Do you remember that scene in Pulp Fiction when Jules and Vincent are in a car covered in blood with a dead body in the backset, absolutely freaking out, and they have to call Mr. Wolf?
He steps in, gets to the job site in record time, takes control of the situation and cleans up the mess that nobody else had any idea how to deal with.
Well on Upwork, I am that guy.
Except instead of cleaning up crime scenes, I help companies navigate high-stakes, complex technical challenges across the modern web.
Why clients choose to work with me:
- ๐ญ๐ฒ๐ฟ๐ผ ๐ต๐ฎ๐ป๐ฑ-๐ต๐ผ๐น๐ฑ๐ถ๐ป๐ด: I excel in ambiguous, complex situations. Hand me a messy problem, and Iโll return with an intuitive, production-ready solution.
- ๐ก๐ผ "๐ง๐ฒ๐ฐ๐ต-๐ฆ๐ฝ๐ฒ๐ฎ๐ธ": As an intuitive logician, I value clarity and precision. I use short video walkthroughs to summarize bugs, progress, and outline technical choices so you can understand situations and make decisions fast.
- ๐๐ด๐ป๐ผ๐๐๐ถ๐ฐ: I am cloud and framework agnostic. Having shipped production code in at least four distinct programming languages, worked in both AWS and GCloud, I adapt quickly to new stacks as I have a solid background in the fundamentals of web engineering.

Above all, Iโm a problem solver who thinks in systems. Languages and frameworks are just tools, and tools can be figured out quickly. What matters most is having the engineering intuition to step into a complex, ambiguous situation and design a clean, logical solution that aligns with business goals.
Drop me a line, and letโs see if I'm a good fit.

If your Shopify, HubSpot CMS, or WordPress site is slow, hard to update, buggy, or too dependent on developers, I can help you fix the real problem without adding more technical mess.
I work with agencies, ecommerce brands, and marketing teams that need reliable development beyond basic content edits: clean implementation, troubleshooting, performance improvements, reusable modules, flexible templates, and CMS/ecommerce structures their team can actually manage.
I bring 13+ years of hands-on web development experience and 8,800+ hours on Upwork across Shopify, HubSpot CMS, WordPress, and WooCommerce projects for US-based agencies and ecommerce brands.
Common projects I can help with:
- Shopify theme improvements, custom sections, templates, product page updates, metafields/metaobjects, and product-related functionality
- HubSpot CMS modules, HubL/HubDB components, landing pages, blog/resource templates, and dynamic front-end builds
- WordPress and WooCommerce fixes, custom implementation, reusable content components, and theme/plugin adjustments
- Performance improvements, Core Web Vitals cleanup, image/media optimization, and front-end technical fixes
- Technical SEO implementation across templates, content structure, metadata, schema, and internal linking support
- Debugging complex layout, responsive, UI, JavaScript, Liquid, HubL, PHP, and CSS issues
- Ongoing support for launches, site updates, production fixes, and improvements inside existing codebases
Iโm used to working inside active client projects, existing codebases, and fast-moving environments where quality, clarity, and reliability matter. I can jump into a project, identify what needs to be fixed or improved, and move it forward efficiently.
I also use AI-assisted workflows where appropriate to speed up research, troubleshooting, and implementation, while keeping quality control and technical decisions grounded in hands-on development experience.
