Software Engineering

Java JUnit 5 Design Patterns

Flight & Reservation Management

Java domain model for flight and reservation management, focused on business rules, design patterns, lifecycle management, and unit testing.

Modeled airlines, flights, airports, routes, passengers, payments, reservations, and their business invariants
Applied Strategy for fare calculation, State for the reservation lifecycle, and Factory to centralize reservation creation
Built JUnit 5 tests covering validation, pricing, payment logic, domain invariants, and reservation state transitions

Backend Engineering

Django SQLite Access Control

Collaborative Task Backend

Multi-user Django backend focused on relational data modeling, collaborative workflows, and view-level authorization.

Modeled users, teams, tasks, and hierarchical subtasks using ForeignKey, ManyToMany, and directed self-referencing relationships
Enforced task permissions based on creator ownership, direct assignment, team membership, and superuser status
Used Django signals to automate profile creation and maintain relationship consistency when users, teams, or tasks are deleted

Data Systems / Database Systems

Java B-Tree Indexing

B-Tree Indexing Engine

In-memory Java indexing engine implementing balanced B-Tree storage for efficient key-value retrieval and structured queries.

Implemented key-value insertion with recursive leaf and internal node splitting while maintaining a balanced B-Tree structure
Added exact lookup, range queries with subtree pruning, and case- and accent-insensitive prefix search
Indexed 34,980 French municipality records and measured index build and lookup performance

Supporting Projects

Additional projects covering data processing, compiler construction, software architecture, and algorithmic optimization.

External Sorting Engine

Java External Sorting Multi-way Merge

Java external sorting engine for processing CSV datasets larger than available memory through sorted run generation and multi-pass merging.

Uses bounded-memory runs, disk-backed intermediate fragments, and multi-column ordering similar to SQL ORDER BY.

GitHub

Mini Compiler

Java ANTLR4 MVaP

Educational compiler project covering grammar design, parsing, semantic validation, typed expressions, and stack-based code generation.

Generates MVaP instructions for arithmetic, boolean, and rational expressions with variable and type handling.

Gomoku Game

Java Minimax Immutable State

Terminal Gomoku Game app with separated game logic, persistence, heuristic AI, and adversarial-search components.

Implements immutable game states and depth-limited Minimax with pluggable heuristic evaluation.

GitHub

Travel Web Page

HTML5 CSS3 JavaScript AJAX DOM

Responsive tourism website built with vanilla web technologies, interactive client-side behaviour, and accessibility-focused design.

Built DOM-driven form validation and dynamic user feedback, and integrated login and chat interfaces with backend CGI scripts using AJAX and JSON.
