Senior Full-Stack Developer | 10+ Years Building Production-Grade Laravel & Vue.js Applications I've spent the past decade building and scaling web applications for agencies and startups across Germany. You need a developer who architects solutions that drive revenue, scale with your business, and are built to last. That's what I do. I specialize in Laravel and Vue.js full-stack development, covering the entire lifecycle: database architecture, REST API design, and polished frontends with TypeScript and Tailwind CSS. ⚙️ Laravel & PHP Backend ✅ Application architecture: REST APIs, queues, jobs, events, scheduling ✅ MySQL database design, optimization, and migrations ✅ Third-party API integrations and payment systems ✅ Authentication, authorization, and multi-tenancy 🖥️ Vue.js & Nuxt.js Frontend ✅ Single-page and server-rendered applications ✅ TypeScript and Tailwind CSS for responsive, clean UI ✅ Component-driven architecture and state management 🛠️ AI Code Rescue & Modernization AI tools generate code fast, but rarely code that scales. I audit, refactor, and stabilize AI-generated codebases, turning fragile prototypes into production-ready applications with proper structure and testing. If your AI-built project is breaking under real traffic or becoming impossible to maintain, I can fix it. 📌 What Working With Me Looks Like Clear updates, honest timelines, and no disappearing acts. I've been told I have that "German precision" thing going on, and I'll take it. Your deadlines matter to me. Based in Germany (CET), available 30+ hours per week. Fluent in English, native German. I respond fast and keep meetings productive. Docker, CI/CD, and deployment are part of my workflow, not an afterthought. Whether you need a Laravel SaaS built from scratch, a broken codebase rescued, or a Vue.js frontend that actually performs: send me your project details and I'll get back to you within 24 hours.

Full Stack Developer and AI Engineer - CEO and Co-Founder of Invirial, 𝐚 𝐬𝐞𝐧𝐢𝐨𝐫 𝐭𝐞𝐚𝐦 𝐨𝐟 𝟗+ shipping B2B SaaS and Fintech products. Track record: Member since 𝟐𝟎𝟏𝟐 · 𝟏𝟎𝟎% JSS · $𝟔𝟎𝟎𝐊+ earned on this profile · $𝟒𝐌+ earned across our agency. To be clear upfront: I don’t write the code myself on every project. As Co-Founder, I scope, architect, and oversee delivery — my Full Stack Developers and AI Engineers ship. That’s why clients hire us instead of a solo freelancer: real capacity, senior oversight, and no single point of failure. 𝐖𝐡𝐚𝐭 𝐰𝐞 𝐛𝐮𝐢𝐥𝐝 Most clients come to us with one of two problems: they need a product built properly from scratch — an MVP that ships in weeks, not quarters — or they have an existing system that needs a senior Full Stack Developer or AI Engineer team to take ownership and move it forward without hand-holding. We’re a Full Stack Developer and AI Engineer team in one shop. That matters in 2026 because the line between the two has collapsed: modern SaaS products need React and Next.js on the frontend, Node and Python on the backend, and LangChain, RAG pipelines, and OpenAI or Claude integration as core features — not as a bolt-on. We own the whole stack end-to-end so you don’t have to coordinate three vendors. Our Full Stack Developers ship in: React, Next.js, Node.js, TypeScript, JavaScript, Python, Django, FastAPI, MongoDB, PostgreSQL, Supabase, Tailwind CSS, shadcn/ui, Stripe, AWS, Docker, REST APIs, third-party API integration. MERN stack and Next.js + Supabase + Stripe are our two default builds for SaaS MVPs. Our AI Engineers ship in: Python, LangChain, LangGraph, OpenAI API (GPT-4o, GPT-5), Claude / Anthropic API, RAG pipelines, vector databases (Pinecone, Chroma, FAISS, Weaviate), LlamaIndex, FastAPI, Hugging Face, fine-tuning (LoRA/QLoRA), n8n, Make. com, AWS Bedrock, Azure OpenAI, prompt engineering, AI agent development, chatbot development, and voice stack (Vapi, ElevenLabs, Twilio). We don’t do prompt-only ChatGPT wrappers. Our AI Engineers ship real agentic workflows — multi-step reasoning, tool calling, memory, guardrails, and production deployment. 𝐖𝐡𝐚𝐭 𝐰𝐞 𝐝𝐞𝐥𝐢𝐯𝐞𝐫 Whether you need a React developer for a SaaS dashboard, a MERN stack developer for a full product build, an AI agent developer for a multi-agent system, a generative AI engineer for a RAG chatbot, or a Next.js developer to migrate from WordPress or Bubble — we have the right senior on the team for it. Common deliverables: B2B SaaS MVPs from scratch, Fintech platforms with Stripe and compliance-aware architecture, RAG chatbots and knowledge-base assistants, AI automation with n8n + Claude, AI voice agents, admin dashboards with auth and RBAC, no-code-to-code migrations (Bubble/Lovable/Framer → coded stack), and ongoing engineering for products in growth. Recent Full Stack Developer and AI Engineer projects A snapshot of the project archetypes our team ships most often: 🔘 Fintech SaaS platforms — Next.js + Supabase + Stripe builds with subscription billing, KYC flows, role-based access, and compliance-aware architecture. Senior Full Stack Developer–led. 🔘 RAG chatbots and knowledge-base assistants — production-grade retrieval pipelines built by our AI Engineers using LangChain, Pinecone, and OpenAI or Claude, with guardrails, source citations, and LangSmith evaluation in place from day one. 🔘 AI agent and agentic workflow systems — multi-agent architectures using LangGraph, OpenAI Agents SDK, or n8n + Claude for lead generation, CRM enrichment, and internal operations automation. Built by AI Engineers who’ve shipped agents in production, not just demos. 🔘 B2B SaaS MVPs from scratch — full-cycle Full Stack Developer builds covering product architecture, React/Next.js frontend, Node or FastAPI backend, payment integration, and AWS or Vercel deployment. Designed for clients who need to launch fast and scale without a rebuild. 🔘 AI-augmented Full Stack rebuilds — taking an existing B2B SaaS or Fintech product and adding LLM-powered features (chat with your data, AI copilots, smart automation) through our combined Full Stack Developer + AI Engineer workflow. The hybrid build is what we do best. Why clients pick our Full Stack Developer and AI Engineer team over a solo freelancer A senior team of 9+ means we ship faster than a solo Full Stack Developer or AI Engineer and survive bus factor. CEO and Co-Founder oversight on every project means architecture decisions get made by someone with 14+ years of shipped products behind them — not by whoever happens to be assigned to your account. And because we work as a single agency rather than a marketplace of strangers, the engineer reviewing your code on Friday is the same one fixing the bug on Monday. If you’re building a B2B SaaS or Fintech platform and need a senior team that ships, let’s talk.
