Engineering Case Studies & Performance Benchmarks.
Real-world operational breakthroughs engineered by QuantZent. We evaluate the exact bottleneck, architect the replacement runtime or infrastructure, and hold ourselves accountable to measurable business metrics.
Mid-Market Logistics SaaS ($12M ARR)
Eliminating 38% AWS Spend via Automated Kubernetes Right-Sizing
Operational Bottleneck
Uncontrolled growth of EKS microservices across multiple AWS availability zones resulted in severe over-provisioning, unreserved on-demand EC2 usage, and an orphaned multi-TB EBS volume footprint inflating monthly cloud invoices past $42,000.
Engineered Solution & Architecture
Implemented Karpenter auto-scaling on AWS EKS with graviton-backed spot/on-demand orchestration. Engineered automated FinOps tagging policies with OpenTofu/Terraform, and converted underutilized RDS instances to Aurora Serverless v2.

FinTech Payment Gateway (Kolkata & Mumbai)
4.2x P99 Latency Acceleration via Kotlin & Virtual Threads
Operational Bottleneck
Legacy Java 8 monolithic backend experienced frequent 1,200ms stop-the-world garbage collection pauses during peak transaction windows. Blocking JDBC connection pools caused thread starvation and high transaction timeout rates.
Engineered Solution & Architecture
Migrated legacy payment routing services to Kotlin and Spring Boot 3 on JDK 21. Replaced thread-per-request blocking architectures with Java Virtual Threads (Project Loom) and tuned ZGC generational collectors with async-profiler memory analysis.

National Industrial Manufacturing Group
Reducing Invoice Processing Time from 4 Days to 11 Minutes
Operational Bottleneck
Finance teams processed over 3,500 supplier invoices monthly through manual data entry. Errors in GST tax invoice rates and mismatching against warehouse delivery challans led to delayed supplier payments and missed ITC claims.
Engineered Solution & Architecture
Engineered an autonomous multi-agent pipeline using deterministic LangGraph orchestration. Agents perform document layout extraction, automated 3-way matching against purchase orders and goods receipt notes, and direct programmatic entry into SAP ERP.

Healthcare Diagnostic Network (18 Facilities)
Zero Downtime via 4-Hour MTTR Dell & Cisco Enterprise AMC
Operational Bottleneck
A multi-city diagnostic network suffered from aging switch stacks and unmonitored Dell PowerEdge storage servers. A core switch failure previously resulted in an 18-hour outage across 6 regional labs with lost revenue and clinical report delays.
Engineered Solution & Architecture
Structured a comprehensive 24/7 Hardware Annual Maintenance Contract (AMC). Deployed cold-spare Cisco Nexus core switches, instituted automated SNMP health telemetry, and guaranteed on-site hardware dispatch with under 4-hour MTTR.
