While I am establishing my presence on Upwork, I offer high-level professional execution at a competitive rate. You get a developer who understands the "big picture" and knows how to build products from the ground up.
✅ What I do best:
Develop Single Page Applications (SPA) using Angular, React, TypeScript, and RxJS
Build responsive and pixel-perfect layouts with SCSS, HTML5, and Tailwind CSS
Integrate RESTful APIs and third-party services
Optimize applications for performance, SEO, and accessibility
Collaborate in Agile/Scrum teams using Git, Jira, Linear, and CI/CD pipelines
🛠️ Tools & Technologies:
Angular • React • Webflow • RxJS • TypeScript • JavaScript • HTML5 • SCSS • Tailwind • Git • REST APIs • Pixel Perfect
💬 I value clean, maintainable code and clear communication. I'm ambitious, detail-oriented, and always eager to learn new things. Let’s work together to bring your ideas to life — and turn them into beautiful, fast, and reliable web experiences.
📌 I'm available for part-time and full-time remote projects, and open to relocation if needed.
👥 Need more than just a solo developer? I work with a trusted small team — including a project manager, QA tester, and another frontend developer — to offer complete, reliable solutions when needed. You'll get clean code, tested functionality, and a smooth workflow — without the hassle of assembling a team from scratch.
