Senior Full Stack Engineer

Faridabad, Haryana
Jan. 2023 – Present

Architected end-to-end multi-tenant SaaS engines leveraging NestJS and PostgreSQL with isolated schema partitioning, dynamic RBAC authorization, and automated tenant onboarding.

Built scalable, modular backend microservices and APIs using Node.js, NestJS, Fastify, GraphQL, and Drizzle ORM, managing complex transactions and connection pooling.

Engineered asynchronous processing queues with BullMQ and Redis to offload CPU-bound background jobs, including PDF generation, automated report scoring, and bulk notification dispatching.

Integrated multimodal LLM workflows (OpenAI, Gemini, Claude) into core application pipelines, executing automated document extraction, contract analysis, and fallback retry handling.

Designed high-concurrency real-time admin portals and dashboards featuring server-side pagination, structured error handling, dynamic filters, and optimistic updates.

Implemented security hardening across all production endpoints, incorporating request payload sanitization, structured logging, JWT token rotation, and rate limiting.
