Mahak Bansal

I’m a Full Stack Engineer with 4+ years of experience building scalable, production-grade web applications. I specialize in React.js, Next.js, Node.js, TypeScript, and AWS Serverless architecture, with a strong focus on shipping systems that perform under real-world load.

In my current role, I engineered a production React.js CRM admin dashboard from scratch, including role-based access control for 4+ user types, dynamic lead pipeline views, and real-time status updates. I reduced agent task-switching by 40% and cut UI development time by 35% by building a reusable component library and enforcing a consistent design system.

I’ve also focused heavily on performance and reliability: I optimized React rendering to achieve sub-2 second initial load on the CRM dashboard, and I implemented server state management with Redux Toolkit RTK Query and TanStack Query. For lead operations, I automated 100% of ad-generated lead capture from Facebook and Google Ads, reducing data lag to under 5 seconds with zero manual CRM entry.

My work extends across real-time and integrations—integrating WhatsApp Business API for automated follow-up drip sequences (improving sales response time by 70%), architecting a unified payment gateway layer with webhook-driven reconciliation (achieving zero downtime post-launch), and building live-streaming infrastructure using Agora SDK for sub-second latency. I’m comfortable working across microservices, Redis Pub/Sub event architecture, BullMQ/worker processing, and CI/CD/Agile workflows to deliver measurable business impact.
