What teams book me for. Two typical cases.
Senior engineering power for your product team.
You have a product and more initiatives than your in-house team can deliver. I join on agreed days each week to tackle what matters most: new features, UI improvements, or technical refactoring.
What you receive
- Web apps, dashboards, customer portals and internal tools
- Interfaces with a focus on design, performance and usability
- Web3 frontends: wallet connection, live data, dashboards
- Custom tools and automation for recurring workflows
The process
Pricing & estimates
Transparent project estimates
- 1Intro call (approx. 20 minutes)We discuss your goals, requirements and scope.
- 2Written estimateYou receive a clear breakdown of estimated hours and deliverables.
- 3Budget approval & billingWork is billed against actual hours. If anything diverges from the estimate, I flag it early.
For orientation
100 EUR per hour, booked by the month
Fixed weekly days on a monthly retainer basis. Only actual hours worked are billed. All prices net.
One-week code sprint: audit, stabilization and immediate fixes.
The app is live, but recurring bugs and sluggish releases are slowing your team down. Over a dedicated five-day sprint, I audit the codebase, fix the most pressing issues, and outline a clear roadmap for long-term health.
What you receive
- Thorough architecture audit: solid foundations vs. stability and security risks
- Automated test coverage for mission-critical workflows
- Immediate resolution of high-priority bottlenecks within the sprint
- Actionable roadmap of recommended next steps – documented in plain language

The scope is a focused 35-hour sprint. If our initial call reveals that a single week cannot meaningfully move the needle, I will say so upfront. All prices net.
Automated quality gates before every production release.
In complex applications, isolated changes can introduce subtle regressions elsewhere. I protect everything I build with automated CI/CD pipelines and regression tests. Every commit must pass all quality gates before being deployed. Here is how that looks in practice:
Simulate a change in
Change submitted
A code change is pushed in Orders. Before deployment, the entire application undergoes automated linting, type-checking, and test suites.
Test fails – release blocked
The change triggered an unexpected regression. The automated pipeline halts immediately – broken code never reaches your users.
Fixed, verified, and deployed
The regression is resolved, the test suite turns green, and only then is the release securely promoted to production.
$ lint: checking code style…
An illustrative scenario modeled on a real CI/CD pipeline run. Automated test suites systematically catch regression defects before they impact customers.
Working relationship. Direct, transparent, and dependable.
Dedicated point of contact
You communicate directly with me – and I am the engineer who implements your code.
Transparent time tracking
Every hour is logged with precision. Monthly invoices itemize exactly what tasks were completed.
Engineered quality
I only hand over tested code, and I proactively flag technical risks or uncertainties as soon as they arise.
Full IP ownership
All code, architecture, and design belong entirely to you. Handoffs to internal teams or other developers are seamless.
Retainer-based monthly bookings. Predictable engineering bandwidth.
I dedicate agreed days of the week to your project, scheduled on a monthly retainer basis. No opaque packages: you only pay for actual hours logged.
- Dedicated weekly days, booked on a monthly basis
- Itemized monthly invoices with transparent time tracking
- Two weeks notice to the end of any month on both sides
- No single-day ad-hoc bookings
Per hour

Remote & focused deep work
I work fully remotely with flexible scheduling. I am available for sprint ceremonies, pair programming, and standups by arrangement. Instead of all-day chat distractions, I prioritize dedicated deep-work blocks – ensuring your roadmap moves forward swiftly and with high code quality.
Good to know before you book.
- How flexible is the engagement?
- Work is billed on time and materials. Either party can cancel with two weeks notice to the end of any month.
- Can you onboard into our existing codebase and team?
- Yes. Having worked in agencies and SaaS product companies for years, I am well versed in navigating complex codebases and established team workflows.
- Who owns the code?
- You do. 100% of all code, assets, and documentation are transferred to you – with zero vendor lock-in.
- What falls outside your core focus?
- Native mobile apps (iOS/Android App Store), Windows desktop applications, and bare-metal server management. If your initiative requires these, I will be upfront in our initial call.
