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 -

I’m a full stack developer with over 10 years of experience building all kinds of digital products—from websites and mobile apps to blockchain platforms, embedded systems, and AI-powered solutions. I’ve worn a lot of hats over the years, but the common thread has always been solving real problems with smart, reliable tech. Whether you’re looking to launch something new or need help improving what you’ve already built, I’m here to jump in and make it work. -Web & Mobile Apps: Clean, responsive designs and solid backend logic. I work with tools like React, Vue, Node.js, Django, Flutter, and more to build apps people actually enjoy using. -Embedded Systems & IoT: I build smart, connected hardware using platforms like Arduino, ESP32, and Raspberry Pi. From prototyping to production-ready firmware, I work with C/C++, MicroPython, and platform-specific SDKs to control sensors, motors, displays, and more. I also integrate these systems with web and cloud services—often adding AI for tasks like real-time data analysis, voice interaction, or image recognition at the edge. -AI & Machine Learning: I integrate tools like GPT-4, Whisper (speech-to-text), and DALL·E into web and mobile platforms—automating workflows, building chatbots, content generators, or even custom AI copilots for your users or team. I also work with Python-based ML frameworks like TensorFlow and PyTorch for custom models and training. -Blockchain & Smart Contracts: I’ve developed and audited smart contracts (mainly Solidity) and built dApps that connect seamlessly with Ethereum, Solana, and BNB networks. Let’s bring your vision to life with clean architecture, scalable code, and tech that lasts. I’m ready to contribute as your long-term tech partner or on-demand expert. less -
