Mykyta T.

Senior Full-Stack Engineer | React, Node.js, APIs, AI & Automation

Some teams need a feature shipped: a React app, a Node.js backend, an API integration, a data pipeline. Others need manual work automated: client reporting, CRM updates, lead follow-up, data entry. And some need a senior engineer to own the whole technical side. I do all three. 11,000+ hours on Upwork. 100% Job Success. $200K+ earned across 30 projects, and over a decade of shipping production software. What I build: React and Node.js apps, API integrations that connect your CRM, billing, reporting, and scheduling tools, data pipelines, and AI agents where they earn their keep, in n8n or plain code when the tools run out. When you need more than a build, I step in as a fractional CTO or solutions engineer: architecture, code reviews, hiring, vendor decisions. Every build ships with logging, review steps, fallbacks, and a plain-English handover, so nothing fails silently after launch. Tell me what you're trying to ship, or what your team still does by hand. I'll tell you how I'd take it on.
