Principal Member Of Technical Staff

Oracle
May, 2024 - Present1 yr 8 months
    Architected and led the development of Clinical Data Exchange Hub, a multi-tenant, cloud-native, event-driven SaaS application enabling secure, centralised medical data sharing across 500+ healthcare providers, reduced report turnaround time from days to near real time. Led the design and development of a high-throughput data plane management service to process multi-GB CSV/NDJSON datasets and ADT events from AWS S3 and OCI Queues. Designed partitioned, parallel processing pipelines integrating with Oracle HIE/Millennium/HDI systems, delivering near real-time demographic survey reports to customers via S3 and secure SFTP. Architected and implemented an inbound service to reliably process high-volume ADT (Admission/Discharge/Transfer) events from Millennium EHR, streaming them into OCI Queues. Achieved fault-tolerant ingestion of millions of healthcare records daily, enabling downstream analytics and compliance workflows. Developed a low-latency outbound service using reactive stream architecture and non-blocking I/O to concurrently deliver patient data to multiple payer systems. Reduced end-to-end delivery latency by 70%, ensuring real-time data exchange and compliance with payer interoperability mandates. Designed and led development of the Clinical Data Exchange Hub - a control plane service that enables self-serve configuration of payer/provider endpoints for secure query and delivery. This innovation eliminated manual provisioning, cut onboarding time from weeks to hours, and became a core differentiator for Oracles healthcare data exchange platform.

Senior Java Engineer

Deel
Aug, 2023 - Apr, 2024 8 months
    Developed and deployed the Chargeback Deflector microservice, a backend component that automatically handles chargeback reversals from the Ethoca gateway, reducing manual intervention and payment loss in renewal workflows. Designed and implemented the Add Credit Card feature for Prime users, improving user experience for repeat bookings and simplifying subscription renewals using CQRS pattern and A/B testing. Led the design and development of a new commerce rollout for the U.S. market, integrating with Worldpay for subscriptions under $10, enabling expansion into a new geography using A/B testing and Canary deployment.

Senior Member Of Technical Staff

Vmware
May, 2021 - Aug, 20232 yr 3 months
    Led architecture and development of vRealize Cloud Subscription Manager, a multi-tenant, distributed SaaS platform managing end-to-end subscription lifecycle (order intake, onboarding, service activation). Applied Event Sourcing and Saga patterns to ensure resilience and consistency at scale, enabling seamless onboarding of thousands of enterprise customers and retiring VMwares legacy licensing model. Designed and implemented a Facade Service to orchestrate subscription onboarding workflows and expose APIs for UI-driven order management. Built a scalable subscription service to automate activation of bundled services across multi-cloud environments, ensuring error-free provisioning at scale and removing manual activation effort for ops teams. Architected a low-latency Orchestrator to execute complex service activation workflows, applying rule-based execution per service type. Optimised for concurrency and throughput, the system reduced activation time from hours to minutes while ensuring compliance with subscription SLAs. Designed and developed installation, upgrades, and scaling (horizontal/vertical) process for VMware vRealize Suite (vROps, vRA, vRLI, vRNI, cloud proxies) via state-machine patterns and vCenter APIs, cutting installation/upgrade time by 40% and reducing deployment failures by 30% through intelligent pre-checks - adopted across 100+ enterprise customer environments. Enhanced observability and resilience by integrating comprehensive telemetry (logging, metrics, alerts, dashboards) with CloudWatch, Wavefront, PagerDuty, and Slack notifications. Improved MTTR by 35% and enabled proactive incident response across production environments.
