## Site map

- [Home](https://cv-siddharth.vercel.app/): the headline numbers, the case studies, experience, skills, writing, a 3D storyboard of how it all connects, and contact.

### Proof: the numbers, and what verifies them

- [The Lab Bench](https://cv-siddharth.vercel.app/lab): Ten experiments that prove the numbers, running in your browser: Dice.tech production metrics, five personal builds and seven years of chess.
- [The 3D Storyboard](https://cv-siddharth.vercel.app/map): The projects and the ideas that connect them, as a constellation you can orbit. Every edge is a real dependency.
- [The Ops Board](https://cv-siddharth.vercel.app/ops): A control loop rendered as a page: every workflow, every generated dataset against its own SLA, the shipped fleet, and a ledger of the failures a green check did not catch.
- [Hire](https://cv-siddharth.vercel.app/hire): Senior Android engineer, platform owner of a ~964k-LOC app serving 50,000+ monthly users. GPS accuracy 50%→95%, crashes down 80%. Résumé, numbers, contact.
- [Résumé](https://cv-siddharth.vercel.app/resume): The résumé as a page, not a download. No chrome, no nav, printed to PDF straight from the browser. The artifact that actually leaves this site.
- [The Shelf](https://cv-siddharth.vercel.app/shipped): Every Android app that reached the Play Store from this work: three at Dice and Jugnoo, the rest white-label clients of the same platform, each one verified against its live listing.
- [The Making](https://cv-siddharth.vercel.app/making): The craft record for The Morkinstar Journals: the cross-lab ownership audits, what they killed, two portrait passes, and what the whole thing cost.

### Things that run: real programs, in the page

- [Compose Playground](https://cv-siddharth.vercel.app/compose): Write Jetpack Compose, watch it recompose live in a phone frame: reactive state, animation, and an AI that writes it for you.
- [The Blueprint Room](https://cv-siddharth.vercel.app/blueprint): The whole portfolio as an infinite canvas: a real-time 3D fly-through, an ASCII render of the same scene, and a sketchable whiteboard.
- [The Particle Forge](https://cv-siddharth.vercel.app/forge): A few thousand particles, each spring-tied to a letter, parting around your cursor and snapping back. Physics on a canvas.
- [The Terminal](https://cv-siddharth.vercel.app/terminal): A faux shell you can actually type in: ls the site, cat a project, or hit the backtick key from anywhere.
- [The Pulse](https://cv-siddharth.vercel.app/pulse): A live count of what visitors actually touch across this portfolio: which rooms get opened, what gets played with, and what nobody has found yet.
- [The Playground](https://cv-siddharth.vercel.app/playground): Every room as a building on one street, drivable in 3D. North is 2017, south is now, and a West District turns employers and case studies into towers.

### Corpus: long records, read as evidence

- [The Board](https://cv-siddharth.vercel.app/chess): Seven years of games across lichess and chess.com, mined: the rating arc in 3D, where games end, a shifting repertoire, and a bot trained on the openings you are looking at.
- [Weeb Central](https://cv-siddharth.vercel.app/weeb): Years of anime and manga kept by hand, read as evidence: a status column with no word for quitting, a score scale whose bottom half is unused, and the seasons that aired while the list wasn't looking.
- [Four Lanes](https://cv-siddharth.vercel.app/lanes): Work delivered, open source merged, writing published, chess played, month by month since 2019, on one shared axis. The same strip this profile's README draws, live.
- [The Time Machine](https://cv-siddharth.vercel.app/time-machine): This repo's own commit history, month by month since it started: how much changed, and when. A navigable record, not a live git shell-out.

### Writing: before the code, and alongside it

- [The Ink](https://cv-siddharth.vercel.app/ink): The writing years: three editions of MANIT's institute magazine, a literary society, four published stories, and everything written before the code.
- [Excelsior](https://cv-siddharth.vercel.app/excelsior): Three editions of MANIT Bhopal's institute magazine, readable here in full. English Editor on 2019 and 2020, Joint Chief Editor on 2021.
- [The Loopdown](https://cv-siddharth.vercel.app/loopdown): Field notes from building production Android: what broke, what the fix actually was, and the numbers on either side of it.
- [The Morkinstar Journals](https://cv-siddharth.vercel.app/anthology): A galactic field reporter files forty-eight short stories on fourteen gods and fourteen monsters, until he stops filing, burns the case, and walks into a city built to the dimensions of his own paperwork.
- [The Canon](https://cv-siddharth.vercel.app/canon): The rules the Morkinstar Journals are written against: seven laws, the count, the fourteen, and what the rendering can and cannot do.

## Projects, each with its own page

- [Gaddi](https://cv-siddharth.vercel.app/project/gaddi) (14 modules · 4 platforms · 10 bot personas): Deterministic Kotlin Multiplatform social-deduction game with ISMCTS bot AI, shipped across Android, iOS, Desktop, and Web.
- [Doori](https://cv-siddharth.vercel.app/project/doori) (49 modules · 5 platforms · 159 tests): Offline-first mileage, travel, and expense tracker spanning five platforms from one Kotlin codebase, with a real Kotlin/Ktor backend built in, off by default.
- [PaymentsLab-KMP](https://cv-siddharth.vercel.app/project/paymentslab-kmp) (44 modules · 66 gateways · 5 rails): A Kotlin Multiplatform systems showcase: real payment flows across dozens of providers, all behind a single PaymentGateway abstraction, backed by a Ktor server that owns order creation, signature verification and webhook reconciliation.
- [Candidai](https://cv-siddharth.vercel.app/project/candidai) (Active · 24 PRs merged to public career-ops · member of the career-ops-hq org): A local-first job-search engine rebuilt from scratch in Kotlin Multiplatform: resume onboarding, reverse-ATS discovery, evidence-based fit scoring and tailored résumés. Its scoring engine is ported and verified against the open-source career-ops project I actively contribute to upstream.
- [Portfolio Twin](https://cv-siddharth.vercel.app/project/portfolio) (Live · React on Vercel, CMP across 4 targets): An interactive résumé built twice, on purpose. The React 19 original runs on Vercel Edge with a provider-agnostic LLM assistant grounded in this same profile data. The Compose Multiplatform port renders the same portfolio from 63.1k lines of Kotlin to Kotlin/Wasm, Desktop, Android and iOS. An honest test of how far CMP reaches on the web, including where it doesn't.
- [STUTTER](https://cv-siddharth.vercel.app/project/stutter) (In development · private repo, public case study): Godot 4.7 in GDScript. A deterministic echo-replay spine powers cooperative echoes, ghosts, and boss desync from one system, with recorded input intent replayed through the same physics step. Built solo as an AI-orchestrated dev crew.
- [SINC-P](https://cv-siddharth.vercel.app/project/sinc-p) (Active · AGPL-3.0 · UGC 2023-compliant): Next.js 16 over Postgres with row-level security, rewriting a 2019 MANIT Bhopal final-year project (a downloaded complaint-box template, categories still reading E-commerce and Online Shopping) into a real compliance system: a statutory SLA clock, a hash-chained append-only audit trail, and published closure-time transparency with no login required.
- [The KMP toolkit family](https://cv-siddharth.vercel.app/project/kmp-family) (Active · MIT · vendored across 5 repos): The reusable libraries, the shared build logic and the app shape each live in their own repo, vendored into five consumers via Gradle includeBuild, so a version bump happens once instead of per project.
- [The Loopdown](https://cv-siddharth.vercel.app/project/the-loopdown) (Active · public): A dev-content engine and writing archive. A lesson pulled from a real project is written once and adapted to LinkedIn, dev.to, Hashnode and Medium, each with a generated branded graphic, plus the consolidated back catalogue.
