Things I've built
Live and playable, not screenshots. Have a go.
Git City
Turns any GitHub repo into a living 3D city
Paste a public repo and watch it rise as a low-poly 3D city: files become buildings, commits drive growth, deleted files become ruins. An intuitive way to feel a codebase's scale and history.
the hard part
Mapping arbitrary repo structures to stable, readable urban layouts and rendering them smoothly in the browser with real-time generation.
DevLens
A sharper network inspector for the browser
A Chrome DevTools extension for developers who debug API-heavy apps: side-by-side response comparison, structural JSON diff, automatic TypeScript interface generation from responses, and a cascade timeline.
the hard part
Working within the Chrome DevTools Protocol and Manifest V3 constraints while generating accurate TypeScript types from arbitrary JSON shapes.
tan(AI)
Non-linear, branching AI conversations
Reimagines AI chat as a canvas: explore tangents as visual branches without polluting the main thread. Each branch keeps its own history but references only relevant parent context, so token usage stays lean.
the hard part
Designing the branching context model, so each node inherits just enough parent context to stay coherent while keeping prompts small and fast.

About
I'm a senior full-stack engineer who's spent 5+ years shipping production web apps, owning features end to end, from the interface down to the APIs and infrastructure behind them.
I've been fully remote and async-first since day one, so I'm comfortable driving work across timezones without hand-holding. Whether I'm building a product for a team or a developer tool for fun, I care about the same things: speed, clarity, and the small details that make software feel good to use.
Right now I'm looking for high-impact remote roles, and I'm open to relocating internationally for the right team.

When I'm not shipping
The short version of the human behind the code.
Solo travel
Mostly solo. I go where I want, at my own pace, and I'm comfortable being dropped somewhere new, which is half the reason relocating doesn't scare me.
Countries
India
NepalIndian states
Bike rides
Recently got into long rides. Still the best way I've found to switch off, clear my head, and just follow the road for a while.
Anime & movies
Anime and films are how I switch off after a build. My desk wall has quietly become a shrine: One Piece, a katana, Fight Club, and most of Christopher Nolan's filmography.
