Silviu Stefaniu

I’m a “Senior Full-Stack Developer with 9+ years of experience building scalable web applications, ERPs, and SaaS platforms.” I bring a strong focus on PHP ecosystems (Laravel, Yii2) and API-driven architectures, paired with modern frontend development using Vue.js.

In my current role (Jan 2025 – Lisal Expert SRL, Bucharest, Romania), I contribute to a Laravel-based CRM and SaaS platform focused on invoicing and business automation. I automated invoicing workflows (including recurring invoices, penalties, and bank statement processing), and built and maintained scalable backend modules and APIs supporting multiple business processes, including a doctor booking system and SEO tools.

Previously, at Cardinal One SRL, I developed a generalized ERP system using Yii2 and ExtJS for a production facility—building multi-warehouse inventory management with automated stock recommendations and implementing document workflows for transfers, orders, sales, and inventory movements. I designed role-based access control (RBAC) and JWT-based API authentication, extended CRUD with custom actions (Export/Import, Validate, Transform, Scan), and optimized filtering and data handling for large datasets. I’ve also delivered Pimcore CMS solutions, and worked on real-time applications (including WebSocket chat) alongside B2B/invoicing and marketplace-style integrations.
