Our Capabilities
Architecture Assessment
We perform comprehensive architecture assessments that reveal the true state of your system — not just what the documentation says, but how the code actually works in production. Our assessment covers application architecture (module boundaries, coupling, cohesion, separation of concerns), database design (normalization, indexing strategy, query patterns, growth projections), infrastructure architecture (deployment topology, scaling capabilities, single points of failure), security architecture (authentication flows, authorization models, data encryption, API security), and operational readiness (monitoring, alerting, logging, backup, disaster recovery). The deliverable is a detailed Architecture Health Report with severity-rated findings and a prioritized remediation roadmap. Most assessments reveal 3–5 critical issues that, left unaddressed, would cause significant problems within 6–12 months. Typical assessment duration: 1–2 weeks.
System Design
We design system architectures for new projects or major rebuilds — ensuring the foundation supports your current requirements and future growth without over-engineering. Our design process follows a structured methodology: requirements analysis (functional, non-functional, constraints), architecture decision records (ADRs) documenting key trade-offs, component diagrams showing service boundaries and communication patterns, data flow diagrams mapping how information moves through the system, deployment diagrams defining infrastructure requirements, and technology selection rationale with alternatives considered. We specialize in event-driven architectures for real-time systems, CQRS (Command Query Responsibility Segregation) for high-read/write workloads, domain-driven design for complex business domains, and hexagonal architecture for testable, maintainable codebases. Every design includes capacity planning estimates so you know exactly what infrastructure you'll need at 10x and 100x current scale.
Microservices Strategy
We help organizations design and implement microservices architectures that deliver on the promise of independent deployment, team autonomy, and selective scaling — without falling into the common traps (distributed monolith, data consistency nightmares, operational complexity explosion). Our microservices strategy includes domain analysis using bounded contexts to define service boundaries (the most critical decision in any microservices project), communication patterns selection (synchronous REST/gRPC for queries, asynchronous events for state changes), data management strategy (database per service, eventual consistency, saga patterns for distributed transactions), API gateway design for routing, rate limiting, authentication, and request aggregation, and observability architecture (distributed tracing with Jaeger/Zipkin, centralized logging with ELK, metrics with Prometheus/Grafana). We're pragmatic about microservices: not every system needs them. For many applications, a well-structured modular monolith is the right architecture. We'll recommend what's best for your specific situation, team size, and growth trajectory.
Performance Architecture
We design systems for performance from the ground up — because retro-fitting performance into a poorly architected system is 10x more expensive than building it right the first time. Our performance architecture work includes caching strategy design (CDN, application cache, database query cache, session cache) with invalidation patterns that ensure data freshness, database architecture for high-throughput workloads (read replicas, connection pooling, partitioning, materialized views), asynchronous processing architecture for offloading heavy operations (email sending, report generation, image processing, data imports) to background workers, auto-scaling architecture that responds to traffic patterns within 60 seconds, and content delivery architecture for global applications serving users across multiple continents. We establish performance budgets early in the project (e.g., P95 API response < 200ms, page load < 2s on 3G) and design architecture that meets these targets at projected scale.
Technology Selection
Choosing the wrong technology stack costs months of development time and years of accumulated technical debt. We provide objective technology selection consulting based on your specific requirements — not vendor relationships or personal preferences. Our evaluation criteria include team expertise and hiring market (can you find developers for this technology in your market?), maturity and community support (is this technology production-proven or bleeding-edge?), performance characteristics (does it handle your workload pattern efficiently?), scalability ceiling (where does this technology break down?), total cost of ownership (licensing, infrastructure, developer productivity, maintenance burden), and ecosystem (libraries, tools, integrations available). We provide a Technology Selection Report comparing 2–3 viable options with detailed trade-off analysis, sample implementations, and a clear recommendation with reasoning.
Cloud Architecture
We design cloud architectures on AWS, Azure, and GCP that balance performance, cost, security, and operational simplicity. Our cloud architecture work includes network design (VPC topology, subnet strategy, security groups, NAT gateways, VPN/Direct Connect for hybrid setups), compute strategy (containers vs serverless vs VMs, right-sizing, reserved vs on-demand vs spot), storage architecture (object storage, block storage, file systems, data lifecycle policies), security architecture (IAM policies, encryption, secrets management, WAF, DDoS protection), disaster recovery design (multi-AZ, multi-region, RPO/RTO targets, failover automation), and cost optimization (reserved instances, savings plans, spot instances, auto-scaling, storage tiering). Every cloud architecture includes a cost projection model so you know exactly what you'll spend at current and projected scale.

Frequently Asked Questions
Key indicators: planning a new complex system, experiencing scalability issues, high technical debt, preparing for growth, migrating to microservices, or moving to the cloud. Architecture consulting prevents costly mistakes and ensures your system can evolve with your business.
Microservices architecture decomposes an application into small, independently deployable services. Each service owns its data and communicates via APIs. Benefits include independent scaling, technology flexibility, faster deployments, and team autonomy.
An architecture assessment takes 1-2 weeks. A complete architecture design for a new system takes 2-4 weeks. Ongoing architecture guidance is typically provided as part of the development engagement.
Start with a well-structured monolith for new projects — it's simpler and faster. Move to microservices when you have clear scaling needs, multiple teams, or specific services that need independent deployment. We help you make the right choice for your situation.
Yes, we don't just design architectures — we implement them. Our architects work alongside development teams to ensure the architecture is properly implemented, and we provide ongoing guidance as the system evolves.
