Andrej P.

React & Next.js Developer | Web Apps, Migrations & Automation

If you need someone to take ownership of a web product, I can help. I work with businesses in two situations: you need a developer who can scope, build, deploy, and maintain a new product or system, or you have something live that is slow, dated, poorly held together, or outgrowing its platform. I replace or improve it without disrupting the business while the work is underway. I am Andrej, a Top Rated Plus developer with more than five years of experience shipping production web applications and running e-commerce operations end to end. ✦ Projects I Take Ownership Of The work I get hired for most is technical ownership. That means running large-catalog e-commerce stores end to end: storefront, distributor integrations, platform migrations, decisions about systems and apps, design direction, and the automation tools staff and customers actually touch, including order, email, SMS, invoice, and packing slip flows. It also means advertising technology: high-performance browser products and the internal tooling around them, optimization for high-volume delivery across a large publisher network, and the systems a team uses to build, review, and release their work. Weekly deliverables on tight deadlines, with me proposing the architecture and automation rather than waiting for a complete spec. That is the pattern. One accountable developer who owns the outcome, not a pair of hands executing tickets. ✦ Where I Fit Web apps, platforms, and MVPs. Next.js, React, TypeScript, and Tailwind. I have worked on hiring tools, healthcare booking, analytics dashboards, marketplaces, and motion-heavy marketing sites. Migrations and modernization. I take over legacy or messy stacks and ship clean replacements without disrupting live operations. That includes WordPress to Next.js, WordPress to BigCommerce on large catalogs while preserving SEO equity, and React and Laravel cleanup on distributed teams. E-commerce operations. I have owned stores over multiple years, handled complex catalog migrations, checkout and variant logic, companion internal tools, and the ongoing work that keeps a store operating well. Integrations and automation. I work with third-party APIs, distributor feeds, internal dashboards, and notification systems. I also remove manual steps from a team's regular work. ✦ Tech Frontend: React, Next.js, TypeScript, Tailwind CSS, SCSS, GSAP Backend and data: Node.js, PostgreSQL, Firebase, REST and GraphQL APIs E-commerce: BigCommerce, custom storefronts, checkout and variant logic Infrastructure: Vercel, Linux server administration with nginx and pm2 When a project needs backend work, an integration, or an internal tool, I handle it. You do not need to coordinate three freelancers. ✦ What Clients Say "Andrej has been such an asset. He has done multiple developments to our websites and internal systems as well as improved design, customer experience and aesthetics. He is extremely knowledgeable, fast and reliable." "Andrej did an excellent job comparing HTML with the Figma design. He has a sharp eye for detail and delivered precise, thorough feedback. His work was accurate and reliable throughout the task." "Absolutely love working with this guy. Professional, skilled and always on time." ✦ How I Work I take ownership and communicate clearly about priorities, tradeoffs, and what needs to happen next. I use Claude, Cursor, and Copilot to move quickly. Five years of depth is what keeps the output production ready after release. I am reliable on long-term contracts. My current clients have stayed for years. Retention is the strongest proof I can offer. Cross-team friendly. Standups across time zones, GitHub workflows, async first. ✦ Who This Works Best For This is a good fit for people who own a real product, want a long-term technical partner, and care about how things get built. Rebuilds, migrations, platform work, and ongoing ownership are where I add the most value. For a single small page change, I may not be the best fit. ✦ Want a Read Before You Commit Send me your URL, repo, or brief. I will tell you what I would improve and in what order.
