Work experience

Full Stack Developer at Vivasvat Revolutions Limited, Mar 2024 - Present · 2 yrs 4 mos, Remote, • Served as Founding Engineer across multiple fintech MERN applications — owned the entire technical stack from architecture decisions through live release, establishing engineering standards, deployment pipelines, and system design patterns. • Owned end-to-end system design of a microservices backend using Node.js/Express/TypeScript — produced architecture docs that reduced new engineer onboarding time by ~50%. • Built a multi-tenant MongoDB setup with complete data isolation per client — reduced new tenant provisioning from 2–3 days to under 4 hours. • Set up micro-frontend architecture using Vite Module Federation — enabled independent deployment of app modules without a monolithic release cycle. • Built an LLM-powered customer support microservice using OpenAI API (GPT-4), deployed as a standalone Node.js service reused across 3 fintech products. • Built an in-house e-signature system for document signing and approval workflows — eliminated dependency on third-party services. • Improved API performance via MongoDB indexing and optimized aggregation queries — reduced response times by ~200ms. Added Redis caching, rate limiting, and session handling via AWS ElastiCache. • Handled auth using JWT + RBAC, and used AWS KMS for field-level encryption of sensitive financial data. • Managed full AWS infrastructure (EC2, S3, CloudFront, Lambda, API Gateway, Amplify, ElastiCache) — configured Nginx as reverse proxy handling SSL termination and routing across microservice endpoints. • Set up GitHub Actions CI/CD pipelines across dev, staging, and production environments. • Conducted AWS infrastructure cost audit — right-sized over-provisioned EC2 instances and resolved Lambda cold start issues, reducing monthly cloud spend by 15–20%. • Integrated Aadhaar and PAN verification via Singzy API to automate KYC checks — replaced a manual process that previously took 24–48 hours.

FULL STACK DEVELOPER at Vigorus Healthtech Private Limited (Chikitsa), Jan 2023 - Mar 2024 · 1 yr 3 mos, Jaipur, Here's the exact copy-paste text for Vigorus/Chikitsa experience: • Built a Node.js + Puppeteer PDF generation system for prescriptions and appointment summaries with automated WhatsApp delivery — processing 1,000+ documents/month with zero manual intervention. • Developed a QR-based appointment check-in system with real-time webcam scanning — improved on-site patient flow efficiency by ~30% and eliminated paper-based queues. • Integrated AI-powered APIs (AWS Rekognition + custom NLP pipeline) to analyse prescriptions and health reports — reduced doctor data-entry time by ~40%. • Implemented role-based access control (RBAC) in MongoDB across 5 user roles (doctor, nurse, receptionist, admin, patient) to enforce strict data security. • Configured and managed AWS infrastructure (EC2, S3, Lambda) for scalable delivery — set up automated daily backups and multi-AZ failover. • Built interactive canvas-based UI workflows using Fabric.js for IoT device data visualisation and annotation — integrated real-time sensor feeds into the clinical dashboard. • Optimized frontend performance via server-side rendering in Next.js — reduced page load times significantly.
