Abdulah Amer — Site Reliability Engineer

About

Site Reliability Engineer in my career. Physicist at heart.

My work is all about solving large problems and improving every bit of code, process, and documentation I touch. I fail fast and often — my iterative process of solving problems is no different from debugging. I hit walls all the time, and this has led me to overcome challenges time and time again. I listen closely, ask many questions, and thrive in collaborative, intelligent, and kind teams.

I have built production-ready infrastructure across AWS, Azure, on-premises datacenters, and even small office servers. I have managed observability using Terraform and helped developer teams build dashboards, monitors, and other telemetry to understand whether their code is solving the business problem it was created for and whether their changes are moving the needle.

I am not a one-man show — I am a force multiplier. I can join an org, bring a fresh and curious can-do attitude, challenge assumptions, and help enable other engineers to deliver more reliably. If you want to move a mountain and have a good time while doing it, I am the right pick.

Work history.

Site Reliability Engineer II

Flywire Corp · New York, NY

Aug 2023 — Present

Owns reliability work that connects infrastructure architecture to business continuity: cloud connectivity, modernization, observability, and incident practices.

Architected hybrid cloud connectivity between on-premise systems and AWS using IPsec, BGP, and hub-spoke VPC design, enabling critical legacy workloads to move into ECS during a legacy infrastructure failure event.
Reduced annual infrastructure cost by 30%, decommissioned $250K in legacy infrastructure, and preserved $500K+ ARR by preventing disruption to revenue-critical systems.
Led modernization from legacy .NET to .NET 8.0+ and built CI/CD pipelines with ECR and CodeArtifact, helping decouple a code monolith into 20+ cloud microservices.
Reduced SRE manual intervention and deployment MTTR by >80% through modernization and pipeline improvements.
Migrated manually configured telemetry into Datadog with Terraform-based IaC, giving teams version-controlled monitoring across 400+ resources.
Defined incident metrics, SLO/SLA standards, and postmortem patterns that drove self-healing workflows and reduced repeated common incidents by 50%.

Senior Software Developer in Testing

FlexTrade Systems Inc. · Great Neck, NY

Oct 2021 — 2023

Built automation and validation tooling for trading workflows where release confidence, repeatability, and protocol correctness mattered.

Developed Ansible playbooks to provision and manage 20+ Linux environments for testing and development in on-premise infrastructure.
Built a custom .NET regression testing framework using Algowheel routing and C++ APIs for configurable rule execution.
Automated 800+ manual test cases, reducing testing time by 12 hours per week and improving release-cycle reliability.
Developed an internal ATDL testing tool to validate FIX protocol and platform standards, then extended it for client-facing validation of critical trading workflows.

Education

Physics trained the way I debug systems.

B.S. Physics, cum laude

The City College of New York

Focus: quantum computing, numerical methods, and systems reasoning.

That background still shows up in my engineering: isolate the variables, write down the model, test the boundary cases, then automate what should never be manual twice.

Selected projects

Quantum & numerical work.

Quantum Phase Estimation with Qiskit

Phase estimation, periodicity finding, and the algorithmic ideas behind Shor's algorithm.

Python Quantum Compiler

Matrix operators, multi-qubit gates, measurement routines, and circuit execution ideas in Python and NumPy.

Next step

For infrastructure, reliability, and automation roles.

I am easiest to evaluate through the resume, GitHub, and LinkedIn links below. The short version: I move systems from fragile to observable, repeatable, and cheaper to operate.
