Clinical Skills Institute is seeking an expert-level Wix performance specialist to optimize the speed, Core Web Vitals, tracking configuration, and mobile user experience of our high-traffic website:
https://www.clinicalskillsinstitute.com
This is not a general website-design, SEO-content, or image-compression project. We need someone with advanced experience in Wix Editor, Velo, Google Tag Manager, Google Ads conversion tracking, GA4, TikTok Pixel, Meta Pixel, third-party applications, and Core Web Vitals.

Our preliminary technical audit identified:
- Approximately 412 network requests on the homepage
- Approximately 193 JavaScript requests
- Approximately 4.48 MB of transferred JavaScript
- Duplicate Google Tag Manager loading
- Multiple Google Ads and Google Analytics loaders
- Two separate TikTok pixels
- A suspended AnyTrack installation
- An expired accessiBe installation that continues loading scripts
- An unidentified script producing a Wix 404 error

- Outdated Velo code attempting to open a deleted popup
- An immediate full-screen promotional form on mobile
- Approximately 46 homepage sections and 3,500 DOM elements
- Heavy Wix Form, FAQ, chat, gallery, video and third-party components
Project Scope
The selected specialist will:
1. Conduct a Complete Performance Audit

2. Audit and Correct Analytics Tracking
- Create a complete map of all installed tracking tools and conversion IDs
- Identify why Google Tag Manager container GTM-M8QH47F7 loads more than once

- GT-PHXRXKWT
- GTM-M8QH47F7
- Investigate two active TikTok pixels and retain only the correct implementation
- Correct the invalid TikTok event
- Review Meta Pixel, Microsoft Clarity, Cometly and other attribution tools
- Remove broken, abandoned or duplicate tracking scripts
- Use GTM Preview, Google Tag Assistant, GA4 DebugView and advertising-platform event tools to validate the final configuration
No tracking tag may be removed without first identifying its purpose and verifying that it is not required for advertising attribution or enrollment conversion reporting.
3. Remove Broken and Unnecessary Code
- Remove the suspended AnyTrack implementation
- Remove or correctly reactivate the expired accessiBe integration
- Identify and remove the script generating the Wix 404C error
- Audit all Wix Custom Code entries

- Wix Pricing Plans
- Wix Members
- Wix Chat
- Wix Blog
- Wix Video
- Wix FAQ

- Replace heavy galleries, sliders, videos or app widgets with lighter alternatives where appropriate

What Employers Look For
The qualifications that appear most often in full stack developer jobs.
- Proficiency in at least one frontend framework such as React, Angular, or Vue
- Backend experience with Node.js, Python, Java, or a comparable server-side language

- Familiarity with RESTful and GraphQL API design and integration
- Experience with version control using Git and collaborative development workflows
- Understanding of cloud platforms such as AWS, Azure, or Google Cloud for deployment
Tips for Your Full Stack Developer Job Search
Tailor your stack to each listing
Full stack job descriptions are rarely identical. Before you apply, swap the order of your listed technologies so the stack the employer actually uses appears first. Recruiters scan for their exact toolchain, not a generic list of languages you know.
Show projects end to end
Employers want proof you can own both layers. Your portfolio should include at least one project where you built the database schema, the API, and the frontend yourself. Label it clearly so hiring managers don't have to guess which parts you wrote.
Apply early to roles that fit
Migrate Mate lists full stack developer openings from across the United States in one place, so you can find roles that match and apply directly to each listing.
Filter by the framework first
Searching by job title alone mixes Python Django shops with React TypeScript teams. Search for the specific framework you want to work in alongside the title to surface openings where your depth is actually relevant and your application will be competitive.
Prepare a system design answer for your current scale
Full stack interviews often include a system design question, even for mid-level roles. Practice designing a feature you have actually shipped, so you can talk through real constraints like database indexing decisions or caching tradeoffs instead of a textbook diagram.
Negotiate the whole offer, not just base pay
Full stack roles frequently include equity, remote stipends, or professional development budgets that vary widely between companies. Ask for the full compensation breakdown before accepting, and confirm which components vest or expire if the role changes.
Full Stack Developer Jobs: Frequently Asked Questions
Which companies are hiring the most full stack developers?
The companies hiring the most full stack developers right now include Infosys, Citi, and Booz Allen Hamilton, with the largest share of openings in Virginia, Texas, and California, based on current listings on Migrate Mate as of August 2026. Demand is broadly distributed across industries, so strong candidates have options well beyond the usual tech hubs.
How many full stack developer jobs are remote?
About 54% of full stack developer openings are fully remote or hybrid as of August 2026, making it one of the more flexible roles in software engineering. Positions focused on frontend-heavy or API-layer work tend to go fully remote most often, while roles requiring close coordination with on-site infrastructure teams are more likely to be hybrid.
How do you become a full stack developer?
Start by getting comfortable with one frontend framework and one backend language before trying to learn everything at once. Build complete projects that connect a database to a server to a browser interface. Learn the basics of deployment so your work is publicly accessible. Apply for junior or associate roles once you can point to shipped projects, and deepen your skills on the job from there.
Can you get hired as a full stack developer without much experience?
Yes, but your portfolio has to do the work your resume cannot. Build two or three projects that each demonstrate the full stack: data persistence, server logic, and a working UI. Contributing to open-source repositories and completing a code-review cycle with real feedback also signals readiness to employers who might otherwise pass on a thin work history.
What does the full stack developer interview process look like?
Most full stack interviews run through a recruiter screen, a take-home or timed coding assessment, a technical interview covering algorithms and data structures, and a system design round where you walk through building a feature. Some companies add a frontend-specific challenge. The whole process typically moves across several rounds over a few weeks, ending with a conversation about team fit.
Where can I find and apply to full stack developer jobs?
You can find and apply to full stack developer jobs on Migrate Mate, which lists current openings from across the United States. Search the listings to find roles that match your stack and experience level, then apply directly to each one that fits. There is no intermediary step between finding a role and submitting your application.
