Senior Software Engineer with 9+ years of experience building scalable web applications, WordPress products, eCommerce systems, and backend-heavy platforms across PHP, JavaScript, Node.js, and React.

I enjoy taking ownership of difficult products, reviving stalled projects, and turning complex requirements into production-ready systems that teams can actually maintain.

I work at the intersection of product engineering, backend architecture, and practical delivery.

Over the years, I’ve worked across:

• Large WordPress plugins and theme ecosystems
• Custom billing and licensing systems
• eCommerce platforms and payment integrations
• Distributed monitoring and automation systems
• React-based dashboards and admin experiences
• VPS/server management, deployment pipelines, and production debugging

I’m especially comfortable stepping into messy or high-pressure situations, improving architecture, unblocking delivery, and helping teams ship with confidence.

• Build extensible plugin and application architectures
• Design backend systems, APIs, and licensing flows
• Improve performance, maintainability, and developer experience
• Lead implementation on products that need ownership and direction
• Bridge frontend, backend, and infrastructure concerns when a product needs end-to-end thinking

At Kodezen, I helped lead the development of a digital-product-focused eCommerce solution for WordPress.

Highlights:

• Helped recover a stalled 2.5-year project and deliver a production-ready MVP within 4 months
• Designed a scalable licensing system with activation, validation, deactivation, and analytics APIs
• Built a reusable PHP SDK for WordPress products to integrate with licensing and telemetry flows
• Contributed to modular plugin architecture, subscriptions, installment payments, bundled products, and analytics integrations

Built and owned an end-to-end monitoring platform featuring:

• Node.js workers for large-scale uptime and endpoint monitoring
• Python-based agents for distributed server monitoring
• Real-time alerts and operational visibility
• React-based status and reporting interfaces

Across different roles, I’ve also worked on:

• WooCommerce-based internal billing systems
• Multi-PayPal payment routing extensions
• Location-aware service platforms using Google Maps and geolocation APIs
• Web3 and crypto payment integrations
• Custom WordPress importers, theme systems, and admin tools
