Bengaluru, Karnataka, India

Hardened 15+ Node.js/TypeScript API flows on an enterprise insurance platform: parameterized MSSQL, structured logging, standardized errors, JWT middleware, and PII-safe logs. Delivered and refactored auth, user, policy, motor, and claims APIs; built admin CMS and reporting APIs for internal operations. Deployed Kubernetes workloads from AWS EC2 using kubectl apply; monitored rollouts, pod health, and logs with k9s.

Redesigned assignment re-upload with MongoDB bulkWrite, cutting database round-trips by 90% for 15K+ active learners. Optimized aggregation pipelines, reducing per-document memory from 145KB to 5KB and improving query throughput 5x. Owned Kafka producers/consumers across 21+ microservices (~100K events/day) with retries and dead-letter handling. Built a GraphQL Federation gateway integrating 20+ services; improved Kibana/Grafana observability and reduced production incidents by 60%.

Bengaluru, Karnataka, India · Hybrid

Designed the Science of Learning (SOL) backend from scratch (HLD/LLD): 6 microservices, a data access layer, and an API gateway, integrating legacy systems with new FLN features. Built offline-first sync and conflict resolution for 10K+ learners using MongoDB, Redis, and MongoDB Realm so assessments worked in low-connectivity classrooms. Shipped the SOL React Native app (voice assessments, MCQs, vernacular pilots) on top of that sync layer; state handled with MobX. Rebuilt the content/CMS stack from EJS to Next.js APIs for test creation, multimedia upload, and teacher/PM reporting. Packaged reusable TypeScript/npm libraries used across FLN interactives, cutting duplicate work by ~30%; also shipped Mindspark vernacular learning modules in JS for government-school pilots.

Ramped onto SOL sync and API work: mapped legacy data flows, improved manual sync paths, and owned early backend delivery before promotion to Lead. Partnered on the offline React Native client (Realm + local storage) so field pilots could capture assessments without reliable network.

Mumbai, Maharashtra, India

Built Node.js REST APIs with MongoDB and Redis for Genie, Epsilon, and Assessment, improving response times by 60% for 10K+ weekly users. Owned Genie backend/API work for extracurricular classes: attendance, content, reporting, and integrations with live-class / whiteboard providers. Delivered reusable API + React/WebView modules so the same Genie flows ran on web and the mobile app. Improved Epsilon content-review workflows (multi-level review, comment resolution) with backend + UI changes used by school content teams. Added Assessment APIs and features for K-12 question-paper generation, including backup question sets.

About

Backend engineer with 4.5+ years building production APIs, microservices, and event-driven systems in Node.js and TypeScript. I work on API design, MongoDB/MSSQL, Kafka, GraphQL Federation, observability, and Kubernetes deployments. Recent work: hardening 15+ API flows on an enterprise insurance platform (parameterized SQL, JWT, structured logging) and deploying with kubectl from AWS EC2. At upGrad I owned high-throughput learner workflows: MongoDB bulkWrite (90% fewer DB round-trips), aggregation memory 145KB → 5KB (5x throughput), Kafka across 21+ services (~100K events/day), and a GraphQL Federation gateway that cut incidents by 60%. Open to backend/platform roles at product companies. Based in Bengaluru. Open to relocation. Node.js · TypeScript · NestJS · Kafka · MongoDB · MSSQL · GraphQL · Docker · Kubernetes
