🏆 $3M+ Earned on Upwork — Placing Me Among a Very Small Percentage of Freelancers on the Platform
Looking for a veteran full-stack web development team to bring your CMS, CRM, ERP, SaaS, marketplace, or data platform to life? We don’t do quick hacks or throwaway code. We build systems that last.
Results:
- 100+ SaaS and CRM platforms launched from scratch
- 300+ automation tools built
- 150+ POS, Web-to-Print, and location-aware applications delivered
- platforms serving 20M+ users with 99.99% uptime
- ERP systems reducing operational overhead by 40%+
- web automation saving 1,000+ hours per month per client
We are a senior team of full-stack engineers with 25+ years of hands-on web development experience and 600+ successful projects delivered across 40+ industries. We focus on long-term, production-grade systems where architecture, performance, and business logic truly matter.
We operate as web developers, React developers, WordPress developers, mobile app developers, and backend engineers, delivering full-cycle product development using PHP, JavaScript, and Python. Our stack includes Laravel, Symfony, Vue, React, Angular, Node.js, Next.js, TypeScript, jQuery, MySQL, PostgreSQL, Redis, and modern API-first architectures. Whether you need a full-stack developer (PHP, JavaScript, Python), a Python full-stack developer, or a PHP Laravel Angular combination, we cover the entire lifecycle end to end.
As front-end full-stack specialists, we build high-performance dashboards, SPAs, PWAs, and data-heavy interfaces using React, Vue, Angular, Next.js, and TypeScript. Our React team focuses on performance, scalability, and UX logic, while our backend engineers design robust systems with REST and GraphQL APIs, multitenant architectures, role-based access control, billing engines, reporting pipelines, and audit trails.
We also work as software developers and full-stack AI engineers when projects require machine learning, automation, or advanced data processing. Our Python full-stack teams build data pipelines, AI-assisted workflows, and automation systems that reduce operational overhead and deliver measurable business value. This includes AI-enabled backends, LLM integrations, and ML-driven platforms.
As WordPress developers, we build custom plugins, headless CMS architectures, and React or Vue frontends. As mobile app developers, we deliver iOS and Android applications using React Native and native stacks, tightly integrated with scalable backends. As PHP full-stack developers, we handle both greenfield builds and complex legacy modernization.
We regularly work as:
- full-stack web development teams on SaaS, ERP, CRM, POS, LMS, and Web-to-Print platforms
- full-stack squads on marketplaces, fintech, and data platforms
- Python full-stack teams on automation and analytics pipelines
- PHP Laravel Angular teams on enterprise systems
- React and front-end full-stack teams on complex UI platforms
- full-stack AI teams on ML-powered products
We handle the full spectrum: system architecture, development, DevOps, CI/CD, Docker, AWS, GCP, Apache, Nginx, and long-term maintenance. We design systems that scale in production, survive real-world usage, and support sustainable business growth.
Whether you need a web developer to extend your platform, a React developer to rebuild your frontend, a WordPress developer for custom CMS logic, a mobile app developer to complement your product, or a full-stack AI team to connect data, automation, and intelligence, we bring decades of hands-on experience and production-grade delivery.

You need software that solves a real problem, built right the first time, by people who understand your business and not just your stack.
I'm Orest, founder of SoftDoes. We're a U.S.-based custom software firm working with:
• Non-technical founders with a vision
• Technical leaders who need help but not additional headcount
• Business operators solving operational complexity
Our team has delivered across healthcare, fintech, construction, legal, real estate, and regulated industries where compliance-readiness is required and getting it wrong isn't an option.
Our clients tend to show up in one of three situations: they have a product vision and need someone to build it, they have internal engineering that's stretched too thin, or they have operational complexity that off-the-shelf software simply can't fix. We've handled all three.
What we deliver:
• Custom software and SaaS platforms built for scale
• AI implementation and automation built into real workflows
• Web and mobile applications
• Cloud infrastructure on AWS, GCP, and Azure
• Full-stack development across React, Next.js, Node.js, and Python
What clients tell us, consistently: we listened, we delivered what we said we would, and they didn't have to babysit us to get there. A healthcare founder went from concept to a live, compliant product in under six weeks. A construction company replaced five fragmented tools with one custom operations platform. A fintech team cut onboarding time in half with an AI-assisted workflow we built in a single sprint.
We work best with companies that are big enough to need real software and clear-eyed enough to know that building it wrong the first time costs more than doing it right.
If that's where you are, let's talk.
