Bharat Ravalot

Economics and Data Science at UC Berkeley. I build products, studios and the occasional world.

A first-year at Berkeley studying Economics and Data Science, drawn to product management and startups. Most of what I make starts as something I care about. I love mechanical keyboards, so I made Thock. I thrift, so I made pileGo. My family speaks Marwari, so I spent two years helping preserve it.

Keeping Marwari

Linguistics Research Assistant, University of Texas at AustinOct 2025 to Jan 2026

Marwari is the language of my family and of the Thar. I have spent two years helping keep it written down and spoken.

Built a cleaned speech dataset from 5+ hours of endangered Marwari audio: ran it through OpenAI Whisper, hand-corrected the transcripts, and compared results against existing Kangri speech models.
Co-wrote a $20,000 Seksharia grant proposal to fund Marwari language-preservation work.
QA-tested an online Marwari course used by 50+ learners before release.
Volunteer Historian at the Marwari Restoration Initiative (Jun 2023 to Jan 2026): built a 300-term digital dictionary.

Things I have built

Thock

Designer and engineer2026

A parts picker for custom mechanical keyboards: answer eight questions and get complete builds made from real store parts.

Custom keyboards spread cases, PCBs, plates, switches and keycaps across dozens of retailers. Thock turns how you want a board to feel and sound into ranked builds, then lets you swap any part while it checks compatibility.

It is a static site with no backend. A daily pipeline crawls public store feeds, rejects incomplete crawls, and ships a small boot snapshot ranked by the same code the browser uses, so the first screen is instant.

8,195 build-ready parts from 24 stores, refreshed every day.
Checks switch family, PCB and plate fit, keycap layout, stabilizers and hot-swap against solder.
Builds are shared as versioned URLs that encode every part and answer, with no server storage.
Refreshes are blocked if a required source fails or the catalog shrinks by more than 20%.

The pile: unsold pieces scattered on a paper floor with kraft price tags

pileGo!

Designer and engineer2026

A free, open-source closet for people who resell clothes: photograph a piece, let the AI write the listing, and send it to six marketplaces at once.

Reselling means retyping the same jacket into eBay, Vinted, Depop, Poshmark, Mercari and Grailed, then remembering to take it down everywhere when it sells. pileGo keeps one record per piece and does the rest.

Only eBay has a public seller API, so pileGo is honest about reach: every marketplace is labelled Automatic, One click, Auto-post, Assisted or Listing kit, and a browser extension does the work in the seller's own logged-in tab.

AI scan of up to 12 photos reads brand, size, colours, materials, condition and flaws, writes the description and suggests a price.
Cross-lists to eBay, Vinted, Depop, Poshmark, Mercari and Grailed, each within that site's limits.
When a piece sells anywhere, removal from every other marketplace is queued.
Pricing blends the AI estimate, comparable eBay listings and your own past sales, and says why.
Runs on free tiers: Supabase, Google Gemini and Cloudflare Pages. AGPL-3.0.

Strata

Designer and engineer2026

A research instrument for population genetics: place a genome among ancient and present-day populations, then test which ancestry models the data supports.

Strata reads raw DNA from the big consumer services, places it in a curated library of reference populations from the Allen Ancient DNA Resource, and fits mixture models with bootstrap uncertainty.

Formal tests (qpAdm, qpWave, f4) run through ADMIXTOOLS 2 in a containerised R worker. An AI research agent can plan and critique analyses, and a grounding check flags any number it states that no tool returned. The agent never sees genotypes.

Keeps exploratory fits and formal tests apart everywhere: in result types, reports, the UI and the agent's tools.
Research agent with 13 tools over the real engine, retrieval over a methods corpus, and a deterministic grounding check.
Raw DNA is stored only as encrypted panel dosages and is never sent to a language model.
Reproducible reports record input hashes, parameters, software and reference-data versions.

+1 Speed Sponge Escape

Creator, free-to-play Roblox gameAug 2026 to present

A speed simulator and obstacle course for PC and mobile that I designed, coded in Luau and launched.

Peaked at 200+ concurrent players.
Raised tutorial completion from 54% to 70% by tracking where new players quit, then simplifying that step after mobile playtests.
Lifted day-1 retention from 0.28% to 2%+ and average session length from 8 to 22 minutes by rebalancing rewards and progression on player feedback and two-week cohort data.

Rally Assist

Extension authorOct 2026

A browser extension for Rally, Aiden Guan's phone-as-paddle table-tennis game, that retimes swings to the exact contact instant.

Rally turns a phone into a table-tennis paddle. I did not make Rally; I made Rally Assist, a Manifest V3 extension that reads the game's own simulation instead of guessing from pixels.

It hooks the game's update loop for timing, adds shot presets and placement, and restores every original method the moment it is switched off.

Perfect timing, auto-return, auto-serve, five shot presets and four placement modes.
Uses the game's simulation clock and predicted contact, not a UI poll.
Reversible hooks: disabling restores only the wrappers this instance still owns.
No dependencies, no background worker and no network requests of its own.
