System Architect, Kathmandu

Engineer by mind, poetry in heart

I help startups bring a product to life, and help the teams who already have one keep it standing.

Major support areas

Three places I make the difference

Most of my work sits in one of these, and often in all three at once when a product is finding its feet.

01

Development

Product engineering, front to back.

Web and mobile products taken from an empty repository to something people pay for. Frontend, backend and infrastructure held in one hand, so the seams stay few and the handovers stay short.

  • Web and mobile products
  • APIs and integrations
  • Cloud infrastructure
02

Data Engineering

Pipelines that keep their shape as they grow.

Collection, storage, search and streaming, sized to what the business actually reads and writes rather than to what looks impressive on a diagram.

  • Pipelines and warehousing
  • Search and analytics
  • Migration and cost tuning
03

AI Automation and Assistants

Models put to work, not put on display.

Retrieval, agents and assistants built into the product itself, chosen for cost and business impact rather than for default complexity, and taken all the way to production.

  • Assistants and agents
  • Retrieval over your own data
  • Workflow automation

Time under load

Twelve years of building the thing that has to stay up

More than twelve years across system architecture and computer engineering, most of it spent on platforms where downtime is expensive and the bill arrives whether or not anyone is watching it.

That has meant distributed platforms running across dozens of cloud services, rebuilds that cut running costs several times over, mobile products past a million downloads, and AI models taken from a research paper into daily use. It has also meant leading teams, which is the part that decides whether any of the rest survives contact with a deadline.

  • 40+ Cloud services in production architectures
  • 1M+ Combined mobile downloads shipped
  • 5x Running cost reduced by architecture alone

Public activities

Speaking, moderating, and the occasional panel

Keynotes and panels on artificial intelligence, engineering practice and technology careers. Each one links to the recording, the organiser's own announcement, or both, so you can check it happened.

Subas Chandra Baral, President of the Nepal Engineers’ Association. A festival session that sat where the engineering and the writing meet.

  3. Poster for the Madan Bhandari Memorial College job fair and career counselling session

    Speaker

    A guide to national and international technology careers for IT students

    Held by
    Madan Bhandari Memorial College, Placement and Internship Committee
    Where
    MBMC Hall 305, Kathmandu
    When
    9 Ashadh 2083 (June 2026)

    A session for IT students at the college Job Fair and Career Counselling, held during its silver jubilee year, on how technology careers are actually built, at home and abroad, and what students can do before they graduate to make the international route a real option.

Outside the code

I write out of the code sometimes, and those ones come from the heart.

Verse and the occasional argument, written in Nepali and kept in one place since the beginning.
