From low-level silicon to the global edge.

Public Android 15 & 16 builds for the Redmi Note 12 Pro 5G (ruby / rubyx) compromised on privacy, lacked control over low-level framework APIs, or failed strict enterprise integrity checks.

Compiled Android 16 (android-16.0.0_r4) from source on custom clang-r563880c with 10 ingested device/kernel trees. Diagnosed and resolved the fatal MediaTek bootloop using RAM console-ramoops-0 inspection to patch ln8000_probe.

Modern search requires Generative Engine Optimization (GEO) auditing across AI search engines, but running multi-step website collectors typically requires heavy headless server clusters.

Architected a serverless auditing platform utilizing Cloudflare Workflows, Browser Rendering API, D1 distributed SQL, and R2 object storage. 21 collectors run with zero servers to patch and zero operational overhead.

Traditional notes apps organize thoughts into rigid hierarchical lists or folders. Ideas are temporal and spatial; they need an infinite canvas where timestamps naturally determine placement.

Engineered an infinite 2D thought wall in Flutter where notes spiral outward from their creation timestamp. Implemented offline-first sync to Cloudflare D1 with monotonic timestamps and tombstone CRDTs to prevent resurrection of deleted notes.

Commercial screen-time blockers are easily bypassed by toggling device settings or killing background services. Users need an OS-level enforcement engine that respects spatial context.

Built an Android system app combining Device Admin (BIND_DEVICE_ADMIN) with an Accessibility Service. Evaluates a pure LockEvaluator combining 50m–500m GPS geofencing, Wi-Fi SSID gates, and productive redirects.

Timber traders and forestry managers measure standing trees by eye and calculate volume manually, leading to massive financial discrepancies and estimation errors.

Developed Tashkesh, an ARCore and Sceneview 3D HUD that raycasts from tree base to crown to calculate height in real time. Automatically applies the Hoppus quarter-girth formula: V = ⌊G² × (H/2) / 2304 × 100⌋ / 100.

Smartphones are flooded with notification badges, docks, widgets, and settings icons that trigger mindless phone unlocking and digital distraction.

Engineered an Android home screen with zero buttons. Users navigate apps by dragging their thumb along a 5-node rotary radial arc with non-linear scale interpolation and an apex crystal lens, snapping into a 3-second zero-motion linger.

Local shopkeepers who sell goods on credit maintain messy paper notebooks (udhar khata) that are prone to calculation errors, lost pages, and customer disputes.

Built a high-reliability double-entry credit ledger for shops. Running customer balances are always recomputed dynamically from raw entries (auto-healing). Includes downloadable statements and soft-delete trash.
