Senior Software Engineer · Remote, India

Hi, I'm Mansi. I've been working in software development for ~10 years, building full-stack applications for B2B enterprise products.

I've worked on systems handling large data volumes and critical business workflows, focusing on scalability, performance, reliability, and resolving production issues and customer-impacting incidents.

I enjoy solving engineering challenges, exploring new technologies, and taking ownership end to end.

  • React.js
  • Node.js
  • Express
  • TypeScript
  • PostgreSQL
  • MongoDB
  • Microfrontends
  • Microservices
  • Next.js
  • GraphQL & REST APIs
  • CSS Frameworks (Tailwind, Styled Components, Material UI)

Key work

Global supply-chain platform · Tech lead

One shared platform behind 8 production apps

I led the common-ui monorepo and owned all 8 supply-chain apps across multiple teams. Each app had built its own login screen, auth flow, navigation and user profile. I moved those into 4 shared, independently deployable packages, so a fix or a new feature now ships once instead of eight times.

  • Monorepo
  • React
  • TypeScript
  • Shared packages
  • Multi-team ownership

Campaign management · Full stack

Full-stack campaign platform for global fast-food brands

I built the frontend and backend of the Events app, which marketing teams use to plan and run campaigns for major fast-food chains. React and Redux Saga handle the UI and async workflows, on Node.js and TypeScript services backed by PostgreSQL.

  • React
  • Redux Saga
  • Node.js
  • TypeScript
  • PostgreSQL

Tax-compliance SaaS

Bringing order to server state across microfrontend dashboards

Dashboards across the microfrontends each tracked long-running jobs like tax calculations with their own fetch and polling code, which caused duplicate requests and stale data. I introduced TanStack Query to give them one shared cache, request deduplication and built-in polling until jobs finish.

  • Microfrontends
  • TanStack Query
  • React
  • Microservices

Healthcare access management

Legacy app rebuilt on React, ~20% faster UI load

I migrated a legacy access-management platform to a new React app built from scratch. The worst screens froze on long infinite-scroll lists, so I added list virtualization and moved to cursor-based pagination. Code splitting and memoization handled the initial load.

  • React
  • Virtualization
  • Cursor pagination
  • Code splitting
  • Legacy migration
