Architect Systems That Scale With Confidence
We design technical architectures that handle real-world load, evolve with your business, and don't fall apart at 3am when traffic spikes — because we've been there.
Trusted by innovative teams worldwide
Architects With Proven Credentials
Our architects hold the industry's most rigorous certifications — because architecture mistakes are the most expensive to fix.
Architecture Design for Systems That Actually Get Built
We produce architecture that engineers can implement — not ivory-tower diagrams that sit in a drawer.
System Architecture Design
High-level and detailed architecture documentation — component diagrams, data flows, integration patterns, and deployment topologies using C4 model and UML standards.
Microservices & Domain Design
Domain-driven design workshops to identify bounded contexts, service boundaries, and communication patterns — avoiding the distributed monolith trap that plagues most microservices adoptions.
Event-Driven Architecture
Design of event sourcing, CQRS, and message-driven systems using Kafka, RabbitMQ, or cloud-native services — for systems that need real-time processing and eventual consistency.
Security Architecture
Zero-trust network design, authentication/authorization patterns, encryption strategies, and compliance-ready security controls built into the architecture from the start.
Performance & Capacity Planning
Load modeling, capacity forecasting, caching strategies, and database sharding designs — so your architecture handles 10× growth without a rewrite.
API & Integration Architecture
REST, GraphQL, gRPC — we design API strategies with versioning, rate limiting, and partner integration patterns that scale cleanly as your ecosystem grows.
Building Something That Needs to Scale?
Talk to our architects before writing the first line of code.
Architecture designed for where you're going, not just where you are.
We design systems that handle 100× growth without architectural rewrites — saving you the most expensive engineering decision: starting over.
Architecture That Engineers Love to Build On
Good architecture makes engineering easier, not harder. We design systems that are intuitive to work with, easy to debug, and straightforward to extend — not over-engineered abstractions.
Why Engineering Teams Trust Our Architecture Work
We're architects who still write code — so our designs are practical, not theoretical.
Describe Your Architecture Challenge
Share your system context and we'll provide an initial architecture perspective within 48 hours.
Our Engagement Process
Context & Constraints
Understanding your business domain, scale targets, team capabilities, timeline, and non-negotiable constraints.
Architecture Design
Iterative design sessions producing C4 diagrams, ADRs, data models, and integration specifications.
Spike Validation
Proof-of-concept development for high-risk architectural decisions — validated with real load and data.
Documentation & Review
Complete architecture package: diagrams, decision records, implementation guides, and deployment topologies.
Handoff & Support
Engineering workshops, Q&A sessions, and 4 weeks of architecture advisory during initial implementation.
What Our Clients Say
“OpenMalo designed our payment processing architecture to handle 50K transactions per second. When we hit that number 18 months later, the system didn't flinch. That's the kind of foresight you can't put a price on.
“We were about to build a microservices architecture with 30+ services for a team of 8 engineers. OpenMalo talked us into a modular monolith instead. It was the best architecture decision we ever made — we shipped 4 months faster.
“Their event-driven architecture design for our real-time trading alerts platform was exceptional. The C4 documentation was so thorough that our junior engineers could understand the system within their first week.
50K Transactions Per Second — Zero Architecture Rewrites
Payment Processing Architecture for SwiftPay
How we designed a payment processing system that scaled from 2K to 50K transactions per second over 18 months without a single architectural change.
Outgrowing an architecture designed for a different era
SwiftPay's existing monolithic payment system was hitting performance ceilings at 2K TPS. Their customer base was growing 10× and the current architecture couldn't keep pace without constant firefighting.
Our Approach: Event-driven architecture with Kafka for transaction streaming, CQRS pattern separating read/write workloads, database sharding strategy with consistent hashing, and PCI-DSS compliant network segmentation — all documented in C4 model with implementation guides.
