You will get Loan Payments Calculator - Slider with Real Time Payment Calculation
Project details
You will get a loan calculator made with NOUISLIDER to get the loan amount selected by the user with real-time payments for 12,24,36,48, and 60-month financing. The years can easily be adjusted to have different time lengths.
This calculator is just one example of the custom calculator projects that I have done. In my portfolio I have a long littany of custom applications I built, some even integrating the simplicity of Google Sheets as a database to integrate into web apps, others integrating with APIs, Zapier, email, and other systems.
Since my start in '97, I have been building custom applications and intermingling my work in marketing to create systems for building out systems and workflow for hyper-personalized assets which marketers today need in order to get the conversions they desire.
Since 2003, I have published many applications for the marketing arena, some you may even know of by name, some of which are still working to maintain the top page ranks in search for several older clients of mine.
If you need a custom app, heck, maybe even some copywriting and graphic design work too, it's much easier to work with one person instead of coordinating with several.

Add code to push data to Zapier/Brevo
John's work was excellent, and he was very responsive. Unfortunately, something changed when I paused the contract for a couple of weeks, which is my standard practice when I cannot focus on a project. When I restarted the contract, he did not respond. I allowed ample time and made several attempts to contact him. It was out of character, and I became concerned about his well-being, thinking he might have had a mishap. I still wonder why he refused to reply rather than just letting me know he didn't wish to continue, and is the reason for my less-than-5-star rating.

About John
Conversion Audits & Behavioral Analytics | Landing Pages & Tracking
Camden, United States - 10:52 pm local time
Results from that approach:
• Reworked one landing page in about an hour — resequenced the headline, reviews, and layout — conversions rose roughly 1000%
• Full rewrite for an insurance company: ~600% lift
• Built an automation system that turned 90 days of staff work into an overnight process
• $200K+ earned here across 460+ jobs — clients tag me most for Reliable (106), Clear Communicator (101), Committed to Quality (100)
What I do:
• CONVERSION AUDITS — "opinions on paper." A written diagnosis of where your funnel bleeds: message match, mobile experience, trust signals, tracking integrity, traffic quality. Prioritized fixes your developer can execute without interpretation, plus a Loom walkthrough.
• LANDING PAGES — design, code, and direct-response copy from one person (certified in direct-response copywriting; Frank Kern's Inner Circle).
• TRACKING & DATA PLUMBING — GA4, Tag Manager, webhooks, Zapier/Make, HubSpot API, CRM pipelines. A client's words: "John helped me untangle an overly complicated process between my website and CRM that wasn't working properly."
• PAGE SPEED — because a 14-second mobile load kills the sale before your headline gets a chance.
The difference: I build my own marketing software — behavioral analytics that measures whether visitors actually READ each section of a page, and lead-quality scoring that flags the junk clicks quietly burning ad budgets. When you hire me, you get the operator and the toolmaker.
I price defined outcomes at flat rates, report in plain English, and move fast.
Send me your URL and I'll tell you the first two things I'd fix — before you spend a dollar.
