I have full permission from the current site owner to reproduce their website. The live site is hosted on GoDaddy, but I’m not certain which CMS or framework was used, so the first step will be to identify the stack (WordPress, Wix, custom HTML, or otherwise) and replicate it faithfully on my new hosting environment. Once the layout, pages, and functionality are mirrored, I need two branding tweaks: • Replace every instance of the existing business name with my new one and update all phone, email, and address information. • Swap in a fresh logo and ensure all favicon or social preview images reflect the new brand. Everything else—structure, imagery, copy, and navigation—should remain exactly as on the original site so that visitors enjoy the s...

I’m seeking an experienced developer to help turn my concept into working software. The project is firmly in the “Software development” space, though I’m still open on whether the final product will be web-based, mobile, or a desktop build.

Two bite-sized, professionally-toned promotional videos have to go live every single day—morning and afternoon—without fail. Once created, each clip must be natively published to Instagram, Facebook, Twitter, TikTok and YouTube so our message stays consistent yet platform-appropriate seven days a week. Beyond social video, the same steady rhythm is expected on the website. On-page tweaks, technical fixes, speed improvements, backlink outreach and all other white-hat off-page tactics should run in parallel, keeping rankings moving upward while the content engine hums. To support that effort, I also need one well-researched blog article per week that ties into the video themes and reinforces our SEO strategy. Core deliverables • 2 short promotional videos daily (14 ...
... and occasional animation or rendering tweaks. You should be comfortable taking loose sketches or reference images and turning them into clean, well-organized .blend files that are production-ready and easy to iterate on. Strong topology, sensible naming conventions, and an eye for detail are essential; efficiency in Eevee and Cycles is a big plus. Communication matters just as much as technical skill, so I’ll expect regular progress updates, quick turnaround on feedback, and clear explanations of any creative or optimisation choices you make. If you have a portfolio that shows a breadth of Blender work—be it game assets, architectural scenes, or cinematic shots—please include it so I can gauge your range. I’m ready to start as soon as I find the ...

...This system requires advanced system-level engineering, multi-core CPU architecture control, shared memory communication, and real-time observability dashboard. The focus of this project is minimizing latency between signal generation and order execution while maintaining regulatory compliance (Order-to-Trade Ratio constraints). The developer must understand low-level performance optimization, concurrency architecture, and Linux system behavior. Core Technical Requirements Python Version (Mandatory) The engine must use: Python 3.13 Free-Threaded build (3.13t) NOT standard Python 3.10–3.12 Reason: Standard Python uses the Global Interpreter Lock (GIL), which blocks true parallelism. In low-latency systems, a 1–2ms delay caused by GIL contention is unaccep...

Primary Blocker: Finalizing the "handshake" between local P2P gameplay and the Supabase cloud layer, specifically regarding state persistence and security validation. Technical Architecture: Local-First / Cloud-Synced The game utilizes a hybrid architecture to ensure low-latency gameplay while maintaining global persistence: Real-time Gameplay: Driven by MultipeerConnectivity (P2P). The host drives the state, and clients apply messages locally. There is currently no Supabase traffic during active turns. Cloud Persistence: Supabase is used f...
I already accept card payments on my site; now I want to broaden the checkout so visitors can also pay with Stripe UPI first, and then Apple Pay, Google Pay and PayPal. You will receive my active Stripe account keys, so there is no account setup work—just the technical integration and any configuration changes inside the Stripe dashboard needed to switch on UPI and wallet payments. Recurring billing through Stripe UPI is essential because several subscription-based plans run on the platform. Once Stripe UPI is live and tested, we can move on to Apple Pay and Google Pay (using the standard Payment Request element or Stripe’s Web SDK) and finally wire up PayPal. Everything must run seamlessly inside the current Bubble workflows and respect my existing data structure...
...swapping existing shifts when something better comes along, pushing real-time notifications to me, and doing all of this fast enough to pick the shift up within milliseconds of it becoming available. Everything happens through the public web interface, so the script will have to handle login, schedule navigation, and any captcha or timing hurdles Amazon may insert. I’m happy for you to choose the stack—Playwright, Selenium, Puppeteer, Python, JavaScript, or whatever you believe will achieve sub-second reaction times—so long as the final solution can run headless on my own machine (Mac) or a small VPS and is straightforward to configure with my credentials. Acceptance criteria: • Captures an open shift within <1 second of its appearance during a live ...

...can decide if he wants to take another photo or if he wants to continue. • In case the user continues, the “Final Processing” starts. The final processing step removes the background from the image and verifies purchase data. The app has a free and a premium option. For the premium option, the user can buy in the app credits (in app purchase). If the user has premium credits, he will receive a full resolution photo. Otherwise, he can get the photo for free at a lower resolution. • The photo is then stored in the user’s media library. The backend/server logic does not have to be created. Only one part of the backend still needs to be changed: We have so far only a dummy logic to verify the purchase token with the google and apple servers. To create t...

I need a specialist to run a full-scale audit on a newly launched site, then roll out improvements across SEO performance, user-experience design, and core technical speed. Once our foundation is solid, I want to take the brand worldwide through organic channels—specifically social media relationship-building (ongoing engagement with followers and relevant influencers) and content marketing that can travel in multiple languages.

Looking for an Experienced PHP/Laravel Developer to Help Transform a Clinic Management System into a SaaS Product Hi, I have an existing Clinic Management Software (CRM) that I've been developing and actively using in production. My goal is to turn this product into a fully branded SaaS platform and bring it to market. I've made significant progress, but due to time constraints, I haven't been able to finish it on my own — and I'm now looking for a skilled developer to collaborate with. Current State of the Project: The core application is built with vanilla PHP (no framework), heavily utilizing JavaScript, jQuery, and AJAX for frontend interactions. I have also set up a Laravel-based SaaS project as the target platform. The goal is to migrate the e...

Scope The site will centre on three core sections: • About Me – a brief bio with one portrait image. • Projects Gallery – a grid or carousel that lets visitors browse projects quickly, with each project opening to its own detail view. • Contact Information – a simple form plus direct email and social links. I am open to the platform or stack you recommend, so long as it loads fast, is fully responsive, and can be updated without touching code (a lightweight CMS or page-builder is fine). Please optimise basic on-page SEO and set up Google Analytics so I can track visits from day one. Deliverables 1. Fully functional website hosted on my domain. 2. Design source files (Figma, X...

Every screen—from mobile to desktop—should open with a visually striking grid or masonry layout where each project thumbnail expands to show case-studies, process shots, and downloadable assets. Smooth page transitions, subtle hover effects, and balanced white space are important to me because the site itself must feel like part of the design portfolio it is presenting. You’ll handle the full stack: front-end build, back-end or headless CMS configuration, and any lightweight server setup needed so I can add or replace projects on my own later. Whether you choose React + Next, Vue, plain HTML/CSS/JS, or a platform such as Webflow or WordPress, keep the code base tidy, documented, and easy for a designer to maintain.
