Professional overview
Roman Daniel-Gabriel is a full-stack web developer based in Iași, Romania, with over 9 years of professional software engineering experience. I work directly with business owners, operation managers, and technical leads to build custom e-commerce platforms, warehouse management systems (WMS), manufacturing execution systems (MES), and high-speed web software that replace messy spreadsheets and fragile third-party tools.
My core philosophy centers on shipping software that yields measurable business results: top Core Web Vitals rankings, high conversion rates, effortless usability for non-technical staff, and long-term database stability.
Rather than relying on resource-heavy JavaScript frameworks, my primary architecture is built on PHP 8.4+, CodeIgniter 4, MariaDB/PostgreSQL, HTMX, Alpine.js, and Tailwind CSS. This stack is chosen specifically for sub-second loading speeds, exceptional technical SEO capabilities, low hosting overhead, and easy maintenance over time. I also deliver enterprise solutions using Symfony, API Platform, PrestaShop, and WordPress when a project requires it.
When you work with me, you communicate directly with the engineer building your product. Every project starts with a clear scope, an honest fit assessment, and transparent estimates, delivering custom software you own entirely without ongoing platform fees or agency lock-in.
Key specializations & core competencies
Warehouse & manufacturing software
Production-driven WMS, IMS, MES, and MRP systems featuring Bill of Materials (BOM) recipes, FIFO inventory depletion, and serialized unit tracking.
Technical SEO & Core Web Vitals
Near 100/100 Google Lighthouse performance scores, instant fuzzy search, llms.txt indexing feeds, and full WCAG 2 A/AA compliance.
Business & logistics integrations
Native connections for courier shipping, card payment gateways, automated invoicing (SmartBill, Saga, FGO, Nexus), and Google/Meta tracking feeds.
Legacy PHP modernization
Safe migrations from legacy PHP environments (PHP 5.6 to PHP 8.4+), strict PSR-12 code formatting, and SQL database optimization.
Infrastructure & support
Linux server administration, containerized Docker environments, automated 3-2-1 backup strategies, and long-term software maintenance.
