Software development and modernization
Build, extend and simplify software in C++, C#, Python and JavaScript/TypeScript—from embedded and desktop systems to Linux services and full-stack web applications.
Senior freelance software consultant · Denmark and remote
Reliable software delivery for complex systems.
I am Rud Pedersen, a software consultant with more than 20 years of experience taking solutions from requirements and architecture through implementation, verification and deployment. I help teams improve existing systems, build new products and put AI-assisted development to practical use.
How I can help
Available for longer assignments and clearly scoped projects, working on-site or hybrid in Denmark and remotely with international teams.
AI and agentic engineering
Turn AI-assisted development into a controlled engineering practice with clear architecture, executable guardrails, focused context, independent review and measurable evaluations.
Architecture, quality and verification
Make complex and regulated systems easier to change and defend. Apply the necessary checks at the right level: static analysis, unit, integration, end-to-end and LLM evaluations where relevant.
Data products and visualization
Connect APIs and operational data to traceable transformations, interactive analytics and clear visualizations across web, 3D and XR interfaces.
Selected work
Products and supporting tools that demonstrate practical delivery, not just technical experiments.
AI-assisted data product
XR Data Explorer
A deployed conversational analytics product for exploring official statistics in Danish and English. It combines deterministic chart recommendations, traceable data transformations, saved workflows and collaborative web and XR visualization.
The codebase is developed with AI agents under explicit rules, guarded permissions, independent review and verification matched to each change.
Agent workflow
Task Tracker
A focused work record for human and AI-agent development. Plans, implementation, evidence, review and human verification stay connected to the task in a simple, inspectable system.
Repeatable product communication
Demo Capture
A story-driven pipeline that records real application behavior and turns it into repeatable narrated demos. Framing, timing and narration can be refined without driving the product again, while verification gates keep claims aligned with the running software.
Experience that transfers
More than 20 years across full delivery lifecycles, from requirements and architecture to implementation, test, commissioning and production support.
Regulated medical software
Architecture risk controls, implementation, testability and delivery infrastructure for Class C medical-device platforms and diagnostic instruments.
Avionics verification
Requirements analysis, test strategy, test-case design, automation, log analysis and troubleshooting for a large regulated avionics program.
Industrial and embedded systems
Control software for large marine engines, embedded signal analysis, Linux services and the tools needed to inspect, test and commission them.
Technology with context
Current full-stack and agentic product work is backed by long-standing experience in C++, C#, Python, verification and complex systems.
- C++
- C# and .NET
- Python
- JavaScript / TypeScript
- Node.js and REST APIs
- AI agents and OpenAI APIs
- Playwright and pytest
- Docker, Linux and CI
- Three.js, ECharts and WebXR
How I work
Solid solutions start with understanding the real need and end with evidence that the result works as expected.
- Listen before deciding — clarify the problem, constraints and success criteria before committing to a solution.
- Work systematically — make priorities, decisions, progress and risks visible throughout the assignment.
- Suggest improvements proactively — bring forward useful tools, methods and alternatives instead of waiting for detailed instructions.
- Keep the solution simple — use one clear source of truth, remove obsolete paths and avoid patchwork that makes the next change harder.
- Verify what matters — choose the necessary checks at the right level and deliver within the agreed time, scope and budget.
