Vishesh Kumar Dubey · Fullstack Product Engineer

I build products end to end, and the stuff underneath that keeps them fast.

Four years in fintech, ed-tech, and enterprise retail. These days I'm replatforming the frontend of a live US lending product at LendAPI. One module at a time, without taking the business offline.

LendAPI · 2025 to present

Django → React

full replatform, product stayed live

Replatforming a live lending product

The problem

Django templates. Slow to ship, hard to hire for.

My part

Wrote the migration plan and led the move to React, TypeScript, and Vite. One module at a time, product stayed live.

The calls made

Shared Radix/Tailwind components, TanStack Query for data, lazy routes to cut bundle size.

Outcome

Auth, documents, notifications, and reporting on the new stack.

7,000+

students, one sitting · India Book of Records

India's largest online Gita exam

The problem

Thousands of students registering, paying, and sitting a timed exam in one go.

My part

Owned the SvelteKit frontend: checkout, referral, CMS, LMS, and admin dashboards.

The calls made

SSR and SEO (+40% organic traffic). Reusable components for exam-day fixes without breaking checkout.

Outcome

7,000+ students, India Book of Records. Conversion up 30%.

1M+

daily users, two years in production

File infrastructure at retail scale

The problem

File transfers across systems serving 1M+ daily users.

My part

Built the SFTP/FTP file manager (React + Azure Functions). On-call for the integration platform.

The calls made

Event-driven Azure services. Caching and batching where throughput mattered.

Outcome

Two years at 1M+ daily users. Stable file ops.
