I’m 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.

Stuck with a legacy .NET or PHP system nobody wants to touch, a third-party integration that keeps breaking, or a mobile app that needs to ship without slowing down your web platform? I build and maintain production systems that hold up under real business use - enterprise software, web platforms, and mobile apps that don't fall over as they grow.
Hi, I'm Yusrizal 👋 Senior Full-Stack Developer with 18+ years of experience across EdTech, government, energy, and healthcare. Top Rated on Upwork, 100% Job Success, 90+ companies served.
I've solved problems like:
- Cut redundant authentication requests ~60% by adding Redis caching to a production auth service for Pertamina, Indonesia's national energy company
- Built a national partnership-data platform for Indonesia's Ministry of Education to manage vocational-education partnerships
- Automated a PHP microservice that parses real-time XML feeds to keep product pricing and discounts in sync across systems
- Integrated a government digital-signature API (PERURI) so a state polytechnic could issue legally valid digital diplomas
- Replaced fingerprint check-in with a React Native attendance app for remote staff
- Founded and led an EdTech startup (school management/LMS) that won a national tech-incubation award
What I can help you with:
- Enterprise & Backend Systems → C#/.NET (Core, Framework, ASP.NET) + SQL Server for business-critical systems
- Web Platforms & APIs → PHP (Laravel, Yii2, CodeIgniter) + MySQL/PostgreSQL, REST API design and integration
- Mobile Apps → React Native + Firebase/Expo, cross-platform iOS/Android
- Payments & Integrations → Midtrans, PayPal, CryptAPI, government APIs, XML feeds, IoT data
- Performance & Reliability → caching (Redis), query/API optimization, cutting redundant load
- Cloud & Deployment → AWS (S3, EC2, Amplify), DigitalOcean, Git
Tech I use (when it actually fits the job):
- Backend: C# / .NET (Core, Framework, ASP.NET), PHP (Laravel, Yii2, CodeIgniter), Node.js
- Frontend/Mobile: React, React Native, Expo, Firebase
- Database & Caching: SQL Server, PostgreSQL, MySQL, NoSQL, Redis
- Integrations: REST APIs, Midtrans, PayPal, CryptAPI, PERURI, XML, IoT
- Infra: Microsoft Azure, AWS (S3, EC2, Amplify), DigitalOcean, Git
- AI-assisted workflow: Claude, GitHub Copilot, ChatGPT, DeepSeek
- Collaboration: Jira, Trello, Agile
How I work:
- I focus on delivering working systems, not just code
- Comfortable owning a project end-to-end (requirements → architecture → deployment) or slotting into an existing team
- AI-assisted development helps me move faster - every change still gets reviewed and tested the same as it would without it
- I pick the simplest stack that will actually hold up in production, not the trendiest one
- 18+ years means I've led teams (as a startup CEO and as a platform lead) and worked solo - I adapt to what the project needs
I take on projects I'm confident I can deliver well. If you need .NET, PHP, or React Native work - building something new, or fixing and scaling an existing system — send me a message and let's talk specifics. 🚀
