Mobile & frontend engineer.
At Reelax, a creator-brand marketplace, I'm the main engineer on its React Native creator app, lead the frontend of its new Next.js brands app, and have shipped across six production apps. I also built the backend for Twik, a voice keyboard that passed half a million accounts in ten weeks, and work across its Android, iOS and macOS apps.
- Status: Open to mobile and frontend roles. At Reelax since July 2025.
- Work: Remote preferred, or relocating to South India. Nagaon, Assam (IST).

Reelax, six production apps · 2025 to now
Led the creator app's move from React Native 0.70 to 0.82 with RevoPush OTA updates and Sentry crash reporting. Built the first version of the Next.js marketing site, which launched about 70,000 pages in about a week. On Spotlyt, an AI influencer-marketing product, I'm the top committer on the web app and its delivery tool.

Reelax for brands · 2025 to 2026
A data-heavy web app where brands find creators, run campaigns and pay for them. I was its top committer from December 2025 and now lead the frontend of its Next.js rewrite, Brands V2.

Twik, a keyboard you talk to · 2026 to now
I built the Fastify backend, moved dictation and sign-in in the Android and iOS apps onto it, added subscription sync, and I'm the top contributor to the macOS app. 534,444 accounts from the August public launch to 5 November 2026, 125,110 of them on the biggest day.

A native macOS client where folder rules choose the GitHub account, and each git command gets its token and identity through per-command flags, so ~/.gitconfig is never touched. Built solo in three days with AI coding assistance.
