I build web products, automation systems, and mobile apps for founders and small teams.
Work directly with one senior engineer to scope, build, and ship the product surface or workflow the business actually needs next.
What I Build
Three focused service areas built around the real workflows, tools, and customer flows that matter most.
Web Products
Custom software for founders and small teams who need a focused product, portal, or internal tool.
- SaaS MVPs
- Client portals
- Internal dashboards
- Admin panels and back-office tools
- Business workflows built as web apps
Automation & AI Systems
Practical systems that reduce manual work, connect tools, and add AI where it creates real business leverage.
- Workflow automation across forms, spreadsheets, and internal tools
- AI assistants for business operations
- Document processing and data extraction
- Request triage, routing, and summaries
- Support and operations workflows powered by AI
Mobile Apps
Focused mobile products built for a specific user flow, customer experience, or business process.
- Companion apps for existing products
- Mobile MVPs
- Customer-facing mobile tools
- Internal mobile apps for teams in the field
- Workflow-based mobile experiences

How I work
- Clear scope before build work expands.

- Delivery that is maintainable after launch.
What founders hire me for
A senior engineer who can scope clearly, build directly, and ship the part of the product or workflow that actually matters next.
Clear scope before code
I help reduce ambiguity early, so the first version is realistic, buildable, and tied to an actual business need.
Direct execution
You work with the engineer doing the thinking and the implementation - not through layers of agency process.
Systems that hold up in practice
I focus on products, internal tools, and automations that need to work reliably in day-to-day operations.
Clean handoff and next-step readiness
The result is maintainable, extendable, and structured so it can be improved without rewriting everything later.
Pricing
Clear engagement options for different stages of work.
Choose the format that matches the level of clarity, delivery scope, and continuity you need right now.
Discovery Sprint
€1,900
A focused starting point for projects that need clarity before implementation. Best for turning an idea, messy process, or technical uncertainty into a concrete build plan.
- Best for founders and small teams who know the problem but need structure
- Scope clarification and business/technical alignment
- Review of constraints, risks, and implementation options
- Clear recommendation for the best next step
- Written summary with suggested scope and delivery direction
- Ideal before a larger build or automation project
Focused Build Sprint
From €4,900
A fixed-scope build engagement for one defined feature, workflow, or product milestone. Best when the outcome is clear and needs to be shipped without unnecessary process.
- Best for one specific deliverable with a clear goal
- Can cover a feature, internal tool, dashboard, client portal, workflow, or MVP milestone
- Direct communication with the engineer doing the work
- Implementation, testing, and handoff included
- Clear scope boundaries before work starts
- Good fit for teams that need fast execution on a well-defined problem
Build Partner
From €7,500 / month
Ongoing product and engineering support for teams that need a reliable senior build partner. Best for continuous development across product, automation, AI workflows, and technical improvements.
- Best for ongoing roadmap execution
- Suitable for web products, internal systems, automation, and AI-assisted workflows
- Prioritized delivery based on current business needs
- Direct collaboration without agency overhead
- Flexible across multiple related workstreams
- Ideal for teams that need continuity without hiring full-time
If the work overlaps product, automation, AI, and mobile, the first reply will recommend the cleanest engagement shape instead of forcing it into the wrong package.
