System Requirements Document (SRD)

Project Name: infini-questions

1. Introduction

The infini-questions platform is an innovative web and mobile application designed to make coding education accessible, engaging, and practical for users of all skill levels, especially non-coders. By leveraging interactive visualizations, step-by-step explanations, and multiple algorithmic approaches, the platform aims to demystify complex programming concepts and foster a deeper understanding of coding principles.

This document outlines the system requirements for infini-questions, including functional and non-functional requirements, user personas, design concepts, and technical considerations. The platform is tailored to meet the needs of users in India (IN) and beyond, with a focus on delivering an intuitive, visually rich learning experience.

2. System Overview

The infini-questions platform will allow users to input any coding-related question and receive detailed, step-by-step visual explanations of solutions. The system will:

• Support free-form question input, identifying the type of problem and generating relevant explanations.
• Provide multiple algorithmic solutions (3-5 approaches) for the same problem, highlighting their pros, cons, and use cases.
• Use dynamic visualizations such as time graphs, tables, maps, and animations to explain concepts.
• Cater to users of varying skill levels (beginner, intermediate, advanced) with tailored explanations.
• Focus on practical, real-world examples to enhance learning.

The platform will be available as both a web application and a mobile app, ensuring accessibility and convenience for users.

3. Functional Requirements

As a User:

• I should be able to input any coding-related question in free-form text.
• I should receive step-by-step visual explanations of the solution.
• I should see multiple algorithmic approaches (at least 3) for the same problem.
• I should be able to view visualizations such as time graphs, tables, maps, and animations.
• I should be able to adjust the complexity level of explanations (beginner, intermediate, advanced).
• I should be able to pause, play, and step through animations of algorithms.
• I should be able to filter explanations by algorithm type or visualization format.

As an Admin:

• I should be able to manage a library of curated questions and explanations.
• I should be able to monitor user activity and feedback to improve the platform.
• I should be able to update or add new algorithms and visualizations.

4. User Personas

1. Beginner

• Description: A non-coder or someone new to programming, looking for simple, practical explanations.
• Needs: Step-by-step guidance, basic terminology, and clear visualizations.

2. Intermediate Developer

• Description: A developer with some experience, aiming to strengthen their fundamentals.
• Needs: Multiple algorithmic approaches, performance comparisons, and practical examples.

3. Advanced Developer

• Description: An experienced developer preparing for interviews or tackling complex problems.
• Needs: Detailed algorithmic analysis, advanced visualizations, and optimization insights.

4. Admin

• Description: A platform manager responsible for content curation and system maintenance.
• Needs: Tools for managing content, monitoring user activity, and updating features.

5. Visuals Colors and Theme

Unique Color Palette for infini-questions:

• Background: #F5F9FF (soft sky blue for a calm, educational atmosphere)
• Surface: #FFFFFF (clean white for content areas)
• Text: #2C3E50 (dark slate for readability)
• Accent: #FF6F61 (vibrant coral for interactive elements and highlights)
• Muted Tones: #B0BEC5 (light gray for secondary elements and borders)

6. Signature Design Concept

Interactive Algorithm Playground

The homepage of infini-questions will feature an Interactive Algorithm Playground, a bold and unforgettable design concept that immediately immerses users in the platform's capabilities.

Key Features:

• Dynamic Visualization Hub: The homepage will display a rotating carousel of live algorithm visualizations (e.g., sorting animations, graph traversals). Users can interact with these visualizations directly—adjusting parameters like input size or complexity level to see real-time changes.
• Step-by-Step Panels: Below the carousel, a split-screen interface will show the algorithm's pseudocode on one side and a synchronized visualization on the other. Users can hover over lines of code to highlight corresponding steps in the animation.
• Interactive Animations: Animations will include micro-interactions, such as elements "lighting up" when selected or nodes in a graph pulsating to indicate traversal order.
• Color Shifts: The background subtly shifts hues based on the algorithm type (e.g., blue for sorting, green for graph traversal), creating an engaging and intuitive visual experience.

This design will captivate users from the moment they land on the platform, showcasing the power of visual learning in coding education.

7. Non-Functional Requirements

• Performance: The platform must handle up to 10,000 concurrent users with minimal latency.
• Scalability: The system should be designed to scale horizontally as user demand grows.
• Accessibility: The platform must comply with WCAG 2.1 standards to ensure usability for all users.
• Localization: Support for Indian English and other regional languages in future phases.
• Security: Implement robust authentication and data encryption to protect user information.

8. Tech Stack

Frontend:

• React for Web
• React Native for Mobile App

Backend:

• Python
• FastAPI

Database:

• MySQL (with Alembic for migrations)

AI Models:

• GPT 5.4 for user-friendly responses
• Claude 4.6 Opas for academic or coding work
• Gemini 3.1 Pro for friendly responses

AI Tools:

• Litellm for LLM Routing
• Langchain

Orchestration:

• Docker and Docker-Compose for local development
• Kubernetes for server-side orchestration

9. Assumptions and Constraints

• The platform will initially focus on algorithms and data structures, expanding to other topics in later phases.
• Visualizations will prioritize clarity and simplicity, avoiding overly complex designs that may confuse beginners.
• Free-form question input will rely on NLP models, which may require iterative improvements based on user feedback.
• The MVP will support English only, with localization planned for future updates.
