The short version

Frontend Engineer at Ultrahuman, ex-appmaker.xyz, ex-Lascade. I ship React, React Native and Next.js, optimize the parts no user will ever thank me for, and document it so the next person — me, in six months — doesn't cry.

Website & storefront2×+ fasterGrowth, shipped

I build Ultrahuman's website and storefront — driving growth one landing page at a time. Made the whole site more than twice as fast, with a backlog of further optimizations lined up and waiting their turn.

URL Shortener — No Fluff

Auth + dashboardTiny pathsLive in prod
stackNext.js / TypeScript / Postgres
statuslive in prod

A link shortener with accounts and a dashboard, minus the marketing-speak. Short domain, shorter paths, zero patience for bloat. 'kutti' means small in Malayalam — so does the feature set, on purpose.

Relationship-Clarity Engine

Describe a messy situation, get a structured read on it. Anonymous, no accounts, with a tone slider from 'Gentle' to 'Direct' — because not everyone wants the truth at full volume.

Whole-App-In-One-SVG Compiler

Inlines JS/CSS/assetsMulti-framework
stackTypeScript / Bun / SVG
reliability~60%

A zero-config bundler that base64-inlines an entire web app — JS, CSS, fonts, images — into a single standalone .svg. In theory. In practice it works about sixty percent of the time, which is either a bug or a personality.

Abandonware loose ends

  • WhatsDown2023repo

    WhatsApp, but mine. I looked at Meta and thought 'how hard can it be.' Reader: it is hard.

  • jeepeetee2023repo

    ChatGPT, but worse — on purpose. It talks back, it's frequently wrong, it is technically AI.

  • netflix-clone2022repo

    The Netflix clone every dev builds. No content (lawyers), but the rows scroll beautifully.

I also write, apparently

Open to interesting problems and the occasional impossible deadline. Bring a spec or a mess — I'll take both.
