Backend-focused full-stack developer

I build systems behind real business workflows: commerce, payments, shipping, warehouse operations, notifications, data migrations, and deployments, with end-to-end ownership.

Experience

Full-Stack Developer

C S Tech Infosolutions Pvt. Ltd., Bengaluru

Sept 2024 – May 2026

  • Built and owned 4 live apps: server setup, end-to-end development, architecture decisions, outage resolution, data corrections and deployments.
  • Integrated Razorpay and PayTM for order payments, Zoop for user onboarding and Shiprocket for shipment delivery.
  • Split the Dealsdray monolith into microservices, modernized the legacy Prexo codebase and designed and built Notification Console for the growing user base.

Work

Dealsdray

E-commerce platform. Took it from unfinished to production, migrated 70K+ legacy users and orders, and integrated Razorpay, PayTM, Zoop and Shiprocket.

Result: 30K+ daily users and 2K+ monthly orders.

Prexo

Warehouse processing system. Modernized the legacy codebase and built a utility that re-lists unsellable units as fresh imports, so stock that was stuck could be sold again.

Result: Inventory recovery up 30%.

Notification Console

A push notification service any app can connect to. Write a notification once and it is delivered to every user’s phone, with delivery results tracked. Designed and built end to end.

Result: Campaign runs cut from 15 minutes to under a minute.

Rekrafted

E-commerce site. Built product grading and categorization with grade-specific listings and pricing.

Result: Grading covers 70% of inventory; orders up 15%.
