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'm a backend engineer with a full-time role in the Norwegian financial sector, building production .NET systems where reliability and correctness aren't optional.

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 -

We work with both new and existing projects — whether you need a small fix, a highly customized website, a new feature, an eCommerce solution, a third-party integration, or a complete business application built from the ground up. Our main areas of expertise include: WORDPRESS & WOOCOMMERCE • Custom WordPress website development • Highly customized themes and functionality • Elementor development and customization • Custom plugins and integrations • WooCommerce customization • Complex product, pricing and checkout requirements • Performance, security and maintenance • Figma to WordPress development WordPress is one of our strongest areas, especially when a project requires more customization than a standard theme or plugin can provide. SHOPIFY • Custom Shopify theme development • Shopify 2.0 customization • Custom Shopify apps and private apps • Shopify API and webhook integrations • Custom eCommerce functionality • Product, pricing and checkout customizations • Store improvements and performance optimization CUSTOM WEB APPLICATIONS When a project needs something beyond WordPress or Shopify, we build custom applications using modern technologies such as: • React / Next.js • Node.js / NestJS • Laravel / PHP • PostgreSQL / MySQL • REST APIs and third-party integrations • AWS • Git and CI/CD This includes admin panels, dashboards, booking systems, business management platforms, SaaS applications, customer portals, internal tools, and other custom software. DEVOPS & DEPLOYMENT We can also take care of the technical side of getting an application into production — including AWS setup, servers, deployment, Git workflows, CI/CD pipelines, environment configuration, backups, and ongoing maintenance. UI/UX & MOBILE We work with Figma to create and implement clean, responsive interfaces and can also develop mobile applications based on your product requirements. SEO & PERFORMANCE We also help improve website performance and technical SEO, including speed optimization, Core Web Vitals, technical issues, and search-engine-friendly implementation. ⭐ 500+ Five-Star Reviews 🚀 2,000+ Projects Delivered 🌍 Working with businesses worldwide What matters to us is understanding what you actually need before jumping into development. For some projects, WordPress or Shopify is the right solution. For others, a custom application makes more sense. We choose the approach based on the requirements rather than forcing every project into the same technology. Whether you need a quick fix, an existing website or application improved, or a complete system developed from scratch, we're happy to take a look. Send us the requirements, even if they're not fully defined yet. We'll review them and suggest a practical way forward. less
