I'm Jan-Niclas Reese – a Product Owner with more than 13 years of experience in software development, from idea to delivery. I connect user needs, business goals and technical feasibility so that requirements turn into solutions that work in everyday use. Alongside my full-time role, I take on selected freelance projects – websites, web apps and mobile apps, from first idea to release.
I started as a developer – first with Objective-C and Swift on iOS, later on the web. Over the years the question "Are we building the right thing?" has interested me more than the pure "How do we build it?".
Today I work as Product Owner for SaaS-Produkte at RR Software GmbH. I like teams that take responsibility, short feedback loops and products that explain themselves within a few clicks.
Users first
Good products emerge where real problems become visible. I start with people and jobs to be done, not with features.
Engineering empathy
More than 13 years around software development help me estimate effort realistically and work with teams on equal footing.
Clarity over buzzwords
Plain language, clear priorities and roadmaps that still hold up three months in.
Focus
Focus between product, technology and delivery.
I connect business needs, technical feasibility and fast feedback loops into clear next steps.
Websites, web apps, mobile apps and AI strategy – from idea to release.
Alongside my full-time role, I take on selected freelance projects – from first concept to production release. I combine product ownership with hands-on delivery and use modern AI tooling as part of my workflow to turn ideas into solid results more quickly.
Clear, fast websites that showcase your positioning, offer and sales flow – technically clean, SEO-friendly and built in your design language.
Concept, copy sparring and UI implementation
Modern stacks (React, TanStack, Tailwind)
SEO fundamentals, analytics and contact flow
Web apps
Internal tools, customer portals or MVPs for new product ideas – from requirements and data model through API to a usable frontend.
Discovery, user stories and prototyping
Frontend (React/TypeScript) and backend integration
AI-assisted delivery with Claude Code, Codex & n8n
Mobile apps
Native iOS with Swift and SwiftUI
React Native for cross-platform MVPs
Store release, reviews and ongoing evolution
AI strategy & adoption
Practical guidance on integrating AI sensibly into product work and development – from assessing where it adds value to introducing workflows that teams and product owners can actually use.
Selecting and rolling out AI tools that fit the development and product workflow
Assessing where AI genuinely helps the team and process (and where it doesn't)
Coaching and sparring for product owners and teams using AI-assisted development
Early product ideas often rest on assumptions that haven't been validated yet.
My contribution
I use research, AI and quick prototypes to sharpen questions, make first solution paths visible and feed insights into further planning early on.
02
Translating domain needs into actionable requirements
Starting point
Domain requirements, user needs and technical constraints don't always speak the same language.
My contribution
I translate business goals into clear, understandable requirements and build shared understanding across stakeholders, design and frontend and backend teams.
03
Slicing and prioritising work sensibly
Starting point
Oversized or unclear initiatives make estimates unreliable and delay the delivery of usable value.
My contribution
I break requirements down into transparent work packages, clarify dependencies and prioritise together with the team by business value, risk and feasibility.
04
Planning iterations realistically
Starting point
Roadmaps need to give direction and remain flexible enough for new insights.
My contribution
I plan work packages and iterations based on available capacity, technical dependencies and business priorities. Progress and decisions stay transparent for everyone involved.
05
Gathering feedback early and adjusting course
Starting point
The later a wrong assumption becomes visible, the higher the cost of correcting it.
My contribution
I set up early feedback loops with users and stakeholders, review interim results and adjust priorities when needed. That way we spot missteps early and invest deliberately in solutions that hold up.
Responsible for roadmap, prioritisation, requirements and the collaboration with customers, stakeholders and frontend and backend teams for a SaaS solution in education and event management. Accompanying the design process and UI/UX alignment are part of the role.
