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. • Web automation and browser extensions. Chrome (Manifest V3) extensions, Playwright automation, and the messy real-world problems that come with anti-bot systems and live sites. 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. Every project I've delivered here is 5 stars, and a good share of my clients come back. 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.

Working with Helgi S. was fantastic. Unlike many developers who just rush to finish the job, he genuinely cares about client satisfaction. He was attentive to my requests, precise, and highly professional. I also really appreciated his fair pricing; he respected my budget from the start and worked perfectly within it. I am very satisfied with his high-quality work and would gladly collaborate with him again anytime. Highly recommended!

DevOps Engineer: Minimalist Linux Mail Transport (MTA) & Netplan /28 Subnet Routing

Helgi is an absolute master of enterprise mail infrastructure. He took a bare-metal Hetzner node and built a bulletproof, high-concurrency open-source Postfix + Mautic architecture with precision. He secured our Port 25 unblock on the first try, configured flawless rDNS across a /28 subnet, and delivered containerized single-tenant environments with a comprehensive Runbook. Exceptional communication and delivered ahead of schedule. Will definitely hire again for future clusters!

Direct Manager

I am writing to give my recommendation for Helgi, who worked with us at Nordvik Digital AS as a developer for two years. Helgi was responsible for building and maintaining several of our internal systems and customer-facing applications. He is very skilled in .NET and also took on frontend work when it was needed, which was not something we expected when we hired him. He has a good understanding of the whole picture, not only the code but also servers, deployment, and how things should work together. He is the type of person who finds solutions on his own. We had a situation where our deployment process was manual and took many hours each time. Helgi set up automated pipelines and containerization so that everything went much smoother. This saved us a lot of time and reduced errors. What I appreciated most is that he is honest and straightforward. If something is not possible or will take longer, he says it directly. He works well in a team but is also very capable of working independently, which for us was important since we are a small company. I can recommend Helgi for any development position. He will be a good addition to the team. Best regards, Petter Haugen Technical Lead Nordvik Digital AS Ålesund, Norway

Self-Hosted AI Agents with Claude Code and Proxmox

2025

dev.to

A walkthrough of building a personal autonomous agent platform on a single Proxmox host: Claude Code as orchestrator, role-specific worker VMs (backend, frontend, reviewer, devops, testing) dispatched over JSON-RPC. Covers the practical bits — keeping credentials fresh across worker users, scoping tasks so a 5-minute Sonnet run beats a long Opus one, and the operational scaffolding (memory hygiene, session notes, async kanban) that makes a one-engineer setup actually work.
