Hello everyone. I am looking for a specialist who can help solve the problem with the React source files. The issue is that they are missing. Therefore, a new repository needs to be created, extract as much as possible from DevTools/source maps, and then restore the project. I will provide details to the candidates. I look forward to your responses.

The site is built on the Next.js framework (based on React). All points in the technical specification need to be completed. The technical specification is attached in the file. I look forward to your proposals.

there is a website https://perfect-okna.com.ua/ main problems: SPEED ANALYSIS (Performance) Key issues (typical for such websites): · Large unoptimized images (JPEG/PNG without compression, no WebP). · Lack of lazy loading for images in the catalog. · Non-minified CSS/JS, many unnecessary libraries connected. · No caching at the browser level, CDN not used. · Server does not provide compression (gzip/brotli). · HTTP/2 not used. Checklist "Speed": · Compress all images, convert to WebP and add fallback. · Set up lazy loading for images (loading="lazy"). · Minify HTML, CSS, JS. Combine files where appropriate. · Enable Gzip/Brotli on the server. · Set cache headers (Cache-Control, Expires) for static content. · Connect CDN (Cloudflare for free). · Remove unnecessary plugins/scripts (especially if WordPress). · Use asynchronous loading for non-critical scripts (async/defer). On the homepage, there is often no clear structure "who we are - what we offer - why choose us - how to order". · The window constructor (if available) can be confusing, without hints, the final price is not visible immediately. · On mobile devices, the menu may shift, the calculator is not adapted for fingers. · Feedback forms are long, without phone masking, without validation. · No "quick actions": call with one click, messengers, chat. · Lack of "breadcrumbs" on internal pages. · Create a mobile version without horizontal scrolling, buttons no less than 48x48 px. · On the homepage, add a price calculator "in 3 clicks" immediately. · In the header – clickable phone number (tel:), messengers (Viber/Telegram) with icons. · Forms: only name + phone + "comment" field (optional). Phone mask. · Add a floating button "Quick Order / Calculate Cost" on mobile. · On product cards – "Buy in 1 click" button (opens a mini-form). · Add "breadcrumbs", improve navigation through sections. · Check text contrast, font size (at least 14 px on mobile). · No urgent offer (time-limited promotions). · Insufficient social proof (reviews, video reviews, number of completed works). · It is not explained that the price is "turnkey" (installation, delivery, dismantling). · No CTA (call to action) on every screen. Add a "counter" – how many clients have already chosen, how many windows installed. · Video reviews from real clients (short, 30–60 sec). · Block "Calculate in 30 seconds" right on the first screen. · Show the "turnkey" price: window + installation + delivery, with a transparent breakdown. · Promotions with a timer: "15% discount for orders by the end of the week". · Popup window with an offer for a free measurement when the user tries to close the tab. What to do: · Interactive 3D window configurator (color change, opening, glazing) – more on this later. · Mini-game or test: "Which window is suitable for your apartment?" · Cases: photos "before/after" in real interiors. · Guides: "How to choose windows for a noisy street", "Energy saving: which glazing to choose". · Heating savings calculator after window replacement. Urgent (Critical) 1. Mobile adaptation of the entire site, especially the constructor and cart. 2. Speed up loading: image compression, caching, CDN. 3. Quick order button (One Click Buy) on all product cards. Popup chat with the ability to leave a message in Viber/Telegram. 5. Valid HTTPS and redirect from HTTP → HTTPS for all pages. 6. Microdata Schema.org (Organization, Product, BreadcrumbList, Review). Important (High) 1. Update the homepage: add USP, promotions, videos, quick calculator. 2. "Promotions" page with a timer, updated monthly. 3. Callback form – simple, with a mask and automatic city code substitution. 4. CRM integration (e.g., amoCRM / Bitrix24) for automatic lead capture. 5. Add online payment (LiqPay, WayForPay) at least for prepayment for measurement. 6. SEO URL structure: /produkciya/plastikovi-vikna/, not /?page_id=123. Desired (Medium) 1. Expand the blog with articles for key queries (5 articles at once). 2. Interactive constructor with 3D view (separate block below). 3. Product filter by characteristics (size, profile, color, price). 4. Personal client cabinet, where you can see the order status. 5. Generation of PDF commercial proposal directly on the site. HOW TO IMPROVE THE CONFIGURATOR (Window Configurator) If it is currently a regular form with dropdown lists – this is outdated. A modern 3D configurator is needed: Mandatory features: · Step-by-step wizard: 1) room selection, 2) dimensions, 3) number of sashes, 4) color, 5) glazing, 6) fittings, 7) mosquito net. · Instant price recalculation at each step (AJAX). · 3D visualization (Three.js or ready js framework). · Saving the selected configuration in PDF (server-side generation) and sending to email. · Button "Send calculation to manager" – and a card with all parameters flies to CRM. · Ability to share a link to your configuration (for example, to send to husband/wife). · Full adaptation for touch gestures (swipe to rotate the 3D model on the phone) Price is negotiable!
