USA Project-Based Software Outsourcing Company
We are a software development company based in USA (Miami, Florida) that delivers project-based software development services.
Our Clients
We deliver complete projects, from start to finish.
B2B E-commerce Platform
We worked with Bari, an online sales platform connecting retailers and wholesalers, to build a complete web application from scratch. Starting with requirements definition, we assembled a 6-person team—3 backend engineers, 2 frontend developers, and a project manager—and delivered the entire platform in 6 months.
The project included a RESTful backend built on .NET Core, a React frontend, and GraphQL integration. We handled everything: architecture decisions, development, testing, deployment, and post-launch support. Today, the platform processes millions in transactions and serves 12 distributors and 230 retailers. We continue providing maintenance services, demonstrating how project-based outsourcing delivers lasting value.
Smart City Waste Management System
BinSensors came to us with a vision: improve waste collection in cities through smart sensors and mobile apps. We took ownership of the entire project—from initial concept to deployment. With a 3-person team (backend, frontend, and project manager), we built a full REST API backend and a web portal for tracking bins, managing drivers, and analyzing efficiency metrics.
The project-based model worked perfectly here. BinSensors didn't need to hire developers, set up infrastructure, or manage day-to-day development. They defined the goals, and we delivered. The system now serves 12 garbage collection companies across 5 cities, saving thousands of gallons of fuel and driving hours annually. It's a complete project that runs independently.
Secure Collaboration Platform
HighSide needed a secure file sharing and collaboration platform with encrypted storage and data access management. They had the vision but needed a team to execute the entire project. We took the project from requirements to production, handling architecture, development, DevOps, and deployment.
The project included Python backend development, AWS infrastructure, Kubernetes orchestration, and Docker containerization. We managed the full stack, ensuring security, scalability, and performance from day one. The client focused on business strategy while we handled all technical execution—exactly what project-based outsourcing is designed for.
Payment Gateway Integration
For a fintech client, we built a complete payment gateway system from the ground up. The project required deep integration with multiple payment processors, fraud detection, compliance with financial regulations, and a robust API for third-party integrations. We assembled a specialized team with expertise in payment systems, security, and financial technology.
From initial planning through deployment and certification, we managed every aspect of the project. The client didn't need to understand the technical complexities—they provided business requirements, and we delivered a production-ready payment gateway that processes transactions securely and reliably. This is project-based outsourcing at its best: complete ownership, clear deliverables, and predictable outcomes.
What These Projects Have in Common
Each of these clients chose project-based outsourcing because they needed a complete solution delivered on time and within budget. They didn't want to manage developers, review code commits, or worry about technical details. They wanted to define requirements, set deadlines, and receive a working product.
That's exactly what we delivered. In every case, we took full ownership of the project lifecycle—requirements analysis, architecture design, development, testing, deployment, and initial support. Our clients could focus on their business while we handled everything technical. The projects were delivered on schedule, met specifications, and continue to serve their users effectively.
Whether it's a B2B platform, a smart city solution, a security-focused application, or a financial system, project-based outsourcing works when you need a complete project delivered by a team that owns the outcome. We've proven this model works across industries, technologies, and project sizes.
