Francisco Silva.

11+

Years Experience

Based in Portugal

Hi, I'm Francisco Silva. Your Long-Term WordPress Engineering Partner.

I'm a senior WordPress engineer with over 11 years of hands-on experience customizing, building, and deploying WordPress solutions. I work directly with business owners who need a solid digital presence, and as a trusted development partner for digital and marketing agencies — often as a white-label extension of their team.

From custom themes and plugins to third-party integrations, payment gateways, and performance-oriented builds — I focus on security, scalability, and long-term maintainability. My process starts with a clear alignment on goals, scope, and priorities, followed by a phased execution plan with short review cycles and incremental deliveries. No unnecessary complexity, no plugin bloat — just clean code built to last.

I'm not just another developer. I contribute to project direction, provide UX/UI feedback, and communicate directly with stakeholders. Whether you're launching your first website or you're an agency scaling your delivery capacity — think of me as a technical partner, not just an executor.

Reliable

Clear communication and on-time delivery.

Autonomous

Self-driven, proactive, remote-ready.

Strategic

UX/UI feedback and project guidance.

Long-term

Sustainable, maintainable code.

Let's Talk.
