Amanpreet Singh Chalga

Architected a native Moodle LMS plugin using PHP, strictly adhering to enterprise modular architectures. Ported the Free Spaced Repetition Scheduler algorithm from Rust into a PHP-based scheduling engine. Engineered a "Just-In-Time" (JIT) scheduling architecture to compute memory intervals dynamically in O(1) time during user interactions. Integrated securely with Moodle's DML to enforce parameterized queries, automated CSRF token validation, and strict RBAC. Built a transactional bulk CSV import system.

Lead frontend dev for YoApp, a retail marketplace app (like Amazon), and contributed to iBill, a billing solution with barcode scanning. Lead a 3-member team using React Native + TypeScript, building reusable components, wishlist/cart/product APIs. For iBill, built Android UI & logic with Kotlin/Java. Translated Figma to production-ready layouts, integrated Redux Toolkit + Firebase for state & real-time data. Stack: Kotlin, Java, React Native, TS, Redux, Firebase.

Developed prototype Android application (Hello Tesa) to dynamically recolor walls in real-time camera feeds and static images. Implemented on-device image segmentation using TensorFlow (DeepLabV3) to automatically isolate wall boundaries. Implemented algorithmic approach using OpenCV, applying matrix blending to replace wall colors. Collaborated with a UX designer to translate wireframes from Figma into responsive native Android layouts, featuring custom touch-coordinate mapping for precise pixel selection.

Event-driven desktop application using Java and JavaFX. Designed custom progression algorithms, viability loops to evaluate valid forward/backward pathfinding based on real-time resource constraints. Used Gson library for data serialization to save and load application states. Built a protocol to prevent application crashes from corrupted files before injecting data into the game state. Built a customized file-logging system to generate event trails, enabling state recreation and debugging of logic errors.

A volunteer matching platform connecting citizens with community service. Implemented a Monorepo using Turborepo and pnpm to manage frontend (React/Vite) and backend (Express) packages in a single codebase. Backend: RESTful API in Node.js. Database: MongoDB. Languages: Java, Python, Kotlin, PHP, JavaScript (ES6+), TypeScript, SQL. Web & Frameworks: React, Node.js, Express.js, JavaFX. Tools: pnpm, TensorFlow Lite, OpenCV, ARCore, Git, Jest. Methodologies: Agile, Cross-Functional Teamwork, OOD.

Developed multiple Android applications from scratch including a dynamic, 500+ question form-based application for collecting cancer screening data. Used SQLite securely with web platforms via serverside APIs using OkHttp and JSON. Designed graphical monitoring systems for labor observation, implementing dynamic UI components like image-based user inputs. Participated in full testing lifecycle, writing JUnit test cases and assisting the QA team with automated web testing scripts using Selenium WebDriver.
