Senior Full-Stack Engineer / Software Architect with 15+ years of experience building, modernizing and maintaining production software for clients worldwide. With 36,000+ hours and 100+ projects completed on Upwork, I've worked across the full software development lifecycle — from requirements and architecture through implementation, testing, deployment and long-term maintenance. My core expertise is in the Microsoft/.NET ecosystem: • C# / ASP.NET Core / .NET 6–8 • REST APIs & API-first architectures • Entity Framework Core / SQL Server / PostgreSQL • Angular / TypeScript / React • Azure / AWS / CI/CD • Microservices, modular monoliths & distributed systems • RabbitMQ / Redis / MongoDB • Application modernization and legacy system migration I particularly enjoy taking ownership of complex or long-running projects where understanding the business domain is just as important as writing the code. I have extensive experience working independently with international teams, communicating directly with stakeholders, investigating production issues, improving existing architectures and delivering software that needs to work reliably in real-world environments. More recently, I've incorporated AI-assisted development into my workflow — using AI for requirements analysis, planning, implementation, testing, code reviews, documentation and refactoring, while maintaining engineering standards and carefully reviewing generated code. If you need a senior engineer who can do more than implement tickets — someone who can understand the bigger picture, make technical decisions and take ownership of delivery — I'd be happy to discuss your project. Outside of work, I enjoy spending time with my two kids and running. I've completed 40+ marathons, which has taught me a lot about consistency, patience and long-term goals. I'm always open to interesting projects and challenging technical problems. If you're looking for an experienced engineer who takes ownership and cares about delivering quality software, let's talk. **15+ years experience | 36,000+ Upwork hours | 100+ projects | 100% Job Success | Top Rated Plus**

🏆 Top Rated Plus | $90K+ Earned | 7,000+ Hours on Upwork | 100% Job Success I build and maintain full-stack web applications using MERN and MEAN, with a strong focus on React, Angular, Node.js, TypeScript, MongoDB, and API-driven architectures. With 9+ years in full-stack development, I’ve worked across SaaS, healthcare, enterprise, FinTech, eCommerce, and internal business platforms. A big part of my work involves taking an existing product or codebase, understanding how it works, fixing what’s holding it back, and adding new functionality without creating unnecessary complexity. What I work on ✅ MERN applications — React, Node.js, Express, MongoDB, TypeScript ✅ MEAN applications — Angular, Node.js, Express, MongoDB ✅ SaaS platforms, dashboards, admin panels, portals, and business applications ✅ Healthcare applications, patient portals, healthcare workflows, provider dashboards, and data-driven systems ✅ REST APIs, third-party integrations, authentication, role-based access, and business workflows ✅ Existing application modernization, feature development, bug fixing, and performance improvements ✅ AI integrations, OpenAI APIs, AI assistants, automation, and intelligent workflows ✅ Enterprise applications and internal tools with complex user roles and workflows Core Technologies Frontend React.js • Angular • Next.js • TypeScript • JavaScript • HTML5 • CSS3 • Tailwind CSS • Responsive UI Backend Node.js • Express.js • REST APIs • Microservices • .NET Core / ASP.NET • C# Databases MongoDB • PostgreSQL • MySQL • SQL Server Cloud & DevOps AWS • Azure • Docker • CI/CD • Git AI & Automation OpenAI API • GPT integrations • AI chatbots • Workflow automation • Data processing Healthcare Experience Healthcare is one of the areas I regularly work with, particularly where applications involve patient/provider workflows, dashboards, portals, scheduling, records, role-based access, reporting, integrations, and sensitive business data. I understand that healthcare applications need more than a good-looking interface. Permissions, data flow, reliability, auditability, integrations, and predictable workflows matter just as much as the frontend and backend implementation. Some of my work • Engagifii — Full-stack SaaS platform using Angular and .NET Core • Large-scale web platforms using React, Node.js, MongoDB/PostgreSQL, and cloud infrastructure • Enterprise workflow and business applications • Healthcare-oriented platforms involving dashboards, portals, workflows, and integrations • AI-enabled products with intelligent workflows and automation • Microsoft-related enterprise projects using .NET and SharePoint I’m comfortable joining an existing development team, taking ownership of a specific area, or handling a full feature from UI → API → database → deployment. If you’re looking for a senior developer for a MERN, MEAN, React, Angular, Node.js, or healthcare application, feel free to reach out.

⭐ Senior Full Stack Developer | 50+ Products Shipped ✉️ 𝗠𝗘𝗦𝗦𝗔𝗚𝗘 𝗠𝗘 I typically respond within 12 to 24 hours, and urgent projects can be prioritized. I lead a senior engineering team that builds, scales, and rescues complex web and mobile products. Whether you need a single Senior Full-Stack Engineer or a dedicated team that plugs in and ships from day one – we move fast and deliver production-grade results. Over 50+ completed projects, we've helped startups and scale-ups go from prototype to release, and stepped in as the core engineering team when products needed to grow. We work primarily with Node.js and Nest.js on the backend and React / Next.js on the frontend – the same stack that powers most modern, high-load SaaS platforms. 🎯 WHAT YOU GET WHEN YOU HIRE US – 100% completion rate – every project delivered, backed by a 100% Job Success Score across 6000+ hours on Upwork – Fast start & team scaling – we onboard in days, not weeks, and scale the team up or down as your roadmap demands – AI-accelerated delivery – we integrate AI tools into our development process to improve code quality and ship faster – Full cycle – from prototyping and UX to architecture, development, and release 🏆 RESULTS "I highly recommend Pavlo - he will be my goto next time for any work like this. He understood exactly what I needed and was really fast to act. One of the best freelancers Ive used on Upwork!" – Lauren B., Client "Pavlo and his team were highly responsive, professional, and extremely efficient in diagnosing issues and identifying the root causes of several problems in the codebase. Their debugging process was structured and precise, and their recommendations during the code review were very valuable in improving the overall stability, performance, and maintainability of our system." – Client, Product Manager, SaaS Platform SELECTED PROJECTS – CaJu AI – an enterprise AI platform with real-time AI workflows, scalable Node.js backend services, and React-based interfaces for compliance-focused customer support automation. – CookieFirst – a large SaaS platform where we became the core engineering team, scaling the product, expanding functionality, and improving performance. – Ragusa Express – a booking platform with online reservations, payments, backend modernization, and React frontend improvements. TECHNICAL STACK Backend: Node.js, Nest.js, Express.js, Laravel, Symfony (TypeScript, PHP, Python) Frontend: React, Next.js, Vue.js, Tailwind CSS, SCSS/Sass Mobile: React Native, Java, Kotlin, Swift Cloud & Tools: AWS, Docker, NGINX, Supabase, PostgreSQL, MongoDB, DevOps, Figma If you're looking for a reliable Senior Full Stack partner who works in Node.js, Nest.js, and React and can take ownership from idea to launch – send me a message and tell me about your project. ENGAGEMENT MODELS You can bring on a single Full Stack Developer for focused feature work, a dedicated Backend Developer to own your Node.js services, or a full pod combining Full Stack Developer and Backend Developer roles with a React specialist on top. Most clients start with one Full Stack Developer or one Backend Developer and scale up once trust is established – we've grown from a single Node.js Backend Developer to an eight-person team on more than one long-term engagement. WHY NODE.JS AND REACT We standardized on Node.js and React because they let a single Full Stack Developer move across the stack without context-switching, and they give a Backend Developer and a React engineer a shared language when APIs and UI need to evolve together. A Node.js Backend Developer on our team typically ships REST or GraphQL services that a React frontend consumes within the same sprint, which is the main reason clients hire a Full Stack Developer from us instead of stitching together separate backend and frontend contractors. A FEW THINGS CLIENTS ASK BEFORE HIRING Can I hire just one Backend Developer? Yes – many engagements start with a single Backend Developer handling Node.js architecture while we hold a Full Stack Developer in reserve for later. Do you offer a trial period? Yes, a short paid trial with one Full Stack Developer or Backend Developer is the easiest way to check fit before scaling the team. Can you work backend-only? Yes – some clients only need a Node.js Backend Developer, others need a full Full Stack Developer team covering React end to end. Whether you need a Full Stack Developer or a Backend Developer, message me with your stack and timeline and I'll match you with the right Full Stack Developer from the team within 24–48 hours. Best regards, Pavlo Jedi at Red Carlos Solutions
