As a React Developer and Full Stack Developer I build custom Web Application products for B2B clients, from interface to backend. Most of my work is Full Stack Developer React Node delivery, where a React frontend and a Node.js backend support one business workflow end to end. As a Node.js Developer I own the REST API logic, authentication, roles and permissions, and the data layer behind each product. My focus is practical Web Application Development that ships, scales, and stays maintainable, with clean API Integration at the core. Across 14+ years and 130+ completed projects I have built 60+ SaaS, CRM and dashboard products, 40+ admin panels and client portals, and 200+ REST API integrations. As a React Developer and Full Stack Developer with experience leading development teams of up to 6, I have shipped for 50+ EU and US B2B clients across SaaS platforms, CRM systems, marketplaces, booking websites and API Integration projects. As a React Developer I build Web Application interfaces with React.js, Next.js, TypeScript and Responsive UI , wired to live data through API Integration . As a React Frontend Developer and Frontend Developer I deliver usable, fast interfaces — data tables, filters, admin panels and client portals. On the backend side, as a Node.js Developer and Backend Developer I build the REST API layer, ExpressJS services, authentication, roles and permissions, payment flows and CRM integrations. Many clients come to me as a Node.js Developer when a frontend already exists but the API, the data model and the business logic need to be done right. As a Backend Developer I keep the Node.js layer predictable and documented, and as a Node.js Developer I handle the API Integration between third-party services, the database and the frontend. A typical Full Stack Developer React Node project for me looks like this: a SaaS platform or internal business tool with a React frontend, a Node.js backend, a structured database and an admin workflow for the team behind it. On every Full Stack Developer React Node build I design the database structure, the REST API , the dashboards and the permissions model so the product holds up as it grows. This Full Stack Developer React Node approach keeps frontend and backend in one system. Hiring one Full Stack Developer React Node engineer also keeps the React Developer and Node.js Developer decisions consistent across the whole build. I also work as a Directus Developer and Headless CMS Developer . On 20+ content-driven and data-heavy products I use Directus CMS or Strapi as a headless backend, which gives clients a clean admin panel and an API-ready foundation. As a Directus Developer I model the data, set roles and permissions, and connect a React frontend through REST API ; as a Strapi Developer I do the same on Strapi. Headless CMS work with Directus CMS pairs naturally with my React Developer and Node.js Developer delivery. Stack I use daily: React, React.js, Next.js, Node.js, TypeScript and JavaScript on the application side; ExpressJS, REST API and API Integration on the service side; SQL, MySQL, MongoDB, Firebase and Supabase for data; Directus CMS and Strapi for headless content. Authentication, roles and permissions, payment flows, dashboards, data tables, filters and admin workflows are standard parts of how I deliver Web Application Development . How I work on a Full Stack Developer React Node project: discovery and scope first, then architecture and backlog, design where needed, development in sprints, QA on staging, production release, and support after launch. As a Web Developer with 14+ years behind me, my main promise is delivery predictability — clear scope and no surprises. As a JavaScript Developer I write code the next developer can actually read and extend. Typical projects clients hire me for: SaaS platform development, CRM systems, admin panels, marketplaces, booking websites, lead generation websites, dashboards, client portals, internal business tools, e-commerce platforms and API-based Web Application work with workflow automation and business automation. Clients also find me under related searches that match my real stack. On the React side: React Native Developer , React Native App Developer , React Next.js Developer , React Developer Firebase , and Full Stack Developer Supabase React . On the full stack side: Python Full Stack Developer , Full Stack Developer AI , Full Stack Developer Shopify , Full Stack React , Full Stack Node.js React and Node.js React . On the backend: Node.js Backend Developer and Back End Developer Node.js . I also fit Front-End Developer Full-Stack , Python Developer , WordPress Developer , Mobile App Developer and Senior Full Stack Developer . If you need a React Developer , a Full Stack Developer React Node engineer, or a Node.js Developer for a serious product, I can take it from architecture through release and support.

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.

AI-Leveraged Delivery — ship 2× faster ⚡ Most developers say they're "fast." Then the staging environment shows up in week six. I do it differently — and I can show you the receipts. 🧾 ◆ 100% Job Success Score | Top Rated Plus | Full Stack Developer | React Next.js | Front End Developer ◆ I've been doing Software Development for 8+ years. In that time I've worked on everything from quick Landing Pages to multi-year SaaS platforms - and the thing that's stayed consistent is that clients get a working product, not a list of reasons why it's late. I work as a Full Stack Developer and Front End Developer, which means I'm comfortable owning the whole thing. React and Next.js are where I spend most of my time, but the stack goes deeper: Node.js, Python, PHP, Laravel, TypeScript, MongoDB, MySQL, PostgreSQL, SQL - whatever the project actually needs. I don't have a favourite technology. I have a favourite outcome: software that ships and works. ◆ FRONT-END DEVELOPMENT Front-End Development is my home base. I work with React, Next.js, Vue.js, Angular, JavaScript, TypeScript, HTML, HTML5, CSS, CSS 3, Bootstrap, jQuery, Redux, and Workbox.js for PWA builds. Web Design and Responsive Design aren't an afterthought - I work from Figma and Adobe Photoshop and care about how things look and feel across every device. PSD to HTML conversion, Front-End Development Framework setup, pixel-accurate implementation - all part of the job. ◆ FULL-STACK & BACK-END As a Full Stack Developer I connect the front end to a real backend: Node.js, Python, PHP, Laravel, NestJS, REST API, API Integration, SQL, MySQL, MongoDB, Database Architecture, Git, CI/CD. I've set up auth systems, payment flows via Stripe, third-party API Integration, and backend logic that doesn't fall over when traffic spikes. ◆ WHAT I BUILD ◆ SaaS platforms and Web Applications - React, Next.js, TypeScript, Redux, Tailwind, clean Web Design, fast load times, and Responsive Design that holds up on every screen ◆ AI-powered products - RAG pipelines, chatbots, OpenAI and Claude API Integration, document processing tools, pgvector retrieval ◆ E-commerce and WordPress - WooCommerce, custom themes and plugins, PSD to HTML, Web Development that converts ◆ Landing Pages and marketing sites - HTML5, CSS 3, Bootstrap, jQuery, Responsive Design, conversion-focused Web Design built for speed ◆ React Native mobile apps - cross-platform iOS and Android, shared codebase, App Store and Google Play ◆ Web Developer work across the full stack - API, Database Architecture, Laravel and PHP backends, Node.js services ◆ INDUSTRIES I've shipped projects across fintech and payments, healthcare and medical platforms, e-commerce and retail, EdTech, real estate, logistics and delivery, SaaS and B2B tools, marketplaces, social platforms, media and streaming, legal tech, travel and booking, fitness and wellness, and non-profit. Most verticals at this point. ◆ HOW I WORK I communicate early and directly. If scope is unclear I'll say so before we start, not after week four. If an approach won't work I'll tell you - and offer an alternative. Staging live in week one, weekly updates, clean code your next developer won't hate. ◆ RELATED EXPERTISE Full Stack Developer: web developer, react developer, wordpress developer, mobile app developer React Next.js: nestjs, workbox.js, web developer, front end developer Front End Developer: web developer, full stack developer, react developer, react ◆ READY TO START ASAP
