Case Studies

Multi-Agent Clinical AI Platform

Healthcare / MedTech · AI Systems Engineering

500ms first-response latency — Down from 12 seconds. SaMD compliance achieved.

Decomposed monolithic LLM into a LangGraph topology: retrieval agent (pgvector), planning agent, generation agent, verification agent. Parallel node execution. SSE streaming at output boundary. FHIR R4 integrated. Sub-0.1% hallucination rate enabled SaMD compliance sign-off.

National-Scale GitOps on Oracle Cloud

Government / Public Sector · Cloud Infrastructure & DevOps

60% deployment lead time cut — Rollback reduced to a 3-second git revert.

Full GitOps architecture on Oracle OKE: GitLab CI for versioned Helm releases, ArgoCD for continuous reconciliation. Terraform IaC with least-privilege IAM. Full observability: Prometheus, Grafana, ELK, Loki. OCI Vault secret management. Zero-credential exposure.

Industrial Cold-Chain IoT Platform

Cold-Chain Logistics · Industrial IoT & Real-Time Systems

Zero data loss at 4,000+ nodes — Sub-2s end-to-end latency. 99.9% uptime SLA.

Dual-persistence architecture: SQLite hot path, InfluxDB cold path with native downsampling. HTTP polling replaced with WebSocket persistent connections. Sensor failure treated as normal case — buffered reconnection and replay. Alert logic on data absence, not just anomalies.

AWS Cloud Cost Optimization

Enterprise / Cloud Cost Engineering · Cloud Infrastructure & DevOps

25% total spend reduction — Zero application code changes. All Terraform-managed.

Four-phase engagement: Visibility (tagging + Cost Explorer), Right-sizing (28 of 34 EC2 candidates), Reserved Instances (RDS + EKS node groups), Storage hygiene (S3 lifecycle, 847 orphaned EBS snapshots eliminated). Every change through CI/CD with full rollback.

QA Automation Transformation

Enterprise SaaS · QA Automation & Quality Engineering

4 days → 22 minutes regression — 3 production regressions caught in first sprint.

Automated 80% of critical-path flows with Playwright (Python), parallelized headless, Jenkins CI integrated. Appium for iOS and Android. Postman/REST Assured for API contracts. JMeter/k6 for performance baselines. Results in PR before merge. 40 engineers unblocked.

Server-Side Tracking Infrastructure

E-Commerce / Performance Marketing · Data Analytics & Server-Side Tracking

30–45% cost-per-lead reduction — Attribution data loss eliminated. Signal quality restored.

Server-side GTM container with direct Facebook CAPI integration — eliminating browser-side dependency. GA4 event taxonomy rebuilt from scratch. Cross-channel attribution in GA4 Explorations and Looker Studio. Meta campaign restructure on verified signal quality.
