Skills of Shreyansh Kumar Singh
AI & full-stack engineering

Shreyansh Kumar Singh works across applied AI and production full-stack engineering — RAG pipelines and LLM agents on one side; C#, ASP.NET Core, SQL Server and Angular on the other; Next.js, Flutter and React Three Fiber in between. Every skill below links to the project or production work where he used it.

Applied AISystems with the model inside the loop from the first design — and audited afterwards.

  • RAG pipelinesEmbeddings, vector storage, retrieval and generation as separately testable modules. — Sarthi, BookVerse AI
  • Embeddings & vector retrievalVector retrieval over document corpora, on Supabase. — Sarthi
  • LLM agent loopsAgents that act, observe and verify before reporting. — Nythera
  • Multi-agent systemsEight specialized agents coordinating bug-fix verification. — HallogenAI
  • Prompt & context designGrounding answers in source text; graceful fallback when no model is available. — BookVerse AI
  • Groq, Gemini, OllamaHosted and local models, chosen by cost and reliability. — The Collector's Pulse, BookVerse AI
  • OCR (Tesseract)Text extraction feeding document pipelines.

Back endAPI-first: the contract and the schema come before the screens.

  • C# · ASP.NET Core 8 · ASP.NET Web APIProduction APIs for Classroom+, PIBM and Dada Udyogini. — PIBM journal, Dada Udyogini
  • Clean Architecture · EF CoreFour-layer .NET 8 solution with an Angular 18 Signals front end. — VaultIQ
  • SignalRReal-time orchestration of the DadaLoad load-test fleet. — Dada Udyogini
  • Python · FastAPI · Pydantic v2 · SQLAlchemyAgent back ends and security tooling. — HallogenAI, Nythera
  • REST API designTyped contracts shared between API and client models.

Front endTyped models, validated reactive forms, and motion only where it earns its place.

  • Angular 16–18 · Signals · RxJSAdmin, student and faculty apps; reactive forms; Angular Material. — Classroom+ admin, Classroom+ faculty
  • Next.js (App Router) · React 19 · TypeScriptFive Next.js AI projects, from RAG to an AI-curated newsroom. — Sarthi, The Collector's Pulse
  • Tailwind CSS · Bootstrap · shadcn/RadixDesign systems written as tokens before components.
  • GSAP · Lenis · Framer MotionScroll-driven motion without scroll-jacking. — Revuelto

DataSchema first, then the API that serves it.

  • SQL ServerSchemas behind the Classroom+ platform and PIBM portal. — PIBM journal
  • PostgreSQL · RedisDada Udyogini and Vidur back ends. — Dada Udyogini, Vidur
  • Prisma · Drizzle · Supabase · NeonTyped data layers for the Next.js projects. — Antarang

MobileFlutter clients on the same .NET back ends.

  • Flutter · Dart · flutter_bloc · go_routerSeller and buyer marketplace apps; a multi-tenant request-tracking app. — Dada Udyogini, Vidur
  • Firebase SDK · Google Maps SDKData layer, OTP and logistics tracking. — Dada Udyogini

3D & graphicsWalkable spaces and simulations, tuned for perceived smoothness.

  • React Three Fiber · Three.jsA walkable 3D museum of Indian and world art. — Antarang
  • Canvas 2D · N-body & particle simulationFour zero-dependency physics simulators, ~5,000 lines. — The Evolution
  • Scroll-driven image sequences110 WebP frames scrubbed to scroll on a 5.5 MB page. — Revuelto

SecurityA finding without physical evidence is discarded, not downgraded.

  • OWASP Top 10 · CWE mapping · PTES workflowNine vulnerability classes across a seven-phase workflow. — Nythera
  • Validated exploitationEvery finding confirmed with evidence before it's reported. — Nythera
  • Security self-audit (P0–P3)Published audit of his own system, worst finding first. — Sarthi
  • Auth hardening · rate limitingDefault-off dangerous capabilities, host-locked scanning.

Cloud & toolingShip it, measure it, and prove capacity before launch day.

  • Microsoft AzureApp Service and Static Web Apps; right-sized against real traffic. — Dada Udyogini
  • AWS S3 · Firebase / Google CloudDocument uploads and mobile data. — PIBM journal
  • k6 load testing (distributed)DadaLoad: k6 orchestrated across 10 machines before a fixed launch date. — Dada Udyogini
  • Docker · GitHub Actions · PlaywrightContainerized tools, CI deploy gates, browser automation. — HallogenAI

LanguagesFive in production use.

  • TypeScript · JavaScriptNext.js, React, Angular.
  • C#.NET 8 and ASP.NET Core.
  • PythonAgents and security tooling.
  • SQLSQL Server and PostgreSQL.
  • DartFlutter apps.
