Check the logic of the service for clothing cutting.

Good day!
The project is right in my area — I am not just a coder, but a person from production who understands the essence, not just writing code (as you mentioned in the update).
I develop and manage a custom ERP for printing and manufacturing: it includes material cutting calculations, inventory management, distribution across sections, and total inventory recalculation after acceptance. I understand the logic of "model → category → warehouse synchronization → actual stock → cutting → distribution to workshops → acceptance → recalculation" not theoretically, but because I built such a system myself.
I have also dealt directly with fabric cutting: I participated in a project for making tablecloths, where there was its own logic for cutting the fabric — calculations based on product dimensions and optimization of leftovers. So, I understand the specifics of sewing/textile production.
I am familiar with LP CRM, having worked with it before — so I can set up the integration through a proxy without any hassle.
Your stack works for me: PHP/JS every day, Vanilla JS + REST API + Node.js proxy — no problems.
Here’s how I see the work:
1. Refactoring — remove dead functions, duplicates, conflicts between old/new logic, and duplicate IDs.
2. Check all connections between sections to ensure the 8 modules work synchronously without reloading.
… 3. Connect real integration with LP CRM through a proxy, ensuring correct inventory accounting.
4. Run the final test — all 10 steps on a live account + a short report on what I found and fixed.
I am ready to call and discuss the details regarding the inventory in LP CRM together. I work step by step, verifying each stage.
I will clarify the timeline and final cost after I look at the file and the scope of integration — but overall, the task is clear. My portfolio (e-commerce project on PHP/JS) is in my profile.

Hello!

I carefully read the description — the task is clear, structured, and specific. This is exactly the type of work where accuracy is more important than speed.

Here’s how I see the solution for each block:

Block 1 — Refactoring: I will go through the entire file, remove dead functions and duplicates, resolve conflicts between the old and new logic, and fix duplicated IDs in the HTML. The code will become clean and readable.

Block 2 — Logic of connections: I will check all four critical connections between the 8 sections. I will separately verify the formula for calculating cuts with distribution by colors, sizes, and workshops — I will ensure that the proportions and rounding work correctly.
…
Block 3 — LP CRM API: I will add two new routes on the proxy server (product categories + products with remaining stock by category). I will check the existing synchronization route. I will test on a real account — I will go through all 10 final steps.

Stack Vanilla JS + Node.js — my stack. I can start today.

If you have any questions — write to me, and I will clarify the details before starting.

Hello, I am an individual developer with over 4 years of experience, working officially through a sole proprietorship. I will personally dive into the architecture of your application: I will remove dead code, fix duplicate IDs, and implement the logic of connections between sections using the Observer pattern or through a global state to avoid reloads. I will set up API routes on your Node.js proxy and personally test the entire cycle from key to handover. My portfolio: 3magency.co, Behance.

Welcome, we are a small team that has been creating digital products for over 4 years. We will approach the task comprehensively: we will conduct refactoring, set up routes on Render, and perform stress tests for synchronization. We will understand the logic of your production so that automation in "KroiLab" becomes a reliable tool rather than a source of errors. Our results: freshagro.com.ua, farfieworldwide.com, rivnekolo.com.

Good day, my colleague and I have been specializing in production automation and CRM integration (specifically LP CRM) for over 4 years. We offer not just to clean the code, but to optimize data exchange to minimize the number of requests to the proxy. We will check the logic of distribution across workshops according to their capacity and ensure the correctness of localStorage when working with multiple models. Please take a look at our case studies: drkukharevich.rivne.ua, crave-agency.com.ua, jk-solution.com.ua.

Hello, my partner and I (full-stack developers) are ready to take on "KroyLab" with over 4 years of combined experience. I will focus on Block 2 (mathematics of cutting calculations, size proportions, and synchronization of 8 sections), while my partner will conduct a complete "disinfection" of the code and set up a proxy on Node.js. We will delve into each formula to ensure that the inventory in the LP CRM and the application is identical. Our joint projects include: hyperfi.tech, espressolab.com.ua, hudi.com.ua.

Hello,

I read the technical specifications carefully — there are three clear blocks: cleaning the vanilla JS file, fixing four connections between sections, and expanding the Node.js proxy with two routes in LP CRM (categories + products with stock).

Approach to work:
1. First, I will go through the file, draw a graph of the connections between sections, and mark dead code / duplicates — I will send a brief "what I found" before I start refactoring.
2. I will fix the connections one by one, using explicit events / observer, without reloading. I will leave localStorage as is, but I will bring the scheme to a single format.
3. Proxy on Render — I will add /categories and /products?category_id with passing the Bearer token from LP CRM and caching for ~30 seconds to avoid hitting the rate limit.
4. I will run a final 10-step test on a real account, with a brief report in Markdown.

Welcome! Our team with 4 years of experience in system programming and developing complex algorithms is ready to conduct a thorough audit and check the logic of your cutting service. We specialize in working with C/C++, C#, Python, and TypeScript, which allows us to deeply understand the internal architecture of computational scripts, mathematical models of figure layouts, and geometric algorithms.
We will perform rigorous testing of the service, analyze the code for logical errors, verify the correctness of input parameter processing, and identify bottlenecks that may lead to failures or suboptimal calculation results.
We will provide a detailed technical report with identified issues and clear recommendations for their resolution.

Hello! I have experience with CRM integrations, refactoring complex JS projects, and building logic for warehouse/manufacturing accounting. I can not only "fix the code" but fully immerse myself in the business logic of KroyLab, check all connections between modules, calculation formulas, and the correctness of working with LP CRM.

I can also finish the Node.js proxy, check API routes, synchronization of balances, categories, and products, as well as conduct a complete final test of all scenarios without reloading.

Examples of work: apple-family.com.ua/uk 3magency.co

I am ready to thoroughly review the code and the technical specifications and provide an accurate estimate of timelines and budget.

The task is clear: refactoring a vanilla JS file, fixing synchronization between sections, and creating two new routes on a Node.js proxy with testing on a real LP CRM account.

I will complete all three blocks: clean up dead code and duplicates, check and fix four connections + the cutting formula, add routes for categories and products with stock, and run the final 10 steps. I will deliver a clean file, an updated proxy, and a report. Deadline — 2 days, 4000 UAH.

Can you provide access to the repository and the test LP CRM account?
