--- title: "Projects — Shreyansh Kumar Singh" description: "Nine projects, each with a case study." url: https://www.shreyanshkumarsingh.com/projects author: Shreyansh Kumar Singh updated: 2026-10-08 --- # Projects by Shreyansh Kumar Singh — AI & full-stack case studies ## [Sarthi: an AI relationship-manager copilot for banking](https://www.shreyanshkumarsingh.com/projects/sarthi-rag-banking-copilot) 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. ## [Nythera: autonomous penetration testing that proves every finding](https://www.shreyanshkumarsingh.com/projects/nythera-ai-penetration-testing-agent) 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. ## [HallogenAI: verifying bug fixes by evidence, not by commit](https://www.shreyanshkumarsingh.com/projects/hallogenai-multi-agent-bug-fix-verification) 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. ## [BookVerse AI: step inside any book — even with no API key](https://www.shreyanshkumarsingh.com/projects/bookverse-ai-book-summaries) 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. ## [Antarang: a walkable 3D museum of Indian and world art](https://www.shreyanshkumarsingh.com/projects/antarang-3d-art-museum-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. ## [The Evolution: four physics simulators, one HTML file each](https://www.shreyanshkumarsingh.com/projects/the-evolution-physics-simulators) 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. ## [The Collector's Pulse: an AI-curated newsroom for collectors](https://www.shreyanshkumarsingh.com/projects/collectors-pulse-ai-newsroom) 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. ## [VaultIQ: ASP.NET Core 8 and Angular 18 in Clean Architecture](https://www.shreyanshkumarsingh.com/projects/vaultiq-dotnet-angular-clean-architecture) 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. ## [Revuelto: Assembled — a car that builds itself as you scroll](https://www.shreyanshkumarsingh.com/projects/revuelto-scroll-canvas-animation) For scroll-scrubbed product animation, a canvas image sequence beats a
