# Enterprise Services Portfolio - QuantZent

QuantZent provides high-reliability engineering services, infrastructure retainers, and automation solutions tailored for mid-market and enterprise organizations.

## 1. Cloud Services & FinOps Audits
- **AWS & Azure Infrastructure Management:** Enterprise cloud architecture provisioning, Infrastructure as Code (Terraform), and container orchestration (Amazon EKS, Azure AKS).
- **FinOps Cost-Reduction Audits:** Comprehensive analysis of unattached EBS volumes, oversized compute instances, untagged assets, and reserved instance / savings plans optimization, reducing monthly cloud bills by an average of 38%.
- **Zero-Downtime Migration:** Migration of on-premises workloads to hybrid or multi-cloud topologies with automated fallback pipelines and multi-region replication.

## 2. Enterprise JVM Support Retainers
- **Strict SLA Retainers:** Guaranteed 15-minute response times for critical P1 production incidents on Kotlin, Java, and Spring Boot production deployments.
- **Legacy Monolith Modernization:** Incremental decomposition of legacy Java 8/11 monoliths into lightweight microservices using Spring Boot 3 and Kotlin.
- **Garbage Collection & Latency Profiling:** In-depth JVM diagnostics utilizing async-profiler and JFR to eliminate GC stop-the-world pauses and optimize off-heap memory consumption.

## 3. Enterprise .NET Support & Architecture Scaling
- **L2 / L3 Mission-Critical Support:** Around-the-clock incident triage, bug fixing, and patching for production .NET Framework and .NET Core applications.
- **Legacy Framework Migration:** Upgrades from legacy .NET Framework 4.x to modern cross-platform .NET 8/9 runtimes with Linux containerization.
- **Distributed Systems Scaling:** Refactoring monolithic relational persistence layers with asynchronous messaging (RabbitMQ, Azure Service Bus) and Redis caching layers.

## 4. Agentic AI Enterprise Workflows
- **Autonomous Corporate Workflows:** Multi-agent autonomous pipelines orchestrating complex, unstructured enterprise business processes without human intervention bottlenecks.
- **Automated Invoice & Purchase Order Reconciliation:** Automated ingestion, extraction, and validation of multi-format accounts payable invoices, cross-referencing with purchase orders and 3-way matching in enterprise ERPs (SAP, NetSuite, Tally).
- **Audit Trails & Security Controls:** Deterministic human-in-the-loop escalation thresholds with cryptographically verifiable audit ledgers.

## 5. Corporate Hardware AMCs & Device-as-a-Service (DaaS)
- **IT Annual Maintenance Contracts (AMCs):** Preventative maintenance, 4-hour on-site MTTR response, firmware hardening, and component replacement for enterprise compute and network fabrics.
- **Cisco & Dell Infrastructure Fleets:** Specialized hardware lifecycle management for Cisco Catalyst switches, Meraki edge devices, Dell PowerEdge rack servers, and Dell Precision workstations.
- **Device-as-a-Service (DaaS):** Turnkey edge workstation and laptop provisioning with pre-configured corporate security baselines, disk encryption, and automated lifecycle replacement every 36 months.

## Engagement Model
- **Infrastructure Audits:** Fixed-scope, two-week discovery and cost-reduction assessment.
- **Dedicated Monthly Retainers:** SLA-backed engineering capacity with dedicated technical account leads.
- **Project Engagements:** Milestone-driven architecture execution with deterministic deliverables.
