Senior Full Stack Developer / Software Architect (Long-Term) We are looking for an experienced Senior Full Stack Developer with strong software architecture skills to help build a modern service marketplace platform. This is not a traditional booking system or CRM. We are building an end-to-end platform that connects customers with independent service providers while managing the entire operational workflow. Customers book services through our platform, while a network of verified partners performs the work. Our platform manages everything from lead generation to final payment. The platform includes: * Customer Portal * Partner Portal * Internal CRM * Sales CRM * Operations Dashboard * Booking & Scheduling * Intelligent Partner Assignment * Pricing Engine * Billing & Invoicing * Partner Settlements * Quality Assurance * Analytics & Reporting Initially, the platform focuses on residential services such as move-out cleaning and pre-sale cleaning. Over time, the same platform will expand into recurring home services, short-term rental services, property management, condominium maintenance and additional service verticals. Our goal is not to build separate systems for each service. We are building a single scalable platform capable of supporting multiple service categories, countries, languages and partner networks.

Hello, Building a single scalable platform with complex workflows like partner assignment, billing, and analytics is tricky—I’ve worked on a similar marketplace where we had to handle multiple service types and partner networks while keeping the system maintainable. For this, I’d use a modular Node.js backend with a React frontend, keeping the architecture clean to avoid spaghetti code as features grow, and the biggest win will come from isolating the partner assignment logic early. I’ll structure the system so each module (billing, scheduling, etc.) can be tested independently, which makes debugging easier when changes come in. The goal is a platform that scales without becoming a maintenance nightmare, so the initial focus will be on clear contracts between components and thorough logging to catch issues before they reach users. This approach should give you a stable foundation that’s easier to extend for new services or markets. Happy to discuss the current setup and see if it fits what you need. I can start right now Thanks, Denis

Hi, I can help architect and build your service marketplace as a scalable platform rather than a collection of separate systems for each service vertical. With my 9+ years of full-stack development experience, I have strong experience designing backend architectures, customer and admin platforms, workflow-driven systems, integrations, and scalable database-driven applications. I understand the key challenge here is creating a flexible core that can support different service categories, countries, languages, pricing models, partner networks, and operational workflows without requiring a complete rebuild each time. I can contribute across the full platform architecture, including customer and partner portals, CRM workflows, booking and scheduling, partner assignment, pricing, billing, settlements, QA, and analytics—with a strong focus on clean domain boundaries and long-term maintainability. I would be happy to discuss the platform vision and help define the architecture and development roadmap for the first service vertical and future expansion. Thanks, Cesar

With over a decade of experience in full-stack development, software architecture, and project management, I believe I bring the perfect combination of skills for your service marketplace platform. Not only am I adept at creating clean, functional, and visually engaging digital solutions like you're seeking, but I'm also well-versed in using various frameworks such as Laravel and React to develop powerful multi-layered platforms- essential for building your end-to-end portal. Furthermore, my experience includes developing CRM and data-driven platforms across different sectors. This will be valuable in constructing the partner portal and CRMs within your system. It'd also ease the process of incorporating additional verticals as your business diversifies over time. On top of all this, I’m not just a coder; I also consider how to make a system more user-friendly on all touchpoints—I’d ensure that your customer and partner portals are easy to use while still offering comprehensive functionalities.

The biggest challenge here isn't the customer booking flow, it's keeping the operational workflow flexible enough to support new service categories, countries, and partner networks without rewriting core business logic every time. I'd start by defining the domain boundaries first, then build the shared services around booking, pricing, partner assignment, billing, and settlements so each vertical extends the platform instead of duplicating it. With PHP and MySQL, getting the data model right early matters just as much as the UI. Things like partner availability, pricing rules, and assignment logic can become bottlenecks if they're tightly coupled. I'd also keep the customer portal, partner portal, and internal tools separated at the application layer while sharing the same core business services, which makes the platform easier to maintain as it grows. This approach keeps the foundation ready for future expansion instead of solving only today's residential services.
