Experience
9+ years across healthcare, retail e-commerce, enterprise SaaS, and medical-device tooling — Tech Mahindra → HCL → BCG → Foray → Cibronix.
- Leading the migration of a legacy Oracle ADF healthcare claims platform to Spring Boot REST APIs + a React/TypeScript front-end — strangler-pattern rollout, zero downtime.
- Architecting microservices around regulated claim formats (HCFA-1500, UB-04); async messaging alongside synchronous REST inter-service comms.
- Established Jenkins CI/CD with build/test/deploy stages and OWASP-aligned secure coding standards.
- Pair-programming with Claude Code and GitHub Copilot in daily development.

- Architected Spring Boot microservices for a multi-tenant SaaS supplier data platform handling 50K+ daily transactions.
- Designed and built a GraphQL Federation layer unifying 8 microservices — cut API payloads by 60% and response times by 40%.
- Implemented Apache Kafka event-driven workflows at 100K+ messages/day with consumer groups and dead-letter queues — zero message loss.
- Built the React + Next.js front-end in TypeScript at 80% test coverage; containerised on Docker + Kubernetes with Buildkite CI/CD.

- Led a cross-functional team of 5 engineers delivering Alloc AI — BCG's AI-driven marketing budget allocation platform, successor to Marketing Catalyst's Strategic and Tactical modules.
- Designed FastAPI services and complex D3.js visualisations powering the client-facing analytics layer.
- Cut data processing time by 66% (21 → 7 days) via optimised Python pipelines and event-driven microservices.
- Implemented GraphQL Federation as a unified API gateway bridging Java and Python services.

- Built the Node.js SSR layer for the Under Armour Progressive Web App on Mobify's PWA Kit (later acquired by Salesforce as Headless Storefront).
- Integrated against Salesforce Commerce Cloud (SFCC) via OCAPI for catalog, cart, customer, and checkout flows.
- Tuned the SSR layer for retail performance — response caching, request batching, lazy-loading — kept p95 TTFB tight during traffic spikes.
- Earlier in the role: designed a CVE remediation microservice framework for HCL × Symantec — Spring Boot + RabbitMQ-coordinated workflows + Angular front-end for security analysts.

- Built end-to-end across mobile, web, and back-end for a medical-device sales-enablement configurator — field reps used it on-site at hospitals to design anesthesia machines, calculate pricing, and email specs to prospects.
- Shipped Java back-end services for the configuration domain alongside a Node.js + Express API/BFF layer.
- Built the Angular (TypeScript) web client and Ionic/Cordova hybrid mobile client against a shared configuration model.
- Designed PostgreSQL schemas tracking quote history and configuration versions per customer; JWT auth + role-based access for sales hierarchy.
