AWS Cloud Engineer • Site Reliability Engineering

Building resilient cloud systems that stay calm in production.

I work on fintech infrastructure where uptime, change safety, and delivery speed matter most. My focus is operational clarity: automate the routine, instrument the unknowns, and keep teams confident.

01 // About

A Cloud Engineer focused on operability, not just infrastructure.

I work where delivery pipelines, production incidents, and infrastructure modernization meet. My role is to make systems easier to trust, easier to change, and easier to recover.

Automation

GitLab CI/CD, BuildKit, Terraform modules, repeatable workflows

Reliability

Incident response, runbooks, observability, production support

Cloud Systems

AWS networking, compute, Route 53, ECS, EMR, hybrid support

Platform Growth

Kubernetes and EKS exploration with operational discipline

02 // Experience

Production infrastructure work with real operational stakes.

Current work at Fiuu, September 2024 to present, centers on resilient systems, delivery velocity, and safe change management.

Cloud Reliability

Operate payment-critical AWS workloads across EC2, ECS, RDS, and EMR with alerting, runbooks, and incident response discipline.

CloudWatch New Relic SNS

Delivery Engineering

Design GitLab CI/CD flows with BuildKit, scalable runners, and Terraform-based release safety across multiple environments.

GitLab CI/CD BuildKit Terraform

Modernization

Led CentOS 7 to AlmaLinux 8 migrations and production cutovers with zero-downtime expectations and rollback planning.

Linux Runbooks SRE

03 // Case Studies

Infrastructure projects framed by product impact.

These are the kinds of problems I enjoy solving: operational drag, release friction, and risky migrations.

Pipeline Throughput Upgrade

Cloud Ops
Pipeline Throughput Upgrade

Refined build caching and runner orchestration so release pipelines stayed fast under higher team concurrency.

Outcome

Shorter feedback loops and fewer deployment bottlenecks.

Operational Reporting Automation

Cloud Ops
Operational Reporting Automation

Used serverless AWS primitives to automate recurring reports and low-value operational routines for internal teams.

Outcome

Less manual reporting and more repeatable cloud operations.

Lambda EventBridge Python

Zero-Downtime Linux Migration

Cloud Ops
Zero-Downtime Linux Migration

Moved production systems from CentOS to AlmaLinux with staged rollout control, service validation, and documentation.

Outcome

Modernized estate without disrupting payment-facing services.
