⭐ 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

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
