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
