Apps

An on-device multimodal AI app: ingest audio, video, images, text, PDFs and docs, then Summarize · Translate · Chat with the content. The entire inference pipeline runs on the device — no cloud, no data collection — architected around a pluggable engine layer so each modality (LLM, OCR, translation, speech) sits behind a clean domain port. Artha (అర్థ) = "meaning."

• On-device Gemma LLM engine driving summarize & chat
• ML Kit OCR + 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

An original 2D game built on a custom momentum-physics engine, with a novel mechanic I designed: the terrain permanently erodes along the path you ride, and that wear persists across runs. I engineered it by reverse-analysing the terrain and momentum models behind proven surfer/rider titles, then inventing the erosion layer on top — plus a full retention loop.

• Custom momentum physics + procedural keypoint terrain generation
• Persistent erosion system — carves are serialized and survive across sessions
• Full game economy: coins, 7-day daily-reward streak, rarity-weighted gacha crates
• Designed from a systematic teardown of reference engines, not a clone

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. The engineering underneath is a deterministic wave-propagation simulation with layered tactical rule systems built on top.

• Custom cascade engine — deterministic chain-detonation wave simulation
• Fog of War: per-turn visibility recomputed from owned + adjacent cells
• Magnetic Shield cards that absorb a cascade wave; radioactive hazard cells
• Animated detonation waves rendered in Compose; clean state management

A BitTorrent stream-while-downloading engine: paste a magnet link and playback begins after a few seconds of prebuffering — no waiting 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 + 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
