I build robust, production-grade software across multiple domains, with a particular specialization in algorithmic trading systems. I'm equally comfortable architecting a complex Expert Advisor, delivering a full-stack web application, automating a manual workflow, building a Telegram bot, or extracting data at scale from the web. Hundreds of clients have hired me for one type of project and returned for something completely different, because the underlying engineering quality and communication is consistent. What I build: Trading Systems (my deepest niche) • MetaTrader 4 and 5: Expert Advisors, custom indicators, scripts, optimization, backtesting • TradingView: Pine Script strategies, screeners, alert systems • NinjaTrader and similar platforms: automated strategies and indicators Software Engineering (broader practice) • Backend and APIs: C#, .NET, ASP.NET Core, SQL Server, RESTful services • Desktop Applications: WPF, Windows Forms, native Windows tooling • Web Applications: full-stack builds, dashboards, admin panels, integrations • Automation and Scraping: data extraction, scheduled jobs, workflow automation, Python tooling • Bots and Conversational Tools: Telegram bots, Discord bots, chatbot integrations, alert and notification systems • Integrations: payment gateways, third-party APIs, brokerage connections How I work: structured phased delivery, transparent milestones, no hidden scope-creep charges, deep requirements alignment before coding, and unlimited post-delivery support. I'm comfortable joining Zoom or screen-share sessions for briefs, walkthroughs, and live debugging. NDAs welcome. Whether you need a high-performance trading bot, a custom internal tool, a Telegram bot, a scraper that survives anti-bot defenses, or a full-stack web app, message me 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 -

I bring two skill sets that rarely come together: the developer who can build and maintain your site, and the engineer who can read your sensors and get their data onto a screen. Web & eCommerce I build and maintain fast, secure WordPress and WooCommerce sites for businesses that need them to actually work — not just look good. This covers custom PHP plugins and snippets, MySQL and WP_Query optimisation, REST API integrations, Shopify stores, on-page technical SEO, and Linux server administration (deployment, hardening, backups, performance tuning). My method is diagnosis before code: I find the root cause of a problem before touching a production site, back up before changing anything, and test in staging first. Industrial IoT & Instrumentation I develop firmware and data-acquisition systems for real hardware: multi-sensor UART/RS485 reading, Modbus RTU, and STM32/ESP32/Arduino, with robust SCADA and PC visualisation and real-time logging. On the software side, I build acquisition and monitoring dashboards in Python (Streamlit, Dash) and Node-RED, and deploy on Azure, AWS, or Linux. How I work Clear communication, honest scoping, and deadlines met. I quote what a project actually needs — no scope surprises — and I'm looking for long-term working relationships, not one-off jobs. Custom solutions built for your goals, never generic templates. Tell me what you're building and I'll tell you honestly whether it's a fit and how I'd approach it. less -
