DISTRIBUTED MICROSERVICES DEVELOPMENT
We architect fault-tolerant Node.js & Go microservices, event-driven API gateways, distributed database clusters, and zero-downtime cloud infrastructure.
Backend & Cloud Capabilities
Distributed Microservices & gRPC
Decoupled, high-throughput microservices communicating over gRPC, Protocol Buffers, and REST APIs for sub-millisecond inter-service latency.
- High-concurrency Go & Node.js Services
- gRPC & Protobuf Binary Serialization
- API Gateway Routing & Rate Limiting
Database Optimization & Caching
PostgreSQL query optimization, Redis multi-layer caching, connection pooling, and automated database sharding for heavy read/write workloads. Feed your data into enterprise AI agents and RAG systems.
- PostgreSQL Master-Replica Clusters
- Redis Cluster Cache Invalidation
- 📊 TimescaleDB & ClickHouse Analytics
DevOps & Kubernetes Infrastructure
Automated Terraform IaC, Docker containerization, Kubernetes autoscaling (KEDA), and continuous GitHub Actions zero-downtime deployment pipelines. Run high-performance web platforms on top of it.
- ☁️ AWS EKS / GCP Kubernetes Autoscaling
- 🛠️ Terraform Infrastructure as Code
- Zero-Downtime Blue-Green Deployments
Every Platform Includes
100% Code & IP Ownership
Full source code and intellectual property transferred to you. Zero vendor lock-in, ever.
Technical Documentation
Architecture specs, API references, and handover guides your team can actually use.
CI/CD Automation
Automated testing pipelines and zero-downtime deployments baked into every sprint.
24/7 Support & SLA
Uptime guarantee, proactive monitoring, and priority access to senior engineers.
Monolithic Legacy Backend vs. ZAVA Microservices
Why enterprise platforms trust ZAVA for high-concurrency cloud systems.
| Infrastructure Metric | Legacy Monolithic API | ZAVA Distributed Microservices |
|---|---|---|
| Peak Concurrency Capacity | ✖ Bottlenecked (< 2,000 req/sec) | ✔ 50,000+ Req/Sec Auto-Scaling Go/Node |
| API Response Latency | ✖ 250ms - 800ms Laggy REST | ✔ < 15ms Sub-ms gRPC Protobuf Streams |
| System Reliability & Uptime | ✖ Frequent Outages Single Node | ✔ 99.99% SLA Multi-Region Active Cluster |
| Deployment Risk | ✖ Single Point Failure Monolith | ✔ Zero-Downtime Blue-Green K8s Rollout |
| Database Performance | ✖ Lock & Slow Queries Single DB | ✔ Postgres Sharding Redis Cluster Cache |

How do you handle database failover and data integrity?
Trusted by Builders
They took us from a fragile monolith to a Kafka-backed service mesh handling 50K+ requests per second. Failovers are now invisible to our users.
The active-active Postgres setup and automated failover they built has held 99.99% uptime across two regions for over a year.
Kubernetes autoscaling with zero-downtime deploys was the hardest part of our stack, and they made it boring. That is exactly what you want.
