FLAGSHIP CASE STUDIES
VERIFIED SOURCE ARCHITECTURE
HakiOps — Multi-Tenant Enterprise AI Reliability SaaS Platform
Enterprise-grade AI reliability platform featuring a Go API Gateway, 20 internal Python AI microservices, Redpanda Kafka streaming, Vault security, and GitOps ArgoCD deployments.
System Architecture Concept
Four-tier decoupled architecture: React SPA -> Go API Gateway -> 20 Internal Python AI Microservices -> Infrastructure Stack (PostgreSQL, Redpanda, Neo4j, OpenSearch, Vault).
Problem Statement:
Enterprise AI workloads require isolated multi-tenancy, strict zero-trust boundary controls, distributed telemetry, and sub-millisecond API rate limiting.
Engineered Solution:
Built a dedicated Go API Gateway for edge verification while orchestrating 20 Python AI microservices behind strict network security boundaries with OpenTelemetry tracing.
Verified Outcomes
- Engineered sub-5ms JWT authentication at the Go API Gateway level.
- Isolated 20 internal Python AI microservices behind secure private bridge networks.
- Achieved 100% GitOps auditability with ArgoCD and Helm.
