I help businesses build, improve, and maintain software and infrastructure they can rely on. Clients usually come to me when they need someone who can take ownership—not just complete isolated technical tasks. I help launch new platforms, modernize existing systems, improve reliability and performance, automate operations, and solve problems that are slowing the business down. My focus is always the outcome: stable systems, smoother operations, less downtime, easier maintenance, and a setup that can grow with the business. I'm based in Germany and communicate fluently in English (C2), German (C1), and Romanian (native). I also operate my own hosting infrastructure, which can be useful for development, staging, testing, and deployment when a project needs it. You can expect clear communication, realistic commitments, and dependable follow-through. I'm also available after delivery for ongoing development, maintenance, monitoring, improvements, and long-term technical support. If you need someone experienced who can take responsibility for the technical side and stay involved long-term, I'd be glad to help. less -

Hi, I'm Elias, founder of Reupped Technologies LLC. Most software projects don't fail because of poor development—they fail because the wrong problems are solved first. That's why every project begins by understanding your business, your users, and the workflow behind the idea before writing a single line of code. For more than 20 years, I've helped startups, entrepreneurs, and established businesses build software that is reliable, scalable, and designed to grow with them. Whether it's a SaaS platform, AI-powered application, mobile app, marketplace, ERP, CRM, fintech product, or custom business system, my focus is always the same: build software that solves real problems while keeping future growth in mind. I handle the complete development process, including: • Product planning • UI/UX • Web development • Mobile apps • Backend architecture • API integrations • AI solutions • Blockchain • Cloud deployment • Long-term support What clients appreciate most isn't just our technical expertise—it's our ability to simplify complex ideas, ask the right questions, and recommend solutions that make sense for the business. If you're looking for a development partner who values communication, thoughtful planning, and long-term success just as much as clean code, I'd be happy to discuss your project. less -

I freelance on focused project work where the job is to solve a real problem and ship something that works. You get someone who reads the spec properly, asks the right questions, and hands back clean code without needing to be managed. My background is enterprise software: C#/.NET, ASP.NET Core, Entity Framework, background services, and the kind of API and data work that has to survive real users and real money. I bring that same standard to freelance projects: clean architecture, sensible error handling, and no shortcuts that bite you in production. What I build: • APIs and integrations. REST API design, third-party platform integrations, OAuth, webhooks, payment and booking flows. If it needs to talk to another system reliably, that's my lane. • C#/.NET backends. ASP.NET Core services, EF Core, migrations, background jobs and scheduled workers. • Python backends and automation. FastAPI services, data pipelines, scrapers, and automation scripts. Practical Python that does a job, not a science project. • SaaS and web apps. Full-stack work with React front-ends on Python or .NET backends, including multi-tenant systems and property-management and channel-sync platforms with live third-party data. • AI integrations. Assistants and MCP servers that answer from your own database or documents instead of guessing, and AI steps inside workflows you already run, with every query logged. • Infrastructure. Docker, Ansible and OpenTofu, high-availability database clusters, CI/CD and monitoring, so the thing I build keeps running after handover. • Web automation and browser extensions. Chrome (Manifest V3) extensions and Playwright automation for sites and web apps you have access to. How I work: I scope honestly up front. If something's a bad idea, I'll tell you before you pay for it. I favour the simplest solution that solves the actual problem over the most impressive-looking one. Communication is clear and async, no daily standups required and no chasing me for updates. A good share of my clients here come back for another project. From my latest large project: "Helgi embraced every challenge and consistently delivered beyond our expectations." If you've got a backend, API, integration, or automation problem, send me the details. I'll tell you straight whether I'm the right fit, what it'll take, and how long. less -
