Scalability and performance review
Infrastructure cost analysis
Technical Due Diligence
Pre-acquisition code review
Technology risk assessment
Team capability evaluation
Tech Debt & Roadmap

Sound familiar?
You inherited a codebase and aren't sure what's sound and what's a liability
Your system works today but you don't know if it'll handle 10x the load
You're evaluating an acquisition and need an independent technical assessment before closing
Your engineering team says they need 6 months to refactor but can't explain what specifically needs to change or why

Architecture reviews follow a structured methodology. We review code, infrastructure, processes, and team structure - then deliver a written report with findings ranked by business impact.
We define review scope, sign NDAs, and get read access to repositories, infrastructure, CI/CD, and monitoring. We interview key engineers and review documentation. Typical setup takes 2-3 days.
Senior engineers review architecture patterns, code quality, test coverage, deployment pipeline, security posture, and infrastructure configuration. We stress-test scalability claims and quantify tech debt.
We deliver a written report with findings categorized by severity and business impact. Each finding includes a specific remediation recommendation with effort estimate. We present the report to your leadership team and answer questions.
Review outcomes
Using solutions such as React Native, Flutter, AWS, and many others makes it possible for us to upgrade your product as much as possible and to achieve a thriving collaboration. Here you will find our guide through our most used technologies and case studies related to each one.

Frequently asked questions
Senior engineers and architects with 10+ years of experience. The review team is matched to your technology stack. Every review is led by a principal-level engineer who has built and scaled production systems.
Read access to source code repositories, CI/CD configuration, infrastructure-as-code, monitoring dashboards, and any existing architecture documentation. We also request 2-3 hours of interviews with key engineers. All access is covered by NDA.
A penetration test focuses on security vulnerabilities. An architecture review assesses the entire system: scalability, maintainability, reliability, cost efficiency, team productivity, and security posture. We cover security as part of the review but the scope is broader.
Yes. We've supported pre-acquisition technical assessments for investors and acquirers. The deliverable includes technology risk assessment, team evaluation, tech debt quantification, and a post-acquisition integration roadmap. We work within deal timelines.
You receive a written report with prioritized findings. Many clients engage CoreLine to implement the recommendations - either as a standalone remediation project or as an ongoing engineering partnership. But the report is designed to be actionable regardless of who does the work.
