Developer Accountability Coaching & Frontend Mentor

You don't need another course. You need someone watching.

I'm a Lead Engineer at GROPYUS with 18 years building software at Zalando, JUMO, and GROPYUS. I've led teams, shipped products, and mentored dozens of developers from junior to senior. The pattern I've seen over and over: developers don't fail because they lack knowledge. They fail because nobody holds them accountable.

Developer accountability coaching is what separates those who complete courses from those who actually ship code and land jobs. As a frontend developer mentor, I specialize in helping career changers, junior developers, and non-technical founders ship real projects.

Google can teach you React. YouTube can teach you TypeScript. But neither of them will text you on Tuesday asking why you didn't push that commit.

That's what I do.

Choose your path.

Select the level of guidance you need to ship your next milestone.

How I Work With Developers

🎯 Accountability-as-a-Service

What it is: Your fitness trainer for coding. Weekly async check-ins where you report progress and I respond with feedback, pushback, and direction.

How it works:

Monday: You send me a structured update (5 questions via form): What did you accomplish? What blocked you? What's your #1 goal this week?
Tuesday: I respond (5-10 min review per client): Acknowledge wins, provide one observation or pushback, end with "What's the first action today?"
Ad-hoc: Direct WhatsApp/Telegram access for "stuck" moments. Quick voice notes. 2-3 min max response time during working hours.

Who it's for:

Junior-to-mid developers building portfolio projects
Career changers who know what to do but need external accountability
Job seekers preparing for interviews who keep procrastinating
Anyone who needs a senior engineer watching their progress

Time commitment: 15 minutes per week from you. One focused hour of my attention per month.

What makes this different: I'm not a bot. I'm a Lead Engineer at GROPYUS with 18 years of pattern recognition. I've seen your bug before. I know why you're stuck. And I'll tell you exactly what to do next.

🧠 Fractional CTO for Founders

What it is: I'm your "technical co-founder lite." Review technical hires/contractors, audit codebases, advise on architecture, join key meetings, protect you from getting ripped off by agencies.

Time commitment: 4-6 hours per month (typically 2-3 calls + async reviews).

What I do:

Review technical hires – Screen developers, review portfolios, conduct technical interviews
Audit contractor code – Prevent vendor lock-in, assess quality, identify technical debt
Architecture decisions – Advise on tech stack, scaling strategy, API design
Meeting participation – Join key meetings with agencies, VCs, or technical partners
Build vs. buy recommendations – Help you decide what to outsource vs. build in-house
Roadmap reality checks – Tell you if your agency's timeline is realistic or BS

Who it's for:

Solo founders with budget and an idea but no technical co-founder
Small businesses with outsourced dev teams who need senior oversight
Agencies needing senior technical leadership for client projects
Anyone spending €5K+/month on development and not sure if they're getting value

Why me: 18 years across eCommerce (Zalando), fintech (JUMO), PropTech (GROPYUS), plus co-founding 2 startups = pattern recognition no junior CTO-for-hire has. I've seen the mistake you're about to make. I'll help you avoid it.

Frequently Asked Questions

Is there a way to try working together before committing?

Yes — book a Ship It Session (€50). One focused hour on a specific problem. You'll experience how I work, explain things, and give feedback. No obligation after.

Can I pause my accountability subscription?

Yes. Life happens. You can pause for up to 4 weeks per year without losing your spot. Beyond that, you will need to re-enroll (and I may be at capacity).

Do you work with complete beginners?

Yes, but only if you've already completed a beginner course (freeCodeCamp, Codecademy, etc.). I don't teach syntax. I teach how to actually ship projects and get hired.

If you're brand new (never written a line of code), start with a beginner course first. Come back when you've built 2-3 simple projects.

What timezone are you in?

Europe/Berlin (CET/CEST). I work with clients globally, but live sessions are typically 9 AM - 6 PM Berlin time. Accountability check-ins are async, so timezone doesn't matter.

What's the cancellation policy?

Accountability-as-a-Service: Cancel anytime, no notice period.

Build-With-Me: Full refund if cancelled before we start. After the session begins, no refund — you're paying for time together.

Fractional CTO: Monthly billing, cancel with 30 days notice.

Do you sign NDAs?

Yes, for Fractional CTO and Build-With-Me sessions where you're sharing proprietary code. Not required for Accountability-as-a-Service (you control what you share).

Ready to Ship?

Whether you need developer accountability coaching, a frontend mentor for technical guidance, or strategic CTO-level advice, I'm here to help you ship.
