I'm Shreyan, a computer science student specialising in AI & ML at SRM IST, Chennai. Most of what I build sits where models meet real systems: vision pipelines that have to keep up with a webcam, LLM tools that are honest about what they don't know, and backends that survive retries, restarts and bad input.

I like understanding how things work underneath, so I also end up writing terminal tools in Rust, Android apps in Kotlin, game mods and the occasional browser game.

_{Python · OpenCV · MediaPipe · NumPy · asyncio · Whisper}

A webcam module for a ticket-kiosk agent that decides when the person in front of it is speaking, using only video. It picks one primary user out of everyone in frame (face area and centrality, then IoU tracking so a bystander can't take over), measures lip motion from MediaPipe landmarks, and emits debounced speech_start / speech_end events. The interesting part is the decision logic: separate start and end thresholds with hold times so it doesn't chatter, and lost faces treated as uncertainty rather than silence. An optional local Whisper stream transcribes only while the visual state says someone is talking. A standalone version exposes the pipeline as bounded asyncio.Queue stages behind a small async API.

_{Python · TypeScript · Tree-sitter · Docker}

Local-first codebase intelligence. Instead of pasting files into a model and trusting its guess, it analyses the repository first: Tree-sitter and ast extract symbols, imports and calls into a dependency graph whose edges are marked resolved or unresolved, and search combines lexical, semantic and structural signals. A language model is optional and only explains what the analysis found. Runs offline by default.

_{FastAPI · PostgreSQL · SQLAlchemy · Alembic · Docker · GitHub Actions · Prometheus · Grafana}

A deliberately small API used to build the full delivery pipeline around it: unit, integration and container smoke tests, Trivy image scanning, publishing to GHCR only after the built image passes its own scan, scripted deployment with automatic rollback, real liveness/readiness separation, and a Prometheus and Grafana stack.

_{FastAPI · async SQLAlchemy · PostgreSQL · React · Docker}

Priority queues with concurrency limits, fixed / linear / exponential retry policies, a dead-letter queue, worker heartbeats with graceful shutdown, and delayed and cron-scheduled jobs, with a React dashboard on top.

_{TypeScript · React · Phaser 3 · Web Audio}

An endless runner where React and Phaser never touch each other's objects and talk only through a small typed event bus. Phaser is loaded lazily, which cut the initial bundle from 1.58 MB to 382 KB. Every visual is drawn procedurally and every sound is synthesised, so the repository has no image or audio files. Includes a seeded daily challenge and a ghost replay of your best run.

• PINNs vs neural operators — when does training a neural operator beat re-solving parametric PDEs with FEM or retraining PINNs? A benchmark across Burgers, Darcy flow and heat conduction comparing PINN, DeepONet, FNO and PINO against FEM. Still in the research-foundation phase; no models yet.
• Ferrite — a Rust TUI system monitor at v0.2: CPU, memory, disk and network panels, a sortable process table and threshold alerts. Next up: decoupling collection from the render loop, and export.
