Hi,
It's Syed. Thank you for reviewing our profile and considering me for your project needs.
I am a PRO PHP Coder with over a decade of experience building websites, fixing issues, and fixing errors with clients' websites.
Now, my core expertise is in building websites and NFT websites. However, I have also helped clients clean up malware from hacked websites. Or I am Improving the speed of the website. Clients often have updated wordpress or the theme, and their website gets messed up, so I help them. Sometimes, they upgrade the plugins, and then there is an internal server or 404 error or 503 error, so I help them with that or fix database errors.
The plugins and themes/builders that I have worked with are ;
1—WooCommerce: If you have an Error with WooCommerce or want to customize it or the checkout page, I am your guy. I deeply understand WooCommerce issues and code and can help you fix those quickly.
2- Divi Builder / WpBakery / Elementor Builder:
I have built many websites using Divi Builder and Elementor Builder, and some using WP Bakery Builder. So, I know how all the functionality of these builders works and can help clients fix issues reasonably quickly.
3- Creating Custom Wordpress Theme from PSD FIGMA or NFT Designs
I can perfectly code PSD to Wordpress or FIGMA to Wordpress theme. You can share the mockups, and I can help you build a fully dynamic and responsive WordPress theme from them.
I can build Custom Themes or Private Apps for Shopify and have helped clients create Shopify stores. Let me know if your Shopify website is buggy, and I'll help you fix the issue.
I also provide monthly website maintenance support to clients who need it. Sometimes, you don't want to worry about upgrades or deal with website security, so clients hire me for monthly website maintenance service. I help them improve the security of their website so it's safe against hack attacks or malware attacks. I also keep the website speed optimized so the core vitals are good.
Lastly, this is not a commercial service often given to select clients. I am a very passionate Video Editor. I love editing videos, primarily in Adobe Premiere and Adobe After Effects. So, if you want to edit your YouTube videos, you can share your ideas with me, and if that is something I could help you with, we can discuss that video editing job further.
I look forward to working with you and providing you with reliable, quality tech support so that you can relax and focus on what you do best.

I'm a senior .NET developer with over 12 years on Upwork, specialising in Windows desktop applications, legacy system work, and business integrations across the Microsoft stack.
My background is broad, but where I'm most useful is on the harder projects — undocumented codebases, legacy migrations, ERP integrations, and end-to-end delivery of complex Windows software. These are the kinds of projects I've built a reputation around.
A recent example: I designed and built a full Windows Assistant platform using WPF — combining video capture, SharePoint content management with a Windows Explorer-style interface, a locally cached SQLite database with a background sync service, and a Web API built on a clean services/infrastructure architecture over Entity Framework Core and SQL Server. The system included SignalR real-time notifications, JWT authentication, and integrations with Vimeo, Twilio, SmileBack and others, alongside a complete MVC admin portal.
What I work on:
Legacy systems — VB6, Visual FoxPro, VB.NET, WinForms, WPF. I regularly take on codebases other developers decline, and I'm comfortable working in undocumented or inherited code.
ERP and business integrations — SAP, SAGE, MYOB, SQL Server, Oracle, Shopify, DocuSign, Amazon API and more. I've worked across insurance, logistics, and enterprise clients and understand how business-critical systems need to behave.
I ask the right questions before I start, flag issues early, and deliver on time. Clients tend to come back for that as much as the technical work.
Tech I work with:
WPF · WinForms · C# · .NET / ASP.NET · WCF · Entity Framework Core · SQL Server · Oracle · SQLite · SignalR · JWT · REST APIs · SharePoint · MS Office Add-ins · SAP · SAGE · MYOB · VB6 · VB.NET · Visual FoxPro · Shopify · DocuSign · Amazon API · Vimeo · Twilio · MVC
