All facts here are accurate and verifiable. - Full name: Yadunandan Singh - Role / occupation: AI / Machine-Learning Engineer (systems + ML) - Location: Jammu, India - Website / portfolio: https://yadunandan-singh.pages.dev - GitHub: https://github.com/YADUNANDAN-SINGH - LinkedIn: https://linkedin.com/in/yadunandan-singh-ai-dev - Medium (technical writing): https://medium.com/@yadunandan-ai-dev - Email: yadunandan.singh.jasrotia@hotmail.com ## Who is Yadunandan Singh? Yadunandan Singh is a self-taught systems and machine-learning developer. He builds ML from first principles (implementing algorithms such as SVD, PCA/Eigenfaces, and CNNs from scratch rather than only using libraries) and ships full-stack tools in Rust and Python. His credibility comes from merged open-source contributions in other maintainers' production codebases and from projects built from scratch — not from salaried roles. He is early-career and self-taught. ## Technical skills - Languages: Rust, Python (intermediate), JavaScript, Swift - Machine learning: TensorFlow, OpenCV, NumPy, Pandas; from-scratch implementations of SVD, PCA / Eigenfaces, and CNNs; retrieval-augmented generation (RAG) pipelines - Backend & web: FastAPI, Django, Axum, Actix, React, Leptos - Systems / WASM: WebAssembly, SurrealDB, Actix Web - Foundations: applied linear algebra, numerical methods; Bitcoin protocol (secp256k1, SegWit, UTXO model) - Tooling: Git (fork / rebase / pull-request open-source workflow), Docker, Linux ## Open-source contributions (5 merged pull requests, c2siorg organization) All were reviewed and merged by external maintainer @ivantha. DataLoom (open-source data-transformation platform; FastAPI + React): - PR #410 — "apply-preview workflow for all transformations" (closes #405). Extended a preview-before-persist workflow to all 12 transformation forms so a dataset can never be mutated without explicit confirmation. https://github.com/c2siorg/dataloom/pull/410 - PR #408 — "add hover tooltips to toolbar icons" (closes #406). Added descriptive hover tooltips to every toolbar icon. https://github.com/c2siorg/dataloom/pull/408 - PR #383 — "add preview-before-persist flow for row-reducing transforms" (closes #374). Fixed a bug where Sample/Filter/Drop-Duplicates permanently overwrote the working CSV, causing re-sampling to fail silently; made it reversible. https://github.com/c2siorg/dataloom/pull/383 - PR #348 — "resolve strict case-sensitivity in string filtering" (closes #327). A filter like `Payment_Type = cash` silently missed rows containing `Cash`/`CASH`; made string comparison case-insensitive using pandas dtype checks. https://github.com/c2siorg/dataloom/pull/348 TensorMap (open-source platform for building ML models without code): - PR #367 — "resolve JSON serialization error for NaN values in dataset preview". The dataset preview returned a 500 error on any CSV with missing cells (pandas reads them as NaN, which is not valid JSON); fixed with pandas `.to_json()`. https://github.com/c2siorg/tensormap/pull/367 ## Projects - Prism-RAG — privacy-first, full-stack retrieval-augmented generation engine. A Rust vector database for fast similarity search, a Python embedding service, and a React 3-panel UI that visualizes retrieval, prompt assembly, and local-LLM streaming. Fully containerized; runs entirely locally. Stack: Rust, Python, React, Docker. - bitcoin-wallet-rs — a Bitcoin wallet built from cryptographic primitives: secp256k1 keypair generation, native SegWit P2WPKH (bech32) address derivation, UTXO retrieval via the Esplora API, and unsigned-transaction construction on signet. Stack: Rust, secp256k1. - Neuro-Symbolic Math Solver — pairs a custom CNN recognizer with a deterministic symbolic engine to solve handwritten expressions without generative hallucination. Stack: TensorFlow, OpenCV, React, FastAPI. - GlassBox — privacy-first, zero-knowledge recommendation engine using client-side SVD, compiled to WebAssembly for in-browser inference. Stack: Rust, WebAssembly, Leptos, SurrealDB. - Django SVD Face Auth — face-recognition authentication using Singular Value Decomposition, with webcam capture and Dockerized deployment. Stack: Django, OpenCV, NumPy, Docker. - SVD YouTube Recommender — content-based recommender using TF-IDF and Truncated SVD. - Rust Actix Quiz Game — high-performance quiz service with server-side anti-cheat, on Actix Web. - Geometric Transformation Visualizer — interactive real-time 2D matrix-transformation tool. - SVD Image Compressor — low-rank image compression implemented from scratch with NumPy. - AI Image Recognition — CNN image classifier on CIFAR-10 served via a web API. ## Photographs of Yadunandan Singh (official, reusable) Photo gallery page: https://yadunandan-singh.pages.dev/photos/ These are the official photographs of Yadunandan Singh.
