We Build Scalable Backends forAI & SaaS Startups
Production-ready systems that scale — with backend, cloud, and product execution handled end-to-end
We help funded and pre-scale startups design, build, and stabilize backend, cloud, and data architectures using AWS, Kafka, and AI-driven workflows.
How We Work
A technical risk reduction framework to build production-grade systems that scale
We don't just design systems — we ship complete, production-ready web and mobile applications used by real customers.
1. Assess
Architecture & infrastructure audit. We analyze your current system, identify bottlenecks, and assess scalability risks before building.
2. Design
Scalable system design. We architect backend systems using event-driven patterns, microservices, and cloud-native principles.
3. Build
Production-grade backend development. We build robust systems using AWS, Kafka, and modern frameworks that handle real-world scale.
4. Stabilize
Monitoring, cost optimization, and performance tuning. We ensure your system stays reliable, cost-effective, and performant as you scale.

Case Study
How we solved a critical backend scaling challenge
Scaling an AI Product: Event-Driven Backend + Production UX
The Challenge
An AI startup was experiencing backend failures as their platform scaled. Their monolithic architecture couldn't handle the increasing load from AI inference requests, and database bottlenecks were causing 40% request timeouts during peak hours.
The Solution
We redesigned their backend using an event-driven microservices architecture:
- Migrated to AWS Lambda + API Gateway for serverless request handling
- Implemented Kafka for event streaming between AI inference services
- Replaced relational database with DynamoDB for high-throughput data access
- Built async processing pipeline for long-running AI workflows
- Added comprehensive monitoring with CloudWatch and distributed tracing
The Results
"The new architecture handles 10x the traffic with better reliability and lower costs. We can now focus on product features instead of fighting fires." — CTO, AI Startup
