Selected work

Systems, products, and developer tools

A focused set of projects that shows how I approach product problems, backend architecture, AI workflows, and developer experience.

Cognora multilingual AI tutor

Flagship project · Individual build

Cognora

A multilingual AI tutor for LMS platforms.

Cognora helps students learn course content in English, Hindi, or Nepali, then generates quizzes, evaluates answers, and sends performance reports by email.

Architecture

Next.js frontend, FastAPI backend, dedicated worker, and Redis-backed queue, containerized with Docker and deployed on AWS EC2.

Key decision

Long-running ingestion, quiz generation, and reporting run asynchronously in the worker so request handling stays separate from AI workloads.

Verified functionality

  • Multilingual tutoring
  • On-demand quiz generation
  • Automated evaluation
  • Email performance reports
  • Next.js
  • FastAPI
  • Redis
  • Docker
  • AWS EC2
  • CI/CD
  • LangChain

OpScale wholesale operations platform

Product integration · Individual contribution

OpScale

AI-powered wholesale operations and credit ledger.

A single product for retailer balances, deferred and partial payments, outstanding dues, and natural-language business intelligence.

Agent: LangGraph connects five verified tools: overdue customers, top-selling products, revenue summaries, default-risk customers, and payment-reminder drafting.

Transport: FastAPI streams agent responses to the Next.js dashboard with Server-Sent Events (SSE).

PayBridge payment SDK documentation

Open-source developer tool · Individual build

PayBridge

A framework-agnostic TypeScript SDK for Khalti payments.

PayBridge gives Node.js, Express, and Next.js developers a typed initiate/verify workflow instead of reimplementing gateway integration details.

API design: a small surface built around initiate() and verify().

Packaging: a pnpm/Turborepo monorepo with documentation and integration examples.
