Duration Typically 1–2 weeks depending on scope, with a final report and a roadmap. Fast-track option available for urgent cases.
Format For your codebase
Primary deliverable Written architecture report (~30 pages) — system map, identified risks, prioritised recommendations, trade-off analysis
Best for CTOs and engineering leaders who need an objective architecture assessment before scaling, replatforming, hiring growth, or investor conversations.

Outcome of this engagement

A 30-page written report on your architecture risks — with a prioritised roadmap your team can execute in the next quarter.

What you receive

  • Written architecture report (~30 pages) — system map, identified risks, prioritised recommendations, trade-off analysis
  • 60-minute walkthrough call — we present findings to your team and answer questions
  • Slide deck of the same findings — for sharing with stakeholders, investors, or your board
  • Written summary email — a 1-page executive version of the report for non-technical readers
  • Optional follow-up session 4 weeks later — review what your team executed and where to go next

Is this service the right fit for you?

Book this if you…

  • You're a CTO or head of engineering with a 50k+ LoC codebase that "still works but is starting to feel slow" — and you want a senior outside opinion before the next big architecture decision
  • You're raising a Series A/B and an investor or technical advisor has asked for an independent technical assessment
  • You're about to scale the team 2-3× and want to know which architectural decisions to make NOW, before more engineers cement the wrong ones

Don't book this if you…

  • You want us to BUILD the system — this is a review service, not a delivery one. We hand you a roadmap; your team executes it
  • Your codebase is under 5k LoC — there's not enough surface area to review meaningfully. Spend the budget on building features instead
  • You want validation, not feedback — if you're looking for a stamp of approval to silence a sceptic, this isn't the right engagement. We say what we actually find

Why This Service

Architecture issues rarely fail loudly — they fail through slow delivery, hidden risks, and rising costs. We provide an external, senior-level review with actionable improvements and prioritization that teams can execute.

Key Benefits

1

Risk & Bottleneck Identification

Find architectural risks that impact reliability, scaling, security, and delivery speed.

2

Actionable Architecture Roadmap

Prioritized steps with trade-offs, effort estimates, and sequencing your team can follow.

3

Alignment Across Stakeholders

Create a shared understanding of what to fix now vs later — and why.

4

Higher Confidence for Scaling

Reduce surprises during growth by validating architecture decisions early.

What This Service Includes

  • Architecture and system design review (services, data, boundaries)
  • Scalability, reliability, and security risk assessment
  • Performance and operational bottleneck analysis
  • Final report with prioritized recommendations and next steps
  • Optional follow-up session to align execution plan

Currently leads architecture for ToyCRM.com — a multi-tenant CRM platform built on .NET by our team. The same patterns and design decisions used there appear directly in the courses: identity & auth, distributed services, code review culture. You learn from engineers actively shipping production code, not from a textbook.

Companies with engineering bandwidth sometimes prefer to upskill the team rather than buy the engagement. If that's you, here are the courses that cover the same ground — taught by our senior engineers in the same voice as our consulting work:

Architecture Review for Scalable and Reliable Systems

Professional architecture review by our senior engineering team with deep production experience. Identify risks, scalability issues, and improve system design before they become costly problems.

Architecture decisions made early in a project often determine its long-term success or failure. Our architecture review service is designed to provide an independent, senior-level assessment of your system before technical debt, scalability limits, or reliability issues become expensive to fix. We review architecture from a production mindset, focusing on real traffic, real data, and real operational constraints.

During the architecture review, we analyze system boundaries, service responsibilities, data flows, and integration points. Special attention is paid to scalability, fault tolerance, security, performance bottlenecks, and operational complexity. We evaluate whether the chosen architecture—monolith, modular monolith, or microservices—fits your business stage and team maturity, rather than following trends blindly.

Our reviews go beyond diagrams. We examine real code structure, API contracts, database design, authentication and authorization flows, caching strategies, and deployment pipelines. The goal is to identify architectural risks early, highlight hidden coupling, and surface design decisions that may slow down delivery or increase operational costs over time.

The outcome of the architecture review is a clear, actionable report. You receive concrete recommendations, prioritized by impact and effort, along with trade-off explanations. This allows engineering leaders and teams to make informed decisions, improve system resilience, and plan future evolution with confidence.

What's Included

  • Independent architecture review by our senior engineering team
  • Scalability, reliability, and security analysis
  • Monolith vs microservices trade-off evaluation
  • Codebase, API, and database design assessment
  • Production and operational risk identification
  • Actionable recommendations with clear priorities

What You'll Achieve

  • Identify architectural risks before they become costly
  • Improve scalability and system reliability
  • Reduce future technical debt
  • Make informed architecture and technology decisions
  • Align system design with business goals
