● Modernized the Eclipse RCP-based Bedrock application by upgrading to Eclipse e4 4.23, reducing legacy framework debt and unblocking remediation of 100+ long-standing CVEs that could not be resolved on the older stack. ● Streamlined development and release workflows after the Bedrock modernization, helping the team move from quarterly releases to monthly releases. ● Built cardinality and data-integrity reporting for healthcare data migrations from legacy systems to cloud-native services on OCI, identifying inconsistent data across 30+ tables during beta-client onboarding. ● Enabled earlier detection of migration data issues, allowing clinical and platform teams to assess impact and define mitigation steps before wider rollout. ● Created T2 metrics, OCI alarms, dashboards, and automated alarm-to-ticket workflows to improve operational visibility and incident response for migration reporting services. ● Partnered with clinical stakeholders and platform engineers to investigate data discrepancies, validate migration outcomes, and resolve production queries. ● Worked with Micronaut-based backend services while contributing to migration reporting, observability, and platform modernization.

● Owned and led end-to-end API integrations for 5 insurers, including Acko and National Insurance Company (NIA), across quote, KYC, IDV, and policy workflows, covering workflow discovery, requirements alignment, partner coordination, API contract design, implementation planning, and production readiness. ● Acted as the technical point of contact for insurer integrations by explaining workflows to external teams, capturing partner requirements, resolving integration gaps, and converting business flows into API designs. ● Implemented CKYC integration using CERSAI, enabling KYC details to be fetched in under 20 seconds compared with approximately 2 days through document-upload-based OVD verification. ● Added OVD verification using Protean APIs, reducing average OVD verification time from about 2 days to approximately 4 hours and automating verified-detail handoff to insurer systems. Reebu Mukherjee | Page 2 ● Owned the insurance connector service, which served as the gateway between PhonePe backend systems and insurer APIs for quote, KYC, IDV, policy, and verification workflows. ● Owned the pricing service and optimized quote retrieval by caching the first quote, reducing quote-page p99 latency to below 2 seconds. ● Owned the catalog service and built Elasticsearch-backed catalog APIs containing millions of car, model, year, and PIN-code combinations per insurer for motor-insurance quote workflows. ● Designed and owned custom Insured Declared Value (IDV) functionality for vehicle insurance workflows, making it backward-compatible with older versions of the PhonePe app. ● Worked with Data Builder, PhonePe's internal framework for creating state machines. ● Worked with Foxtrot, PhonePe's internal event-ingestion service, to record customer journeys across motor insurance workflows. ● Worked on Dropwizard-based backend services supporting insurance platform integrations and high-traffic quote APIs.

● Solely owned and developed the company-wide survey, notification, and reporting system used across approximately 30 Narayana Health hospitals, 20 other hospitals, and 2 UAE hospital groups. ● Scaled the survey platform to serve an average of approximately 500 surveys per day per hospital, with daily notifications and reports generated through cron-based background jobs. ● Designed and developed the complete patient feedback and survey platform using Spring Boot, REST APIs, PostgreSQL, MongoDB, and scheduled processing. ● Built analytics dashboards used by Narayana Health to monitor patient responses, feedback trends, survey performance, and hospital-level insights. ● Designed relational and NoSQL data models for feedback, surveys, analytics, notification status, issue tracking, and hospital workflows. ● Built a custom ticket-management system to track patient issues raised during surveys and support hospital follow-up workflows. ● Built a communication orchestrator module using AWS and Spring Boot to communicate with patients across multiple channels and automate feedback notifications. ● Implemented role-based authentication and authorization for hospital staff workflows using Spring Framework. ● Implemented Single Sign-On (SSO) using Azure Active Directory for secure hospital-staff access. ● Mentored junior engineers on TDD, Git, code quality, debugging, and version-control practices.

Coordinated with other engineers on migration of legacy software to cloud by breaking them into Mircoservices using RESTful APIs. Reviewed project specifications and designed technology solutions that met or exceeded performance expectations. Designed and implemented Interoperability between EHRs using FHIR API. Worked on enabling CORS filtering in our APIs. Delivered unit-tested systems with required characteristics and within customer-prescribed timeframes. Wrote highly maintainable, solid code to enable black box testing, forming core framework and earning consistent praise from subsequent developers since initial version. Driven full development cycle from requirement gathering, design, implementing code, white box testing and black box testing and demoing and delivering feature to clients.
