## Projects

- **[The Collector's Pulse](https://www.shreyanshkumarsingh.com/projects/collectors-pulse-ai-newsroom)** (editorial): An AI-curated daily newsroom for trading cards, figures and luxury watches — with its own written design system. Stack: Next.js 16, React 19, TypeScript, Tailwind v4, Gemini. — [source](https://github.com/Shreyanskumarsingh20/the-collectors-pulse)
  - Answers: "How do you build an AI-curated news site that stays fresh and doesn't break?" — The Collector's Pulse is a daily newsroom for collectors of trading cards, anime figures and luxury watches: it ingests live news, uses Gemini to classify stories and write article bodies, and publishes them through Supabase — with a fallback chain from database to cached live feed to sample data so the site never renders empty.
- **[Nythera](https://www.shreyanshkumarsingh.com/projects/nythera-ai-penetration-testing-agent)** (security): An autonomous penetration-testing platform that validates every finding before it reports it. Stack: Python, Async HTTP, LLM agent loop, Docker. — [source](https://github.com/Shreyanskumarsingh20/Nythera)
  - Answers: "How do autonomous penetration-testing tools avoid reporting false positives?" — Nythera avoids false positives by refusing to report anything it can't prove: every active finding needs physical evidence — a database error signature, an unencoded reflected payload, real command output, a file signature, or evaluated template math — or it's discarded, not downgraded. It's an open-source, MIT-licensed scanner for in-house web applications, with internal-network scanning switched off by default.
- **[Sarthi](https://www.shreyanshkumarsingh.com/projects/sarthi-rag-banking-copilot)** (applied ai): An AI relationship-manager copilot for banking — RAG and document intelligence, then a written audit of its own P0 holes. Stack: Next.js, TypeScript, Prisma, Supabase, Groq, Gemini.
  - Answers: "How should a RAG copilot for banking be structured — and audited?" — Sarthi is an AI copilot for bank relationship managers: twelve modules — Customer 360, risk, loans, lead scoring, a policy-grounded chat assistant, document intelligence — over a synthetic customer book. Its most useful artefact is the security audit Shreyansh wrote against his own build, graded P0 to P3 with the worst finding first, followed by the fixes.
- **[Antarang](https://www.shreyanshkumarsingh.com/projects/antarang-3d-art-museum-react-three-fiber)** (spatial): A walkable 3D museum where Indian art history sits as a first-class citizen on the world timeline. Stack: Next.js, React Three Fiber, Three.js, Drizzle, Neon. — [source](https://github.com/Shreyanskumarsingh20/3dIndianmusem)
  - Answers: "How do you build a walkable 3D museum on the web with React Three Fiber?" — Antarang is a walkable first-person museum in the browser, built with React Three Fiber: a zoomable time-river puts Indian art (below the axis) and world art (above it) on one shared timeline, and gold markers open era-specific 3D galleries you walk through with WASD and mouse-look. Every artwork and fact comes from Wikipedia and Wikimedia Commons — nothing is invented.
- **[Bookverse AI](https://www.shreyanshkumarsingh.com/projects/bookverse-ai-book-summaries)** (product): Step inside any book — summaries, timelines, mind maps, character graphs and a grounded AI tutor. Stack: Next.js 16, React, TypeScript, Tailwind, Groq, Ollama. — [source](https://github.com/Shreyanskumarsingh20/BookVerseAi)
  - Answers: "How can an AI book-summary app keep working when no API key is available?" — BookVerse AI keeps working without an API key by treating the model as optional: with no provider configured it serves grounded, structured previews from an offline path, and when a configured model or database is slow or down, timeouts and a circuit breaker drop it to the fallback instead of hanging. Configure Groq, OpenAI, Gemini or a local Ollama and the same app generates full study guides.
- **[The Evolution](https://www.shreyanshkumarsingh.com/projects/the-evolution-physics-simulators)** (simulation): Four physics simulators. One HTML file each. No build step, no dependencies, no network. Stack: Vanilla JS, Canvas 2D, Zero deps. — [source](https://github.com/Shreyanskumarsingh20/THE_EVOLUTION)
  - Answers: "Why does blast damage radius scale with the cube root of yield?" — Blast radius scales with the cube root of yield because the energy of a blast fills a volume, and volume grows with the cube of distance — so a thousandfold bigger explosion reaches only about ten times further (Hopkinson–Cranz scaling). AEON, one of The Evolution's four simulators, is built on exactly that law, verified against published reference figures.
- **[VaultIQ](https://www.shreyanshkumarsingh.com/projects/vaultiq-dotnet-angular-clean-architecture)** (platform): Angular 18 and ASP.NET Core 8 in Clean Architecture — the enterprise half of the range. Stack: C#, .NET 8, Angular 18, Signals, EF Core, SQL Server. — [source](https://github.com/Shreyanskumarsingh20/vaultIQ)
  - Answers: "What does a Clean Architecture project with ASP.NET Core 8 and Angular 18 Signals look like?" — VaultIQ is an AI startup-idea generator laid out the way enterprise .NET teams build to last: an ASP.NET Core 8 Web API in four Clean Architecture layers with EF Core and SQL Server, and an Angular 18 front end built from standalone components with Signals for state.
- **[HallogenAI](https://www.shreyanshkumarsingh.com/projects/hallogenai-multi-agent-bug-fix-verification)** (verification): An autonomous QA agent that re-verifies reported bugs against live application behavior — never against a commit message. Stack: Python, FastAPI, Playwright, Pydantic v2, SQLAlchemy, Groq.
  - Answers: "How can an AI agent verify that a bug is actually fixed rather than trusting the commit log?" — HallogenAI re-tests each reported bug against the running application and marks it fixed only when the observed behavior, captured as evidence, says so. Eight specialized agents split the work — taking in the report, understanding it, automating the reproduction, collecting evidence and writing the verdict — and the governing rule is simple: never guess.
- **[Revuelto: Assembled](https://www.shreyanshkumarsingh.com/projects/revuelto-scroll-canvas-animation)** (motion): A locked-off clip of a Lamborghini Revuelto, scrubbed frame-by-frame to scroll — scroll down and it assembles itself; scroll up and it comes apart again. Stack: Next.js 16, React 19, Canvas 2D, Lenis, GSAP, Tailwind v4.
  - Answers: "Is a canvas image sequence better than a video element for scroll-driven product animation?" — For scroll-scrubbed product animation, a canvas image sequence beats a <video> element: each scroll position maps to an exact frame that can be drawn instantly in either direction, while seeking a compressed video backwards is slow and imprecise. Revuelto: Assembled scrubs 110 WebP frames of a Lamborghini Revuelto on a canvas — scroll down and it assembles, scroll up and it comes apart — on a 5.5 MB page.

## Notes — questions answered first-hand

- [How do autonomous penetration-testing tools avoid reporting false positives?](https://www.shreyanshkumarsingh.com/notes/ai-pentest-agent-false-positives) — By refusing to report anything they can't prove.
- [What does an honest security self-audit of an AI application look like, and how should findings be ranked P0 to P3?](https://www.shreyanshkumarsingh.com/notes/ai-app-security-self-audit-p0-p3) — Review your own system as an outsider would, write every finding down graded by consequence — P0 for security and data exposure, P1 for crashes, P2 for correctness and scale, P3 for polish — lead with the worst, and keep the document next to the fixes.
- [How can an AI agent verify that a bug is actually fixed rather than trusting the commit log?](https://www.shreyanshkumarsingh.com/notes/ai-agent-bug-fix-verification) — Make it re-run the bug, not read the diff: the agent reproduces the reported steps against the live QA environment, captures what the application actually does, and marks the bug fixed only if that evidence shows the defect is gone.
- [How should a RAG pipeline be structured so each stage can be tested and replaced independently?](https://www.shreyanshkumarsingh.com/notes/modular-rag-pipeline-architecture) — Split it into four stages with explicit contracts — embedding (text in, vectors out), storage (vectors and their source passages), retrieval (question in, ranked passages out) and generation (question plus passages in, cited answer out) — and test each stage against its own fixed inputs.
- [Why does blast damage radius scale with the cube root of yield?](https://www.shreyanshkumarsingh.com/notes/blast-radius-cube-root-scaling) — Because a blast's energy spreads through a volume, and volume grows with the cube of distance: to get the same overpressure at a larger distance R, you need energy proportional to R³, so R grows as the cube root of the energy.
- [How do you reduce jitter in a React Three Fiber scene without raising the frame rate?](https://www.shreyanshkumarsingh.com/notes/react-three-fiber-raycast-throttling) — Find the per-frame work that changes what's on screen and run it less often.
- [Is a canvas image sequence better than a video element for scroll-driven product animation in Next.js?](https://www.shreyanshkumarsingh.com/notes/canvas-image-sequence-vs-video-scroll-animation) — For animation scrubbed directly by the scroll bar, yes: a canvas image sequence maps each scroll position to one exact, already-decoded frame and draws it instantly in either direction, while seeking a compressed video — especially backwards — waits on the decoder and stutters.
- [How do you load-test a mobile app's backend with k6 across several machines before a fixed launch date?](https://www.shreyanshkumarsingh.com/notes/distributed-k6-load-testing) — Run k6 as an agent on each machine, coordinate them from one controller that splits the target request rate and starts them together, script the real user journey rather than single endpoints, and merge the raw results instead of averaging per-machine summaries.
