Hi, I’m Arjun L — currently open to SDE-1 roles

I build backends and AI systems, and run engineering at Lyptron.

I'm the only developer at Lyptron, the product studio I co-founded — I take client products from the first call to production: data model, APIs, apps and delivery. My work is used daily by contractors, music students and a law firm.

Where I work now

Lyptron

Co-founder & Lead Developer · April 2026 — present

A product studio delivering websites, SaaS, mobile apps and AI automation for clients.

lyptron.com

There's no engineering team behind me. I sit in the client call, write the scope, design the database and APIs, build the app, deploy it, and pick up the phone when something breaks.

What I own

  1. 01Scoping

    Turn a client problem into a written scope, estimate and milestones.

  2. 02Architecture

    Data model, auth, roles, payments and API design.

  3. 03Build

    Web, mobile (Flutter) and desktop (Electron) apps.

  4. 04Delivery

    Deploy, hand over, and support in production.

Shipped for clients

Selected work

Four products where I owned meaningful parts of the system, from repository to delivery.
