🚀 Building production-ready SaaS platforms, scalable web architectures, and high-performance frontends.
Hi, I am Serhii, an officially registered Freiberufler (independent contractor) based in Germany. I specialize in engineering robust web applications, startup MVPs, and complex SaaS solutions for businesses that value reliability, scalable architecture, and transparent processes.
Over the past 6+ years, I have successfully delivered multiple end-to-end projects, focusing on building systems that handle real production workloads—not just prototypes.
🔹 Workflow & Professional Standards
Local DACH Partner: Based in the Central European Timezone (CET), I provide seamless communication in English, German, and Russian. You get the legal and operational reliability of working with a Germany-based professional.
Transparent Processes: I strictly manage projects using Scrum and Jira methodologies, ensuring you have complete visibility into sprints, deliverables, and budget allocation.
AI-Native Efficiency: I leverage autonomous AI agents and modern tooling to accelerate code generation, conduct deep architectural analysis, and automate workflows, reducing your time-to-market.
Quality First: I do not compete on cheap labor; I compete on engineering excellence. My baseline for a simple landing page starts from €500, with custom SaaS platforms priced according to their architectural complexity.
🔹 Full Stack Web Development & SaaS
As a Full Stack Developer and React Node Full Stack Developer, I design comprehensive systems combining modern frontends with powerful backend services. I have extensive experience building SaaS platforms with complex billing logic (such as electronic invoicing for the German market) and AI-powered data management systems. My solutions are designed to scale, process heavy API traffic, and maintain exceptional uptime.
🔹 Frontend Development (React & Next.js)
For teams searching for a React Developer, Next.js Developer, or Frontend React Engineer: I build modern SPAs, SSR applications, and complex SaaS dashboards. Leveraging TypeScript, Next.js, and Tailwind CSS, I ensure pixel-perfect, responsive UIs. I am obsessed with frontend performance, consistently optimizing core web vitals to achieve "Perfect 100" Google Lighthouse scores.
🔹 Backend Development (Node.js/NestJS & Python)
As a Node.js Developer and Backend Engineer, I architect robust REST and GraphQL APIs using NestJS, Express, and Node.js. Furthermore, as a Python Developer, I build advanced data pipelines, backend automation, and AI integrations using Python and FastAPI.
🔹 Core Technologies & Roles I Fill:
Frontend: React Developer, Next.js Developer, Frontend Web Developer, Tailwind CSS, SPA, SSR.
Backend: Node.js Developer, NestJS, Express, Python Developer, FastAPI.
Database & Infrastructure: Prisma, PostgreSQL, MongoDB, Redis, Headless Architecture.
Methodologies: Scrum, Jira, Agile, RAG-based AI integration.
Whether you need a dedicated Frontend Engineer to perfect your UI or a Senior Full Stack Web Developer to architect your next SaaS platform from the ground up, I deliver maintainable, production-ready code.
