speeds impacting customer workloads.
- Approach:
- Diagnosed throughput bottlenecks and tuned EFS/FSx configuration; planned an FSx for Windows migration.
- Outcome:
- Measurable transfer-speed improvements and a clearer migration path.
AI-Powered Alert Intelligence Agent
- Problem:
- Alert triage across the platform was manual and slow to resolve.
- Approach:
- Prototyped an AI agent (IOA) backed by a Known Fix Library to suggest resolutions for incoming alerts.
- Outcome:
- Proof of concept for faster, more consistent incident response.
