Engineering with intent

I care about the layer most people never see — the APIs, pipelines, and infrastructure that make products fast, reliable, and observable.

Backend-focused full-stack developer with hands-on experience building scalable APIs, monitoring infrastructure, and real-time applications with FastAPI, Node.js, PostgreSQL, and WebSockets. Deeply curious about backend architecture, networking, and distributed systems.

Currently building backend services at Turuntai while finishing a B.E. in Computer Engineering — shipping real systems alongside coursework.

Based in

Biratnagar, Nepal

Working remotely with distributed teams, mostly async, always shipping.

Built to scale

Load balancing, consistent hashing, and services designed to stay fast under real traffic.

Observability first

Metrics, logs, and dashboards with Grafana, Prometheus, and Loki so nothing fails silently.

Selected Work

Things I've shipped

A handful of projects where design, engineering, and obsession met a real deadline.

AI Microservices2025

IntentFlow

A microservice-based AI system that turns natural language commands into executable backend actions — intent classification with sentence-transformers and cosine similarity, a Node.js API gateway, JWT auth, and a React frontend for secure end-to-end interaction.

NoticeWatch

A cross-platform Flutter app for real-time college notice updates backed by FastAPI — automated web scraping and scheduled pipelines with APScheduler keep notices synced end to end, from scraping and processing to storage and serving.

The Path

Where I'm headed

From classroom systems projects to shipping production backend services — learning fast and building in the open.

2026 — Present · Remote

Junior Full-Stack Developer

Turuntai

Designed and developed backend architecture, APIs, and services with FastAPI and PostgreSQL. Implemented monitoring and logging with Grafana, Prometheus, Loki, and Promtail, built admin dashboard features and backend integrations, and handled deployment, reverse-proxy configuration, and production issue resolution.

Let's build something
worth shipping

I'm open to backend and full-stack opportunities. If you're building something that needs solid systems underneath, I'd love to hear about it.
