• Continued contributing to POSIFY, a production-grade parking management solution, after successfully completing my internship on the same team.
• Developed new backend and frontend features while improving existing functionality through refactoring, performance enhancements, and bug fixing.
• Designed and implemented new REST APIs and contributed to distributed, event-driven communication between internal and external services using NATS.
• Worked closely with the CTO, developers, and QA team to prepare the platform for customer demonstrations and real-world deployment scenarios.
• Performed extensive validation and testing in production-like environments, ensuring reliable integration with parking infrastructure and external microservices.

• Contributed to the development of POSIFY, an integrated parking management solution composed of a Point of Sale (POS) system and a Backoffice platform.
• Designed and implemented backend services and REST APIs in Go (Gin), focusing on scalable architecture, business logic, and PostgreSQL data management.
• Developed React/TypeScript interfaces for both the POS and Backoffice applications, delivering operational workflows and administrative features.
• Built event-driven microservices using NATS to synchronize data with external systems and support real-time communication across the platform.
• Developed a dedicated microservice for EPSON receipt printers and integrated the POS with parking hardware, including the PMS, printer, tariff, barrier, and camera systems, through HTTP, Server-Sent Events (SSE), and NATS.
• Implemented authentication, role-based access control (RBAC), dashboards, and configuration management while collaborating on the overall system architecture.
• Containerized services with Docker/Docker Compose and took part in the deployment workflow, publishing application images to a private Nexus registry for validation in the company's testing environment.

Focused on securing IT systems, networks, and embedded systems. Builds on my backend engineering background with a security-first lens — network and infrastructure security, secure system design, and risk management for real-world ICT environments.

A broad, hands-on foundation across the core of computer science — computer architecture, operating systems, algorithms and data structures, databases, computer networks, full-stack web development, and an introduction to artificial intelligence and machine learning. That mix of low-level systems knowledge and modern software engineering practice — combined with real production experience at Asteroidea during my final year — shaped how I approach backend engineering today: understanding not just how to build a system, but how it actually runs underneath.
