I'm Ronan — a software engineer with over a decade of experience across enterprise networking, fintech, and data platforms. I've led engineering at IPknowledge, built network infrastructure tooling at Aruba (Hewlett Packard Enterprise), and shipped everything from SD-WAN management platforms to AI-powered developer tools. Now I work independently, helping companies build software that holds up when it matters.
Based in Amsterdam and available remotely, I specialise in fintech engineering, data platform architecture, and ERP integration with Microsoft Dynamics 365 Business Central. BSc in Computer Software Engineering from Hogeschool Leiden. I care about clean code, reliable systems, and delivering on time — no hand-waving, just solid engineering.
What does a typical engagement look like?
Most projects start with a discovery call to understand your needs. From there, I provide a clear proposal with scope, timeline, and pricing. Engagements range from short sprints to multi-month builds, depending on what you need.
How do you handle pricing?
I work with fixed-price proposals for defined scope, or time-and-materials for ongoing work. You'll always know the cost before we start. No hourly billing surprises.
Do you work with startups or established companies?
Both. I've led engineering teams at enterprise companies like Hewlett Packard Enterprise and built products at startups from scratch. The principles are the same — ship reliable software, on time.
Can you work with my existing team?
Absolutely. I embed with your engineers, follow your processes, and communicate in your tools. I'm here to accelerate your team, not replace it.
What is your tech stack?
TypeScript, Node.js, Python, Rust, Swift, Java, C/C++, C#, PostgreSQL, and cloud platforms (Cloudflare, Azure). For ERP work, AL and Dynamics 365 Business Central. For networking, SD-WAN and infrastructure tooling. I pick the right tool for the job, not the trendy one.
Where are you based and what timezones do you cover?
Based in Amsterdam (CET), but I've worked with teams across Europe, the UK, and North America. Async-first communication works well for distributed teams.
Have a project in mind?
I'd love to hear about it.
I typically respond within 24 hours.
