Project details

I build clean, modern, production-ready web applications end to end, frontend, backend, and database.

I'm a Senior Full-Stack Developer and Software Architect (M.Sc. Computer Science, TU Berlin). I've built and launched multi-tenant SaaS platforms from scratch, including my own product, Time-Dock.de, so you get someone who ships real, maintainable products, not throwaway demos.

Stack: React, Next.js, TypeScript on the frontend; Python, FastAPI, PostgreSQL on the backend. Clean architecture, authentication, API design, and deployment included where needed.

Whether you need a dashboard, an internal tool, a SaaS MVP, a customer portal, or a landing page with real functionality, I'll build it properly: clear structure, documented code, and a product that actually works and can grow with you.

Message me with what you have in mind and I'll tell you honestly what's realistic and how I'd approach it.

About Elias

Elias M.Status: Offline
Software Architect & Senior Full-Stack Developer | AI, RAG & LLM Apps
Berlin, Germany - 2:20 pm local time
I build production-grade AI systems and full-stack applications, end to end.

I'm a Senior Full-Stack Developer and Software Architect (M.Sc. Computer Science, TU Berlin) with deep expertise in applied AI. I ship real products that run in production and serve real users, not prototypes that break the moment they leave the demo. One example is my own SaaS product, Time-Dock (time-dock.de), which I designed, built, and launched solo, from first idea to a live multi-tenant platform.

WHERE I BRING THE MOST VALUE

AI, LLMs & knowledge retrieval
- Custom AI chatbots and assistants tailored to your business
- RAG systems (Retrieval-Augmented Generation) over your documents, PDFs, or knowledge base
- Advanced retrieval pipelines: hybrid search (dense embeddings + BM25), cross-encoder reranking, and reciprocal rank fusion for accurate, grounded answers
- Knowledge graphs and graph-based retrieval to connect and query structured knowledge
- AI agents and agentic workflows that automate multi-step research and reasoning
- GDPR-compliant, on-premise LLM deployments (vLLM, Ollama) for sensitive data
- Built at production scale: systems handling millions of documents

Web scraping & data extraction
- Reliable, maintainable scrapers for complex websites and official registries
- Structured extraction from unstructured sources: PDFs, scanned documents (OCR), and HTML
- Named entity recognition and information extraction from domain-specific text
- Clean, ready-to-use output: CSV, JSON, or directly into your database

Full-stack development
- Frontend: React, Next.js, TypeScript
- Backend: Python, FastAPI, PostgreSQL, Redis
- Clean architecture, authentication, API design, and deployment (Docker, Linux, Nginx)
- Mobile apps with React Native / Expo

SaaS platforms & product development
- Multi-tenant SaaS platforms built from scratch, including SSO, licensing, billing, and audit logging
- Founder and sole developer of Time-Dock, taken from idea to production launch

Automation & data engineering
- AI-driven data pipelines and document processing
- Workflow automation that saves teams hours every week

WHY WORK WITH ME

Over the past years I architected a multi-product SaaS platform for the energy sector, leading system design across an entire product suite, and built my own SaaS from the ground up. I understand the full journey: architecture, build, launch, and real users, not just isolated tasks. I write clean, maintainable code, explain my decisions clearly, and think about your product, not just the ticket in front of me.

WHAT YOU GET WORKING WITH ME
- Clear scoping upfront, so you know exactly what you'll receive
- Regular updates and clean handovers, no black-box development
- Maintainable, documented code you or your team can build on
- Honest advice: if there's a simpler or cheaper way to reach your goal, I'll tell you

I communicate reliably in English, German (native), and French, which makes me a strong fit for both international and German-speaking clients.

Whether you need a custom AI assistant, a web application, a data pipeline, or a knowledge system built on your own documents, I bring senior-level engineering and a product mindset to every project.

Let's talk about what you want to build.
