Bachelor in Information Technology (BIT)

• Architected an event-driven API monitoring system using Kafka to detect and process failed service requests asynchronously
• Designed a fault-tolerant retry pipeline with exponential backoff and Dead Letter Queues to safely reprocess failed requests
• Implemented checksum validation to ensure integrity of retried API payloads
• Introduced Redis caching to reduce database load and improve API response latency
• Built modular backend services with Node.js and Express for scalable system design
• Developed microservices with asynchronous service communication
• Implemented API gateway routing and service isolation to improve maintainability
• Containerized services using Docker for consistent development and deployment
• Built responsive frontend applications using React, Redux Toolkit, and React Query

• Built responsive front-end features using React + TypeScript
• Created and optimized REST APIs using Hono + Bun and Node.js
• Improved performance by reducing backend resource usage
• Implemented Docker-based workflows for consistent deployment
• Debugging, testing & cross-browser fixes
• Worked in Agile environment (scrum, Git-based workflow)

• Split roles properly with JWT, pushed live availability over Socket.io, and put Redis in front of hot reads. The product became about booking reliability, not pretty cards.
• Live platform at kaamsewa.com with search, bookings, admin dashboard, and roughly 40% faster responses after caching.
• Utilized: Node.js, React, TypeScript, PostgreSQL, MongoDB, Redis, Socket.io, Docker

• Role-based onboarding, separate listing/order flows, search/filters that match how people actually browse, and caching on the chatty APIs.
• Live at nepalkisan.com: farmers manage listings independently; buyers discover and order without admin babysitting.
• Utilized: Node.js, React, TypeScript, PostgreSQL

• Turned it into a visual atlas: clear sections, concrete patterns, and a UI that treats diagrams as the primary language, not decoration around paragraphs.
• Live at systematlus.vercel.app: a visual backend engineering reference you can actually browse when designing or debugging systems.
• Utilized: Next.js, TypeScript, React, Tailwind CSS

• Focused the product on catalog → cart → order with clearer seller/customer separation and a storefront that feels local, not imported.
• Live at shopcartnepal.com: shopping cart and storefront for Nepal.
• Utilized: React, TypeScript, Node.js, MongoDB
