01 / ABOUT

Second-year CSE (AI & ML) at SRM IST. I build production systems end-to-end — backend, frontend, infra, release pipeline — alone.

Native Windows overlays in Rust/Tauri. HRMS platforms on Flutter with biometric attendance. Registration systems holding 1,800+ live users. Three internships, one freelance venture (Ascendry, Udyam-registered), and a habit tracker selling on Gumroad. The pattern is the same every time: pick the hard part, ship it, keep it running.

04 / PROCESS

The same four moves, every time.

  1. 01

    Pick the hard part

    The interesting problem is usually the one nobody wants to own — biometrics over TCP, a native Windows overlay, rate limiting under real load. Start there, not at the scaffolding.

  2. 02

    Build it end to end

    Backend, frontend, infra, release pipeline. One person holding every layer means no handoffs, no waiting, and no part of the system nobody understands.

  3. 03

    Ship it

    Tagged releases, real installers, real users. A branch that never merges is not work — it is a hobby with extra steps.

  4. 04

    Keep it running

    Shipping starts the maintenance, it does not end the project. Eight products still up is the number that actually matters.

05 / REACH ME

Open to work that ships.

Internships, freelance builds, or anything that needs one person to own it end to end. Chennai-based, remote-friendly. Pick whichever channel fits — they all reach me.
