Hello! I'm Said, a Computer Science student at MTUCI with a deep passion for backend engineering. My journey has taken me from foundational programming concepts to designing and implementing complex, distributed-ready systems. I thrive on building software that is not just functional, but also robust, scalable, and a pleasure to maintain.
My main focus is on the Java & Spring ecosystem, where I enjoy architecting clean, modular applications. This culminated in my latest project, a fully-fledged e-commerce platform, which served as my personal masterclass in applying modern architectural patterns, comprehensive testing strategies, and CI/CD automation.

A complete e-commerce MVP designed with a modular monolith architecture, ready for a seamless transition to microservices. This project demonstrates a deep understanding of scalable system design and modern development practices.
- 🏛️ Architectural Blueprint: Implements a modular monolith with a decoupled, event-driven core, making it ready for a seamless evolution into a distributed system.
- 🧪 Production-Grade Testing: Features a robust test suite with JUnit, Mockito, and Testcontainers, validating everything from business logic to database interactions and event flows.
- 🔄 CI/CD Automation: Fully automated build and test pipeline with GitHub Actions.
- 💾 Optimized Dual-Database Design: Leverages the strengths of PostgreSQL for transactional integrity and Redis for high-performance caching of ephemeral data like user carts.
- 🔐 JWT-Based Security: Role-based access control (USER/ADMIN) with Spring Security.
- 🗎 Database Versioning with Flyway.
A distributed chat system built to explore core microservice patterns, including centralized authentication and inter-service communication via REST and WebSockets.
- 🔑 AuthService handles registration & login.
- 💬 ChatService offers REST & WebSocket (STOMP) endpoints for messaging.
- 🛡️ common-security module for centralized JWT authentication components.
- 🗄️ Spring Data JPA + PostgreSQL for persistence.
- 🏗️ Modular architecture to eliminate code duplication.
A comprehensive, full-stack application for booking meeting rooms, built with a production-ready mindset.
- 🏗️ Production-Ready Docker Environment: Features multi-stage Docker builds for both the React frontend and Spring Boot backend, orchestrated with Docker Compose and fronted by an Nginx reverse proxy.
- 🌐 Modern Full-Stack Architecture: Combines a reactive React 19 (TypeScript) frontend with a robust Spring Boot 3 REST API backend.
- ✅ Automated CI & Code Quality: Integrated GitHub Actions pipeline that runs tests, static analysis (PMD, SpotBugs), and code formatting (Spotless) on every commit.
- 📅 Core Functionality: Secure user authentication (JWT), an interactive room availability schedule, and personal booking management.
I'm driven by a passion for excellence and enjoy applying my skills in competitive environments. Some of my key accomplishments include:
- 🥇 1st Place, University Java Programming Olympiad (MTUCI, 2024) — Secured the top position, demonstrating advanced proficiency in Java algorithms and problem-solving.
- 🏆 Finalist, "Battle of Universities" at YOUNG CON 2025 — Recognized as a top contender in a major inter-university programming competition held at a national IT conference.
- 🏅 Award Winner, Algoritmika International Junior Hackathon — Achieved a top-ranking position in a global hackathon for participants under 17.
I'm always open to discussing new technologies, collaborating on interesting projects, or just chatting about software engineering. Feel free to reach out!
