What I'm looking for

I’m open to remote work where I can build full-stack products with Next.js/Node.js, focusing on scalable APIs, secure auth, and payment reliability (Stripe/webhooks, idempotency). I want a team that values clean engineering and fast iteration.

I build full-stack web platforms end-to-end with Next.js and Node.js, using TypeScript and PostgreSQL to ship dependable features. In OpScale, I created a wholesale credit ledger that tracks deferred/partial payments with running balances and payment history—plus QR payment verification and automated recovery workflows.

On my Multi-Role Merchant System, I modeled products, carts, and orders in PostgreSQL, implemented RBAC (merchant/admin/customer) with JWT auth, and integrated ImageKit for image delivery. I also built an AI Text Summarization Platform with OpenAI/Gemini ingestion and retry logic, and I engineered Stripe subscription tiers with idempotent webhook processing, usage-gated access, and rate limiting—deploying through Vercel with clean, env-based configuration.

Experience

Work history, roles, and key accomplishments

Multi-Role Merchant System

Designed a relational PostgreSQL schema for products, carts, and orders with indexed queries, then implemented RBAC (merchant/admin/customer) using JWT auth. Integrated ImageKit for product image CDN and built idempotent Stripe webhook processing with structured API error handling.

Credit Ledger (Khata)

OpScale

Built a credit ledger (khata) for wholesale dealers to track deferred/partial payments, running balances, and per-buyer payment history. Modeled the dealer→buyer→invoice→payment schema in PostgreSQL and implemented QR payment verification with automated recovery workflows.

AI Text Summarization Platform

Built APIs for text/PDF ingestion and AI summary generation using OpenAI and Gemini, with retry logic and rate-aware error handling. Implemented Stripe subscription tiers ($9/$19) with usage-gated access, per-user quota enforcement, and rate limiting.
