WordPress & Elementor Designer | Fast, Responsive, Websites That Convert. Most business owners lose customers every day because their website doesn't convert.
I build WordPress and Elementor sites that fix that fast loading, professional, and built to turn visitors into paying customers from day one.
A client came to me after getting scammed.
He'd paid another developer good money for a WordPress site with a booking system and payment gateway. It didn't work. Visitors couldn't book, payments failed, and he was losing foreign tourists who wanted to visit Bali, Lombok, and Sumba. We rebuilt everything clean design, proper Amelia booking system, working payment gateway. His revenue went up 20%.
That's what a properly built WordPress site does.
More results from clients outside Upwork:
- A batik sarong export business from a small town in Java targeting the US market. Built a professional site that gave them credibility with international buyers. Revenue up 15โ20%. Now shipping container loads to America.
- A dive travel specialist targeting foreign tourists in Bali. Built a focused landing page. Conversions up 10โ20%. Foreign clients now trust and book immediately upon landing on the site.
- A director and videographer who needed a portfolio site to close more clients. Built it. Now 9 out of 10 outreach leads close at high value projects.
What I build:
- Business websites and landing pages built for conversion
- Booking-ready websites with online payment integration
- WooCommerce stores with payment gateway setup
- Multilingual websites for businesses targeting international audiences
- Website redesigns that modernize without breaking what works
- Bug fixes: broken layouts, slow pages, plugin conflicts, contact form issues
How I build it:
Every site is built so your customers can find it, trust it, and take action without you chasing every inquiry manually.
- Elementor Pro for pixel perfect, responsive layouts
- Amelia Booking for 24/7 self booking and deposit collection
- WooCommerce + Payment Gateway for automatic payments
- WPML/TranslatePress for multilingual support
- N8N Automation for followups that run without you
- RankMath SEO so your site gets found on Google
I work best with business owners who have a clear goal more bookings, more leads, more sales. I build toward that goal, not just deliver a pretty page.
Unlimited revisions until you're fully satisfied.

I'm the founder of a software agency that delivers custom software solutions for startups, SMEs, and enterprise clients. In addition to handling projects personally as a Full Stack Software Engineer, I also have the experience and resources to manage larger, more complex projects that require scalable architecture, long-term maintenance, and coordinated development efforts.
With over six years of experience, I've built ERP systems, custom web applications, automation tools, and AI-powered solutions that solve real business problems.
I enjoy working across the entire development process, from understanding business requirements and designing system architecture to deployment and long-term maintenance. My goal is always to build software that is reliable, scalable, and easy to maintain.
I can help with:

Beyond client work, I've founded technology companies, led software engineering teams, built products used by hundreds of users, and currently serve as an Adjunct Lecturer teaching Microservices, Software Testing, Cloud Computing, Game Development, and Web Development.
I believe good software starts with understanding the problem. If you need someone who can communicate clearly, think beyond just the code, and deliver production-ready solutions, I'd love to discuss your project.

Iโm a Backend Developer and Web Hosting Administrator with 8+ years of experience helping businesses fix broken web applications, integrate Stripe payments, and maintain reliable server environments.
Whether you need a Stripe webhook debugged, a VPS hosting setup optimized, or a backend API repaired, I specialize in resolving high-priority blockers. Most clients hire me when an application stops working, server configuration limits cause deployment errors, or they need a reliable expert for live remote diagnostics.
What I Can Help You With:
Hosting & Server Administration: Web hosting setups, VPS/Linux maintenance, cPanel/WHM management, and production system auditing.
Integrations & Payments: Fixing failing Stripe webhooks, building custom REST API workflows, and troubleshooting third-party data streams.
Backend Development: Deep expertise in repairing PHP, Laravel, and Ruby on Rails environments.
Web Server & Domain: Nginx/Apache reverse proxies, Cloudflare configurations, complex DNS routing, and SSL deployments.
Runtime & Database Tweaks: Adjusting server limits (PHP timeouts, memory limits) and optimizing slow MySQL/PostgreSQL queries.
Common Problems I Solve:
API integration runtime errors and missing Stripe payment data.
Server-level runtime limits, request drops, and production downtime.
Broken web server configurations, bad redirects, and failed SSL handshakes.
Backend functionality breaking after application updates or server migrations.
Technical Stack:
Infrastructure: Web Hosting, VPS, Linux, Nginx, Apache, Cloudflare, DNS.
Languages & Frameworks: PHP, Laravel, Ruby on Rails.
Integrations: Stripe Billing, REST APIs, Webhook Architecture.
Databases: MySQL, PostgreSQL.
How I Work:
I focus on identifying the root cause via system error logs before implementing changes. You can simply queue up the API keys or server access, and I will safely implement and test the fix asynchronously without interrupting your live traffic. I am also fully comfortable jumping onto live remote diagnostic sessions to resolve emergency blockers.
