I build games, mobile apps and web products, and I like working with technology while it is still new.

Full-stack developer. I publish my own apps and games as rkj dev.

Now: CandleDeep, my first game for Android, is in testing on Google Play.

  1. Android game

    CandleDeep

    Independent release under rkj dev. Design, code and publishing.

    A pixel-art survivor roguelite. You wake at the gate of the Hollow with one candle of time: hold off the horde until it burns out, carry your gold back up, and go deeper. Played one-handed in portrait.

    2 stages, 20 enemies, 8 weapons, 7 heroes

    Godot 4 and GDScript, Google Play Billing, AdMob with consent messages for EU and US privacy rules.

    CandleDeep: a knight holding a candle in a dark dungeon, with the words Survive until the candle burns out.

  2. Web platform

    AvsarIQ No longer maintained

    Designed and built end to end.

    A calmer way to follow Indian government job openings. It brings official notifications, eligibility, deadlines and application links into one place, lets people compare their profile with each post's requirements, and keeps the official source beside every detail.

    Next.js, React, TypeScript, Supabase and PostgreSQL on Vercel. Accounts and onboarding, saved and applied tracking, SEO and performance work.

  3. Android app

    PranArog

    Designed and built. Coming soon to Google Play.

    A calm medication tracker. Precise reminders built on Android's exact alarms that don't drain the battery, Gemini-powered summaries of your schedule, dietary notes and possible interaction flags, and one tap to wipe your data and leave.

    Android, Firebase and Cloud Firestore, Gemini API.

  4. Android app

    SocialG

    Application developer, January 2025 to June 2026.

    A cloud gaming app: people play popular games without downloading them and earn rewards for playing, competing and inviting friends. Alongside building the app, I took on startup leadership and team management.

    100K+ downloads on Google Play

  5. Website

    Shrutim

    Built with Shivam.

    A home for mantras and stotrams, with their lyrics, meaning and proper translations, made for devotees reading on their phones.

    500K+ organic search impressions

    Next.js, React, Firebase, MongoDB and AWS, with search engine optimisation at the centre.

  6. Android app

    Magic

    Co-founder. Product, Android development and the team.

    The cloud gaming and rewards platform that later became SocialG. Games streamed from the cloud, so nothing to download, with prizes and gift cards for playing, completing missions and inviting friends.

    350K+ users

About

I'm a full-stack developer with a deep interest in emerging technology. I've co-founded a startup, shipped Android apps used by hundreds of thousands of people, built web platforms that rank on search, and now make apps and games of my own.

I like owning the whole path of a product: the idea, the interface, the code, the store listing, and what happens after launch.

  • B.Tech in Computer Science (Internet of Things), Pranveer Singh Institute of Technology
  • First prize, Ideathon Innovation Blitz
  • HackerRank certificate
Games
Godot, Android releases, in-app purchases and ads that respect players' privacy choices.
Mobile apps
Android development, Google Play launches and app store optimisation.
Web apps
Next.js, React, TypeScript, Supabase, Firebase, PostgreSQL and MongoDB, deployed on Vercel, AWS and Google Cloud.
Emerging tech
AI-assisted products, IoT with Arduino, Raspberry Pi, sensors and MQTT, and early work with blockchain.
