Apps I'm actively engineering. Each one leads with the stack and the hard problem
it solves, plus an honest note on current scope.
Ar
Artha — Sense Maker
In development · used daily
An on-device multimodal AI app: ingest audio, video, images, text, PDFs and docs, then summarize, translate and chat with the content. The whole inference pipeline runs on the device — no cloud, no data collection — built around a pluggable engine layer so each modality sits behind a clean domain port. Artha (అర్థ) = “meaning.”
- On-device Gemma LLM engine driving summarize and chat
- ML Kit OCR plus on-device translation; STT/TTS speech pipelines
- Engine-port architecture — each modality swappable behind an interface
- Clean Architecture · MVVM · Koin DI · sealed-state Compose UI

Development status
- Engine layer live; remaining modality flows being wired in
- On-device inference is compute-heavy — large media processes slower on low-RAM devices
- Development build, installed outside Google Play

ER
Erosion Rider
In development · playable
An original 2D game on a custom momentum-physics engine, with a mechanic I designed: the terrain permanently erodes along the path you ride, and that wear persists across runs. I built it by reverse-analysing the terrain and momentum models behind proven rider titles, then inventing the erosion layer on top.
- Custom momentum physics plus procedural keypoint terrain generation
- Persistent erosion — carves are serialized and survive across sessions
- 37 real worlds from Earth's core to the edge of the universe, 16 riders, 132 achievements
- Crates with Magnet / Boost / Shield power-up cards that level up to 5, plus coins and a 7-day daily-reward streak
- Full art pass: every screen, world, rider and pickup generated with FLUX and hand-reviewed

Cascade Reaction
In development · playable
A turn-based chain-reaction strategy game on a custom cascade engine — place orbs, trigger chain detonations that capture opponents' cells, last player standing wins. Underneath it is a deterministic wave-propagation simulation with layered tactical rules on top.
- Custom cascade engine — deterministic chain-detonation wave simulation
- Fog of War: per-turn visibility recomputed from owned and adjacent cells
- Magnetic Shield cards that absorb a cascade wave; radioactive hazard cells
- Animated detonation waves rendered in Compose; clean state management

SP
SimplePlayer — P2P Streaming Engine
Systems engineering demo
A BitTorrent stream-while-downloading engine: paste a magnet link and playback starts after a few seconds of prebuffering, with no wait for the full file. The hard part is the piece-aware stream that blocks an ExoPlayer read precisely until libtorrent has written the required bytes to disk, with sequential download and head/tail piece prioritisation feeding a local HTTP range server.
- libtorrent4j with sequential download and head/tail piece prioritisation
- Custom local HTTP range server streams bytes to ExoPlayer as pieces land
- Piece-aware InputStream blocks a read until its data is written — seek-capable
- Foreground service with correct Android 14+ FGS types keeps the download alive

Scope and status
- An engine demo — the UI is intentionally minimal, the streaming pipeline is the deliverable
- Far-ahead seeks wait on piece download; magnet input is sanitised before parsing
- Development build, installed outside Google Play
Note: BitTorrent is a content-neutral protocol — use only with content you have the rights to (public-domain media, Linux ISOs, openly licensed files).

Installing these builds: they are distributed as APKs outside Google
Play, so Android will ask you to allow installs from your browser or file manager. These are
active development builds shared for a hands-on look at the work — features and data may change
between versions. None of them collect personal data, and Artha's AI runs entirely on-device.
