What the Review Covers

A comprehensive technical assessment across six architectural dimensions — nothing left unexamined.

System Design Review

Complete technical evaluation of your architecture against scalability targets, reliability SLAs, cost optimization, and performance benchmarks. We produce C4 model diagrams and a prioritised improvement backlog.

C4 Model DiagramsScalability AnalysisSLA BenchmarkingCost ModelingTech Debt Assessment

Infrastructure Planning

Cloud deployment strategy (AWS/GCP/Azure), containerization with Docker/Kubernetes, infrastructure-as-code blueprints, multi-region failover design, and disaster recovery planning.

Data Architecture

Database selection (SQL vs NoSQL), schema design patterns, caching strategies (Redis/Memcached), replication and sharding, data pipeline optimization, and event-driven data flows.

Security Assessment

Threat modeling, authentication/authorization patterns, encryption strategy at rest and in transit, compliance gap analysis (SOC2, HIPAA, GDPR), and vulnerability surface assessment.

Integration Design

REST/GraphQL API design, event-driven architecture patterns, message queue selection (Kafka, SQS, RabbitMQ), webhook systems, and third-party integration strategies with reliability patterns.

Delivery Roadmap

Sprint-level breakdown with milestones and decision points. Technical risks with likelihood/impact matrix and mitigation strategies. Resource estimates by phase. Phased delivery timeline with go/no-go gates.

How a Review Works

A structured 6-step process from discovery to delivery — refined across 250+ architecture reviews.

01

Requirements Deep-Dive

Two-hour structured session with your technical and business stakeholders to capture functional requirements, non-functional requirements (latency, throughput, availability SLAs), compliance constraints, and growth projections.

02

Current State Analysis

Review existing codebase, infrastructure configs, deployment pipelines, and any architectural documentation. Identify technical debt hotspots, scaling limits, and security gaps through static analysis and code review.

03

Architecture Design

Produce C4 model diagrams (Context, Container, Component, Code), sequence diagrams for critical paths, infrastructure diagrams, and data flow maps. Evaluate 2–3 architectural options with trade-off analysis.

04

Risk Assessment

STRIDE threat modeling, FMEA for critical components, dependency risk mapping, vendor lock-in assessment, and a prioritized risk register with CVSS-style scoring (likelihood × impact).

05

Technology Recommendations

Stack recommendations with pros/cons comparison matrices, migration path from current state, vendor evaluation with scoring criteria, and cloud cost modeling across AWS/GCP/Azure.

06

Delivery Roadmap

Sprint-level delivery plan (typically 2-week sprints), team structure recommendations, hiring gaps, milestone definitions, and a fully documented architecture decision record (ADR) for each major choice.

Architecture Patterns We Apply

Battle-tested patterns for scalability, reliability, and maintainability — applied selectively to each system's unique requirements.

Microservices
Domain-bounded services with independent deployability
Event Sourcing
Immutable event log as source of truth
CQRS
Separate read/write models for scalability
Saga Pattern
Distributed transaction management
API Gateway
Single entry point with cross-cutting concerns
Service Mesh
Istio/Linkerd for traffic control & observability
Strangler Fig
Incremental legacy modernization pattern
BFF Pattern
Backend for Frontend per client type

Featured Architecture Review

Monolith-to-Microservices Migration Plan

Series B SaaS — HR Technology, 800K users

Architecture

Challenge

A 7-year-old Rails monolith struggling to scale past 10K concurrent users. Deployment took 45 minutes and any failure brought down the entire platform. Engineering team of 35 wanted to move to microservices but had no plan — and had already wasted $400K on a failed attempt.

Review Approach

5-day brownfield review analyzing 400K lines of Rails code, PostgreSQL schema (900+ tables), and infrastructure configuration. Produced C4 diagrams for current state and target state, identified 8 bounded contexts, designed strangler fig migration pattern with 18-month phased timeline.
