I build resilient PHP systems, database synchronization engines, and scalable full-stack applications.

At MSA IP LAW, I build high-performance synchronization systems between Microsoft SQL Server and MySQL for critical IP assets. I've developed a Python SQL transpiler and migration engine, self-healing reconciliation workflows, fault-tolerant recovery pipelines, and a real-time administrative control center.

Previously at Paragraf Lex, I led a team of four developers while remaining hands-on with Laravel, Vue.js, database architecture, authentication, newsletters, invoicing, and role-based access control. I improved project delivery efficiency by 30%, mentored interns, conducted code reviews, and worked directly with clients to align technical delivery with requirements.

My earlier full-stack work included microservice integrations, WordPress development, Linux mail services, analytics, search, filtering, and content-management workflows. I also developed more than 10 Flash games and converted them into mobile apps.

I enjoy solving difficult system-integration problems with reliable backend architecture, optimized SQL, and practical frontend controls.
