Software Engineer (Frontend-focused / Full-Stack)

PE BAS
Aug 2017 — Jul 2020

I am a frontend-focused software engineer with solid full-stack experience, specializing in building
scalable web applications, admin panels, and data-driven interfaces. My background includes
working across diverse domains such as event platforms, healthcare systems, public utilities, and
management tools, with a strong emphasis on user experience, performance, and maintainability.

I started my professional journey supporting and enhancing a CMS-based website built on Joomla
CRM, where I gained hands-on experience in maintaining legacy systems, improving UI components,
and implementing custom features using PHP, JavaScript, HTML, and CSS.

I then joined a startup project where I worked as a full-stack developer on a global event
aggregation platform. The system allowed users to discover events worldwide and purchase tickets. I
contributed to both frontend and backend development using Laravel, vanilla JavaScript, and
Google Maps API (including geolocation, map clustering, and event visualization). This role
strengthened my ability to build features from scratch, optimize performance, and collaborate in a
fast-paced environment.

My next experience involved working on a large-scale medical system, where I was primarily
focused on frontend development using Ext JS. I developed complex, data-heavy interfaces and
dashboards, ensuring high performance and usability. On the backend side, I worked with a custom
PHP framework and was responsible for writing and optimizing complex Oracle SQL queries, which
were used to generate detailed analytical reports exported to Excel. This role required deep attention
to data processing and performance optimization.

I continued collaborating with the same client on a public utilities (housing and communal services)
project, where I worked with a slightly modernized stack. I contributed to improving the frontend
architecture, maintaining legacy code, and implementing new features while ensuring system stability.

Most recently, I worked on an admin panel and mobile application backend for an exhibition center
management system. I was responsible for developing the frontend of the admin panel and designing
RESTful APIs using Laravel to support both the admin interface and mobile application. My work
included building intuitive UI components, managing data flows, and ensuring seamless integration
between frontend and backend systems.

Key technologies and tools:
JavaScript (ES6+), HTML5, CSS3, Ext JS, Laravel, PHP, REST API, MySQL, Oracle, Google Maps
API, Git, AJAX

I bring a strong combination of frontend expertise and backend understanding, enabling me to
deliver efficient, user-friendly solutions and effectively communicate across teams.
